What are MailerSend and Postmark?
MailerSend is a cloud-based email service that focuses on sending emails automatically from your apps or websites. Unlike regular email services for marketing campaigns, MailerSend specializes in sending individual messages triggered by user actions.
The platform provides both an API for developers and a simple interface for non-technical team members. You can send emails through code or by using their built-in SMTP service. The system tracks every email you send, showing you when it was delivered, opened, or if there were any problems.
MailerSend helps keep your emails out of spam folders with built-in tools for checking email addresses before you send and monitoring your sending quality. You can also receive incoming emails and process them in your application automatically.
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.
