Sometimes timing out after 3 minutes

[Powersource]

Still investigating this issue so not clear on all the details but this seems to happen >50% of the time but not 100%. Here's one of our logged failed requests (newlines arbitrarily entered to make it easier to read)

The code that does the sending https://github.com/cobudget/cobudget/blob/7e07ee91ffd67129462851fd49637e2841951601/ui/server/send-email.ts#L41-L48

We noticed this on magic link log-in emails so very low volume

We're running 2.9.0, the newer releases seem to have different error handling so I guess I'll try updating.

Hi @Powersource

are you still see this issue? We haven't received this type of timeout notifications from any other users, and haven't seen it before. Have you try to run the code in different environment, on different network?

It seems to be network related issue.

Also I see you use pretty large batches there, of 500 emails, which can easily get to be pretty big email sends. We also recommend trying out smaller batches, of 100 emails for example. They will ease up the load on your network, and Postmark will also handle them easier.
