Outreach Cold Email Deliverability
Overview
Instantly is a cold-email platform built for volume, with unlimited mailbox connections, automated warmup, and deliverability monitoring. Funds running systematic outbound sourcing — hundreds of personalized emails a week to founders surfaced by their signal stack — use it as the sending layer that keeps messages out of spam folders. It pairs naturally with Clay or a data provider upstream, since it brings sending infrastructure rather than a contact database of its own.
