An email checker API is a useful tool that helps businesses reduce bounce rates by ensuring that their mailing lists are free of fake and disposable emails. A good email verification API can spot duplicate emails, catch invalid domains, and even identify spam traps. By using a real-time email checker, you can ensure that your email lists are clean and that you are contacting genuine people.

The best email validation APIs offer a wide range of features that can help you verify email addresses in real time. These include syntax checks, SMTP verification, and other technologies that identify and eliminate fake email addresses from your database. Some of these tools also come with a dashboard that lets you track the number of API calls and allows you to filter them by date and other criteria. Some of the top email verification APIs also support a variety of programming languages and provide comprehensive documentation so that you can implement them into your software application.

In addition to checking the format of an email address, a good email verification API can also check if it has been compromised in any data breaches. For example, it can look for a ‘leaked’ tag in the metadata of an email to determine whether it was exposed on the dark web or not. This can help prevent unauthorized access to confidential information and protect your business from hackers.

A good email validation API should be fast, accurate, and reliable. It should be able to process large amounts of data quickly and should be scalable to meet your growth needs. It should also use 256-bit encryption for security purposes.
