Create Your Campaign

From the Campaigns page, click Create a Campaign to get started.

2. Contact list: Click Select recipients to choose who will receive your campaign. You can select your contact list and, if your plan supports it, apply segmentation to target specific contacts. For more information, see our Segmentation Guide.

3. From / Subject Line: Configure the information recipients will see in their inbox, including your subject line, preview text, sender name, and sender email address. You can also add an optional reply-to address.

   Click the pencil icon to open these settings. See the section below for more details.

4. Content: Click Design email to select a template and create or customize your email using Mailjet's Email Editor.

To insert a countdown timer, open the Content panel and drag the Countdown Timer block into your template.

• Top
• Bottom
• Left
• Right

Click the 🔒 lock icon to link or unlink the values for symmetrical spacing.

Borders

In the Borders section, you can define the border weight to add an outline around the Countdown Timer.

• Set the weight to 0 for no border, or increase it to add thickness.

These options help you fine-tune spacing and layout for a polished design.

Brand Kit Logo Component

We’ve added a new "Logo" component to the email builder, making it even easier to integrate your logo into your templates.

Key Features:

• If you have a Brand Kit with a saved logo, a Logo component with a preview of your logo will appear in your builder.

  

• Simply drag and drop the logo into your template.
• The logo behaves similarly to an image block but:
  • It’s centered by default.
  • It doesn’t have the standard image toolbar, simplifying its behavior.
  • It will automatically adjust to the background color:
    • Light background → light logo variant.
    • Dark background → dark logo variant.
• Logo Redirect URL (if set in the Brand Kit) will automatically be applied to the logo.

Behavior When No Logo Is Available:

• If your Brand Kit doesn’t have a logo, the Logo component will be hidden in the builder.
• If a logo is deleted from the Brand Kit, the Logo component will no longer appear.

Managing Existing Templates:

• Logos already placed in templates will not be removed, even if you update or delete logos from your Brand Kit.
• If you replace a logo in the Brand Kit, previously created templates will retain the old logo.
• If you duplicate a template, the logo will be preserved in the duplicated version.
• If you delete a logo and later upload a new one, you must manually reinsert the new logo into your templates.

Sections

Add a Section to Your Campaign

You can build your campaign by adding sections. Then you add different elements (text, button, images, …) to each section. A section can have 1, 2, 3 or 4 columns, with varying widths.

Click on the section layout you want, then drag and drop it into your campaign.

Move a Section

Click in the section background then on the up or down arrows.

Duplicate a Section

Click within the section to highlight it, then click the duplicate icon on the right side of the screen.

Delete a Section

To remove a section from your campaign body, click within the section, then click the trash icon. Confirm the deletion by clicking on the red 'x' that appears.

You can also quickly delete a section or element, by dragging it to the content tools area.

Conditional Sections

You have the option to display a content section to certain people by applying a segment. The segment can be based on the user’s existing contact properties or by their user activity.

For example, you may want to display a promotional section to your female clients only or offer a discount code to clients who have not opened your previous newsletters in the last 3 months.

Please take a few minutes to review your current segments. If you need a refresher, please review our Segmentation Guide.

Click within a section to view its current conditional status. By default, all sections are shown to everyone.

To apply a segment:

• Click 'Add Condition'
• Click 'Only show to recipients who belong to the segment' and select a segment from the dropdown list.
• Click 'Save'

To remove a segment, simply click 'Edit' and select 'Show to all recipients'.

Pre-built Sections

A pre-built section can serve as a template that can be used and modified to meet the specific needs of the sender. Think of a pre-built section as a ready-made content block that provides a foundation for creating various types of emails or designs. This section already includes a combination of elements such as text, images, headings, buttons, and more, arranged in a visually appealing and coherent manner.

The primary reasons for using pre-built sections in a template are as follows:

• Time-Saving: Starting with a pre-built section saves time as it provides a starting point, reducing the need to create content or design from scratch.
• Design Consistency: Using a pre-built section ensures a consistent and professional look throughout the template. This consistency is crucial for brand identity and recognition.
• Structure and Layout: Pre-built sections offer a well-organized structure and layout, guiding the sender on how to present their content effectively.
• User-Friendly: Pre-built sections are designed to be user-friendly, allowing even those with limited design skills to create visually appealing templates.
• Customization: While the pre-built section provides a foundation, the sender can easily modify, rearrange, or add elements to tailor the template to their specific requirements.
• Flexibility: Senders can adjust fonts, colors, images, and other visual elements to align with their brand or style preferences.
• Consolidation of Best Practices: Pre-built sections are often created based on design best practices, ensuring the template adheres to effective design principles.
• Reusability: Once a pre-built section is modified to the sender's needs, it can be saved and reused as a personalized template for future use.

