What are Templates

A template is a predesigned layout that you use as the foundation for your mailings. Simply select a template that you like and then customize the content, colors, images to your liking. You can create a marketing template to use for your campaigns, a transactional template for your transactional needs, and an automation template to use in your automated workflows.

And with Mailjet, you can work on a new version of a template that is currently used in production, without impacting any live workflows and without having to create a duplicated version. How useful is that! No more duplicating templates when you want to make changes. You can create newer versions of a production template without impacting your users.

Template Management Gallery

All templates are stored in your Template Management gallery. The templates in your gallery are grouped by type (Marketing, Transactional or Automation).

From the Template Management Gallery, you can sort, search, create, delete, edit, export and download your templates.

And it is also where the magic happens: you can freely create newer versions of templates without affecting any currently in use…

Template Statuses: Draft vs Published

A template is either in ‘Draft’ status or in ‘Published’ status with the main difference being:

• Only Published templates are available for use when creating a marketing campaign, a transactional email, or adding to an automated workflow.
  
   
• Whereas Draft templates are not usable and can be freely edited from your template management gallery without any impact to existing workflows or users. And once your template is ready for use, you simply publish it.
  
   

The status for each template will be displayed in your template gallery….

And will be displayed next to the template name in the Email Editor.

Create a Template

You can build a template for your marketing campaigns, your transactional emails or your email automation workflows.

There are several ways you can create your own template:

• Save a template when creating your newsletter / campaign in Mailjet’s Email Editor: At any time while designing your newsletter in the Email Editor, you can save it as a template.
• Use a Predesigned Template from the Gallery – Pick a template from our inspirational gallery and easily customize it with our drag-and-drop editor. With our Email Editor, it’s easy to design beautiful responsive emails.
• Using one of Your Own Templates – Pick one of your own previously created templates as the foundation for a new template.
• Use HTML – For designers, coders or anyone who uses HTML. You can import existing HTML code to create your templates in our HTML editor, or code one from scratch.
• Use MJML Code – MJML is Mailjet’s markup language designed to reduce the pain of coding responsive emails. Import existing MJML templates directly into the Email Editor, where changes can be made by anyone.

Once you customize the template to your liking, you can save it as your own template to use in future mailings.

Using a Template from the Gallery or Your own Template

For this example, we will create a template for your marketing campaigns.

From the My marketing templates page, click on the ‘Create a new template’ button.

You can use a template from the gallery, or you can pick a template that you’ve designed before.

For this example, we will use a template from the gallery. Click on the design that you like. Then enter a name for your template and press the ‘Use this template’ button.

On the Email and Sender Details, fill out the subject and sender information. This information will be used when previewing any test emails you may send.

You can also change the default ‘Give a summary of your email to your recipients’ preview text to help increase your open rates. Just click on the ‘Customize your preview text and increase your open rates’ link and enter the new preview text. (Psst. You can change the preview text via the Email Editor at any time) ;)

Then click on ‘Save’ to continue.

Now the fun part - customizing the template with Mailjet’s Email Editor. You can easily customize the template by reordering sections, adding content, tweaking colors and much more with the Email Editor Tools.

At the top of the template, you will see the Draft status. (Remember, Draft templates are only accessible in your template management gallery, and cannot be selected when creating a new campaign newsletter).

By default, your template will auto-save every 30 seconds. But you can save your template at any time, by clicking on the drop-down and selecting ‘Save draft’.

You can also:

• Preview Your Template & Send a Test
• Save your template (as a new template or replace a current template)
• Save & Publish your Template

With HTML

From the My Marketing Templates page, press the ‘Create a new template’ button.

Then click on ‘By coding it in HTML’.

You have three choices in creating your template: import your existing HTML code, code it from scratch, or upload a ZIP file. 

• Import from File:
  Enter a template name, and then upload your .HTML file.
• Code from scratch:
  With this option, you can code from scratch as well as copy in existing HTML code.
• Upload a .zip file:
  Upload a .zip file with the HTML code and images of your newsletter. (Please ensure the main .HTML file is at the root of the zip archive, and only GIF, JPG, JPEG, and PNG images are included.)

The next step is to enter the key sender details and email information. Then you are ready to modify your template.

Once you are finished customizing your template, you can preview & test your template.

With MJML

From My Marketing Templates page, click ‘Create a new template’.

Then select ‘By coding it in MJML’.

You have two options on how to create your template: import your existing MJML code, or code it from scratch.

