Amazon SES (Simple Email Service) is a cloud email service from Amazon Web Services that an application uses to send and receive email in high volume. Transactional email is a message triggered by a user's action, such as a password reset, a receipt or a shipping notice; SES also sends marketing campaigns and newsletters.
An application sends mail through the SES API, the SMTP interface (the standard protocol that mail servers use) or an AWS SDK. Email can go out from shared, dedicated or owned IP addresses. Sender statistics and deliverability tools, including the Virtual Deliverability Manager, help messages reach the inbox instead of the spam folder. For incoming mail, Mail Manager protects and automates the handling of received email. AWS states that SES handles more than a trillion emails a year.
SES is billed by usage with no minimum fee: à la carte prices per 1,000 emails and per gigabyte of attachments, or tiered monthly plans (Essentials, Pro, Enterprise) for larger senders.
