SPF records tell the receiving mail servers which sending sources are allowed to send emails on behalf of your domain. If a server is successfully checked, it means that the one sending the email is verified and not spam. You need to add an SPF record for Trustpilot in order to identify it as an approved email source for your domain.
Creating an SPF Record for Trustpilot
Here are the steps to set up SPF for Trustpilot :
Login to your DNS management console
Navigate to Tools & Settings > DNS Template
You need to edit the DNS TXT record related to SPF
An SPF TXT record for Trustpilot will have the following syntax:
mydomain.com TXT v=spf1 v=spf1 include:trustpilotservice.com ~all
Publish this record in your DNS records section for your respective domain.
Note: If you don’t have an SPF record previously for your domain, simply publish the above-mentioned record to enable SPF for outgoing emails using Trustpilot. If you do have an existing SPF record in your DNS, you need to modify it to include Trustpilot, as shown below:
Previous SPF record: v=spf1 mx -all
Modified SPF record: v=spf1 mx include:trustpilotservice.com ~all
Wait for 72 hours to allow your DNS to process the changes
