I recently was trying to contact somebody. I believed I had their correct email address, but was unable to be sure, without actually sending the email. So after some searching I found this great web tool called verify-email, that lets you check if an email address exists without sending a message.
All you do is put in the email address and click the “Verify” button. If the email address exists, you’ll get “Result: OK.” If it doesn’t, you’ll get “Result: Bad.”
If you think you know the email address, try Googling it. I found the address I was looking for, right next to the person’s name, in a PDF that was the top result on Google for that email address. That makes things much easier and more sure that its going to the correct person.
