How to get the DKIM and SPF records?

When I tried another mailing service, they gave me SPF and DKIM records to put as TXT Records.
But where do I find these when using MIAB?
I want my mail not to be flagged as spammed

Are you using MIAB as your name servers / glue records?? Because if you are then you don’t need to do anything because it handles that for you.

If you are not look in the “External DNS” page of the admin panel.
