A Sender Policy Framework (SPF) record is a type of Domain Name Service (DNS) record that, when used, allows a third party to use your email addresses. You may use the SPF as an email authentication mechanism to allow Customer.io to send trustworthy emails on your behalf, reducing the chances of their ending up in the spam bin.
Creating an SPF Record for Customer.io
Here are the steps to set up SPF for Customer.io :
- 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 Customer.io will have the following syntax:
mydomain.com TXT v=spf1 include:customeriomail.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 Customer.io. If you do have an existing SPF record in your DNS, you need to modify it to include Customer.io, as shown below:
Previous SPF record: v=spf1 mx -all
Modified SPF record: v=spf1 mx include:customeriomail.com ~all
- Save changes
- Wait for 72 hours to allow your DNS to process the changes
