Instantly

Instantly is one of the most popular cold email platforms, built around a simple idea: connect as many sending accounts as you like without paying per inbox. Every plan includes unlimited email accounts and unlimited warm-up, so agencies and sales teams can spread volume across many inboxes and protect deliverability.

Campaigns support multi-step sequences, inbox rotation and scheduling, and replies from every account land in one place in the Unibox. Instantly has added AI across the product, including an AI sales agent and a reply agent, plus a built-in CRM. Its lead database, SuperSearch, gives access to more than 450 million B2B contacts on credit-based plans, so you can build lists and send from the same tool. The top Lightspeed plan adds dedicated sending servers and IP rotation for high volume.

It suits agencies, founders and sales teams running cold email at scale who want sending, warm-up and lead data in one place.

The Growth plan costs $47 a month, or $37.60 billed yearly, for 5,000 emails and 1,000 uploaded contacts. Hypergrowth is $97 a month for 125,000 emails and 25,000 contacts, and Lightspeed is $358 a month for 500,000 emails. Enterprise is custom.
