Run a free email deliverability test to see where your emails land and exactly what to fix. Send one real email and get a score, placement estimates and a prioritized fix list in about a minute.
1. Get a test address
We generate a unique address that accepts one email.
2. Send your real email
Send it from the tool and domain you normally use, with your usual content.
3. Get your report
See placement estimates, a score and exactly what to fix.
One real email, five layers of checks. Here's what your report covers.
Where your email is likely to land at each major provider, based on everything the test finds.
Yahoo84%Example values. Estimates, not guarantees: one email can't show your full sending history.
SPF, DKIM and DMARC results for the email you sent, including alignment with your From domain.
Your sending IP and domain against major blocklists. Lists we can't reach show as unchecked, never as clean.
The records behind your sending domain, from routing to reverse DNS and transport security.
A SpamAssassin score with every rule that fired, plus links, images and unsubscribe headers.
Your report scores the email out of 100. Here's what each range means and what to do next.
Great90–100
Everything checks out. Keep sending consistently and re-test after any change to your setup.
Good75–89
A solid setup with a few gaps. Work through the remaining fixes to close them.
Needs work50–74
Issues are likely hurting placement. Clear the critical and high-priority fixes before your next send.
Poor0–49
Serious problems; expect spam placement. Fix authentication and any blacklist listing first.
Calculated from the technical checks: authentication, blacklists, DNS and content. The same email always gets the same score, so you can re-test after each fix and see exactly what changed.
An analysis of your whole email and its setup that estimates where it lands at each provider and ranks the fixes. Treat placement figures as estimates, not guarantees.
A great score isn't a reputation. One email can't show your sending history, so a new domain can score 95 and still land in spam until it has built trust. Give new domains a few weeks of domain warmup first, or let the email warmup tool do it for you.
Your results list fixes in priority order. These free tools help with each one.

Poor sender reputation? Fix it with warmup.
Authentication and content are quick fixes. Reputation takes steady, positive engagement over time, which is what the Mailwarm email warmup tool builds, with a deliverability audit and an account manager for every customer.
A spam test usually means checking your content: the words, links and formatting that filters score. You can do that before sending with the email spam checker.
A deliverability test goes further. Because you send a real email, it can also check how that email was authenticated, which IP and domain it came from, whether those are blacklisted and how your DNS is set up. That's why it catches problems a content check can't, like a DKIM signature from the wrong domain.
