Instantly

Instantly is cold email software for agencies and outbound sales teams, with unlimited sending accounts on volume-priced plans and lead data paid in credits.

Instantly runs cold email campaigns across many connected mailboxes at once, so a team can reach new prospects at volume while each sending account stays under its own daily cap. It is built and sold by Instantly, an independent, bootstrapped company of the same name. Sending is one part of the work. The same account warms up new mailboxes, finds leads, sorts replies and moves interested prospects into a pipeline. Campaigns are sequences of email steps with wait days between them and an option to stop when a lead replies. A/Z testing compares several versions of a step and can pick the winner by reply, click or open rate. Email warmup raises volume gradually through Slow Ramp, and sender rotation spreads each campaign across the connected accounts. Replies land in Unibox, where AI Custom Reply Labels sort them and the AI Reply Agent answers in Human-In-The-Loop or Autopilot mode. SuperSearch searches a B2B lead database, Copilot and the AI Sequence Writer draft the emails, and the built-in CRM adds calls, SMS and tasks through Salesflows. The platform suits agencies that run outbound for several clients, founders who prospect for themselves and small sales teams sending from many mailboxes. Every Outreach plan connects unlimited email accounts, so the subscription is priced by monthly email volume and uploaded contacts. Lead searches, enrichment and AI replies draw on Instantly Credits, a separate subscription that can be bundled with Outreach. The CRM and Website Visitors are their own subscriptions on the same login, and the trial needs no card. A typical campaign starts in SuperSearch with a list filtered by technology or funding news, then sends from mailboxes that have finished warming up. Website Visitors can feed a campaign too, enrolling visitors to the customer's site as soon as they are identified. Interested replies are labelled in Unibox, then answered by the reply agent or picked up by a rep. Campaign events reach HubSpot or Salesforce through OutboundSync, and native webhooks carry them to other systems. Instantly fits teams whose pipeline depends on cold email, with calls and SMS joining through the CRM once outbound grows past the inbox.
