What does email verification do?

Email verification certifies that the email addresses you are sending to are active and can receive emails. At its core email verification providers tell you if an email address is real and connected to a real person and they use various techniques to do so:

​​1. Syntax validation: This technique ensures that the email address follows the correct format and syntax. It checks for any missing or invalid characters, spaces, or special characters.

2. Domain name system (DNS) validation: This technique verifies that the domain name in the email address is valid and exists. It checks for issues such as invalid or expired domains, subdomains, and email servers.

3. Mailbox verification: This technique checks if the email address is actually receiving emails. It sends a test email to the email address and then checks if it is delivered or not.

4. Role-based email detection: This technique identifies and flags email addresses that are associated with a role or a group of people, such as "" or "". These types of emails are often less likely to be engaged with or read by a real person.

5. Disposable email address detection: This technique identifies and flags email addresses that are temporary, one-time use, or are commonly used for spam. This helps businesses avoid sending messages to addresses that are not likely to result in meaningful engagement.

Email verification is a crucial component of email marketing. It ensures that your messages are reaching valid and authentic email addresses and increases the effectiveness of your email marketing campaigns. By understanding email verification and using a reliable email verification service, businesses can maintain their sender reputation and maximize the potential of their email marketing efforts.
