What is email verification?

Email verification is the process of checking and confirming that an email address is valid and operational.  Email verification ensures that an email address exists and is capable of receiving emails.

How does email verification work actually?

Here’s a breakdown of how email verification tools typically work:

1. Syntax check – It ensures the email address follows the correct format, like having “@” and “.” in the right places.
2. Domain check- This verifies if the domain name (e.g., gmail.com) actually exists and is accepting email.
3. MX record check- This confirms the server responsible for receiving emails for that domain is set up correctly.
4. Catch-all check- This identifies if the email address is part of a catch-all setup, meaning any email sent to that domain gets delivered to a single inbox.
5. SMTP check- This tries sending a test email to the address and checks for a response, confirming it can receive messages.

What is an email verification tool?

An email verification tool is a software that automates the process of checking email addresses for validity and activity. It offers various features and come in different sizes and price points, catering to different needs and budgets.

There are usually 4 types of email verification services available in the market –

1. Single email checkers

These are free or paid tools that let you verify individual email addresses one at a time.

For example: Emailhippo, Zerobounce, Hunter, etc.

2. Bulk email verification tool

These tools allow you to upload and verify batches of email addresses simultaneously. They offer advanced features like syntax checks, domain checks, catch-all detection, and even SMTP checks. 

For example: Neverbounce, Kickbox, etc. 

3. Real-time email verification tool

These tools integrate with your website forms or signup processes to verify email addresses as users enter them.

For example: Briteverify, Zerobounce, etc.

4. Email verification APIs

Developers can integrate these APIs into their applications or software to verify email addresses programmatically.

For example: Verifalia, Mailgun, etc.
