How To Create Email Validation Service With NodeJS

mailboxlayer by apilayer is one of the market-leading email validation and verification APIs. With mailboxlayer, you can easily separate low-quality email addresses in your mailing lists from your real users. 

Why is this important? It’s pretty simple really. As a marketer, you spend time creating and maintaining an ever-growing email database. If you regularly send emails to bad or incorrect email addresses, however, you could run into trouble. ISPs monitor email senders and high bounce rates result in a lower email score.  When that happens, ISPs will begin treating your email address as Spam and all your emails will start going to your recipient’s Spam folder. As you can imagine, this is a disaster if you are trying to connect with your customers.

To solve this issue, you can rely on mailboxlayer API. With the mailboxlayer API, you can:

  • Reduce your bounce rates
