Best Email Address Validation API Free In Python

Emails are one of the most effective ways to reach your customers and potential clients. But what if you send an email to a false address and no one replies? Is it possible that you are wasting time and money?
The answer is yes. According to a study by Return Path’s 2015 Email Delivery Benchmark report, the average delivery rate is just 51.6%. That means that almost half of your emails are not even reaching their destination!
There can be many reasons why this occurs, such as the recipient’s email address having been invalidated, the message blocked by the receiving ISP, etc.
The solution is to make sure you have a valid email address on your mailing list. Otherwise, you may waste time and money trying to reach people who don’t even exist.


The process of verifying that an email address is active and can accept messages is known as email validation. There are multiple approaches for validating an email address, but we will focus on two of them in this guide:

1. SMTP Verification

This approach authenticates the sending IP address and verifies that the email address exists by sending a simple SMTP (Simple Mail Transfer Protocol) command.

2. Email Address Verification API

This approach checks the format of the email address and whether it is active by attempting to deliver an email to it. It also checks whether the recipient mailbox exists, whether the recipient’s device accepts emails from your server, whether the recipient’s email address is syntactically correct, etc.
Python has become popular among data scientists and machine learning engineers due to its ease of use in quantitative tasks; in addition to its implementation in support of a variety of applications in statistics and data analysis such as pandas and scikit-learn; and machine learning such as TensorFlow.

With this in mind, we bring you a tool for email

With this API you can check if an e-mail address is valid or invalid and if it is a temporary / disposable account. If the address is valid and it isn’t a temporary email account then the “block” parameter will be false. Otherwise, it will be true.