By using a pre-built section in a template and customizing it according to your needs, you can create visually appealing and well-structured emails or designs without the burden of starting from scratch. This flexibility empowers the sender to focus on their content and messaging while leveraging professionally designed elements to enhance the overall quality and impact of their communications.

Saved Sections

Tired of creating and updating the same header, footer or key sections in your campaigns and templates?

You can stop duplicating your efforts and start saving your important campaign/template sections with Saved Sections. 

Saved Sections allows you to save a part of your campaign or template (content, color, formatting) for use in your future Marketing, Transactional and Automation mailings.

All sections are saved into a Saved Sections Gallery where you can :

• Save your sections from the Email Editor to a Saved Section gallery
• Drop a saved section into a template or dynamically link* a section to many templates at once
• Work on draft versions to update sections without impacting the templates they are linked to
• Edit and publish changes to your sections, updating all templates they are linked to, with a single push of a button!

Regular vs Dynamically Linked

There are two types of Saved Sections:

• Regular Saved Section
  Copy your Saved Section to your template or campaign. Any changes made to Saved Section in the Gallery will not be reflected in your template.

• Dynamically Linked Saved Section

  ✓

  Availability

  This feature is included in the following plans.

  • X Free
  • X Starter
  • X Essential
  • ✓ Premium
  • ✓ Custom

  Link your Saved Section to your templates. When changes are published on a Linked Saved Section in the Gallery, all linked templates are automatically updated. Use the Link mode for sections that are used in many of your templates such as headers and footers.
  

Draft Sections and Published Sections

A Saved Section can be in Draft mode or in Published mode:

• Only Published Sections will appear in the 'My Saved Sections' menu in the Email Editor and can be added to your marketing template, transactional email, or included in an automated workflow.
• A Draft Section cannot be used in templates and will not appear in the 'My Saved Sections' menu in the Email Editor when designing your campaigns, templates, or automated workflows. Once you are satisfied with your section design and content, simply publish it to have it appear in 'My Saved Sections' in the Email Editor.

Section statuses can be seen in the Templates → Saved Section Gallery.

Create a Saved Section

There are two ways to create a new Saved Section:

• Use the Section Builder to design a new section
• Save a section from an existing template or campaign via the Email Editor

Using the Section Builder from the Saved Sections Gallery

Go to your Saved Sections Gallery which can be accessed from any Templates page.

To design a new section, click on 'Create a saved section'.

Enter a name for your new Saved Section, an (optional) description and then click 'Create' to continue.

Design your new section using the Section Builder, which is a mini version of the Email Editor.

Once your section is ready for use, just click on 'Save & Publish to gallery'.

And that's it - your first section has been published.

Click 'Back to my sections' to return to the Saved Sections Gallery to see your newly published section. It can now be used in your campaigns, transactional emails and automation workflows. :)

Keep reading to learn how to create a section from an existing template/campaign in Mailjet’s Email Editor, or jump to how to use My Saved Sections.

From an existing Campaign / Template via Mailjet’s Email Editor

Alternatively, you can also quickly save a section by dragging it to the Content Tools area, on the left of the builder.

Once you choose the name and click on 'Save', the section will be added to your Saved Sections Gallery. And it will also be automatically linked to the template you created it from (Premium Feature only). If you are on a Free, Starter, or Essential Plan, or saved the section from a campaign, no link will be made.

Using Saved Sections in Mailjet’s Email Editor

You can view and insert your Saved Sections from the Email Editor.

👉Insert a Saved Section into a Campaign (Regular Mode only)

Saved Sections can only be copied as a regular section into your marketing campaigns, with no link to the Saved Section Gallery. Any changes made to the section in your campaign are local only (Dynamically Linked Sections can only be added to a template and will be covered in the next part of this guide).

To insert a section into your marketing campaign, click on Drag & Drop Sections → Saved and drag-and-drop a section into the campaign.

Make the changes to the section. Then save the changes as a Draft, or Publish the changes to have them propagate to all other linked templates.

Then click 'Return to my template' to go back to the Email Editor. 

Dynamic Linked Sections and Downgrading from Premium Plan

If you create Dynamically Linked Sections while on a Premium Plan, and then downgrade to a Essential, Starter, or Free Plan, the links between sections and templates will become dormant. And any changes made to an existing Linked Section will not be reflected in the linked templates.

