How to Set Up SPF for Customer.io?
SPF records are used to help prevent email spoofing. They help to ensure that only authorized servers can send emails on behalf of your domain. SPF records can help to improve your email deliverability.
How to Configure SPF for Customer.io
- Sign in to your DNS administration interface.
- Select DNS Template under Tools & Settings
- You must change the DNS TXT record for SPF.
- For Customer.io, an SPF TXT record will have the following syntax:
mydomain.com TXT v=spf1 include:customeriomail.com ~all
- This record should be published in the DNS records section for the relevant domain.
Worth noting: To activate SPF for outgoing emails using Customer.io if your domain previously lacked an SPF record, all you need to do is publish the aforementioned record. If your DNS already contains an SPF record, you must update 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 adjustments.
- Allow your DNS to process the adjustments for 72 hours.
