Instantly is a sales engagement platform for cold email outreach, that is, unsolicited sales emails to businesses that have not asked to be contacted. It combines a sending tool with a B2B lead database, email deliverability tools and a CRM (customer relationship management system, a database of leads and deals).
A user connects any number of sending email accounts and builds a campaign: a list of leads and a sequence of emails and follow-ups, which AI can write and personalize. Campaigns send from the connected accounts, can include LinkedIn and webhook steps, and collects replies in a unified inbox called Unibox. Its warmup tool protects deliverability (the share of emails that reach the inbox instead of spam): it exchanges warmup emails with a pool of more than a million real email accounts, starting with 2 emails a day and ramping up slowly, and a dashboard shows how many emails land in inbox or spam. The Lead Finder searches more than 450 million B2B contacts.
It is a hosted subscription service, priced by emails sent and contacts uploaded per month, with credits for lead data sold separately or in bundles.
