I run https://hanami.run And I guanrantee you will get support from me with 10 mins during 8am-12pm PST. Outside that time I'll get to your ticket when I'm up asap. Beside forward email, we also have SMTP to send out email so you don't have to rely on gmail. If you happen to be on cloudflare try out my app https://www.cloudflare.com/apps/hanami to simplify the config steps(MX/SPF record)
Was going to suggest this alternative service but the founder beat me to it. Their support team is quite fast and helpful. Ping them on chat when I was having troubles setting up in the beginning, and they literally got back to me within a couple of minutes.
