- Record ready to copy
Your SPF record: type TXT, name @
How to use the record
Choose where you send from
Tick the services that send email on behalf of your domain: mailbox, website, newsletter.
Copy the record
The record updates as you choose: copy it in one click.
Publish and check
Add it to your DNS as a TXT record named @, replacing the old one. Then verify it with the SPF checker.
Publish it in your domain’s DNS as a TXT record named @ (the domain itself). There must be only one: if you already have one, replace it instead of adding a second.
After a few hours, make sure it’s right with the SPF checker.
Frequently asked questions
I already have an SPF record: what now?
Merge everything into one record: a domain with two SPF records fails the check.
Which include do I use for my service?
The one in your provider’s documentation: the values listed are the most common ones, but always double-check.
How many includes can I add?
The limit is 10 DNS lookups in total, including includes inside includes.
