How an Email Verifier Works: Step-by-Step Guide

Last updated: 27 December 2024 в 07:03
Email verification tools ensure your lists go through checks such as syntax, domain, catch-all, MX record, and email address ping. This is a simplified explanation; in reality, verification algorithms are complex, multi-step, and involve various methods that directly or indirectly, and in combination, determine the most accurate email verification results.
For Example:
  • Syntax - a simple check to ensure the email address conforms to common standards.
  • Domain - a lookup on the domain element of the email address to ensure it is configured to accept emails.
  • SMTP check - the really clever bit, where we check that the user mailbox exists. By checking with a would-be recipient’s email server via SMTP, we can often see whether a user for a given email address actually exists.

Important:
We do not physically send emails, so email verification is a safe process for your recipients.
There are several ways to verify your email database.
It’s simple—create an account and select one of the following options:
1

Bulk Email Verification

Verify your email lists using the Proofy web interface:
  • Upload your email lists via the web interface.
  • Click “Proof” and wait for the process to complete.
  • Download the verification results as valid or custom presets once finished.
2

API Email Verification

Set up secure email verification by directly connecting to your email database from your service or server:
  • Upload your email lists via the web interface.
  • API verification is fast and secure but requires technical expertise to integrate the code into your server.
  • For setup details, refer to the Proofy API Docs.

  • Embed the widget code into your website using our detailed documentation.
