Pros & Cons
Instantly.ai
Pros
- Unlimited email accounts and warmup included in all sending plans — no per-account fees
- Built-in B2B lead database with 450M+ contacts and multi-provider email enrichment
- Done-for-you domain and email account setup with DNS records pre-configured
- AI-powered personalization, A/Z testing, and automated campaign optimization
- CRM plans include unlimited seats, making it cost-effective for larger teams
Cons
- Pricing is split across three separate products (Sending, Leads, CRM) — full functionality requires multiple subscriptions
- Entry-level sending plan limits contacts to 1,000 and emails to 5,000/month, which is restrictive for active outreach
- Primarily focused on email outreach — multi-channel capabilities (calling, SMS) are limited to higher CRM tiers
- Credit-based lead database pricing can be confusing with variable ranges (e.g., 1,500-2,000 credits)
PhantomBuster
Pros
- Pre-built automations (Phantoms) for LinkedIn require zero coding to set up
- Cloud-based execution means automations run without keeping your browser open
- Built-in email enrichment adds verified email addresses to scraped leads
- Supports multi-step automation workflows (Flows) for complex sequences
Cons
- Aggressive LinkedIn automation may risk account restrictions if usage limits aren't carefully managed
- Pricing can be expensive for solo users relative to simpler scraping tools
- Heavily LinkedIn-focused; other social platform support is more limited
Our Verdict
Both Instantly.ai and PhantomBuster are excellent choices with similar feature sets. Your decision should depend on your specific needs, pricing, and whether you need self-hosting capabilities.
