The Verdict
“Instantly is the #1 cold email tool for agencies and founders who need to scale outbound. Unlimited accounts and warmup at $30/mo is unbeatable value. The main limitation is it's email-only — pair with HeyReach for LinkedIn.”
Best For
SDR teams doing 500+ cold emails/day who don't need multichannel — the best pure cold email tool at any price point
Not Great For
Enterprise teams needing CRM-native integrations, compliance audit trails, and multichannel sequences — Outreach or Salesloft are better fits
