Eesier's prospecting agent vs Mailshake
Mailshake is a classic cold-outreach tool (email + LinkedIn) operated by human SDRs. The prospecting agent is the standalone autonomous AI SDR with database, AI, and WhatsApp built in.
Mailshake is a US cold-outreach platform combining email sequences + LinkedIn, designed for human SDRs running cadences. The prospecting agent is a full autonomous AI SDR — built-in 60M+ company database, AI that writes every message, conversational qualification, native WhatsApp channel — at $497/month flat.
What's the difference between the prospecting agent and Mailshake?
Mailshake sends emails (and InMails). Human SDR writes, monitors, qualifies. The prospecting agent eliminates the SDR — agent does it all.

Operated tool vs autonomous agent
Mailshake is the truck. The prospecting agent is the truck + driver. Same problem, different layers of solution.
Teams with senior SDRs already in place can use Mailshake as their toolkit. Teams without (or wanting to avoid) human SDRs solve it directly with eesier.
Total cost
Mailshake USD 59-99/user + SDR + data: USD 2-4K/month. The prospecting agent: $497/month total.
Mailshake wins on isolated license price. The prospecting agent wins on cost-per-qualified-meeting generated.
Combining Mailshake and the prospecting agent
Rarely useful — both solve the same layer. Edge case: international operation with Mailshake in US and the prospecting agent in LATAM/Brazil.
For single-market teams, the prospecting agent alone solves it.
