Domain authentication will allow you to send emails for your project from an email address that you own. This can be any email address at your domain (yours, a team member, a shared/forwarded inbox etc.). This feature is useful to improve message deliverability and provide a more seamless participant experience. Currently, we only offer this feature to Research Hub subscribers.
In order to send from a domain, you’ll need to have a TXT record added to the DNS for that domain (DKIM). DKIM is an encryption key that modern mail providers use to verify that our servers are authenticated to send emails on your behalf. Adding a DKIM record to the domain's DNS will not affect any other DNS records already in place, nor affect sending from the domain/address using a method other than User Interviews.
Once we have verified that a DKIM record is in place you can set up sender profiles that send from your domain. Optionally, and for better deliverability, you may choose to set up an additional CNAME record for a custom return-path.
Follow all of these steps in order to authenticate your new domain.
Please note that DNS record changes do not take effect the instant you enter them and need to propagate through a network DNS servers. While we generally expect this propagation to take less than 20 minutes, it can take up to 48 hours in some cases. Feel free to reach out to us if you’re not sure if you’ve set the records up correctly.
