Email is still the most widely accepted way to connect with people that matter to your business. Unfortunately, their proliferation makes it difficult to separate professional email addresses from personal or spam mail. API-based email verification services solve this problem. Hunter provides a fast and accurate API that serves as a complete email checker. In this post, we explore the features of Hunter email verifier API and compare it against five other popular email verification and validation APIs.

What to Look for in Email Verifier APIs

If you are seriously exploring an email verifier API for your business, chances are that you are facing the problem of too many invalid email addresses getting into your system. This situation happens through various lead generation channels or customer interaction channels. In such cases, you do not have any control over what data is being submitted by the user.

An email verifier API is a perfect way to address this challenge. Firstly, it serves as a complete email checker without adding any burden to your website. Moreover, APIs provide a standard interface to validate verification requests which can be seamlessly integrated with any web application. In this way, the verification process happens on the fly and invalid email addresses are filtered out at the point of data entry.

We have analyzed all the email verifier APIs based on a few important parameters which are relevant for business users collecting email addresses as part of their lead generation forms. These parameters are:

  • Email Address Validation: The email address validation feature checks the email address for basic format and identifies catch-all emails or role-based email ids.
  • Email Service Verification: The email service verification feature checks for domain information about the email address. It also verifies the SMTP domain search service and MX records pertaining to the email addresses.
  • Free Tier Access: Free tier access allows you to try the API for free up to a certain limit of API calls. This helps you understand whether the API is suitable for your business or not.
  • Pricing: The pricing structure of the API service helps you gauge your expenses based on availing the API service for your business.
  • Email Quality Score: The email quality score is an internally calculated probability score about the deliverability status of the email address. Most email verification services provide this score as an objective means of segregating genuine email addresses from fake.
