Instantly.ai
High-volume cold-email and outbound-sales platform with AI reply agents, warmup, and a lead database.

What you can produce with Instantly.ai
- Unlimited sending accounts priced by send volume rather than per seat
- Built-in warmup, an AI reply layer and a lead database in a single platform
- A high-volume outbound engine that thousands of G2 reviewers rate at 4.8–4.9
- ⚠️ Warmup metrics you should not treat as proof of delivery. Reviewers and Reddit threads describe heat scores reading 90-plus in the dashboard while live campaigns still land 30–40% in spam, with no deep diagnostics or root-cause alerts to explain the gap — the platform's own number is not evidence your mail reached an inbox
- ⚠️ The risk that comes with the model: the same volume-first approach that draws users invites exactly the deliverability and inbox-placement problems aggressive cold email creates
- Support that reviewers describe as AI-bot-gated and slow, plus billing friction including reported double charges and buggy done-for-you domain setups — Trustpilot sits around 4.5 with a visible cluster of one-star complaints
What this is for: Running high-volume outbound email campaigns with unlimited sending accounts, deliverability warmup, AI reply handling, and lead sourcing.
Who this is for: Sales teams, lead-gen agencies, and founders who send cold outbound at scale.
Availability: Commercial subscription priced by sending volume, with a free trial; no permanent free tier.
What people say
Instantly's reviews are plentiful and polarized. Its G2 rating is high, 4.8 out of 5 across more than 4,100 reviews. Users love the volume-based model, which gives them unlimited sending accounts, built-in warmup, an AI reply layer, and a lead database, all priced by send volume instead of seats. Trustpilot currently hides Instantly's rating for a breach of its guidelines and says it removed a number of fake reviews; of the 1,162 still listed, 67% are five-star and 25% one-star.
The dominant complaint is deliverability, and it's a substantive one for a cold-email tool. Multiple reviewers and Reddit threads describe warmup "heat scores" reading 90-plus inside the dashboard while live campaigns still land 30-40% in spam, with no deep diagnostics or root-cause alerts to explain the gap. Secondary complaints center on support that feels AI-bot-gated and slow, plus billing friction including reports of double charges and buggy done-for-you domain setups.
The fair read: Instantly is a capable, popular high-volume outbound platform, but the same volume-first approach that draws users also invites the deliverability and inbox-placement risks that come with aggressive cold email — and the platform's own warmup metrics shouldn't be trusted as proof your mail is actually reaching inboxes.
Outreach plans start at $47 a month for Growth, with 5,000 emails and 1,000 uploaded contacts, then Hypergrowth at $97 for 125,000 emails and Light Speed at $358 for 500,000, with annual billing about 20% cheaper; its lead database claims more than 450 million B2B contacts. Instantly's own guidance is 30 campaign emails per account per day, ramped up by two a day. Since May 2026 it also sells AirMail, its own sending mailboxes, at $4 an inbox on .com and .org domains.
Developers get a documented API v2 with an official TypeScript SDK, a CLI and an MCP server.