• Import from File:
  Enter a template name, and then upload your MJML file (with extension .MJML).
• Code from scratch:
  Simply enter a template name and continue by clicking ‘Create’.

The next step is to enter the key sender details and email information.

Before you start editing your template, please be aware there are some guidelines to follow when using MJML in Mailjet’s Email Editor.

Once you are finished customizing your template, you are ready to preview & test your template.

[top]

Preview Your Template

To preview your template on different devices, click Preview & Test → Preview email.

Test Your Template

You can also send a test email (up to 10 recipients at a time) to see how the email will appear to your clients. Please keep in mind that the look of your emails could vary between different email providers.

Click on 'Preview & Test → Send a test mail.

If you are testing your transactional template, there are two possible test options:

• Send a test email (same as sending a test campaign)
• Use the Send API

If you select the Send API test, a modal will appear showing the template version attribute that you need to add to your API call, along with sample code that you can easily copy.

Save your Template (Save As New / Replace Existing Template)

While working on your campaign or template, you can choose to save it as a new template or replace a current existing template. From the Email Editor design page, simply click on the drop-down menu and select ‘Save As’.

[top]

Save & Publish your Template

To have your template visible and usable in your gallery, your Draft template needs to be published.

Load the template into the Email Editor.

If you have publishing permissions, click the ‘Save & Publish to gallery’ button.

If you do not have publish template permissions, you will need to send a Template Publication Request by clicking 'Request publication'.

Once your template has been published, it can be used when creating a new campaign.

At any time, you can edit a published template and not affect any current campaigns or workflows.

Edit a Published Template

Once a template is Published, you can still make changes to that template via the Email Editor by saving your changes as ‘drafts’. Similar to the ‘Draft’ template status, any saved ‘draft’ changes are saved to your Template Management Gallery only, and are not available when creating a new campaign/email. Once your new version is ready, you simply publish those changes.

Let’s go through an example.

From your Template Gallery, open a published template and make your changes in the Email Editor. You will see a message under the “Published” status icon informing you that ‘You are editing the draft version. Save and publish to apply changes to your template’.

To save your new changes, click on the dropdown menu and select ‘Save draft’.

And that’s it - you have saved your changes in ‘draft’ mode!

Continue making changes to your template in the Email Editor - and don’t forget to preview & test your changes.

Once you are ready to publish those changes (and overwrite the current published template in the gallery), simply click ‘Save & Publish to gallery’...

Then agree to the confirmation window. And that’s it - you’ve successfully updated a published template.

You can view your template publication history and even choose to revert to a previously published version.

[top]

View Version History / Restore Previous Version

Any user can view the publication history for a template, including the details of any publication requests (the requestor, the approver, the user who approved/cancelled/rejected the request and their message, the date of the template status change).

There are 2 ways to view a template’s version history:

• From the template gallery:
  
• From the Email Editor, by clicking on the drop menu:
  

The Version History Page will show details of your current version and up to 5 previously published versions.

(If you are viewing a template that has never been published or has been published once, only the current edited version will be shown.)

Click on any previous version to load it onto the screen.

To restore a previous version, simply click on the ‘Restore this version’ button.

From the confirmation window, you have two restore choices:

• Restore the version directly into the Email Editor to make changes

OR

• Restore the version and publish it immediately

Please note, if your currently published version has unpublished changes, restoring a previous version will overwrite these changes.

       If you start from Transactional or Automation templates, only A sub-account is available.

5. Click Export.

📤 Exporting to a Sub-Account

If you choose to copy the templates to a sub-account, a second dropdown will appear prompting you to select the sub-account name.

• Transactional and Automation templates can only be shared to a sub-account.

Organize Your Templates with Labels

Apply meaningful labels to your templates for easier organization, sorting, and management.

For example, use labels to identify special events, holidays, seasonal templates, geographical locations, client groups and much more.

A label can be applied across all template types (Marketing, Transactional, Email Automation), and applied to as many templates as you wish.

And a template can have any number* of labels applied to it.

* Create up to 200 labels per Sub Account (or API Key). 

Create a Label

Your labels can be accessed from the template gallery by clicking on ‘Labels’ next to the search bar.

From the modal window, you can create your first label by clicking ‘Create label’.

Each label consists of a unique name, and an assigned colour. You can create your own label colour by clicking on the “+” sign.

Once ready, just click ‘Save’ to create your first label.

