Summary

Out of the five services mentioned, Postmark is the most expensive. The company positions itself as a high-end service for good reason. Postmark only uses the best hardware and software to maintain high deliverability rates and to keep your information secure.

Amazon SES

Summary

On the flip side, Amazon SES is the cheapest service on this list. At $0.10 per thousand emails, it’s hard to beat. However, multiple users claim the AmazonSES interface is cluttered, and poking around their API can be a headache.

Consider your budget, technical expertise, and patience if you’re contemplating Amazon SES. It’s the cheapest option around, but at the same time, Amazon delivers subpar services, features, and customer support. You can’t use dedicated IP addresses, you are only able to send emails from verified addresses, and the analytics are extremely limited.

Amazon SES is the most basic service. If you’re working with a restricted budget and only need to deliver emails into inboxes, you should stick with Amazon.

Pricing

With Amazon SES, you only pay for what you use. See here for more details.

Overall

  • Extremely cost-effective and scalable
  • Best for small to mid-sized businesses
  • Integration with other Amazon web services
  • Ability to send emails via API or SMTP

Mailjet

Mailjet is a gateway email marketing tool. It’s easy to use but competes on a Postmark level when it comes to features and performance. It’s a great alternative to MailChimp, and the platform is slowly but surely trying to catch up to its competitors.
