Frequently Asked Questions
- What's the difference between Amazon SES and Amazon SNS?
- Amazon SES is for sending email messages (transactional or marketing) via SMTP or API and managing email deliverability signals like bounces and complaints. Amazon SNS is a pub/sub messaging service used to send notifications to subscribers (HTTP endpoints, SQS, Lambda, email as a basic notification channel). Use SES when email delivery and deliverability are the primary goal; use SNS when you need fan-out notifications to multiple systems and protocols.
- When should I use Amazon SES?
- Use SES when your application needs to send reliable outbound email at scale—such as password resets, sign-up verification, receipts, alerts, and newsletters—and you want API/SMTP integration, domain authentication (SPF/DKIM), and feedback handling for bounces/complaints. It’s a good fit for SaaS apps, e-commerce, and any system that generates event-driven emails.
- How much does Amazon SES cost?
- SES pricing is primarily based on the number of emails you send, plus additional charges for data transfer and optional features (for example, dedicated IP addresses). Costs also vary depending on whether you send through the SES API/SMTP and where your workload runs. Check the AWS SES pricing page for current per-email rates and regional details, and estimate based on monthly send volume, attachment sizes, and whether you need dedicated IPs.
