Email validation API

An email validation API is a specific API offered by some ESPs like Mailgun, that automatically checks your email list for errors, common typos, domains, etc. to validate your email addresses and ensure your email list is clean. This contributes to a healthy sender reputation.

Email address verification should be an integral part of email workflow, as invalid email addresses or “low-quality” emails like info@ or admin@ addresses lead to soft bounces and negatively impact deliverability.
