Proton Mail seems to be less blackballed than most. But still has massive deliverability issues. If you want reliable delivery, you really have to stick with Microsoft, Google, AWS SES, or mayyyyybe FastMail.

I hate this situation.

I've been a protonmail user for years and I haven't seen this problem. I email to people with gmail and haven't gotten blocked, as far as I know anyway.

Same here, protonmail users for many years and never faced such issues. Overall the service has been pretty reliable and I don't really see a reason to move away from it.

The left-field approach would be to build your own client on top of an email API like mailgun or sendgrid (excluding the free tiers). But those are expensive for a personal use-case.

I've had bad luck with delivery on Mailgun, particularly to Yahoo and Hotmail/Outlook/Live.com. They have good luck reaching Gmail.

[devmunchies]

did you pay for the dedicated IP address? My delivery was good with sendgrid after I payed the $80.

[dpkirchner]

I tried to but they didn't want to assign one due to low volume (at the time). On the one hand I get it, on another I wish they were more honest about their product on its listing.

Thanks. I tried FastMail a few years back. I had delayed mail problems. Reached out to them. Their email, informing everything looked good on their end, had a 4 hour delay in the header. Heh.

[sabellito]

Do you have any data on "massive deliverability issues"? I'm a customer and knowing this would of course be very relevant to me.

For those who care: FastMail servers are located in the US
