Email validation is the cornerstone of a strong digital marketing program. Invalid emails get your messages rejected or bounced from the inbox and hurt your sender reputation. They can also reduce the impact of your sales outreach and marketing campaigns.

Which API can I use to check the verification status of an email identity?

An API for email verification is an essential tool to help you maintain a clean and reliable database. These tools check if the email address is valid, formatted correctly and free of typos. In addition, some of them can identify disposable email addresses and other supplemental information about an email address. API email verification can also help you avoid phishing attacks and spamming by ensuring that your emails are sent to real, active email addresses.

The best email validation API tools have a robust set of features that ensure the quality of your mailing list and improve your deliverability. They can validate and verify a single email address or a list of addresses, and provide an open source SDK to simplify integration into your software. They are also compatible with a wide range of programming languages, including Java, Python, Ruby and PHP.

One of the best email validation APIs is NeverBounce, which provides a real-time API for verifying emails at the point of entry to reduce bogus registrations. It can also detect soft and hard bounces and prevent your emails from getting into the Spam Folder. It can also reduce spam complaints and increase your email delivery rate and deliverability. This service is available in both a paid and free tier and can be integrated with services like Zapier, Stripe, MailChimp and Salesforce.
