This is a module by Netcarver and Pete of Nifty Solutions for ProcessWire CMS that allows outbound transactional email
to be sent via the Postmark service at postmarkapp.com.
This requires PHP7.2+, a recent copy of ProcessWire 3 and a Postmark account.
Make sure you have added a verified sender signature to your Postmark account and configured your first server. You'll
need both your sender signature email address and your server's API token in order to use this module.
Install the module as usual, then insert your Postmark Server Token and Sender Signature into the module settings and
save the settings. If all goes well, you'll see the Postmark service status and the stats for your server after a few
seconds.

If you get accurate stats shown in the module configuration page, you should then be able to send emails using this
module.
