There are two methods to validate your entire sending domain: host a temporary file on your website, or create a DNS record.
Please note, you need to have access to your website hosting or your domain registration account to validate your domain. (If you do not have an active running website for your domain, please contact our Support Team for alternate domain validation methods. We strongly advise you to have an active website behind your domain name as this will help with email deliverability.)
By adding an entire domain, all new sender addresses from that domain will be automatically verified when you add them to your account or send an email from them. If you have a pending sender address before you validate the domain, it will be validated. Please note: any previously deleted sender addresses will not be automatically verified when the domain is validated. You will need to manually add and verify the sender address again.
Validating a domain is recommended when you will be adding many sender addresses; otherwise you can verify each sending address separately. You can add up to 100 senders (sender addresses and/or sending domains) per API key.
From the Sender domain & address page, click on ‘Add Domain’.
Enter your domain name, and optional label. Click ‘Continue’.
You will now select the method of validation:
You will then see the ‘successfully validated’ screen, where you can setup your SPF & DKIM for your domain or return to your domain list.
If the domain validation was unsuccessful and you received an error message, please check the values used, specifically:
• For Option 1: Check the file name and ensure the file is empty (contains no text, no empty lines)
• For Option 2: Check the host name and values for the new TXT record

Option 1: Host a temporary file on your website
As instructed, create an empty text file and upload it (FTP) to the root directory of your website. If you do not have FTP access to your website, please contact your website host provider for assistance.
After the file is uploaded, click the ‘Check now’ button.

If you have access to your website’s DNS records, create a new TXT record with the values provided. (Contact your domain host provider for help on creating a DNS record).
Once the DNS record has been created, click the ‘Check now’ button.
