Live domain status updates, Basic Auth for webhooks and campaign fixes

The Domains page previously checked the current verification status by repeatedly polling the server. The status now updates immediately once the background check completes ‑ for a newly added domain, you now see the verification result within seconds instead of waiting up to half a minute.

Webhooks from automations, from a contact's status change in a list (e.g. unsubscribe), and message events from campaigns can now have optional Basic Auth authentication configured via the request header. Useful for clients who only want to accept verified requests.

Transactional domains could keep showing a stale verification status even after a successful revalidation ‑ the domain worked and sent emails correctly, only the display in the Domains section didn't reflect reality. The status display is fixed.

In the Safari browser, checkboxes could not be checked and the options dropdown could not be opened in the Contact update trigger settings ‑ the elements would instead visually shift to the centre of the screen. The issue is fixed.

The list of contact lists for the last sent campaign on the dashboard did not wrap onto a new line for longer content, forcing horizontal scrolling. After a page cache refresh, list names were also temporarily replaced with N/A. Both issues are fixed.

In some cases, an existing Brand Kit in EMA was not displayed even though it was saved and available in the data. Brand Kit display is fixed.

For Sklik integration circles using RFM segmentation, the transferred contact list could be empty or outdated due to a timing mismatch between the daily RFM segment recalculation and the sync to Sklik. Synchronisation now runs only after the segment recalculation has completed.
