Even though many people have heard about email verifiers, or maybe used some of them, not all clearly understand the technical aspects of the service. We will show you how it works by describing the main technological features and verification steps — this will allow you to easily understand how email addresses are validated. The main Tomba email verifier features and validation steps:
Step 1 — Syntax check — this is the core feature, the first step of validation for all email verifier services. Syntax check makes it possible to check whether an email address is spelled correctly — has no spaces, commas, and all the @s, dots and domain extensions are in the right place. Step 2 — Domain check — the second step of the email verification process. Domain check allows you to be sure the domain name the email address is hosted on actually exists, is registered and working properly on the hosting domain. Step 3 — Email ping — this is the most sophisticated step of email verification. Email ping is the technical process of an email verifier service pinging the exact email address with an EHLO message, then awaiting the response from the email server. The received server-response will confirm the email address actually exists on the server and is active.
