What are SendGrid and Postmark?

SendGrid logo
SendGrid

SendGrid is a complete email delivery system that works in the cloud. You can use it in two ways: through an API for automatic emails from your website or app, or through a user interface for creating marketing campaigns.

The Email API helps developers send transactional emails programmatically using popular programming languages like Python, Node.js, PHP, and Ruby. It connects to your application through simple code or SMTP relay.

The Marketing Campaigns tool lets marketers create beautiful emails using drag-and-drop editors, manage contact lists, segment audiences, and track email performance through detailed analytics. Both services include features like email validation to check addresses before sending, dynamic templates for personalization, and real-time delivery monitoring to ensure high inbox placement rates.

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.
