Instantly.ai vs Sistava
Instantly.ai is cold email infrastructure built for volume: connect unlimited sending accounts, rotate across them, warm them up, run multi-step sequences, manage replies in a unified inbox and pull prospects from a built-in B2B database. Bootstrapped since 2021 and around $38M ARR, it is one of the most widely used outbound tools among agencies. Sistava is not a sending platform. It is a workforce where the SDR is one employee among several, and the work continues after the reply arrives.

Why Sistava
- Sistava covers the whole funnel with one team: an SDR sends, a support employee handles the reply, an analyst reports on it. Instantly covers sending and reply management.
- Sistava employees carry layered memory, so the follow-up knows what the last call covered and what the customer already said no to. Instantly personalises from list data and sequence variables.
- Sistava reaches thousands of apps plus custom MCP servers, so outbound is one capability among many. Instantly is purpose-built for email and its own lead database.
- Sistava runs on Temporal with an execution inspector, so a long campaign survives a restart and every step is auditable. Instantly reports at campaign and deliverability level.
- Sistava prices as a flat plan covering the whole workforce. Instantly stacks add-ons for leads, CRM and deliverability on top of the base plan.
