Instantly is a cold email platform built for volume. It offers unlimited email accounts, unlimited warm-up, a unified inbox, and an AI reply agent, and it sells a B2B lead database and a CRM separately. Outreach plans are priced by monthly emails and uploaded contacts rather than by user.
Agencies use it for lead generation at scale where many sending accounts matter. This review covers the plans, the missing detail, and the fit.
| Detail | Summary |
|---|---|
| Best for | Small teams to large agencies |

How much does Instantly cost for agencies in 2026?
On monthly billing, Growth costs $47 a month, Hypergrowth costs $97, and Light Speed costs $358. Annual billing shows about 20 percent lower prices at $37.60, $77.60, and $286.30 a month.
Growth covers 1,000 uploaded contacts and 5,000 emails a month with chat support. Hypergrowth covers 25,000 contacts and 125,000 emails with premium live support. Light Speed covers 100,000 contacts and 500,000 emails and adds a private deliverability network. All three list unlimited email accounts.
The leads database and CRM are priced separately, so an agency that uses all three should add those costs. Because plans are not per user, cost follows your sending volume, which suits agencies with large lists and small teams.
| Plan | Price | What stands out |
|---|---|---|
| Growth | $37.60 per month (annual billing); $47 monthly | Unlimited email accounts, 1,000 uploaded contacts, 5,000 emails a month, chat support |
| Hypergrowth | $77.60 per month (annual billing); $97 monthly | Unlimited email accounts, 25,000 uploaded contacts, 125,000 emails a month, premium live support |
| Light Speed | $286.30 per month (annual billing); $358 monthly | 100,000 uploaded contacts, 500,000 emails a month, private deliverability network |
Is Instantly good for agency lead generation?
Yes for volume. Unlimited email accounts and warm-up let you spread sending across many inboxes, and it has the highest G2 score in this group at 91 percent five-star reviews. One reviewer says the product under-delivered after switching, so test with a pilot.
Client workspaces, team roles, and white-labeling were not stated, so confirm how you will separate clients before you scale.
High-volume cold email carries risk. Keep lists clean, use dedicated domains, and follow the laws that apply to your clients, since poor practice harms deliverability for everyone on the domain.
A sensible pattern for agencies is to give each client a small set of dedicated domains and inboxes, warm them for a few weeks, and ramp volume slowly. Unlimited accounts make that easy to set up but do not remove the need for careful list quality.
Track reply rate, bounce rate, and spam complaints weekly, and pause a campaign at the first sign of trouble. The tool can send a great deal, but your sender reputation is the real asset.
What could we not confirm for Instantly?
Its security page returned an error, so SOC 2, ISO 27001, GDPR, SSO, and two-factor authentication were not stated. Integration counts and mobile apps were not stated either.
Support is chat on Growth and premium live support on Hypergrowth, with hours not stated. Ask for security documents before you handle client data.
Check the contract terms for how the plan counts contacts and emails, and what happens when you reach a limit mid-month, since overage rules affect cost for agencies with spiky campaigns.
Also test the unified inbox with a real client campaign. Handling replies across many inboxes is where agencies spend time, so the quality of that view matters as much as the sending features.
What integrations, security, and support does Instantly offer?
Features beyond price decide whether a tool fits your agency stack and your clients' security questions. This is what Instantly states publicly, as checked in October 2026.
| Area | What Instantly offers |
|---|---|
| Integrations | API, webhooks and integrations are listed; a count was not stated |
| Security | Security and compliance details were not stated (the security page returned an error) |
| Support | Growth: chat support; Hypergrowth: premium live support; hours were not stated |
| Apps | Mobile apps were not stated |
