Everything you need
to run a campaign program.
Built for teams that ship marketing alongside product — not as a side project.
Best-in-class drag-and-drop editor
The same Topol editor trusted by 40,000+ companies. Synced sections, multilingual templates, version history, draft and publish workflow — built for teams that actually ship.
Contact lists and segmentation
Manage audiences without a spreadsheet. Filter by attributes, behavior, or custom events. Segments update in real time as your data changes.
Campaign analytics
Opens, clicks, conversions, unsubscribes — per campaign and per contact. Compare variants, surface what works, and feed insights back into your product.
Same deliverability stack
Marketing and transactional share one sending reputation. SPF, DKIM, DMARC, custom tracking domains, and dedicated IPs are first-class — not add-ons.
Version history and approvals
Roll back any change. Add reviewers before a campaign goes out. Audit every send to a known author and a known template version.
Audiences that
stay in sync.
Push contacts from your product via API or webhook. Segments update in real time as attributes and events change — no nightly export, no stale lists.
- Import via CSV, API, or webhook
- Double opt-in flows out of the box
- GDPR-aware unsubscribe and consent tracking
- Custom fields and dynamic placeholders
- Real-time segments — no nightly batch
