Choose the sending Region first, verify the right identity and configure DKIM there, request production access if you need to reach unverified recipients, limit IAM permissions to the application’s sending needs, and build a tested path for bounce and complaint events. SES accepting a message means it accepted it for processing—not that it reached an inbox.
1. Choose an SES Region before creating an identity
Amazon SES identities, DKIM settings, sandbox status, and sending quotas are regional. Decide which AWS Region your application will send from before generating verification or DKIM records. If you send from more than one Region, create and configure the identity separately in each one; DNS records generated for one Region do not replace that Region-specific setup.

Plan for the same regional separation when requesting production access and configuring notifications. A setup that works in one Region does not establish that your account or identity is ready to send from another.

Choose an email-address identity when only one address needs to send. A domain identity is usually more practical for an application with multiple From addresses: for straightforward sending, it generally covers addresses and subdomains beneath the verified domain. Some address-level features still require that particular email address to be verified explicitly.
#1 Best Overall
| Identity choice | Best fit | Important distinction |
|---|---|---|
| Email address | A single sender address | Verify each address that needs to send, and explicitly verify an address when an address-specific feature requires it. |
| Domain | Multiple senders under one domain | For straightforward sending, it generally covers addresses and subdomains under that domain; it does not remove address-level requirements for certain advanced features. |
Publish the DNS verification records SES generates for the chosen identity and Region. AWS says DNS changes may take up to 72 hours to propagate, so an identity that is not verified immediately after publishing its records may simply need more time. Check the identity’s status in the same Region where the application will send.
3. Set up Amazon SES DKIM
DKIM lets SES sign mail so receiving systems can authenticate that signature against your domain’s DNS records. Select a signing method based on who should control the keys and how much control the application needs.
| Method | Key control | DNS and regional considerations |
|---|---|---|
| Easy DKIM | SES generates and manages the signing keys. It defaults to 2048-bit keys; a 1024-bit option is also available. | Publish the CNAME records SES generates. Configure the Region-specific records for every sending Region. |
| Deterministic Easy DKIM | Uses SES-managed Easy DKIM signing. | Supports replicating identities across Regions; configure the required identity and DNS setup in each sending Region. |
| Bring Your Own DKIM (BYODKIM) | You generate and manage the private key. | Supports 1024–2048-bit keys. Key generation and private-key handling become your responsibility. |
| Manual signing | Your application controls message signing. | Available for raw messages; choose it when application-level signing control is needed. |
For the usual Easy DKIM setup, add the CNAME records SES supplies to the DNS host for the domain, then allow time for DNS changes to propagate and confirm DKIM status in SES. Avoid copying records from another Region without checking whether they are the records generated for the identity in the Region you intend to use.
4. Move Amazon SES out of the sandbox
New SES accounts begin in the sandbox separately in each Region. In the sandbox, you can send only to verified recipient addresses or the SES mailbox simulator. AWS documents the sandbox limit as 200 messages per 24-hour period and one message per second. These are service limits, not a deliverability guarantee.
To send to ordinary, unverified recipients, request production access for the Region your application will use. Approval is specific to the account and Region. Production access removes the sandbox recipient restriction; it does not waive verification of the identities used as From, Source, Sender, or Return-Path.
5. Give the application only the SES IAM permissions it needs
Do not give a sending application broad SES administration access by default. AWS documents send-only policies using ses:SendEmail and ses:SendRawEmail. An SMTP integration needs ses:SendRawEmail at minimum. Grant only the calls the application actually makes.
- Where possible, restrict send permissions to the SES identity ARNs the application is allowed to use.
- Use conditions such as
ses:FromAddress,ses:Recipients, andses:FeedbackAddresswhen the application should be limited to particular sender, recipient, or feedback addresses. - Keep the distinction between IAM and SES sending authorization clear: IAM controls what the application’s user or role can call, while sending-authorization policies attached to identities govern delegated use. Cross-account sending authorization uses the identity policy mechanism.
Review the policy against the application’s actual sending path—API or SMTP, identity, and permitted addresses—rather than granting extra permissions to make an initial test pass.
6. Choose a bounce and complaint notification path
Bounce and complaint handling should be part of the sending system, not an afterthought. SES offers feedback email, identity-level Amazon SNS notifications, and configuration-set event publishing. Choose a route that your application or operations team can reliably receive and act on.
Best Value
- Used Book in Good Condition
| Method | Scope and operational fit | Watch for |
|---|---|---|
| Feedback email | SES forwards bounce and complaint notices through email. | If no notification method is configured, SES sends notices to the Return-Path address or, if absent, the Source address. |
| SNS identity notifications | Notifications are configured per identity and Region. | The SNS topic must be in the same Region as SES. This method is tied to the identity rather than selected by attaching a configuration set to each message. |
| Configuration-set event publishing | Publishes selected message events to a destination such as SNS, enabling broader event handling. | The relevant configuration set must be applied to each message. If email feedback forwarding is disabled but a message is sent without the configuration set, the documented email fallback can still apply. |
More than one notification method can produce duplicate notices. Decide which path is authoritative and make the receiving system safe to process duplicates. If you rely on configuration-set events, ensure every sending path attaches the intended configuration set; otherwise those messages may not follow the event route you expect.
7. Interpret events and stop sending when needed
Configuration sets can publish selected event types, including BOUNCE, COMPLAINT, DELIVERY, and DELIVERY_DELAY. These outcomes describe what happened after SES accepted a message for processing, not what the initial API response established.
- BOUNCE: AWS defines this event as a hard bounce. Soft bounces appear when SES gives up after retrying.
- COMPLAINT: A recipient marked a delivered message as spam.
- DELIVERY: SES reports a delivery outcome; it is not proof that the message landed in the inbox rather than another folder.
- DELIVERY_DELAY: SES reports a delay in delivery.
Have your event consumer update application state and suppress or otherwise stop sending to problematic recipients according to your own sending policies. Decide how to handle each event type, make processing resilient to retries or duplicate notices, and monitor the route so an event destination failure does not silently leave the application sending to recipients it should have stopped mailing.
8. Test event handling, not just credentials
A successful API call checks that SES accepted a request for processing; it does not establish delivery or inbox placement. Test the downstream path as well: SES’s mailbox simulator supports simulated successful delivery, bounce, complaint, out-of-office, and suppression-list cases. Use those cases to confirm notifications arrive, the application interprets them correctly, and recipient state changes as intended. Simulator results exercise the event workflow; they do not prove placement in real recipients’ inboxes.
