Amazon SES vs Postmark: What are the differences?
Introduction
This Markdown code provides a comparison between Amazon SES and Postmark highlighting the key differences between the two email service providers.
Pricing: Amazon SES offers a flexible pricing structure where users pay for the number of emails sent and any additional features used, while Postmark offers a fixed pricing plan based on the number of emails sent.
Deliverability: Both Amazon SES and Postmark take measures to ensure high deliverability rates. However, Amazon SES's deliverability is affected by the reputation of the sender, while Postmark has a higher reputation and thus better deliverability overall.
Sender Authentication: Amazon SES requires its users to set up and manage DKIM, SPF, and DMARC records to authenticate their emails, while Postmark handles sender authentication automatically.
Integration Options: Amazon SES provides a wide range of integration options, allowing seamless integration with various platforms and systems. In contrast, Postmark has limited integration options and is mainly focused on providing an API-based solution.
Email Templates and Personalization: Amazon SES provides basic email template functionality, allowing users to design and customize templates. Postmark, on the other hand, offers advanced email template options with built-in personalization features.
Support and Documentation: Amazon SES offers extensive documentation and community support, including forums and user guides, providing users with resources to troubleshoot issues. Postmark provides dedicated support from their team and has a reputation for excellent customer support.
In Summary, while both Amazon SES and Postmark are reputable email service providers, the key differences lie in their pricing models, deliverability rates, sender authentication methods, integration options, email template functionality, and support offerings.
We chose Postmark as our transactional email service for several reasons:
Laser-focus (at the time) on transactional email - their success/speed/reliability with delivering transactional email is amazing. Note, they have now branched out and offer marketing/broadcast email services too.
Developer-friendly - Awesome docs and resources. Their Rail gem integrates directly with ActionMailer so nearly all of our code worked without changes.
Servers - You can set up "Servers" for different mail streams/workflows to keep things separate and easy to review.
Bootstrapped - Wildbit (who makes Postmark) is bootstrapped just like the Friendliest.app and they offer a service credit to other bootstrapped startups.
Of course we chose Coresender to send our own transactional emails :) So I thought I'll let you know how we use it.
We set up separate sending accounts for all company needs, eg. transactional emails, monitoring alerts, time to inbox. We even configured our office printers to send emails through Coresender.
We have a real-time and extremely usable view into what emails go through each account, so each time anybody reports an email not arriving we're able to assist them in a few seconds
We utilize our message timeline feature, so we can learn eg. if people are clicking on password reset links
We always know how many of our onboarding emails are being opened which helps us improve them
Finally, we have full controll over our suppressions lists, so we can add (and remove!) from them whenever necessary.
To sum up, at Coresender we're eating our own dogfood and it helps us stay connected to the product and understand our customers better.
While building our authentication system, we originally picked Mailgun. However, emails took minutes to arrive and some of them didn't get delivered - or got delivered to spam.
We started looking for a new provider, and settled on Postmark. We love that they track time-to-inbox, it makes me feel they really care about going above and beyond to provide a good service.
