Quick answer
What is Instantly, and is it worth paying for?
Instantly is a cold email platform: you connect as many sending mailboxes as you like, warm them up through its network, upload or find leads, and run multi-step email campaigns with replies collected in one inbox (Unibox). Leads (SuperSearch credits), a CRM, website visitor identification, inbox placement tests and done-for-you mailboxes are separate products with separate bills. It's worth paying for if you send cold email at volume, run outbound for clients, and will follow deliverability and anti-spam rules. Outreach plans start at $37.60 a month billed annually ($47 monthly) for 1,000 uploaded contacts and 5,000 emails a month, checked on Instantly's pricing page on October 13, 2026. Fees are non-refundable under its terms.
- Best for
- Lead-generation agencies and outbound teams sending from many domains and mailboxes who need warmup, rotation and a shared reply inbox.
- Skip it if
- You need a few hundred personalized emails a month, or one tool for data, sequences and dialing; Apollo covers that with a free plan.
- Strongest capability
- Sending infrastructure: unlimited email accounts on every paid plan, warmup, inbox rotation, bounce protection and a deliverability agent, plus optional pre-warmed mailboxes.
- Biggest limitation
- Billing complexity and terms: Outreach, credits, CRM and inbox tests are billed separately, team seats and Unibox replies need Hypergrowth, and all fees are non-refundable.
The Verdict
Instantly is built for one thing above all: sending a lot of cold email without burning your domains. Every paid Outreach plan allows unlimited email accounts with warmup, and the platform adds inbox rotation, auto-pause on high bounce rates, a deliverability agent (June 2026) and pre-warmed or done-for-you mailboxes. Its SuperSearch lead database, which Instantly puts at 450 million contacts, runs on a separate credit plan, as do its AI reply and sales agents. The 2026 releases added a Copilot that builds automations, new agent types and a redesigned app. The weaknesses are commercial. The cheapest plan, Growth, can't reply from Unibox, invite teammates or use webhooks; those start at Hypergrowth ($77.60 a month billed annually). Separate subscriptions make the real cost harder to see, Instantly's own pages disagree on several prices and limits, and its terms make every fee non-refundable. We score Instantly 8.3/10.
Best for
Agencies and outbound teams that send cold email at volume and want warmup, rotation and a shared inbox in one place.
Skip if
You send low volumes, want data and sequences in one subscription, or need clear, refundable billing.

The Background
What Is Instantly?
Instantly (instantly.ai, operated by Foo Monk, LLC under its terms of service) is a cold email platform. Its core Outreach product connects unlimited sending accounts, warms them up, rotates sending across them and runs campaigns, with replies gathered in Unibox. Around it Instantly sells separately billed products: Instantly Credits for SuperSearch lead data, enrichment, verification and AI agents; a CRM with email, calls, SMS and tasks; Website Visitors, which identifies US visitors to your site; Inbox Placement tests; and done-for-you, AirMail and pre-warmed mailboxes and domains. Automations and a Copilot assistant are included with Outreach plans. Instantly says 50,000+ sales teams use it (other pages say 40,000+); those are its own figures.
The Product
Instantly Features: What You Actually Get
Unlimited sending accounts and warmup
Every paid Outreach plan connects unlimited email accounts with unlimited warmup, though Instantly's plan comparison caps how many SMTP accounts join its standard warmup pool (100 on Growth, 500 on Hypergrowth, 1,000 on Light Speed). Instantly says its warmup network has over 1 million real email accounts, made up of other Instantly users; that's its own claim. Light Speed adds server and IP sharding and rotation (SISR).
An agency connects 40 mailboxes across 10 domains for a new client, warms them for three weeks and then spreads the campaign across all of them.
Campaigns, Unibox and testing
Campaigns run multi-step sequences with A/Z testing (basic on Growth, up to 26 variants from Hypergrowth), subsequences and scheduling. Unibox collects replies from every mailbox; Growth can only preview replies there, while Hypergrowth and above can reply. Instantly's guidance is about 30 campaign emails a day per account, keeping bounces under 2%, and campaigns auto-pause at a 5% bounce rate by default.
