Email Delivery Service.

Unlike marketing emails, your transactional emails should reach your customers instantly. PostMark offers you a fast email delivery service that you can rely on.

The transactional email contains important information that customers expect to receive as soon as you send them. But the delays in this process can frustrate and confuse your customers and could cost your business in the long run.

To help you keep up with these expectations, the Postmark email service ensures that your emails go directly into client’s inboxes instead of going to spam folders and are delivered as fast as possible.

For example, websites running on WordPress can use plugins like the Postmark for WordPress plugin to generate and send transactional emails directly from the website. This can avoid any delay that can result from manually running a separate computer software or cloud-based application.

Also, the Postmark email service only allows dedicated IPs to high-volume senders. On the other hand, low and mid-volume senders are given shared IPs with established sender reputations.

This allows lower-volume senders to obtain optimum delivery from the get-go instead of warming up a dedicated IP address and building their sender reputation from scratch.

Your customers don’t need to frantically refresh their inboxes when you send them emails via PostMark.
