I mostly agree.

> Workers can also send emails for free, and soon you will be able to process them as well with Email Workers.

There's got to be some limitations to that and I don't like it when they're not well defined. Looking at the MailChannels pricing, it looks like it's roughly 40x more expensive than AWS SES on the low end and 4x on the biggest plan before negotiating a custom deal.

I can send 500k emails and have a dedicated IP on SES for the same cost as 40k emails from MailChannels. Since their big value add seems to be scanning emails to prevent spam from user generated content, I just don't see it if that's not functionality you need because it's all wasted resources / unnecessary cost in those cases.

I assume there's a point where it's no longer free and I'm guessing the cost once you get there will be high.

Plus, am I sharing IPs with people who are sending such low-quality mail it requires outbound spam filtering? That seems like a huge negative on the deliverability side of things.

MailChannels is the service other services use, it's the de facto leader in combating spam. They are mostly meant to be used by high-volume hosted email services.

They are very good at detecting abuse. The leading cause of email deliverability problems is not advertisement, it's servers being hijacked by malicious actors.
