"Our reply rates went from 2% to 47% in the first month. Kessora AI's research on each prospect is unreal. Every email feels hand-written by someone who actually knows the recipient."

The Deep Dive
Why Teams Leave Instantly.ai
Three architectural differences that make Kessora AI fundamentally different from Instantly.ai.
01
The EdgeSame price range, but Kessora AI does 4x more. Warmup alone doesn't fill your pipeline.
Warmup vs Complete SDR
Instantly.ai
Instantly's core product is email warmup. Great at deliverability, but that's all it does.
Kessora AI
Kessora AI includes smart warmup AND finds leads, writes AI emails, manages follow-ups, classifies replies.
02
The EdgeFinding leads is half the work. Instantly skips it; Kessora AI automates it.
You Bring Leads vs AI Finds Leads
Instantly.ai
Instantly sends emails to lists you provide. No list = tool does nothing.
Kessora AI
Tell the AI your ICP. It finds matching leads and verifies contact info automatically.
03
The EdgeAI-personalized emails get 2-3x higher reply rates than template-based outreach.
Your Copy vs AI-Generated
Instantly.ai
You write every template. Merge tags add basic personalization. Same email, different name.
Kessora AI
AI researches each lead and writes a unique email. No templates. No merge tags. Genuinely personal.

FAQ
Common Questions
Does Kessora AI handle email warmup?
Yes. Kessora AI includes smart sending with automatic warmup. Instantly's network is larger, but Kessora AI's warmup works great for typical SMB volumes (100-2,000 emails/month).
Can I switch from Instantly easily?
Yes. Export your lists as CSV, import into Kessora AI, describe your ICP. The AI enriches existing lists and builds new ones. No need to migrate sequences.
Is deliverability as good as Instantly?
For typical outreach volumes, yes. If you're sending 10,000+ emails/day from new domains, Instantly's warmup network has an edge. For SMB outreach, Kessora AI's deliverability is excellent.
