How To Create Email Validation Service Using MailboxLayer API with NodeJS

The accuracy and legitimacy of email addresses are highly important for effective communication, be it for personal or business purposes. 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 invalid addresses, 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. By using Node.js and the mailboxlayer API, developers can create a solution which can be used to verify email addresses. This email address validation API will help improve email deliverability and safeguard against undeliverable emails. This article explores the process of creating an email validation service, exploring the email verification process and the tools needed to execute it effectively.

How to Find a Good Email Validation Service

When selecting an Email Validation Service, several key features should be considered to guarantee the best performance. 

  • Firstly, the service must effectively identify invalid email addresses. This will help validate email addresses from various email service providers. It will also eliminate the risk of bounced emails and safeguard the sender’s reputation.
  • It must be capable of handling bulk email verification efficiently while maintaining accuracy. 
  • It should be able to smoothly integrate with existing systems, whether through direct integration or APIs. This will improve usability. 
  • It must be a service which offers email verification tools, including detection of disposable emails and high-risk addresses, along with syntax checking and domain validation.
  • The service should include user-friendly interfaces and flexible pricing options, such as pay-as-you-go or monthly subscriptions, to contribute to a positive user experience. 

Among the top solutions, mailboxLayer API stands out for its reliability, scalability, extensive features and reliable email validation process. The above reasons make it an ideal choice for businesses looking to improve email deliverability and improve marketing campaigns.

How to Do Bulk Mail Checks?