If you upgrade again to a Premium Plan, the dormant links will become active again, and you are free to create new Linked Sections.

Locking a Section

Protect your email design and brand identity from accidental changes with Section Locking.

Give your Developers, Designers and other team members the ability to control who can edit or delete content within individual sections of a Campaign or Template, as well as the entire Design & Layout.

Assign Locking Permissions

Give locking permissions when sharing your account with collaborators and team members.

Choose the predefined role of Manager, Developer or Designer role which includes locking ability, or create a custom role. (For more information on User Roles, please go to the Account Sharing Guide)

Locking a Section (via Mailjet’s Email Editor)

To lock or unlock a section of a campaign or template in the Email Editor, simply click on the 'Content Locking' icon.

If you do not have permission to lock or unlock a section, a modal will appear informing you to contact the account administrator to acquire the permissions. 

Or if you are on an Essential plan, you will need to upgrade to a Premium Plan. 

If you have permissions, the 'Content Locking' modal will appear with the following levels of locking:

• Unlock everything (default)
  There is no locking and the section is completely open for modification, including deletion.

• Allow text and images edition only
  In other words, it is content-editable only. No changes to the section design (padding, alignments, colors, etc) can be done and no content blocks can be added or removed from the section. The section can be moved and, if checked, the section can be deleted or duplicated.

• Lock everything.
  The section is fully locked down and no changes can be made, except moving the section. 

Once you selected a level of locking, click 'Confirm' to save your changes.

Viewing Locked Sections

Let's look at how the different locked sections will appear in the Email Editor to users who do not have permissions to lock or unlock sections.

👉Unlocked Section

The section appears as normal in the Email Editor - with full content block menu icons and section buttons (section options, move up/down, copy, save section, delete).

👉Section is content-editable only (with no section deletion)

The section can moved; but all other section buttons are hidden (section options, copy, delete, save section).

Locked Section:

Not Locked Section:

And no content blocks can be added or deleted to a content-editable only (no deletion) section.

When clicking on a content block within a (locked) section, the options available will be for content editing. The icons associated with block design, or block duplicating or deletion will be hidden

All options for the content blocks (text, image, button, etc) are the same as the "Section is content-editable - with no selection deletion" locking option.

Section fully locked

A section that is fully locked has no available options or menus. The section and any content blocks within, cannot be modified in any way but the section can be moved and saved.

Locking Global Page Design

Account owners and users who have locking permissions can lock the global design settings at the template level which includes:

• Page Layout (responsive design) and background color
• Text styles (headers, paragraphs, link styles)
• Logo Options

To access this locking option, go to the 'Settings' tab in the Email Editor, then click on 'Page design locking'.

The 'Page design locking' section offers two options:

• By default, the first option is selected which allows the Global settings to be modified by users with the permission to lock sections.
• Click the second option to lock all Global settings (except for Language). A small 'lock' icon will appear beside the locked options.

Real-time Collaboration

Real-time collaboration allows multiple users to simultaneously work on the same email template or campaign. This functionality enables teams to efficiently create, edit, and finalize email templates without the delays associated with sequential editing or exchanging drafts through email or other communication channels.

Key Features:

1. Simultaneous Editing
   Multiple users can access and edit the email template at the same time. Changes made by one user are instantly visible to others, ensuring that all collaborators are working with the most up-to-date version of the template.
2. Comments and Suggestions
   Collaborators can leave comments or suggestions directly within the email template. This feature facilitates discussion and feedback within the template itself, reducing the need for external communication channels or lengthy email threads.
3. Live Preview
   A live preview allows collaborators to see how the email will appear to recipients as edits are made. This helps ensure that the final email template is visually appealing and functions as intended across different email clients and devices.

With the Real-time Collaboration feature, you can do just that – share your account with your team and have multiple people work in the Email Editor simultaneously!

Collaborating Users List

When two or more users are simultaneously working on a template in the Email Editor, each is represented by a colored circle displaying their initials. You can hover over any circle to see the user's full name.

Users Editing Sections & Blocks

The block or section being edited is highlighted in the color associated with the user making the changes, with their full name displayed within that area. You can also see the updates that other users are making in real-time.

Comments in real-time

You no longer have to wait for your colleagues to finish editing an email before you can review it. While a section is being edited, it will be temporarily locked, but you'll still be able to see the changes as they happen.

Additionally, the built-in commenting feature allows you to communicate effortlessly with your team directly within the email editor. This real-time collaboration streamlines the email design process, making it more agile and efficient.

