Every time I bought a new domain and need to setup DNS or verify email, all I want is to receive email from that domains. But setting up postfix or configuring lambda/ses is a pain. So I build this service.
All you have to do is point MX records to my servers and you will be able to receive incoming email.
This is the first time I have a side project that almost finished :-) after 10 years wanting to build a SaaS. To me that is a success.
