Prevent bounced emails and low-quality users with 100 FREE professional grade email verifications every day
Need more?
Note: The speed of each verification is dependent on the speed of the mail server.
Slow servers will always result in slow verifications.

API Usage

Using the free email verification API endpoint is pretty straightforward. All you need to do is perform a GET request on the main lookup endpoint using the following schema.

https://api.trumail.io/v1/{format}/{email}
Currently there are three formats supported: json , jsonp (using a "callback" (all lowercase) queryparam) and xml .

What it does

Trumail is a fast and accurate email address verification API written entirely in Go. It was built with the intention of providing software engineers and businesses with a simple and easy to use solution to bounced emails.

Whether you're a developer writing an application that requires the registration of new valid users or a business with a large mailing list, Trumail can handle the heavy lifting of verifying the validity of your email addresses so that you can make a confident decision on whether or not to dispatch messages to a given address.

We currently provide a real-time lookup API which allows you to make an instant informed decision on user validity. In the near future we hope to have Bulk Lookups fully implemented.

Privacy Policy

To protect you and your users contact information, we DO NOT store or share any lookup data on our own servers unless otherwise specified. Trumail is a basic API service and we therefore have no database to store data in. All that is currently collected are request logs in order to debug issues with the API, all of which are pruned every 1,500 messages (according to Herokus documentation).
