* feat: support standard AWS env vars and default credential chain
Replace non-standard AWS_ACCESS_KEY / AWS_SECRET_KEY with the AWS-standard
AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY. The old names are kept as
fallbacks in the runtimeEnv for backward compatibility.
Both vars are now optional. When omitted, the credentials object is not
passed to SESv2Client, STSClient, or SNSClient — the AWS SDK then falls
back to its default provider chain (IAM roles, ECS task roles, instance
profiles, etc.), which is the recommended approach for cloud-native deployments.
Closes#316

* Potential fix for pull request finding
Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>
* refactor: extract shared getAwsCredentialOptions helper and add partial-config guard
- Move the credential spread logic into a single credentials.ts helper
so SESv2Client, STSClient, and SNSClient all share one implementation
- Throw a clear error if only one of AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY
is set, preventing silent fallback to the default provider chain with a
half-configured environment

* fix: align AWS env vars in docker and docs
* fix: use alias import for AWS credentials helper

* feat: add REDIS_KEY_PREFIX env var for Redis ACL namespace isolation
Adds optional REDIS_KEY_PREFIX env var that prefixes all Redis keys
(BullMQ queues via `prefix` option, cache/lock/rate-limit keys via
`redisKey()` helper). When unset, behavior is unchanged (BullMQ
defaults to "bull:", cache keys are unprefixed).
This enables self-hosters using Redis ACL multi-tenancy to restrict
useSend to its own key namespace (e.g. `~usesend:*`).
16 files changed across env schema, Redis module, 9 BullMQ queue/worker
files, and 5 direct Redis key operation sites.
* docs: add REDIS_KEY_PREFIX to self-host assets and fix docker run example
Add REDIS_KEY_PREFIX env var to docker/prod/compose.yml, .env.example,
.env.selfhost.example, and self-hosting docs. Fix missing trailing
backslashes in standalone docker run example.
* fix(redis): disable ioredis ready check and BullMQ version check
Redis ACL blocks INFO command (in @dangerous category). ioredis uses
INFO for ready check, BullMQ uses it for version detection. Without
these flags, BullMQ workers fail to initialize and silently stop
processing jobs.
- Add enableReadyCheck: false to ioredis connection
- Add skipVersionCheck: true to all 5 Queue + 5 Worker constructors
* fix(redis): add skipVersionCheck to remaining BullMQ job queues
Add skipVersionCheck: true to Queue and Worker constructors in all 4 job
files (campaign-scheduler, cleanup-email-bodies, usage-job,
webhook-cleanup) to match the pattern already used in service files.
This prevents BullMQ version mismatch errors when using REDIS_KEY_PREFIX
with Redis ACL namespace isolation.
* feat: add customizable contact double opt-in flow
* test: add double opt-in service coverage
* fix: address review comments for double opt-in PR
- Make pending status conditional on doubleOptInEnabled flag
- Backfill legacy unsubscribeReason for reliable pending detection
- Add doubleOptInContent to contact book listing select
- Fix duplicate toast on DOI editor subject save failure
- Harden searchParams parsing against string[] values
- Make default DOI template use link mark for clickable URL
- Make public API create+update atomic via transaction
- Prevent contact upsert failure when DOI email send fails
- Fix empty string template variable replacement

* fix: harden double opt-in confirmation safeguards
Preserve explicit unsubscribe intent in DOI flows and prevent confirmation links from re-subscribing opted-out contacts. Also sanitize subscribe-page error messaging and use timing-safe hash comparison for link verification.
* ui stuff
* fix: require doubleOptInUrl in double opt-in templates
* feat: add configurable from address for double opt-in emails
* feat: add resend confirmation flow for pending contacts
* fix: move subscribe confirmation to explicit POST flow
* test: add contact book public API endpoint coverage
* docs: add double opt-in documentation and update OpenAPI spec
Add a user guide for the double opt-in feature covering setup, contact
statuses, email customization, template variables, and best practices.
Update the OpenAPI spec to include doubleOptIn fields in all contactBook
request/response schemas.

* fix: prevent premature webhook auto-disable and allow re-enable
Use persisted failure counters when deciding auto-disable status and restore dashboard re-enable flow so webhooks are not deactivated unexpectedly after reset.
* fix: count webhook failures per failed call
Only increment consecutive failure counters after a call exhausts retries, while keeping the 30-call auto-disable threshold and stale-state protection.
* fix(docs): correct webhook SDK package name (#363)
* test: isolate webhook unit suite from mailer deps
Mock limit service in webhook unit tests so Vitest does not resolve team-service and mailer paths requiring usesend-js during CI.
- new edit button in /dev-settings
- new updateApiKey mutation in api router
- new edit dialog-component
- new update-function in api-service
- changed sorting of api-key query to avoid list items jumping after updates
* fix: sync suppression list removal with AWS SES (closes#324)
When removing an email from the suppression list, now also removes it from
AWS SES account-level suppression list across all regions where the team
has domains configured.
- Add deleteFromSesSuppressionList helper to ses.ts
- Update removeSuppression to query team domains for unique regions
- Use best-effort pattern: AWS failures don't block local DB deletion
- Handle NotFoundException gracefully (email not in SES list)
* fix: correct failure detection logic for SES suppression removal
deleteFromSesSuppressionList returns false on error (never throws),
so check for fulfilled promises with value === false instead of
rejected status.
* fix: account for rejected promises in SES suppression removal
Updated the filter logic for Promise.allSettled to include 'rejected'
status as well as 'fulfilled' with a 'false' value. This ensures that
any errors occurring before the try block in deleteFromSesSuppressionList
are correctly caught and logged.
* Correct API reference in Go package documentation
Updated description to reference the useSend API instead of Unsend API.
* Update documentation to reflect useSend branding
Added a issue to the package maintainer.
If maintainer isn't actively maintaining the package. Will fork it.
* fix(docs): remove community section and update Go SDK documentation
- Remove community section until content is ready.
- Update Go SDK docs to useSend implementation.
* feat: add web test framework with infra-backed suites
* fix: honor DATABASE_URL env in integration prepare script
* fix: apply web test review feedback
* fix: streamline web test infra lifecycle and workflow scope
* feat(python-sdk): add webhook verification and event handling
Add webhook support to the Python SDK matching the JS SDK implementation:
- Add Webhooks class with verify() and construct_event() methods
- Implement HMAC-SHA256 signature verification with timing-safe comparison
- Add timestamp validation with configurable tolerance (default 5 minutes)
- Add comprehensive webhook event types (18 events: email, contact, domain, test)
- Add WebhookVerificationError with typed error codes
- Export webhook constants (headers) and types
* fix(python-sdk): harden webhook parsing and typing
Normalize invalid UTF-8 webhook payloads to INVALID_BODY errors so verify() safely returns false, and narrow base email webhook event types to avoid discriminated-union overlap. Add regression tests for both paths.
* chore(python-sdk): bump package version to 0.2.9
* feat(python-sdk): add local webhook test example project
Add a runnable Flask receiver and signed webhook sender under packages/python-sdk/example, and link it from the Python SDK README for local verification.

The warning and limit-reached notification emails were being sent
multiple times because of a race condition: concurrent workers could
both read the Redis cooldown key as empty (GET), both send emails,
then both set the key (SETEX). Replaced the non-atomic GET + SETEX
pattern with a single atomic SET ... NX EX that claims the cooldown
slot before any emails are sent. Also increased cooldown from 6 hours
to 24 hours so each notification is sent at most once per day.
