I have been writing to the support for over a month to check why the emails are not getting validated properly. Because even after I get the emails validated here, so many emails keep bouncing 1% is okay for me. Every time it is 7 to 8% which is killing my inbox.

The only response I get from support chat is that they have sent it to the team to review. No response. Very poor email validation system and very poor customer support.

Single emails anybody can do it even via excel sheet. The idea is to use this to validate bulk emails but bulk email validation is poor and it is killing my inbox.
