Walk away from Avina if

- Walk away if your workflow cannot tolerate credit consumption on high-traffic web domains: Because enrichment and AI account research consume monthly platform credits, organizations with high-volume anonymous web traffic can exhaust Starter credit pools rapidly without strict ICP domain filtering.
- Walk away if downstream sequencer dependency is a deal-breaker for your team: Avina focuses on signal unification, account scoring, and draft generation rather than operating as a standalone email infrastructure or dialer provider, requiring connection to Outreach, Salesloft, or Apollo.
