Instantly

Instantly is built for outbound sales by email at volume. Users connect many sending mailboxes, warm them up automatically to protect deliverability, and run campaigns of personalized sequences that rotate across those accounts. Replies land in one inbox, and a simple CRM tracks leads and deals. The suite also includes a B2B lead database with email verification, website visitor identification, and deliverability tools such as inbox placement tests. AI agents can build campaigns and answer incoming replies. It is used by sales teams, founders and lead generation agencies that rely on cold email to book meetings.
