I'm looking for paid STMP services like Postmarkapp.com. Postmarkapp.com is great, but it's prices are too high for me. I know that Smtp.com is also good (but I've failed to contact their sales manager for some weeks already).

Any other paid SMTP services available?

I recommend to use CritSend (http://www.critsend.com). It can be 10 as cheap as PostmarkApp with better deliverability.

Disclaimer: I'm the Founder of CritSend so heavily biased toward this service

From personal experience, I can say that while Critsend is good on deliverability and cheap, it has really bad customer service. – talonx Feb 20 '14 at 14:22


At its current iteration, it acts as a layer between your application and your SMTP server, neither of which we provide, but it has a strong backend UI, a great API, and a very robust template system that users love.

In the coming weeks, PostageApp is rolling out a hosted SMTP service, which means that it will become a great end-to-end solution for users like yourself looking to send emails through their application.

However, I do recommend that you give each of the services a try, there are many, just so you know what you and your application needs. (For example, some services do not let you have multiple addresses in an API call.) Would be very happy to chat if you have any questions, so just send me an email at jon@postageapp.com if you do!

Hope that helps.

Great, I'm throwing away my custom email and templating system for this because of your templating system. Do I get a discount? :) – Shawn Mclean Aug 1 '12 at 20:50
Where is the .net wrapper?! – Shawn Mclean Aug 1 '12 at 20:52

I think you should take a look at this table comparing most (if not all) companies that do SMTP as a service.

I personnaly use Mailjet, and they have some features that are either unavailable or out of my price range with their competitors... The reliability has also been pretty good
