Overview
Email verification is a key factor in maintaining high email deliverability.
What is Email Verification
Email verification is the process of confirming that an email address is:
Valid in format
Connected to a working mail server
Capable of receiving emails
What Does This Involve
Functional Mail Server (MX Record):
Ensures the domain has a valid mail server that can receive emails.
Active Mailbox Check:
Verifies that the specific email address is active and not closed or suspended. This is usually done without sending an actual email, often via a server ping.
Why Email Verification Matters
Reduces Bounce Rates:
Sending emails to invalid addresses leads to bounces, which can harm your sender reputation.
Improves Deliverability:
A clean email list increases the chances of your emails being delivered, opened, and acted upon.
