If your email keeps landing in spam, it's almost always because SPF, DKIM or DMARC are missing or misconfigured. eSMS Mail sets these up when you verify a domain, and gives you tools to check any domain and generate the records to paste.

Run the audit

The Deliverability page scores any domain's SPF, DKIM, DMARC and MX and gives it a grade (A–F) with a concrete fix for each problem. Run it on your domain — and on your competitors'.

Generate the records

Get ready-to-paste DMARC, SPF and BIMI records:

  • DMARC — start at p=none to monitor, then move to p=quarantine and p=reject once your reports are clean.
  • SPF — authorises eSMS Mail to send for you.
  • BIMI — shows your logo next to your emails in Gmail/Apple Mail (needs DMARC enforced + an SVG logo, and a VMC for Gmail).

The short version

  1. Verify your domain (DKIM + SPF are handled for you).
  2. Add DMARC — monitor, then enforce.
  3. Re-run the audit after any DNS change.

This is the same authentication stack the big senders use. No one can guarantee the inbox, but getting SPF/DKIM/DMARC right is what puts you there.
