Things You Should Know
Postmark is for transactional email only. You may not send
newsletters, announcements to your lists or any other bulk email. If
you're uncertain if your email qualifies as 'transactional', you can
always contact support and we'll review your usage.

Similar considerations may apply to the others. If you're sending 500,000
messages at once, that does not sound "transactional" to me.

You can use a different sender address to direct individual messages
to each of the 4 providers via sender dependent relayhost settings.
No promises this will work for very long, as most likely your mail
is spam.
