How do I verify my own e-mail domain for sending?

An e-mail domain is the web address that appears in an e-mail address after the @-sign. E-mail domains allow you to set up an e-mail address using your own company name, e.g.

In order to be able to send e-mails with your email domain, a DNS adjustment is necessary.

For the following 2 entries, the combinations of numbers, spaces and special characters must be entered in your DNS settings in the exact specified order, with all contained numbers and characters.

DMARC record

Starting in February 2024, Gmail and Yahoo plan to implement new requirements for email senders. These measures are designed to better protect your contacts' inboxes from spam, while ensuring that legitimate emails get through. 

To ensure that your emails reach your recipients' inboxes and that your domain is recognised as a legitimate sender, your sender domain must comply with the new Gmail and Yahoo requirements. 

What steps are required?

To meet the latest standards for sending emails, it is essential to authenticate the DMARC record for your sender domain. We have described what the DMARC record is and what it does in this article.


We will send you the DNS entries at the beginning of the implementation process. If you have not received this or need further verification for another domain, please open a support-ticket.

Please note:

The above information refers to our standard sending provider Brevo (former Sendinblue). If you want to send via your own SMTP server instead, an individual setup is necessary.
