Email Verification API

Email validation API description for TrueMail service. Verify individual emails as well as bulk lists.

Getting Started

You can add email validation to any part of your software with our verification API which enables you to design Custom Integrations. We give opportunities to verify either single emails and lists including thousand or millions of email addresses.

The TrueMail API is a typical RESTful API. All requests are performed through an HTTPS connection and responses are returned as JSON. This generally acknowledged configuration allows for easy use with the most well-known programming languages and development kits while remaining portable, expandable, and save.

Below you will find a description of the different endpoints, the parameters they accept, and the responses they send.

Use in the browser

The standard API is not suitable for use in client-side scripts (e.g. jQuery, Javascript). Using it on the client-side would require exposing sensitive API credentials; giving anyone access to your account.

First Steps

To begin, sign into your account and create a new Custom Integration App. Once it's done, you get to the newly created app's overview page where you can see your app's API key. You need it to authenticate your requests to our API.


If you have more questions concerning API, you can contact our support through email or in chat at the bottom of the page.
