Buying criteria
What makes the cut.
The shortlist is intentionally smaller than the market. A tool belongs here only when its reviewed workflow overlaps the decision on this page.
- 1
Workflow fit
The tool has to solve the named job in a real outbound workflow, not merely mention it on a feature page.
- 2
Operator cost
We weigh setup, maintenance, credits, seats, and handoffs alongside the headline subscription price.
- 3
Evidence quality
Pricing and product claims come from the reviewed records and carry visible caveats when evidence is incomplete.
