How do I add multiple SPF records?

Having multiple SPF records on your domain is not recommended as it will cause any SPF authentication to fail.

Before adding an SPF record, please check if there is already one set up for your domain. If an SPF record is present, you can merge the original record and the new one you wish to create.

Please note: if you are using a Generation 2 mailbox, please use the following SPF record: v=spf1 include:secureserver.net -all

If you are using a Generation 1 mailbox, then you should use the following SPF record: v=spf1 mx a include:spf.123-reg.co.uk -all

How do I merge multiple SPF records?

If, for example, you have the following record for your domain: v=spf1 mx a include:_spf.google.com ip4:51.163.70.200 -all

And you need to add a new record, such as: v=spf1 include:secureserver.net -all

Then they can be merged into the following:

v=spf1 include:secureserver.net include:_spf.google.com ip4:51.163.70.200 -all

The newly created SPF record sets a policy for your domain, telling mail servers across the Internet that emails sent from the addresses associated with your domain should only be accepted if these have been relayed using the 123 Reg and Google mail servers.
