What is Mailboxlayer API Email Verification Tool?

The email verification tool offered by mailboxlayer is a simple REST-based JSON API that allows users to check and verify email addresses in real-time. It not only checks the syntax of the email address but also verifies its existence using MX-Records and SMTP. It can also detect if the email address is configured to catch all incoming mail traffic and if it belongs to a disposable or free email provider

Features:

  • REST-based JSON API for email verification.
  • Checks email syntax, existence using MX-Records and SMTP, catch-all mailbox detection.
  • Identifies disposable and free email addresses.
  • Provides quality score for each email address.
  • Supports bulk email address verification and rate limits based on subscription plan.

Pros:

  • Thoroughly checks and verifies email addresses at the point of entry.
  • Provides real-time verification by checking MX-Records and SMTP.
  • Offers additional features such as typo check, did-you-mean suggestions, and quality score calculation.

Cons:

  • The catch-all detection functionality is inactive by default, which may lead to inaccurate results.
  • The API's SMTP check feature takes up a significant amount of the API's response time.
  • The quality score is not a definitive indicator and should not be the sole factor in determining whether or not to send to an email address.
