I've started recommending my clients Postmark after trying a lot of email providers. Postmark is a small company yet one of the best in the transactional email world! The setup process, stats for emails and user interface are minimal yet do a great job. It has plugins for WordPress which uses API to send emails rather than SMTP connections. This is a better way to send emails because, SMTP uses a synchronous connection and REST API is an Async. This way they are able to deliver super fast email service. Most of the transactional emails like order information, login details, contact us messages and most day to day messages go through the postmark service. They also offers credits for bootstrapped start-ups. Review collected by and hosted on G2.com.

Customer support is great but not the best! They take time to respond like 24 hours or so. I wish they had a 24 hours service. Also pricing is a bit premium but well worth the price and the smooth service they offer. Review collected by and hosted on G2.com.

It's a great SMTP provider that is easy to setup as well as great delivery and clean IPs on top of that postmark also has a DMARC reporting tool which I like and recommend to any begginer or non-techy person out there. Support is great and quick to reply to any issues you might have. Review collected by and hosted on G2.com.

There isn't something I dislike tbh, the tool is stable and everything you need to be on the same pair with Sendgrid, Mandrill and similar Review collected by and hosted on G2.com.

Email delivery and trust with our customers is our first priority at www.TruckX.com, so Postmark is our go-to for Email APIs because automated emails can be created and managed smoothly. Review collected by and hosted on G2.com.

Their analytics could be even more detailed in examining how the data performs. Review collected by and hosted on G2.com.

Postmark has come to change the way we send confirmation and transactional emails to our users. Purchase confirmation emails, user activation, and purchase reminders (you name them) ended up in the spam section, bounced or in the promotional folder of our clients. Thanks to Postmark, these emails arrive promptly and when users need them.

ActiveCampaign Postmark has helped our sales, shipping, logistics, and other essential user notifications reach their inboxes without having to go through the hassle of getting them in the spam folder or getting lost. The emails arrive quickly and without delays, and it helps us to protect the quality of our domain Review collected by and hosted on G2.com.

We have not found anything that we dislike or makes us feel is not worth it. PostMark has a lot of options when it comes to sending transactional emails and email marketing campaigns.

Maybe we could have more automation options for managing better our domain health and, thus, not being blocked or marked as spam. Besidesthat, everything works amazing! Review collected by and hosted on G2.com.

I really appreciate the speed with which I receive emails. It's very important to me that customers receive emails on time because otherwise we can miss out on some business. Review collected by and hosted on G2.com.

I don't like the fact that sometimes Mustachio, which is the language used to write emails, is a bit old-fashioned and I have to find other ways to do things that could be done in a more simple way. Review collected by and hosted on G2.com.

It is really easy to integrate wih other programs and apis. Also, the templates they provide, have made our work easier. Review collected by and hosted on G2.com.

At this moment we haven't found anything that doesn't like us. Review collected by and hosted on G2.com.

We have been using Postmark to send transactional emails from WordPress websites using Postmark's plugin and it has help fix mail delivery issues for all sites without fail. It is easy to set up and the results are amazing. Review collected by and hosted on G2.com.

There isn't much to dislike, the pricing is fair we haven't noticed any service outages in last two years of using their services. But the muti-account/agency setup could be handled better. Review collected by and hosted on G2.com.

Much better than Sendgrid, which had endless deliverability problems even sending to e.g. Hotmail/Live.com addresses. UI is intuitive, use of 'sandbox' accounts is great for checking that your apps are sending messages correctly, and most importantly the actual deliverability is fantastic.

Literally nothing. Dedicated IPs are only available to a subset of customers, but you don't need one to get good deliverability (unlike with Sendgrid where, with exactly the same emails, we were seeing our IPs flagged for spam). Review collected by and hosted on G2.com.
