API email verification is the process of ensuring that an email address is valid and in use. This is important for marketers, sales teams, and customer service representatives because when bad data gets into your system, the lines of communication break down and your brand suffers.

The best email validation API tools are simple to integrate into your application and provide real-time verification, which ensures that the email addresses in your database are valid and active. These services will also help you avoid the costs associated with poor sender reputation scores. Poor sender reputation scores are a direct result of sending emails to inactive or invalid addresses, which results in the email being marked as SPAM and sent to the user’s junk folder or even rejected completely.

Using a verification API to filter out the bad email addresses helps you maintain a good sender reputation and maximize your inbox placement rates. These services can also reduce the number of bogus signups and help you acquire better-quality leads and subscribers.
