Who is allowed to send mail as you
v=spf1 include:_spf.google.com include:helpscoutemail.com include:customeriomail.com ~all
Cryptographic signature on every send
v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCYVRGL83eMV4tMGsi33VY3dSRmOSwEev8Xod09Fcoqh3+3ICAbaOVBsciwpqF2eBOhz2/9xifIQ0NICpCXtENu7YrhDBYZ6Hd+FU087MdzFS28vybT8TKhJRcA1EMSxAA8Kjw7ELsu0YuTeQt6uXyJrsXAUSVgWo8JdPGCfVmI1QIDAQAB
What receivers do when SPF or DKIM fail
v=DMARC1; p=none; pct=100; rua=mailto:dmarc@mailshake.com; sp=none; aspf=r;
Your DMARC policy is "p=none" — monitor-only mode. Inbox providers still respect your SPF/DKIM passes, but failed mail isn't quarantined or rejected. This is fine for the first 2 weeks of a new domain, but you should tighten it once your real sends are clean.
Where your inbound mail is delivered
aspmx.l.google.com, alt3.aspmx.l.google.com, alt4.aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com
