About SPF

Build it right the first time

A domain can have just one SPF record — combine every sender into a single v=spf1 line.

Each include counts toward SPF's 10-lookup limit. We track yours as you add services.

Use ~all (soft fail) while testing, then move to -all (hard fail) once you're confident.

Start with ~all (soft fail) so legitimate mail isn't rejected during setup, then switch to -all once everything passes.
