Subscribers with a paper trail
Lists hold contacts, their consent state, and arbitrary metadata for personalization, with double opt-in as a first-class setting, not an afterthought.
Metadata that feeds your templates
Each contact carries arbitrary JSON metadata (a first name, a plan tier, a signup source), available as template variables like {{ first_name }} in every send to that list. Bulk import takes a contacts array on the same endpoint; new accounts importing bursts of cold contacts are screened for abuse.

}'Three states, no ambiguity
Contacts are pending, subscribed, or unsubscribed, and only subscribed contacts receive broadcasts. With double opt-in enabled, new contacts confirm by email before activation, which is effectively required for EU marketing. Lists can auto-send a welcome email on subscription, deduplicated so nobody is welcomed twice.
