Postmark suits developers who need to send application email through an API or SMTP and track delivery events. Its inbound processing and message streams also suit services handling both incoming and different types of outgoing email.
It suits organizations seeking to identify legitimate senders and impersonators before enforcing a DMARC policy. SPF and DKIM should be configured before enabling DMARC.
