Making an Android to SMS to SMTP App in a few hours.

During a meeting I was only half needed in, I ended up spinning up a small Android app for sending SMS to email over SMTP mostly with Gemini 3.

That worked for a while, then Gemini 3 Pro started going into full meltdown mode and taking Visual Studio Code down with it. At that point I switched to Codex 5.3 on Extra High and used that to finish the job.

The problem

I wanted a cheap way to get OTPs into email without paying for yet another subscription service.

The setup I had in mind was simple enough:

  1. stick an Android phone in the office

  2. let it receive SMS

  3. forward those messages to an email address over plain old SMTP

  4. send that into a Google Group so the right people can see it

That’s it.

No platform. No monthly fee. No credit card and lock-in.
SMS in, email out.

It’s open source.

Get it on Github.
