Pro DMARC
Supports domain-based message authentication which helps to prevent spammers from using your domain to send email without your permission.
Pro Detailed analytics
Postmark offers very detailed analytics for your emails. For starters, it stores 45 days worth of email logs where you can search to find out which emails were sent, received, who received them, who read them and who marked them as spam.
There are also recipient profiles which keep track of everyone who gets your emails, complete with a list of messages that they have opened, deleted or marked as spam.
Pro Messages are Saved for 45 Days
All outgoing messages are saved for 45 days so you can see what you're sending to who. This is important if you are sending any dynamic content in your emails.
Pro Multiple server locations
Postmark has 5 server locations around the world (3 in the US, 1 in Amsterdam and 1 in SIngapore). This way emails will be sent fast regardless of where your users are.
Pro Pay only for emails that are not opened
While other services make you pay for each email sent, Pepipost's philosophy is that email conversations should be free regardless, this way the pricing model is built around paying for emails that are not open. So it's up to you to make quality emails and make as much users as possible to open them in order to pay less.
Pro Simple APIs to send emails
Simple HTTP APIs, which are easy to understand and integrate. Complete documentation with sample code snippets for different programming languages. Refer the documentation for more details.

Inline with the philosophy, Pepipost offers deliverability and strategic consulting to clients to help them make most of their marketing investment.
Pro Awesome support

Cons
Con Expensive
Postmark are one of the most expensive (if not the most expensive) services in the market, at $1.5 per 1000 emails.
Con Bad support
They don't give attention to small businesses.
Con Slow to approve an account
It seems an option for Mandrill, but "Pepipost" is slow with support as you may have to wait a while for an account to be approved.
Con Unpredictable price
Because of Pepipost's billing plans, it's very hard to predict costs. You never know how many users will open your emails any given time and if a lot of them end up not opening them (which most of the time is true) the price can get really high.
