The best part is that it's easy to integrate with our API, so we can quickly add new features as needed! It has been great working closely together during development of this product - they've helped us understand how users interact in their own environment (e-mail clients) which helps ensure better results when implementing changes later down stream like mobile apps or web hooks etc..
I wish there was an option where you could define your custom fields instead of having them pre defined by default but other than that everything about email check tool works well :) We are solving many problems around spam detection using machine learning models trained from data sets provided via emails sent through inboxes at work place/home addresses collected over years across various industries / geographies within India & Globally too!
