* 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.
* 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.
