Flowmailer vs. Postmark

If email deliverability is important, then Postmark is king. I've used all sorts of providers, with dedicated IPs and without. Postmark has always had the best deliverability and has resulted in the least amount of customer service time wasted dealing with users who simply did not receive an important email from us. It is pricier than other options, but it's well worth it if deliverability is at all important to you.

• Great, helpful customer support (rarely needed)
• Reliable product
• Well thought out interface, easy setup
• Great ongoing visibility into status of emails sent through Postmark

• Not many cons since it's pretty straightforward, and if email delivery service was often impacted, we'd most likely find a new provider.

The only thing that confused me initially was that if you don't put a specific sender email into the Wordpress plugin settings (I use Postmark exclusively with Wordpress site), it won't send emails. I thought that having selected the option to send via any @domain.com email, I wouldn't need to fill out a specific email to send from, but that isn't the case. I sorted that out quickly with support.

Postmark has been an excellent solution for our business needs. We have been with them for years and have no intention of changing providers anytime soon. Support was excellent as we were getting started and their API documentation made implementation quick and easy

We felt Postmark's focus on transactional emails and their use of shared domain reputation made them stand out. We also like their user interface and ability to have many virtual email servers. Pricing was competitive and after a trial we saw a big increase in deliverability rates. Therefore it was an easy decision to use Postmark over other providers.

• It is really "set and forget." I have not had any issues that I've needed to deal with. It just works.
