How it works

1
Sync your contacts
Import a CSV, sync via API, or reuse the contacts already created by transactional sends.
2
Build the campaign
Design in the visual editor or bring your own HTML — variables and blocks included.
3
Target a segment
Send to a list, a saved segment, or everyone who matches a property or event filter.
4
Schedule and track
Send now, schedule for later, or trigger via API — then watch opens, clicks and unsubscribes.

One platform

Campaigns on the contacts you already have

No second tool and no re-importing: campaigns use the same contacts, domains and suppression list as your transactional mail.

Precise targeting

Send to a static list or a segment that recalculates from contact properties and list membership.

Template-driven

Build campaigns from your versioned templates, personalised per contact with {{ variables }}.

Reputation-safe by default

Unsubscribed and suppressed contacts are skipped on every send, so one bad list can't hurt the rest.
