Manage contacts, define segments, and schedule campaigns from the same product surface as transactional email. ZSend gives product teams one place to build the audience side of a send.
Repository checkSource-registered API handlers cover contacts, segments, and campaign create, schedule, pause, and resume operations.
The API and CLI support contact operations inside a contact book. Create a contact, update its details, upsert an existing record, or remove it when it should no longer be part of the audience.
Segments are managed against a contact book and can return the contacts that match their filter. That gives campaigns a reusable audience definition instead of a one-off export.
Campaigns can be created, scheduled, paused, resumed, and deleted through the registered API handlers. Campaign content also needs an unsubscribe placeholder, keeping the required opt-out path part of the workflow.
