Campaign test send via API, coupon notification management and domains

A new POST /campaigns/{id}/send‑test endpoint lets you send a test version of a draft campaign to specified email addresses (max. 5) with specific merge tag values. The test does not change the campaign status and is not counted in statistics. Partners and agencies integrating via API can test the final look of a campaign including personalisation without having to open the app.

You can now disable automatic alerts about approaching expiry and depleting coupon stock for each coupon folder. The Notify on low stock toggle is on by default and controls both email and in‑app notifications. When enabled, a notification is sent when stock drops below 15% or below a custom limit you set. The main folder now also supports a custom limit setting.

Previously the domain type (sending or transactional) would overwrite each other ‑ a domain could only ever have one type. A single domain can now be configured as both sending and transactional at the same time, with each type managed independently. The POST /domains API endpoint now requires a valid type parameter (sending or transactional) ‑ an invalid value returns 422 instead of being silently accepted. The domain listing may return two records with the same name differing by type for such domains. We recommend using a unique domain for both bulk sends and transactional emails.

We resolved potential issues with connecting the MCP server to third‑party AI tools, particularly Cursor. If you experienced connection problems, we recommend disconnecting and reconnecting the server following the updated help guide.
