What is Instantly?
Instantly has become the go-to cold email platform for outbound-focused teams, agencies, and individual SDRs who prioritize email volume and deliverability over multi-channel complexity. Founded in 2021, it quickly gained traction by solving the core pain point of cold email: managing multiple sending accounts without getting flagged as spam.
The platform's core promise is simple: send more cold emails that actually land in inboxes. They accomplish this through unlimited email account connections, built-in warmup, and deliverability monitoring-features that used to require cobbling together multiple tools.
Pricing Breakdown
Instantly offers two main product lines: the core sending platform and a separate lead database (Supersearch). This separation catches some buyers off guard.

Who Should Use Instantly?
Our Verdict
Instantly is the best pure cold email tool on the market. If your outbound motion is email-first and you're sending at scale, it's hard to beat the value. The unlimited accounts and built-in warmup eliminate the need for multiple subscriptions.
Ideal for:
- Lead gen agencies managing multiple client campaigns
- SDR teams focused on high-volume email outreach
- Founders doing cold email without a big budget
- Teams already using another tool for leads (Apollo, ZoomInfo)
Look elsewhere if:
- You need phone and LinkedIn in the same platform
- You want an all-in-one with built-in lead database
- You require deep CRM integrations (Salesforce workflows)
- Your team needs advanced analytics and reporting
Getting Started
Instantly offers a 14-day free trial with access to most features. The setup process is straightforward:
- Connect your email accounts (Google Workspace or Outlook recommended)
- Enable warmup for new domains (run for 2-3 weeks before sending)
- Import or build your lead list
- Create your first sequence with 3-5 touch points
- Start with low volume (50-100/day per account) and scale up
The learning curve is minimal compared to more complex platforms. Most teams are up and running within a day.
