Swoosh - email client to compose, deliver and test your emails easily in Elixir

Grats on the release.

Swoosh 1.4 released with a built-in Finch-based API client. (it has always had a hackney-based one)

Now you can pick either hackney or finch.

If you implement a custom API client, you can use anything else

Neat! I saw it the other day but I saw it was hardcoded to Swoosh.Finch, wasn’t aware that I can switch it.

By the way slightly unrelated, are we typically meant to start a new Finch instance for every endpoint we connect to for the performance?

Not really. A Finch instance can handle multiple pools. Unless message passing is becoming the bottleneck (not likely), you shouldn’t have to start multiple of them.

From Finch documentation:

  {Finch,
   name: MyConfiguredFinch,
   pools: %{
     :default => [size: 10],
     "https://hex.pm" => [size: 32, count: 8]
   }}

Thanks I missed that out in the documentation, I thought there is only one pool per instance but looks like Finch can start multiple per host, that’s awesome!

Great work!

1.5 released with Telemetry support.

1.6 released a few days ago.

Features

add OhMySMTP adapter @taobojlen (#663)

And a ton of documentation updates.

Hello everyone, I opened a new PR on Swoosh for a new adapter for self-hosted Mailpit servers. Mailpit is great, because it includes compatibility checks. I’ve been using it for almost 2 years.
