Email verification API with 99% accuracy. One API call returns complete results in under a second. Most verification tools give false confidence because they cannot handle catch-alls, Yahoo, or Microsoft 365. So emails marked “valid” still bounce. EVA fixes this with 28+ checks, deep SMTP probing, and provider-specific multi-layer logic for Google, Microsoft, Yahoo, etc., with API bypasses. Know what is truly deliverable, clean lists at scale, and protect your sender reputation.
Hey everyone 👋
If you’ve ever run cold email or managed a list, you’ve probably felt this:
You verify your emails. Everything looks “clean”.
Then campaigns go out, and your deliverability still drops.
Replies go down
Bounce rates feel off
Domains get burned
The frustrating part is this
You did everything right
Here’s what I learned the hard way
Most email verification tools give false confidence
They rely on basic SMTP checks, but modern providers do not behave honestly anymore
Yahoo accepts almost everything
Microsoft 365 can hide behind catch-all setups
Greylisting and rate limits distort results
Some servers block your IP and tools label emails as invalid
So you are not really cleaning your list
You are just getting a cleaner looking lie
That is why I built EVA
Instead of stopping at SMTP, EVA goes deeper
Provider-specific verification for Google, Microsoft, Yahoo, and others
Catch-all detection with confidence scoring, not yes or no guesses
Yahoo and Microsoft API validation to bypass SMTP limitations
28+ layered checks per email
Domain intelligence like SPF, DKIM, DMARC, blacklist, and age
Most importantly
It separates real invalid emails from server noise
Now, I want to do something different for this launch
I am offering one agency a fully set-up, self-hosted version of this system
No upfront payment
You use it on your own infrastructure
Run your real campaigns
See if it actually improves your deliverability
If it does, we can talk after
If it does not, you lose nothing
I am doing this because I want a real case study, not just claims
If you run an agency and this sounds interesting, comment here or reach out
I will pick one and set everything up personally
The insight that changed everything for me
Bad data does not just waste money
It quietly destroys deliverability
Fixing that is not about more checks
It is about the right checks
Would love to hear from you
What is the most frustrating thing you have experienced with email verification?
Where did tools fail you the most
I will be here all day, and happy to go deep technically if needed
Quick note for anyone skimming this 👇
If your campaigns are underperforming even after “cleaning” your list, the issue is likely not your copy or targeting
It is your data
Most tools cannot properly verify:
Catch-all domains
Microsoft 365 setups
Yahoo addresses
So invalid emails slip through as “valid.”
That is exactly what EVA is built to fix
Also, I am still offering the self-hosted setup for one agency
No upfront cost, I will handle the setup personally
