About OutboundAuth

OutboundAuth is a free email deliverability toolkit. It checks your SPF, DKIM and DMARC setup, builds the records for you, and explains what to fix — in plain English.

Why this site exists

Good emails land in spam every day, and most senders never find out why. Authentication records — SPF, DKIM, DMARC — decide whether mailbox providers trust your mail, but they're written in DNS syntax that reads like a foreign language. OutboundAuth exists to close that gap: run a check, get a straight answer, fix the problem.

What you get for free

Everything in the toolkit is free to use, no account needed:

  • Health check — grades your domain's SPF, DKIM and DMARC in one pass.
  • Record builders — generates correct SPF and DMARC records for your setup.
  • Header analyzer — reads authentication results from real message headers.
  • Guides — plain-English explainers on SPF, DKIM, DMARC, spam causes, warmup and more.

Who runs it

OutboundAuth is built and run by Saqib Naseer Khan, an email deliverability specialist. Alongside the free tools, he offers paid one-time audits, full authentication setups, and ongoing monitoring for businesses that would rather hand the whole thing over — see Services.
