I have a Mailgun account for the website of my daughter's gym club. After they scrapped the free tier the highest Mailgun invoice was $0.98. I always found it strange, the accounting, billing costs and transaction costs must have been much, much higher. I'm pretty happy with Mailgun and don't even mind paying, but invoices less than a dollar don't make money, they cost money. Good decision on their part.
