Recently, the Amazon Appstore for Android featured Read It Later Pro as the Free App of the Day. The extremely popular and useful application allows users to save what they find on the web to watch and read on any device and at any time – a “DVR for the web,” states The New York Times.

Founded in 2007, the company already boasts 3.5 million users and sees millions of articles saved each week through their very user-friendly and seamless service.

Also, the company “runs the entire Read It Later operation on Amazon Web Services [AWS],” states founder Nate Weiner. “We take advantage of EC2 for our servers, ELB for load balancing, S3 and EBS for storage. We also use Amazon Simple Email Services [SES], which has simplified our e-mail communications and made them more effective.” Although very excited about the Free App of the Day promotion, the Read It Later team expressed some concern over the large number of expected new customers and the impact on their 50K daily e-mail limit through SES.

According to Read It Later CTO and Engineer Matt Koidin, the internal teams at Amazon moved quickly to address a solution for this use case. “We initially thought we would need additional development to work around the e-mail limit… but our account manager was able to coordinate with the AWS team to increase the limit for the day,” Koidin said.

Koidin and team see this as another example of the Amazon Appstore’s ability to provide an advantage through its network of services for developers. “Having Amazon not only run the promotion, but work with the broader Amazon organization (i.e. AWS) to provide some assistance so it didn’t overwhelm us or require additional work, shows they are aligned as a partner to make this a success for everyone involved,” added Koidin.

The team at Read It Later was happy to report that the promotion resulted in “one of our largest days of new user acquisition ever” and “we’ve seen our transaction level sustain at a higher level than prior to the promotion.” They see more exciting opportunities down the road to incorporate additional Amazon services for developers.  When asked if they would run the Free App of the Day promotion again, Koidin replied with a simple, “Absolutely.”
