High-volume cold email infrastructure with warmup, sequences and a B2B lead database

## About Instantly.ai

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.

## Platform details

- Pricing: Growth from $37/mo, Hypergrowth $97/mo, with higher volume tiers above. Leads, CRM and deliverability add-ons are priced separately, so a working setup commonly lands between $150 and $400/mo. 14-day free trial, no card required.
- Founded: 2021, by Nils Schneider and Raul Kaevand
- Funding: Bootstrapped, no outside funding. Estimated $38.2M ARR in 2026
- Last reviewed: 2026-08-17

## What is Instantly.ai good at?

Deliverability. That is the honest answer and it is not a small thing. Instantly lets you connect effectively unlimited sending accounts, rotates sends across them, warms them continuously and gives you the reply management to handle what comes back. For anyone sending serious outbound volume, that infrastructure is the product. It also bundles the pieces around sending: a B2B lead database so you are not paying a separate data vendor, multi-step sequences, and a unified inbox so replies across dozens of mailboxes land in one place. The company is bootstrapped and profitable at roughly $38M ARR, which shows in the product: it is unglamorous, focused and built by people who clearly send email themselves.

## What does Instantly.ai actually cost?

The advertised entry is $37 a month for Growth, and $97 for Hypergrowth. Those numbers are real but incomplete. Leads, CRM and deliverability features are separately priced, so most working setups land somewhere between $150 and $400 a month once you have the pieces you need. That is still good value if outbound is your growth engine and volume is high. It is poor value if you send fifty thoughtful emails a month, because you are paying for infrastructure built to survive tens of thousands. There is a 14-day trial with no card, which is the right way to find out which of those two you are.

## Where a workforce platform fits differently

Instantly stops at the reply. Somebody still has to read it, decide what it means, book the call, prep for the call, update the CRM, chase the ones who went quiet and tell you what is working. In most small teams that somebody is the founder, at eleven at night. Sistava puts an employee on each of those steps. The SDR does the outreach, a support or ops employee handles the inbound thread, an analyst reports on conversion, and a leader keeps the sprint honest. All of them share memory, so the follow-up is not asking a question the prospect already answered. The two are not mutually exclusive. Plenty of teams should run Instantly for sending infrastructure and a workforce for everything either side of it.
