Questions and answers

Where do I add the SPF record?

At your DNS provider (Namecheap, GoDaddy, Cloudflare and so on): add a TXT record with host @ and the record as the value. Remove any older SPF record first; a domain may have only one.

What does the counter mean?

Receivers follow at most 10 DNS lookups when reading SPF. Each include counts. Above 10, SPF fails.

~all or -all?

Start with ~all. Move to -all once you are sure every service you send from is listed.
