About Does My Email Work

Why this exists

I kept running into the same problem. One client had been sending quotes for three weeks before they realized nobody was getting them, and another couldn't figure out why their contact form submissions kept vanishing.

Every time, the root cause was the same. Every time, the email authentication was broken and the inbox providers were junking everything without telling anyone.

The tools that existed were built for email administrators, not for site owners. They'd spit out raw DNS records and expect you to know what v=spf1 include:_spf.google.com ~all means. That's not helpful if you run a bakery and just want your order confirmations to land in inboxes.

So I built this. A free scanner that checks your domain's email authentication and tells you in plain English where your domain's email setup stands.

Who built it

I'm Valentin Bora, an independent developer and email deliverability consultant. I run Mach10, a consultancy that helps businesses sort out their email infrastructure and website performance.

Most of my work has been with WordPress and WooCommerce sites, and I've lost count of how many broken SPF records and missing DKIM setups I've had to untangle.

Does My Email Work is a tool I built because I got tired of explaining the same DNS checks over and over. Now I just send people a link.

How it works

You enter your domain name. We query the same public DNS records that Gmail, Outlook, and Yahoo check when they decide whether to deliver your email or send it to spam:

• SPF (Sender Policy Framework) - which servers are allowed to send email as your domain
• DKIM (DomainKeys Identified Mail) - digital signatures that prove your emails haven't been tampered with
• DMARC (Domain-based Message Authentication) - what should happen when someone fakes your email address
• MX records - where your incoming mail is routed

Results come back in about 30 seconds. No signup, no stored data. If you want to understand why different parts of your email setup can break independently, we wrote a page explaining how email routing actually works.

Deep check (optional)

For a more thorough analysis, you can send a real test email to a unique address we generate. We inspect the actual email headers to verify that SPF and DKIM are not just configured in DNS, but actually working in practice. This catches issues that a DNS-only scan can't, like misconfigured mail servers or broken DKIM signing.

What we check

• SPF record presence and validity
• DKIM signatures across common selectors (google, default, selector1, selector2, k1, and more)
• DMARC policy and enforcement level
• MX record configuration
• DNS provider identification
• Deep check: SPF pass/fail verification, DKIM signature validation, DMARC alignment, sending infrastructure analysis
