How does Amazon SES help improve email deliverability?

Amazon Simple Email Service (SES) significantly enhances email deliverability through features like email authentication and the option for dedicated IP addresses.

Email authentication methods, such as Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC), help verify that the emails sent are legitimately from your domain. This reduces the chances of your emails being marked as spam or rejected by recipient mail servers.

Additionally, using dedicated IP addresses allows you to manage your sending reputation more effectively. When sending emails, the reputation of the IP address is a critical factor in determining whether your messages reach the recipients' inboxes. With dedicated IP addresses, you can isolate your sending reputation from other users, resulting in improved deliverability rates, particularly for larger email campaigns.

While logging, real-time analytics, and encryption are valuable features, they do not directly contribute to enhancing email deliverability as effectively as authentication measures and the use of dedicated IPs. Logging helps in troubleshooting and gaining insights, analytics provides performance feedback, and encryption secures the content of emails, but they do not influence the overall acceptance of emails by recipient servers to the same extent as the correct answer does.
