How is the email verified?

SendBridge verifies emails through a comprehensive process of a 21+ checks to ensure the validity and deliverability of email addresses. Here's a summary of how it's done:

• Syntax Validation and Additional Checks: Every email is scrutinized for adherence to standard email formatting rules. Furthermore, the system identifies catch-all domains, detects generic role-based accounts, spots disposable email addresses from known providers, and checks for duplicates within the list.
• Domain and DNS Check: The system confirms that the email addresses are linked to valid and active domain names, ensuring the foundational integrity of the email.
• Mail Exchanger (MX) Test: This step involves checking that the email addresses have a valid mail exchanger set up, which is essential for an email address to receive messages.

These steps collectively ensure that each email address on your list is not only formatted correctly but also exists and is capable of receiving emails, thereby improving the overall health of your email marketing efforts and protecting your sender reputation.
