Connecting a Custom Domain (Subdomain) for Sending Emails

If you want your emails to be sent on behalf of your domain — this is possible. You need to connect a domain or subdomain to our mailing system to do this.

1. Provide us with your domain or subdomain

In the first stage, you must inform our support team of the domain or subdomain from which you plan to send emails (for example, mail.yourdomain.com).

⚠️ Important: If your primary domain (yourdomain.com) is already being used for your corporate email (e.g., via Gmail, Outlook, etc.), we do not recommend using it for sending emails through our system, as you will not be able to receive emails. In this case, creating a separate subdomain (e.g., email.yourdomain.com) specifically for mailing purposes is better. This will help avoid conflicts and ensure the main email remains fully functional.

2. NS Records

Once you provide us with your domain (or subdomain), we will generate the necessary set of NS records (Name Server).

These records ensure the correct configuration of your domain for email delivery, including important security and authorization parameters (SPF, DKIM, DMARC), which affect email deliverability.

You will need to log into your domain registrar’s control panel and add the provided NS records.
These records will route the management of the subdomain to our email service.

If you are unsure how to do this, please contact your registrar’s support team.
After adding the records, the changes may take some time (from a few minutes to 24 hours) to take effect.

3. Domain Activation

Once we verify that the settings are correct, we will activate your domain (or subdomain) in our system, and you can send emails on its behalf.

We recommend using a subdomain — this is the optimal and safest method for organizing mailings without affecting the operation of your business’s primary email.
