Campaigns — UTM parameter customization
You can now set custom UTM parameters on marketing campaigns. When a campaign is sent, utm_source, utm_medium, utm_campaign, and utm_content are appended to every tracked link, so downstream analytics attribute traffic correctly.
Transactional Email — per-contact pixel tracking consent
The sendAt header now honors per-contact tracking consent. If a contact has opted out of open tracking, the tracking pixel is omitted from that recipient’s message even when the template enables it.
