When I send the email via the API it seems to use one of the built-in templates and prepends [McNeel Forum] [PM] to the subject. While reasonable for other uses of PMs, I’m concerned that our users who are not on the forum will find this confusing or even spammy.
Is there a way to specify a custom template when sending via the API? I don’t see it here:
You can customize the text of that Customize text in Discourse but not different for api and front end. If you need it different, you’ll need a plugin.
