The thing about selfhosting email is that, Even after getting rated 10/10 in every mailchecker service and after a nearly 1 year service, Gmail still marks it as spam. So Gmail is basically the monopoly that undermines small startup business by marking their Email service as spam. But ofc this will happen because Europe allows it, making Europe lawmakers an inferior entity even to a private company.
Is it from sending mass emails that look like spamming? I've never had a problem sending to Gmail but my personal server is only used by me and a few others for personal email.
We communicate via email exclusively with our already users and clients which in 99% of the cases contact us first (from same gmail address that mark our service as a spam), we don't have time to spam which anyway will damage our reputation. The funny thing is that, All this happens mostly with traffic in our own continent in our own country (we are not even trying to get intercontinental clients)!
