Who is allowed to send mail as you
v=spf1 include:twilio.com._nspf.vali.email include:%{i}._ip.%{h}._ehlo.%{d}._spf.vali.email ~all
Your SPF record doesn't authorize Google to send mail. Even though FrostSender connects via Gmail, your SPF check will fail — recipients will treat your mail as suspicious.
Cryptographic signature on every send
No DKIM record found on your domain. DKIM cryptographically signs your outgoing mail so receivers can prove it really came from you. Without it, Gmail and Outlook will mark most of your mail as suspicious or send it straight to spam.
What receivers do when SPF or DKIM fail
v=DMARC1; p=reject; rua=mailto:dmarc_agg@vali.email; ruf=mailto:dmarc@twilio.com
Where your inbound mail is delivered
smtp.google.com
