Email is still one of the most popular marketing channels. The success of your email marketing efforts largely depends on your email list. Inaccurate contact information can cost you a client, and drain time and resources.

In this article, we’re going to talk about 10 of the best email verification API services out there, and what each of these tools brings to the table.

But first, let's get to know a bit about email verification API. (or you can click here to jump straight to the list of Email Verification API Services)

What Is Email Verification API

API stands for Application Programming Interface. It’s a software mediator that lets two applications communicate with each other.

Email Verification API is an API that is specifically designed to automatically filter fake, mistyped, and non-existing emails or honest mistakes. This action requires ascertaining whether the email ends up in the inbox of an actual recipient or not, ensuring the authenticity of your email list.

The functionality of Email Verification API also includes, but is not limited to:

  • Confirming the validity of the address.
  • Ensuring that the email is recorded in their respective domains.
  • Identifying the mistyped or misspelled emails.
  • Verifying the usage of that email address.

This application prevents a ghost approach and sets a seal on an inbox to a particular email that has been in use (or not).

Do You Need An Email Verification API Service

Let’s rephrase this: Do you want to verify if all your emails sent to actual people or are they bouncing and making no impact at all?

The answer is pretty simple - Yes.

You have a list of emails of your target audience that you got when they signed your newsletter. As you did not verify them, there’s a chance that more than half of the people shared fake or non-existent email addresses, just to avoid the hassle of it.

Wrong emails won’t lead you to the wrong customers, it’ll lead you to no customers at all.

So, why do you need an email verification API service?

It opens doors of multiple possibilities, including:

Filters Valid Emails

A good email verification API service would go through all the emails that are registered and find out their authenticity, storing the authentic ones and getting rid of the rest. This makes sure you are reaching the right people all the time.

Real-time Verification

Email verification APIs offer real-time verification services so that the legitimacy of that email can be checked instantly. This is especially important for B2B email lists, as employees stop using their work email after leaving a company.

Clean Target Audience

Email verification ensures that people using fake emails are filtered out, keeping the ones who genuinely want to receive your emails. This gives you a clean email list that includes real people who are interested in your work or product.

More Delivery

When you send bulk emails from your email list, you are making sure that each one of your contacts has received that email. This results in lesser bounce rates as no email is bouncing back to you and improves email delivery.

The most important of them- it saves time and money. The emails are being delivered to actual persons on time without any bounce and you are paying exactly for that.
