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 checked for standard email formatting rules. The system also 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.
