I recently switched an old PHP project from sending me emails directly via SMTP to using mailgun. At first I tried to use their SDK. It pulled in like a dozen dependencies. I gave up on that idea and replaced it with a simple curl call.

I had very similar experience with npm. Especially when you need to merge all the security updates for the sdk and all their dependencies. I also prefer interacting with the api, if it is straightforward.
