Check if email exists is an essential part of any e-marketing campaign. It ensures that your emails reach the inbox and avoid getting marked as spam or even being blocked by email service providers. It also saves you time, money and effort on crafting campaigns that end up in the trash. But what happens if you skip this step? You risk losing your audience and damaging your reputation.

Invalid email addresses have several causes. They could be due to syntax errors or they might not exist on the email server. In addition, they may be catch-all addresses that are not monitored and can be used by anyone. These issues are a big reason why you should check if an email exists before sending out any emails.

Check if Email Exists: Verification Techniques

To make sure that an email address is valid, you can use some simple tactics. One method is to send a test email to the address and see what happens. However, this is not a practical way to check for all email addresses in a large list. This is because email services typically deliver messages to a mailbox based on the MX records that are associated with the domain name. Those MX records are a roadmap that specifies which servers are responsible for accepting email for a particular domain. If the MX records do not point to a reputable mail server or if they are nonexistent, that is a red flag.

Using an email validation tool is a more efficient way to check if an email address exists. These tools can verify an entire list of email addresses in a few minutes or less. They can check for syntax errors and confirm that the email account is active on the server. Most of these tools will also look for catch-all addresses and spam traps that are used by email service providers to identify and block malicious senders.
