Reddit is a network of communities where individuals can find experiences built around their interests, hobbies, and passions. With over 430 million global users monthly, Reddit is home to the most open and authentic conversations on the internet.

At Reddit, we want to help our users stay up-to-date with content and discussions that interest them the most. As we continue to evolve our engagement strategy, we needed an email provider that was flexible and could scale to support our millions of global users. We started using Amazon SES a few years ago to meet those needs and haven’t looked back.

Netflix is the world's leading internet television network, with more than 150 million members in 190 countries. The Netflix Messaging team builds the systems and applications to communicate with members across various channels and relies on Amazon’s SES for email delivery.

Before we migrated to Amazon Simple Email Service (SES), Netflix had to maintain an in-house solution for sending emails. This in-house solution carried its own operational overheads, including running dedicated servers with email delivery software and optimizing email sending practices for each Internet Service Provider. We evaluated several email delivery solutions and decided on Amazon SES because it is flexible, affordable, highly scalable, has global reach, and promises excellent deliverability. Through a combination of the SES Dedicated IP offering and some strategies implemented on our end, after migrating to Amazon SES, we were able to streamline operations, improve Inbox Placement and increase our email sender reputation score.

There are over 1.2 billion people learning a language and the majority are doing so to gain access to better opportunities. Duolingo is the #1 most downloaded education app with 300 million total users worldwide. Duolingo's mission is to make language education free, fun and accessible for everyone in the world.

“Learning a new language is a very difficult task and we know that the hardest part is staying motivated so you stick with it. We use email to encourage our learners to practice every day and turn learning into a habit. Since 2012 when Duolingo launched, we've been using Amazon Simple Email Service (SES). We use it whenever we send emails to our customers, such as daily practice or newsletters. We chose Amazon SES because it integrates nicely with the rest of AWS’s powerful offerings, and we continue to use it because it has the scalability to send huge volumes of emails to hundreds of millions of learners reliably.”

“Canvas was born in the cloud, as the first fully SaaS learning management solution (LMS), and our platform supports K-12, Higher Education, and corporate continuing education. The heart of learning is the engagement between teacher and student. We use notifications in our applications to initiate communications through activities like changes to course content, grading, and scheduling time with an educator. Email is an important part of those communications and keeping students up to date. We looked for a global email partner that could provide scale to support our 4,000 customers across a variety of geographies, and Amazon Simple Email Service (SES) was the service that could meet our needs. We are also able to ensure important emails get to our students through sender configurations like DKIM and SPF. The email sending and deliverability of Amazon SES has helped us fulfill our mission of making education easy and accessible to everyone.”
