What is Mailshake?
Mailshake's per-seat price is friendly for small teams and the SHAKEspeare AI tools cover the basics for templated outbound.
How is IntelSDR different from Mailshake?
- Mailshake's AI tools are general-purpose. IntelSDR's prompt is built specifically for the 4-sentence outbound first line.

- Bring-your-own OpenAI key, $49/mo flat for one seat.
When IntelSDR is the right pick
