EV3 – Operations

List of Operations

• ValidateEmailAddress  (Recommended Operation)
  • Validates and verifies an email address via a full suite of tests and real-time SMTP checks. This operation performs real-time server-to-server verification via SMTP communication. This operation allows the user to specify a timeout value, in milliseconds, for how long it can take to perform SMTP level checks. A minimum of 200 milliseconds is required to perform these checks. However, results are dependent on the network speed of an email’s host, which may require several seconds to verify. Average mail server response times are approximately between 2-3 seconds, but some slower mail servers may take 15 seconds or more to verify. 

• ValidateEmailFull
  • Corrects, validates and verifies an email address via a full suite of tests and real-time SMTP checks. Since this operation performs real-time verification via SMTP communication the response time is dependent on the network speed of an email’s host and may take several seconds. The average response time for this operation is approximately 2 seconds, but the operation can take as long as 10 seconds.

• ValidateEmailFast
  • This operation has the same inputs and outputs as ValidateEmailFull. This check will not perform any real-time SMTP level checks, however it may still provide SMTP level information via one of our other mechanisms.

• ValidateEmailFullNoCorrections
  • The same as ValidateEmailFull but the service will not attempt to correct the email address.

• ValidateEmailFastNoCorrections
  • The same as ValidateEmailFast but the service will not attempt to correct the email address.
