Amazon Simple Email Service, or SES, provides cloud-based email as a service. Amazon SES simplifies sending emails from applications being hosted on services such as Amazon EC2. Because email services are often used by spammers, Amazon SES provides each user with a quota. EC2 users can send 2,000 emails per day for free.
The service allows developers to send either raw email or formatted email using Amazon's SMTP servers. Any spam complaints or other issues bubble back up to the developer. Similar to other Amazon Web Services, Amazon SES charges per gigabyte for transfer in and out of its systems.
Email continues to be a critical part of most web applications today. Despite the rise of various methods of reaching out to users, transactional email continues to grow. Many developers prefer to offload the email functionality of their application to a service which does the heavy lifting of not just delivering your email but also provides tracking and other various other services. PostageApp, a provider of Email Management Services, has just announced a new version of its product that includes a new delivery engine, analytics and new plans.
Email, which is one of the oldest services available on the internet, is a key mechanism via which you can reach out to your users. Over the last year, the number of services providing this infrastructure as a service has grown to include 6 email sending APIs. The newest, Amazon Simple Email Service, validates the market.
