Free Email Verifier - The first free and accurate email verification service

Our email verification service validates your addresses before you send to your list. Email addresses are tested for syntax and accounts are tested for validity in real-time over SMTP. We also use AI to figure out first names from just email addresses.

Nice but I checked some mails the system said "blocked" what is it?

@yusuf_bayram https://www.gmass.co/blog/email-... "...This includes addresses where the status is Valid, Blocked, or Unknown. It might seem counterintuitive that we include in your final send list an address that is BLOCKING email from us, but an address that is BLOCKING email from us is an indication that the address is good. Also, the address might be blocking email from our email verification server, which is hosted at Amazon Web Services (AWS), but that doesn’t mean that it will block email sent from your Gmail account or a third party system like SendGrid. That is why if the verifier detects a block, GMass will still attempt to send your email to that address."