Manage Template Publishing Access for Shared Accounts

To avoid the accidental publication of incomplete templates, it is recommended that the primary account holder limit publishing permissions to specific users. This approach ensures that templates are only published after they have been reviewed and approved.

Collaborators can be granted access to create and edit templates, but not to publish them. This configuration allows the final publishing step to be managed exclusively by authorized individuals.

Header & Footer

The Header

The campaign header contains two important elements:

• Email Summary: A short introduction displayed within your email header. To customize it, click directly on the text in the Email Editor and make your changes.
• View online link: Allows recipients to open and view your email in their web browser. This link is automatically generated by Mailjet, so no additional configuration is required.

The Footer

The default campaign footer includes an unsubscribe link and recipient information. The special variable [[EMAIL_TO]] automatically displays the recipient's email address.

You can customize the footer to match your brand. Simply click within the footer section and use the available toolbars to adjust its content, formatting, and design.

The default unsubscribe link uses a special variable: [[UNSUB_LINK_LOCALE]]. This variable generates the unsubscribe link in the appropriate language for your recipients.

You can modify the footer text and design as needed, but you must keep a valid unsubscribe link to allow recipients to unsubscribe from your mailing list.

Unsubscribe Page Language

Use this setting to choose which language version of your unsubscribe page is shown when a contact clicks the unsubscribe link in emails using this template. The language you select here applies only to the unsubscribe page, not to the rest of your email content.

Open the Languages panel, go to Unsubscribe link, and pick the desired language from the drop-down list. The languages available here depend on the unsubscribe experience you’ve set up for your recipients (Default, Custom page, or Preference center).

With our Brand Kit feature, you can effortlessly maintain brand consistency across all your email templates and campaigns. The Brand Kit allows you to set branding elements, such as logos, fonts, and colors, that apply globally to ensure uniformity. 

To learn more about setting up and using your Brand Kit, please check out this guide: Mailjet's Brand Kit.

Global Style Settings

With a couple of clicks, easily format the text styles of all your paragraphs, headers and hyperlinks within your newsletter or template.

To access the global text styles, click on the 'Settings' tab.

As the name suggests, the "Global Style" option will set the font family and color for all the elements listed (Headers, Paragraphs, Links) as well as the newsletter header and footer for the current template.

You can then further customize the styling for each of the Headers, Paragraph and Link elements.

And lastly, if you want to have a different text style for a certain header or paragraph in your campaign, simply style the text as usual with the section toolbar.

Logo Options

When you create a campaign using the Email Editor, a Powered by Mailjet logo is automatically added to the footer.

You can choose from five different logo color schemes in the Logo Options section of the Settings tab.

To remove the Mailjet logo, select No logo. This option is available on paid plans other than the Starter plan.

On the Free and Starter plans, selecting No logo will prompt you to upgrade your subscription.

Import Custom Fonts

Add custom Google fonts or hosted web fonts to your marketing newsletters, transactional and automation templates using the Email Editor.

To add a custom font, click on the Font Family drop down list from within a text element, and select 'Add a web font'.

At this point you choose to add a one of over 800 Google Web Fonts or link to a hosted web font via a CSS file.

Add A Google Font

Start typing a Google Font name. Once you select a font from the predictive list, the preview window will display the new font. You can also change the text in the 'your font' preview section (up to 15 characters).

The preview section also displays a fallback font.

While some major email clients do support custom web fonts (Apple Mail, Android Mail, iOS Mail, Outlook 2016 OSX…), be aware that some others don't, such as: Gmail, Yahoo! Mail and Outlook 2003. In these cases, the fallback font will be displayed instead of the Google font.

Once you selected a custom font, click 'Add font'.

All custom fonts will be added to the top of the font list in alphabetical order.

Add Other Web Fonts

To add your own custom web font, enter the URL to the CSS file that contains the web font information. A new drop down list will appear showing all the fonts found in the CSS file. Simply click on the font you want to import and then click ’Add font’.

Add a Fallback Font

A fallback font is a backup font that appears when the recipient’s email client doesn’t support or can’t render the primary font used in your design—whether it's a custom or web-safe font. It ensures that your message remains legible and visually consistent across different email clients.

To add a fallback font to your email template:

1. Click the gear icon (⚙️) in the left-hand panel of the Email Editor to open the Settings menu.
   
2. In the Settings panel, expand the Text styles section. You’ll see options like Paragraph, Heading 1, Heading 2, and more.
3. Scroll to the bottom and click Add fallback font.
4. Select a web-safe font from the dropdown (e.g., Arial, Verdana, or Times New Roman). A preview will appear below the selection.
   
