Original GitHub issue: https://github.com/Sh4yy/cloudflare-email/issues/19

Since launching our free email sending API for Cloudflare Workers customers, we have been proud to provide a simple yet effective solution to deliver messages from Workers code with a minimum of setup complexity. Unfortunately, we regret to announce that this free service will be coming to an end on June 30th, 2024.

What's next?
Cloudflare customers utilizing the free MailChannels email API have until 5:00 PM Pacific Daylight Savings Time (UTC-7) on June 30th, 2024 to transition to an alternative email delivery solution. After that date, the API endpoint will begin rejecting connections from unauthorized senders. As soon as June 1st, 2024, we will begin failing a small fraction of API requests and including a link to this article in the error message.

Found this repo for the first time today, was excited to use it, didn't think this journey would end before it even started :(

RIP

Author should put a warning on the readme or deprecate this repo. Everyone who looks at this repo will be like me or the others experimenting with it and failing or looking into the source and realizing it's using mailchannels and reading from elsewhere that mailchannels is deprecated.

This is some sort of honeypot time suck for everyone who reads this repo. But ofc, appreciate the OP for sharing the code originally and even now, but imo it's time to deprecate this or put a big warning to others not to use this.

@Sh4yy https://github.com/Sh4yy/cloudflare-email/pull/23

I added a prominent warning to the readme that links to the deprecation notice.

Well that's out the window. Gonna have to go shopping, MailChannels has 100 free messages a day. The Gmail SMTP trick gives you 500 and takes hooks.
