Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The SES integration can report a magic-code email as sent without delivering it when credentials are missing, temporary credentials can stop working after expiry, and mixed provider settings can create an identity with one provider while sending through another. These configuration and runtime failures can prevent authentication emails from being delivered, so the PR is not merge-ready until they are fixed or explicitly accepted.

In `@client/www/app/docs/self-hosting/page.md`:
- Around line 75-109: Update the Amazon SES setup documentation near the sending
and verification instructions to state that sandbox accounts can send only to
verified recipients in the selected AWS Region. Instruct users to request
production access for that Region or verify every recipient identity while
testing.
In `@client/www/components/dash/auth/Email.tsx`:
- Around line 341-350: Update the DNS disclosure near the DnsRecord rendering to
make the optional label conditional on the identity type: SES domain
verification records must be presented as required, while retaining the optional
wording for other record types. Use the existing domain-identity state or symbol
in the Email component rather than adding a separate source of truth.
In `@server/resources/migrations/125_email_sender_provider_identity.down.sql`:
- Around line 1-5: The down migration for app_email_senders must not restore
postmark_id to NOT NULL while SES rows can contain null values. Define an
explicit rollback policy before the ALTER COLUMN step: either make the migration
irreversible once SES data exists or remove/convert SES-dependent rows so all
remaining postmark_id values satisfy the constraint, then drop the provider
constraint and columns.
In `@server/src/instant/email_router.clj`:
- Around line 32-35: Update the SES routing condition around
config/aws-ses-enabled? so SES is selected only when SES credentials are present
and neither Postmark nor SendGrid credentials are configured; otherwise preserve
the existing provider-routing behavior and identity selection.
In `@server/test/instant/ses_test.clj`:
- Around line 70-72: Qualify the thrown-with-msg? assertion in the SES test with
its clojure.test namespace, or add thrown-with-msg? to the namespace’s :refer
list, so the test namespace resolves the symbol during compilation.

- Around line 115-122: Update ses/send! so the disabled-SES branch throws an
email-send or configuration error instead of recording telemetry and returning
nil, ensuring explicit SES selection fails the magic-code request rather than
reporting success. Preserve the existing behavior for enabled SES and use the
established error-handling conventions.
- Around line 30-43: Update credentials-provider and the delayed SesV2Client
setup so AWS_SES_SESSION_TOKEN uses refreshable credentials that renew before
expiration, rather than StaticCredentialsProvider retaining one session
indefinitely; alternatively reject session-token configuration unless refresh
support is available. Preserve the existing long-lived client behavior for
non-session credentials.

Instant Cloud stays on Postmark/SendGrid. Self-hosted operators can send magic-code mail through SES v2 and verify custom senders as SES domain or email identities.
Drop the extra identity namespace, raw MIME builder, and sender-identity-type API. Keep Postmark custom-sender logic in app-email-sender and add a small SES domain-identity branch.
Document the SES sandbox, mark SES DKIM records as required, make the down migration safe after SES senders exist, and refer thrown-with-msg? in the SES tests.
SES rejects raw Unicode in from/to address strings. ASCII names stay plain so the common Instant sender format is unchanged.
Unverified From identities fall back to the default sender the same way Postmark signatures do. Other SES failures become the typed email-send-failed error from instantdb#2864.
Static session tokens cannot refresh, so they are not supported. If SES is selected without access keys, send now errors instead of returning a successful no-op.

Why
Self-hosted Instant can already send magic-code email through Postmark or SendGrid (
#2863). Many operators already have Amazon SES and would rather not add another vendor.This adds SES as a third self-hosted provider. Instant Cloud is unchanged: hosted prod/staging (
aws-env?) never selects SES, even ifAWS_SES_*orINSTANT_EMAIL_PROVIDER=sesis set.How to enable (self-hosted only)
Dedicated SES credentials, not the MinIO/S3
AWS_ACCESS_KEY_IDpair used for file storage:If no Postmark or SendGrid token is set and the SES keys are present, SES is selected automatically. The IAM principal needs SES v2
SendEmail,GetEmailIdentity, andCreateEmailIdentity.What changed