You are now free to create labels to your heart’s desire… which has been calculated to be 200 labels per subaccount/API key.

Manage Your Labels

From the Manage Labels window, all your existing labels are displayed in alphabetical order.

Search Labels

You can scroll through the list of labels, or type in the search field to have the most relevant results appear at the top of the list.

Edit Labels

To change a label name or label color, simply click on the ‘pencil’ icon. In the new ‘Edit label’ window, make your changes then click ‘Save’.

Delete Labels

To delete a label, click on the ‘bin’ icon, then agree to the confirmation message.

Please note, a label deletion is final and cannot be undone.

[top]

Apply & Remove Labels to a Template

From any template gallery, you can easily apply and remove labels from any template.

Click on the Options menu (gear icon), and select ‘Apply labels’.

From the modal window, scroll through the available labels, or use the search field to filter down the selection. If you select the wrong labels, just click on the ‘x’ to remove it. Once you’ve selected all the labels, then click ‘Save’.

In the List View, the applied labels will appear just under the template name.

In the Grid View, the labels will appear as a colored dot in the template thumbnail. Hover your mouse over the dots to view the full label names. If you have applied more than 2 labels to a template, the first two label dots will be visible, and the additional number of labels will be indicated by a number.

Template Publication Request

Users who cannot publish a template (or saved section) can send a publication request to anyone who has publishing rights.

Send a Publication Request

To send a publication request, simply click on ‘Request Publication’ from the template builder.

In the modal box, select a team member who can publish your template, and enter a message (optional). You can also choose to lock the template to prevent any changes from other team members while your approval request is active.

Then click ‘Send Request’ and an email notification will be sent to the selected Approver.

You, as the Approval Requester, will be notified if the template request is approved or rejected.

Please note: Only 1 active publication request per template is allowed. If a template publication request has already been made by another person, you will be notified when you click 'Request Publication'.

View All Pending Approvals

From the template galleries (marketing, transactional and automation), any templates with pending approvals will be marked with an orange dot in grid view and with a “Pending request” status in list view.

Open a template in the Email Editor, and click ‘View request’ to view the details of the request (who created the request, when it was created, etc).

Modify or Cancel a Pending Approval

The Requestor of the approval can modify or cancel the pending approval they have created

Any team member with edit rights to a template that is pending approval can edit the pending request on that template (even if they didn’t create it).

Load the template into the builder and click on ‘View request’.

• To cancel the approval request completely, click ‘Cancel request’. In the next modal, enter a reason for the cancellation (optional for the Requestor), and click ‘Cancel Request’.
  
   
  Email notifications will be sent to the Approver, and to the Requestor (only if cancelled by someone other than the Requestor).
  
   

• To edit a pending approval, click ‘Edit request’. You can then select a different Approver and edit the message. Then click ‘Edit request’ again when done.
  
   
  If a new Approver was selected, email notifications of the change will be sent to both the former and new Approver.

Approve or Reject a Publication Request

Anyone with publish permission can approve or reject a publication request, even if they are not the Approver.

Load the template in the Email Editor and click on ‘View Request’.

At this point you can either Approve & Publish the template, or Reject the request completely.

Notifications will be sent to Requestor, and to the Approver (if you are not the assigned Approver).

Using MJML in Mailjet’s Email Editor

When creating your emails with MJML in the Email Editor, please keep in mind the following constraints:

• The supported components are: mj-button, mj-column, mj-container, mj-divider, mj-image, mj-section, mj-social, mj-text
• When creating Marketing Templates, an unsubscribe link is mandatory: [[UNSUB_LINK_EN]]
• When creating Automation Templates, at least one of the following links are mandatory:
  • [[WORKFLOW_EXIT_EN]] - Allows the recipient to exit the workflow.

• [[WORKFLOW_EXIT_UNSUB_LINK_EN]] - The recipient can exit the workflow and unsubscribe from your contact list.

When you upload a MJML file in the Email Editor, you will be able to customize it using our MJML code editor but you also have the option of using our drag-and-drop tool if your MJML template has followed these rules:

• The size of the template is exactly 600px: mj-container max width = 600px
• It does not contain any section with more than 4 columns
• It does not use “mj-style”, as enabling to set style in the head part of a MJML document is currently not supported in the Email Editor.
• It only uses the following allowed components: mj-button, mj-column, mj-container, mj-divider, mj-image, mj-section, mj-social, mj-text
