About Instantly.

Instantly is a popular cold email tool focused on sending volume and deliverability. It gained rapid adoption by offering unlimited email account connections at a flat monthly rate, making it appealing to high-volume senders and agencies.

The platform includes a warmup network where users' accounts warm each other up, a campaign builder with A/B testing, and a unified inbox (Unibox) for managing replies. Instantly also offers a lead database add-on for finding prospects.
