These are email marketing platforms, not bulk transaction email platforms, and I don't see why they can't do with the latter. At a bulk transaction platform, such a tiny amount would cost at most $20-$50/mo. If you're willing to do a bit of work to use AWS SES, that would be $2-$5 a month. Azure ACS would be even cheaper.
How much does it cost if you make your SMTP server connect to their SMTP servers and exchange mail?
Every bulk transactional email provider I could find* allows SMTP relay even in the basic/free plans. That feature seems to come for free everywhere.
* e.g. SendGrid, Postmark, mailjet, mailgun, mailerroo, etc.