5. Click Save to apply the fallback font.

The fallback font will now be used automatically if your primary font isn’t supported by the recipient’s email client.

Personalizing Content

Make your emails more relevant by using contact properties to personalize your content. You can insert variables into your email body, subject line, and preview text to display information specific to each recipient.

Personalize Your Email Content

To personalize text within your email, select the text block you want to customize in the Email Editor. From the text toolbar, click Variables.

Select the contact property you want to use, such as firstname, lastname, or another property available in your contact list.

Enter a Default value to display if the selected contact property is empty or unavailable. For example, if a recipient does not have a first name saved, you can display "Everyone" instead.

Click Insert to add the variable to your email content. Mailjet will automatically replace it with the corresponding contact information when the email is sent.

Personalize Your Subject Line and Preview Text

You can also use contact properties to personalize your campaign's subject line and preview text.

Unlike email body content, these fields are managed directly from the Campaign details page rather than inside the Email Editor.

To personalize these fields:

1. Return to the Campaign details page.
2. Click the pencil icon in the From / Subject Line section.
3. Locate the Subject or Preview text field.
4. Click Insert variable next to the relevant field and select the contact property you want to use.
5. Click Save to apply your changes.

For more information about configuring these fields, see Configure Your Campaign Metadata.

Manage your Mobile View

You can arrange how the columns in each section of your message will appear on a mobile device: Stacked (default) or Side by Side

To change a column display, click on the section background then click on the 'Selection Options' icon.

Check the 'Keep multiple columns on mobile' options to display columns side by side. A small blue icon will appear in the section indicating the columns will be shown side by side on a mobile device.

Click on 'Preview & Test' to view how your columns will look side by side.

Responsive Design (Fullwidth vs Boxed)

Our tool allows you to build responsive design newsletters. This means that your newsletter can respond and adapt accordingly to the width of your viewing screen. Your campaign will look awesome whether you view it on a computer/laptop, mobile phone or tablet.

The Setting Tab gives you two options for responsive design:

• Fullwidth: Your campaign width will automatically adjust to the width of the viewing screen.
• Boxed: The main campaign body width is static, regardless of the viewing screen.
  
   

Enable Dark Mode Optimization

The Dark Mode Optimization feature improves how your email displays in dark mode by adding meta tags and CSS rules to your design. This helps prevent unexpected color changes when recipients use dark mode in their email clients. Note that some clients may still override these settings.

To enable Dark Mode Optimization:

1. Click the gear icon (⚙️) in the left-hand panel of the Email Editor to open the Settings menu.
   
2. Expand the Email client rendering section.
3. Toggle the Dark mode optimization switch to enable it.
4. Click Preview to see how your email will appear in dark mode.

Enabling this option helps ensure your email design remains consistent and accessible across a wider range of devices and email clients that support dark mode.

Preview Your Campaign

To preview your campaign click on the Preview & Test → Preview Email.

Your campaign can be previewed on different devices:

Email Preview

The Email Editor provides the possibility to test how a template or campaign will look on different devices (screen sizes). This Preview gives a view only of the responsiveness of the design, however, each email client has its specifics.

The problem with email is that every inbox – Apple Mail, Outlook, Yahoo!, Gmail and all of the others – render the same email very differently. While we’re doing our best to offer the best result on all email clients, we have no control over the rules defined by those clients. For example, even Gmail will not render Google fonts and there’s nothing anyone can do about it (except Gmail, of course)!

Because of this, it’s very important to test your email across all of the email clients your audience is using to make sure they’re seeing your message the way you expect them to.

To help you do this, we have created the Email preview feature that will help you preview your email exactly as it will be displayed when read by your contacts.

Send a Test email

You can send a test email (campaign) up to 10 recipients at any time.

To send a test campaign, click on the Preview & Test → Send a test mail.

Save Your Campaign

To save your campaign, select 'Save my email' or 'Save and exit'.

To save your campaign as a template, select 'Save as a template'.

Let's step through saving your campaign as a template:

The first time you save a campaign as a template, you will need to enter a template name. You can overwrite the default template name or enter a new template name.

For this example, a new template name will be entered. Then click 'Confirm' to create your new template.

To view your new template, click on 'Back to template selection' from the main menu, then click 'Use one of my templates'.

Send Your Campaign

2. Review your campaign name and selected recipients to make sure everything is correct.
3. In the From / Subject Line section, verify your subject line, preview text, sender name, and sender address. If you've added a reply-to address, review it as well. Click the pencil icon to make any necessary changes.
4. Check the Content section to ensure your email design is ready and all required campaign details are completed.
