Email Validation & Email Verification APIs

Although email usage dates back to the 1960s, it remains one of the most preferred and effective modes of communication. With many businesses making email marketing their primary means of generating traffic, improving engagement, and generating leads, the quality and validity of data have become essential for the success of marketing campaigns. According to research, up to 60% of all online visitors intentionally provide false or incorrectly typed email addresses when filling online forms or signing up to websites. This is where email validation & email verification comes in handy. But before we go any deeper, let’s understand what it entails.

What is Email Validation / Email Verification?

Email validation is a service that seeks to catch typos, whether they are misdirected or honest mistakes. This is achieved by ascertaining that the email is recorded in domains such as Yahoo, Hotmail, and Gmail. On the other hand, email verification is a more sophisticated service that seeks to confirm that an email leads to an actual recipient. It verifies whether an inbox to a particular email has been in use or not.

Email validation & email verification brings many benefits to entrepreneurs hoping to generate leads for a bootstrap startup or companies who want to be 100% sure about the quality of their email leads. Some of the boons of email validation and email verification include preventing hard bounces and helping enterprises avoid their emails being marked as spam. It also allows businesses to avoid wasting money on non-existing email leads.

What is an Email Validation / Email Verification API?

An email validation/ email verification API is a type of API that is designed to automatically detect if email addresses are valid and help get rid of those that are fake, disposable, and mistyped. It is a tool that helps companies protect their reputation by ensuring that they verify and validate email addresses before sending a message. The email validation/verification process includes:

  • Checking for invalid formats
  • Catching and correcting misspelled emails
  • Ensuring that the emails are registered in their respective domains
  • Reporting how long an email has been active and when it was used last.
    Whether you’re a developer with an app that requires registration of new users or an enterprise with a massive mail list, email validation/ email verification APIs help you to verify the validity of your email addresses, thereby allowing you to make an informed decision. Each email that runs through the validation API is categorized based on its accuracy and relevance. And if the API suspects that an email is not authentic, it isolates it and instructs you to either remove the address or correct the errors.