An SDR runs two subject-line variants across 20 mailboxes at 30 emails a day each and answers positive replies from Unibox.
SuperSearch leads and AI agents (Credits)
Instantly Credits are a separate subscription, from $9 a month for 150 credits to $1,700 for 200,000. A work email costs 1 or 2 credits (none if not found), an enriched profile 0.5, verification 0.25, and AI Reply Agent or AI Sales Agent actions 5 credits each. Credits on monthly plans expire after two months, according to Instantly's credit article.
A founder buys the Growth credit plan (1,500 credits for $47 a month), finds 1,000 verified work emails for a target industry and loads them into a campaign.
Deliverability tools
Inbox Placement tests check whether emails land in the inbox or spam and verify SPF, DKIM and DMARC; it's a separate $47 or $97 monthly subscription, with two free tests to start. The Deliverability AI Agent comes with Hypergrowth and above. Done-for-you Google mailboxes cost $5 a month, pre-warmed ones $10, AirMail accounts $4 and domains $15 a year; Instantly's terms say you get access rights, not ownership, of these domains and mailboxes.
A team runs an inbox placement test before a launch, finds Outlook placement is poor, and shifts volume to better-performing domains.
Automations, Copilot, API and MCP
Automations, a visual trigger-and-action builder, are included on all Outreach plans, and since July 2026 Copilot can build them from plain language. API v2 (January 2025) is available from Growth, webhooks from Hypergrowth, and a hosted MCP server exposes the API to AI assistants at no extra cost for accounts with API access.
An operations lead has Copilot create an automation that sends interested replies to HubSpot and posts them in Slack.
Feature recap
- Unlimited email accounts and warmup on every paid Outreach plan
- Multi-step campaigns, A/Z testing, subsequences and Unibox
- SuperSearch lead database and AI agents on separate credit plans
- Inbox placement tests, deliverability agent and done-for-you mailboxes
- Automations and Copilot included with Outreach

The Numbers
Instantly Pricing: Every Plan Explained
Instantly bills each product separately: Outreach, Credits, CRM, Inbox Placement and mailboxes. The Outreach prices below are from Instantly's pricing page, checked October 13, 2026, in USD; annual prices are shown as a monthly figure. Uploaded-contact limits are totals across all campaigns and don't reset monthly.
| Plan | Monthly | Annual | Included Features | Best For |
|---|---|---|---|---|
| Outreach Growth | $47/mo | $37.60/mo | 1,000 uploaded contacts, 5,000 emails a month, unlimited email accounts and warmup, basic A/Z testing, API and Zapier; no Unibox replies, team invites, webhooks or extra workspaces | Solo senders starting out |
| Outreach HypergrowthBest value | $97/mo | $77.60/mo | 25,000 contacts, 125,000 emails a month, Unibox replies, team members and workspaces, webhooks and Slack, subsequences, Deliverability AI Agent, priority support | Teams and agencies |
| Outreach Light Speed | $358/mo | $286.30/mo | 100,000 contacts, 500,000 emails a month, everything in Hypergrowth plus SISR server and IP rotation | High-volume agencies |
| Credits (leads and AI) | From $9/mo (150 credits) | 10% off, all credits up front | SuperSearch emails (1-2 credits each), enrichment, verification, AI Reply and Sales Agents (5 credits per action), Website Visitors (3 credits per resolved profile). Growth credits $47 for 1,500 | Teams that need lead data |
| Other products | CRM $47 or $97; Inbox Placement $47 or $97 | — | CRM with email, calls, SMS and tasks; Inbox Placement tests; DFY mailboxes $5/mo, pre-warmed $10/mo, AirMail $4/mo, domains $15/yr; Enterprise and VIP done-for-you service quoted | Add as needed |
The real cost depends on which products you stack. A team on Hypergrowth billed annually ($77.60) with Growth credits ($47 monthly) and five done-for-you mailboxes ($25) spends about $150 a month before domains, and more if it adds the CRM or Inbox Placement (our arithmetic from Instantly's listed prices). Bundles combine Outreach and Credits: Starter $94, Scale $194 and Agency $555 a month, or 10% less billed annually. Instantly's terms (updated September 22, 2026) say all fees are non-refundable and non-cancellable, unused fees for a started month or year aren't refunded even pro rata, and you can't re-subscribe to the same monthly plan within 21 days. The 14-day free trial needs no card and doesn't convert automatically; it includes 2 email accounts, 250 leads, 1,000 emails and 100 credits, and the account is deleted after it expires.
