How to Check If an Email Address Exists

Check if email address exists helps reduce hard bounces, improve engagement rates and protect your reputation. It is an essential part of any successful email marketing campaign. However, it is challenging to verify if an email address actually exists. Traditionally, you have had to send a dummy message and wait for a response. This is time-consuming and unreliable. Thankfully, there is now an email verification API that can check if an email address exists almost instantly without sending a test message.

How can I verify an email address without sending an email?

This is one of the most reliable ways to verify an email address. People leave digital footprints all over the internet, and a simple search engine will often expose their email addresses. Of course, this method will not work on disposable or fake emails (emails that were only used once or set up to be used for a short period of time).

Another good way to check if an email address exists is through a password recovery service. Most of the major email providers like Google, Microsoft and Yahoo offer this feature. This method is quick and easy to use, but it will only reveal if an email address is valid and will not tell you whether the person who uses that email has any other associated online accounts.

The best way to check if an email address exists without sending a message is to use an SMTP (simple mail transfer protocol) email validation. This method of verification directly communicates with the email server to confirm if an email address is valid and active.
