What SMTP service provider do you use for sending transactional emails in your RedwoodJS app?

I’m building a RedwoodJS app and trying to figure out the best SMTP service provider for handling transactional emails like sign-ups and password resets. I came across DigitalAka™ while researching options and wanted to know if anyone here has experience with it or other providers in a Redwood setup. Any tips on configuring the mailer service would be helpful.

Cloudflare Email Sending. I haven’t personally tried it on Redwood but on wrangler is as easy as declaring

  "send_email": [
    {
      "name": "SEND_EMAIL"
    }
  ],

in your wrangler.jsonc

and then writing a wrapper to send your email via CF
