Amazon said today it is launching a bulk email-sending service for businesses and developers as part of its web services.

The new service called Amazon Simple Email Service (Amazon SES) integrates with other Amazon Web Services (AWS), to send email from other apps being hosted on services such as Amazon EC2.

Through a simple API call, businesses can now access a  scalable email infrastructure to  communicate to their customers. For high email deliverability, Amazon SES uses content filtering technologies to scan a business’s outgoing email messages to help ensure that the content meets ISP standards. The email message is then either queued for sending or routed back to the sender for corrective action.  Amazon SES provides a built-in feedback loop, which includes notifications of bounce backs, failed and successful delivery attempts, and spam complaints.

Pricing for Amazon SES is  $0.10 per thousand email messages sent. Additionally, a customer can send 2,000 email messages for free each day when these emails originate from Amazon EC2 or AWS Elastic Beanstalk.

“Customers have consistently asked us for the ability to send large quantities of high-quality email from Amazon EC2. Amazon SES makes it very easy for businesses to send email from applications running on Amazon EC2 and other AWS services,” said Adam Selipsky, Vice President, Amazon Web Services.

“With Amazon SES, businesses no longer have to worry about the details of building and maintaining their own email-sending solution.”
