Postmark is an application that helps web-app developers make sure their subscriber emails are getting into their users’ inboxes without getting labeled as spam. Created by the team behind Newsberry—the email marketing application—Postmark works behind the scenes for web-app developers and handles email bounceback issues, whitelisting, ISP throttling, feedback loops, reverse DNS, and delivery monitoring, so the developers themselves don’t have to.
When you sign up for Postmark, you can send 1,000 emails without paying a dime, after which you’ll be asked to pay $1.50 for each thousand emails you send out. Confirm your business email address by creating at least one “sender signature,” and create separate servers for each application you run. Choose between using a shared server or a dedicated serve—based on how many emails you plan on sending out—drop the API code into your web-app, and you’re ready to start sending emails to all of your subscribers. Email messages sent through Postmark can always be tracked, and you can tell right away which ones are being bounced back from their recipients’ email inboxes.
Although Postmark will handle all transaction emails—which are emails that a company sends out to subscribers based on an action or event—the application
is not set up to manage bulk marketing campaigns or spam the inboxes of people whose email addresses were acquired by third-party vendors. Not only does this cut down on the amount of spam that people get in their inboxes on a daily basis, but it decreases the amount of complaints that come into Postmark and increases the odds that the important emails from web-app developers are getting where they are supposed to go. For developers looking for a better way to send automated messages to their online subscribers, Postmark is a great application that’s worth trying out.
