Amazon SES enables businesses to send marketing, transactional, and other types of emails at scale without the need to manage their own email infrastructure. It offers flexible sending options, including API and SMTP integration, and supports both sending and receiving emails. The service provides high deliverability rates, detailed analytics, and robust security features to protect sender reputation. Businesses benefit from a pay-as-you-go pricing model, eliminating upfront costs and contract negotiations. SES also integrates seamlessly with other AWS services, allowing for advanced automation and workflow customization.
