Instantly
Cold email outreach with built-in deliverability and warmup
Overview
Instantly is a cold email platform built around inbox health and deliverability. It bundles unlimited email accounts on every paid plan, automated warmup powered by a network of 200,000+ accounts, an AI copy assistant, and a unified inbox so outbound teams can scale sending without burning their domains. Where most cold-email tools treat deliverability as an afterthought, Instantly makes it the centerpiece — the warmup network is the largest in the industry, and inbox placement is meaningfully better than Apollo's built-in sequencer.
The platform also includes a B2B lead database of 160M+ contacts, so teams can source prospects and run sequences from a single workspace instead of paying for ZoomInfo separately. Pricing starts at $37/month for Growth and most agencies running real volume land on the Hypergrowth tier at $97/month — significantly cheaper per active sequence than Outreach or Salesloft. The trade-off vs.
Smartlead is UI polish: Smartlead is more API-first and developer-friendly, while Instantly is the faster path to value for marketing-led teams. For founders and agencies running cold outbound at any meaningful scale who refuse to compromise on deliverability, Instantly is the default.
