Just a word or advice: if you're only sending to 200 people you might not need mailgun.

You can use gsuite programmatically for easy inbox management with the Gmail API.

How is paying for G Suite and using their API instead any different?

Mainly from a user experience and customer service perspective:

You can hire a non technical person to manage your inbox without having to code as much to connect with your systems.

If you have problems with G suite, you are a paying customer and you get support from Google. There's a phone number you can call and get your problems solved.
