Postmark

Postmark is an email delivery service that sends your automated emails using modern technology. You can connect it to your website or app through their API or SMTP settings, and it handles the rest. Unlike regular email services, Postmark specializes in transactional emails - the important messages your customers expect right away.

The platform includes tools for tracking email delivery, viewing open rates, and managing bounce notifications. It also offers ready-made email templates that look good on all devices. Postmark separates your automated emails from marketing emails to keep delivery rates high.

The service runs on reliable servers around the world and includes helpful support from email experts. You start with a free account that includes 100 emails monthly, and you can upgrade when you need more.

Amazon SES

Amazon SES is a service that sends and receives emails for your business through the internet. Instead of running your own email server, you use Amazon's system to handle everything. You can send marketing campaigns, order updates, password resets, or any other emails your application needs.

The service runs on Amazon's reliable network of data centers around the world. This means your emails get delivered quickly and reach inboxes instead of spam folders. Amazon SES checks your sender reputation, helps you follow email best practices, and provides reports showing how your emails perform.

You access Amazon SES through simple tools like web APIs, standard email protocols, or the AWS management screen. It takes minutes to start sending emails once your account is set up and verified.
