Instantly pricing (2026)
| Plan | Price | Emails / mo | Leads |
|---|---|---|---|
| Growth | $47/mo | 5,000 | 1,000 |
| Hypergrowth | $97/mo | 125,000 | 25,000 |
| Lightspeed | $358/mo | 500,000+ | 100,000 |

Lead credits are a separate add-on (Growth Credits $47/mo for 1,500; Supersonic $197/mo for 5,000). A fully loaded setup with leads and CRM typically runs $150–$400/mo. Annual billing saves ~15%. A 14-day free trial needs no credit card; there is no permanent free plan.
Pros and cons
Pros
- Unlimited inbox connections on every plan — the killer feature for agencies.
- Growth at $47/mo is the cheapest credible cold-email entry point.
- Warmup network is among the most robust in the industry.
Cons
- SuperSearch lead database is a separate paid add-on that inflates real cost.
- Email-only — no built-in dialer or LinkedIn automation.
- CRM and deal management are lighter than dedicated sales-engagement platforms.
Who should use Instantly
Instantly is for teams sending serious volume across many domains. If you are still assembling the lead lists it sends, Clay builds and enriches them first. Solo founders can start on Growth; agencies usually land on Hypergrowth once they outgrow the 5,000-email cap.
Verdict: 4.4/5. The best cold-email platform for high-volume agencies, with unlimited inboxes that no seat-based competitor can match on price.
