Our email validation service via API calls checks:

• Syntax

  Check if the email address conforms to the IETF standards by using a complete syntactic email validation engine.

• If the address is branded

  Check if the address is custom and linked to a business email account or if it is generic and coming from a free email service.

• If the address is disposable

  Check if the email address is supplied by a known disposable email address provider such as Mailinator, 10MinuteMail, GuerrillaMail, and 2,000+ more.

• Mail server existence

  Check for the availability of email addresses’ corresponding domains by ensuring the existence of DNS MX records.

• Mailbox existence

  Check if the email address exists and can receive emails via the Simple Mail Transfer Protocol (SMTP) through email-sending emulation techniques.

• Use as a catch-all email address

  Check if the email address can receive emails for more than one email address.
