I came across one such api on mashape.com. This site is dedicated to providing a way to consume API’s. If you have never tried it, I would encourage you to go over there and check this one out. There are really no limitations and it is another way to actually verify that an email address is valid.
You have to Get an API Key (really not painful at all) and add this to your code. Here is a sample of code in vb.net that will actually return a real result. (True the email is valid, False if it is not)
You can see that I am returning the result into an object.
If you don’t know what unirest_net.dll is or you want to set up a blank project use mashape API then check out my last article.
Note: Take notice of where to enter your APIKey
