Why Scavio Wins
- The OP read that Instantly 'might not be the greatest' but didn't test alternatives. Smartlead Basic at $39/mo is a quieter, less add-on-heavy alternative for hyper-niched agencies.
- The differentiator at the niche-agency scale isn't the sender — it's per-prospect personalization. Scavio research at $0.005-0.02 per prospect makes hyper-niched openings feasible.
- Module bloat is real on Instantly. The advertised $30-47/mo Growth tier rarely captures actual spend once Credits, CRM, Inbox Placement, and Pre-Warmed Accounts add-ons are included.
- Honest case for Instantly: the integrated B2B contact database (lead-gen plan from $37.90/mo) is genuinely useful when the agency doesn't have its own list.
- Per-month at scale: 1,000 prospects × $0.01 research = $10 Scavio + $39 Smartlead + base Scavio plan = ~$80 total. Sustainable for hyper-niched outbound.
