ImprovMX mail catch and forward service

Hi,

I am looking for a way to forward mails from [foo@bar.com](mailto:foo@bar.com) to [foo@bar.xyz](mailto:foo@bar.xyz) populating MX records . Some registrars offer mail forwarding options out of the box, my current one doesn't. I came across https://improvmx.com/, which sounds good, but somehow too good to be true. There is no information whatsoever who is behind that website, and why they provide their service for FREE. Any thoughts? Would you trust such a service? I'm a bit skeptical. I'm pretty sure it will work just fine, but I always feel like there has to be a catch if something which costs money to maintain is offered for free.

Thanks!
