Desktop Bulk Email Verification application
I've been working on a desktop app called MetaLogic Bulk Email Verifier and I'd genuinely love to get some feedback before launch.
The idea started because most email verifiers I tested were either:
web-based and expensive,
privacy-unfriendly,
subscription-heavy,
or painfully slow with large lists.
So I decided to build a desktop-first alternative focused on speed, privacy, and handling large email lists more comfortably.
Current features include:
Bulk email verification
SMTP + MX validation
Proxy support & rotation
Pause / resume verification
Local processing (no uploading email lists to servers)
Detailed export & filtering
Windows + macOS support
One thing I focused heavily on is privacy. Everything is processed locally on the user's machine.
The app is not launched yet and I don't even have a download page ready yet — I'm still polishing things and trying to understand whether people actually find this useful.
So I'd really appreciate honest feedback:
Does this sound useful to you?
What features would you expect from an email verifier?
What frustrates you most about existing tools?
Would you prefer one-time purchase or subscription for something like this?
I'd love to hear your thoughts
