I want to check if the mail id exists or not. I tried smtp/helo to the server, but it is not 100% accurate. I want 100% accuracy so the best solution I check online is to send mail to a person, which I am fine with it, but there is one problem: my IP will be blacklisted. Is there any way to send an email without my IP being blacklisted?
I think that if I connect to a VPN and send an email, my IP address will not be blacklisted.
At least I want to verify 200 mail per day
Please share any thoughts you have.
