ImprovMX vs. Mailgun

Mailgun offers a suite of email products with a focus on email sending and tracking, with email forwarding as a side feature. ImprovMX focuses on a first-class email forwarding experience with better pricing, friendlier support, and a simpler product surface area.

You'd generally pick Mailgun if you prefer a more enterprise offering or need advanced email sending. And you'd prefer ImprovMX if you want a smaller more customer-focused company with a simpler experience focused around forwarding.
