Email validation is a tricky thing. There are a number of different ways to validate an email address and all mechanisms must conform with the best practices and provide proper validation.
Vladislav Trotsenko has developed library which solve this issue in smart way with using use MX and PTR record. Then he decided to base his own business on it. He needed to build standalone service which other companies can use for their Marketing campains.

We have helped with design and developing new service with using Go and Docker, and other languages to build API for his services, for example for Java API. In general the main idea is based on separate server which should corespond to the next requirements:

  • Lightweight

  • Platform agnostic

  • Fast integrated

As a solution we decided to develop Dockerized Ruby Rack application.
