Instantly

Cold email at scale — unlimited sending accounts, built-in warm-up, and a B2B lead database in one.

What is Instantly?

Instantly is the volume player in cold outreach: connect unlimited sending accounts on any plan, rotate sends across them, and let the built-in warm-up network keep deliverability healthy — the economics that made it the default for agencies running serious outbound. Campaigns support sequences, A/B tests, and AI-assisted personalization, while the unified inbox (Unibox) consolidates replies from every mailbox for one team workflow. Instantly has expanded into a full outbound stack: a B2B lead database with verified contacts, CRM-style deal tracking, and website visitor identification. Deliverability tooling — inbox placement tests, domain health checks, provider matching — is woven throughout. If your strategy is many domains, many inboxes, and high daily volume, Instantly is built precisely for that shape of work.
