Email verification API overview is a critical tool in the digital toolkit of marketers, developers, and businesses looking to ensure effective communication channels. Email validation helps reduce bounce rates, clean up contact lists, and improve inbox placement by removing bad submissions like spam traps, honeypots, and fake/defunct email addresses.

Use our real-time API to perform on demand validations of user input at the point of entry. Surface validators to users during form completion, or incorporate them into your backend systems to prevent bad submissions from entering your database in the first place.

Email Verification API Overview: Reduce Bounce Rates

Our email verification tools inspect email addresses to ensure they conform to IETF standards and that they can be linked to mailboxes and mail servers. We also check for common disposable email services that allow fraudsters to spawn new emails at will, and help ensure your contact list is free of them.

You’ll need a Pro or Premier level account to access our Email Verification API. To get started, create a new API key with the Email Address Validation Access permission (found in your Portal credentials). You’ll need this API key to call the Email Verification API endpoints. For your security, it’s recommended to keep this key private and only share it with trusted developers in your organization.
