Customer.io
Best for: Product and growth teams that want signup, activation, feature use, account, or subscription events to determine the next message. Its value depends on trustworthy instrumentation and identity resolution.

| Pilot | Pass evidence |
|---|---|
| Instrument three real product events and run one activation journey with identity and conversion exits. | Events enroll the right person once, late or duplicate events behave correctly, and product outcome reporting is usable. |
ActiveCampaign
Best for: Businesses that need email to respond to lead score, owner, pipeline stage, meetings, and detailed conditions without adopting a full data-first engagement layer.
Pros, cons, and pricing: Pros include mature branching, goals, scoring, CRM handoffs, and a familiar campaign workflow. Cons include governance effort and contact- or feature-based cost growth. Check current terms on the official ActiveCampaign pricing page.
| Pilot | Pass evidence |
|---|---|
| Run one nurture path with a score threshold, owner change, meeting exit, and unsubscribe. | Branches are observable, handoffs stop promotion, and the team can report the intended outcome. |
| Fair-pilot question | Customer.io evidence | ActiveCampaign evidence |
|---|---|---|
| Can the trigger be explained? | Event, profile, identity, timestamp, and data-source history | Score, field, owner, goal, and CRM history |
| Can the journey stop safely? | Conversion, consent, identity, and message exits | Goal, meeting, owner, and unsubscribe exits |
| Can the team operate it? | Event owner, data pipeline, QA, retention, and cost model | Automation owner, seats, contacts, reporting, and rollback |
