Cold email at volume, with the deliverability infrastructure that makes volume survivable.
Pricing
Verified 14 Jul 2026· sourceOverview
Instantly is built for one job: sending a lot of cold email without your domains being incinerated. The architecture reflects that — unlimited connected sending accounts so volume spreads thinly across many mailboxes, automated warmup to build sender reputation, and a unified inbox so replies from dozens of mailboxes land in one place. Alongside the sending engine sits a large B2B lead database and enrichment, plus AI agents for drafting and reply handling, so the list-building and sending halves live in one tool. Judged as an outbound machine, it is one of the strongest options available. Judge it on everything else and be honest. There is no free tier — the bundled plans start at a level that is a real commitment for a solo founder, and the useful lead credits sit in tiers well above the entry point. It solves deliverability mechanics, not deliverability ethics: a bad list and generic AI copy will still get you spam-flagged, and cold outreach carries genuine compliance exposure under GDPR and similar regimes. The tool is not the strategy.