Rules
Cold email compliance and Instantly's sending policy
Instantly's terms make you, the subscriber, the sender and initiator under the US CAN-SPAM Act, including for messages its AI agents send for you, and the data controller under EU and UK GDPR, so you need a lawful basis for contacting people. Its sending policy (updated July 28, 2026) requires an unsubscribe link in every campaign, opt-outs honored immediately, sender details that identify you and domains at least a month old, and it refuses senders in categories such as gambling, adult content, payday loans and lead resale.
Instantly can rate-limit or suspend accounts at its discretion under that policy. Website Visitors requires a privacy-policy update and a cookie banner on your site. None of this is legal advice; check the rules in each country you email.
Read before you buy
Where Instantly's own pages differ
Prices and limits: the pricing page's feature table lists Hypergrowth at 100,000 emails a month while its plan card, the help center and the machine-readable pricing page say 125,000, and the bundle breakdown on the same page prices Hypergrowth at $358 and Supersonic credits at $197 instead of $97 each.
CRM price: the plans overview lists Growth CRM at $47 and Hyper CRM at $97, while the CRM help article describes a flat $97 a month.
Overages and credits: the machine-readable pricing page says you upgrade tiers rather than pay overage, while the terms say overage is invoiced in arrears. The credit article says monthly credits expire after two months; the terms say credits expire at the end of the period and may roll over twice.
Cancellation: the terms require 30 days' written notice before the end of a term in one section and allow cancelling anytime in settings, effective at period end, in another.
The Tradeoffs
Instantly Pros and Cons
What we love
- Unlimited email accounts and warmup on every paid plan
- Inbox rotation, bounce auto-pause and a deliverability agent
- Built-in lead database and AI agents on one credit pool
- Automations and Copilot included; API from the Growth plan
- Done-for-you and pre-warmed mailboxes for fast setup
- 14-day trial with no card and no automatic charge
What could be better
- Products and credits are billed separately, so totals add up
- Growth can't reply from Unibox or invite teammates
- All fees are non-refundable under Instantly's terms
- Native Salesforce integration not documented (help center routes it through a third-party tool)
- Instantly's pages contradict each other on several prices and limits
- Cold email at volume carries legal and deliverability risk you must manage
The Audience
Who Should Use Instantly?
Best for: lead-generation agencies
Agencies running outbound for several clients get unlimited mailboxes, separate workspaces and agency view on Hypergrowth, and pre-warmed mailboxes to launch quickly.
Best for: outbound teams with a deliverability problem
Teams whose emails land in spam from a single domain can spread volume across many warmed mailboxes and monitor placement, which is the job Instantly was built for.
Skip if: you send small volumes or want one all-in-one tool
Founders sending a few hundred personalized emails a month, or teams that want data, sequences and a dialer under one bill, are better served by Apollo.

In The Wild
How People Actually Use Instantly
A lead-gen agency with five clients
Hypergrowth ($77.60 billed annually) adds workspaces, team members and Unibox replies. Buy mailboxes per client, keep each client's sending under Instantly's 30-a-day guidance, and watch bounce rates.
A founder testing outbound
Use the 14-day trial (2 accounts, 250 leads, 1,000 emails), then Growth plus Nano or Growth credits if it works. Note that Growth can't reply from Unibox, so replies go to your own inbox.
An SDR team already on a CRM
Connect HubSpot or Pipedrive natively, or Salesforce through a third-party connector, and use webhooks on Hypergrowth to push interested replies into your pipeline.
The Ecosystem
Instantly Integrations
Instantly connects natively to a few CRMs and to everything else through Zapier, Make, webhooks, its API and MCP.
- →HubSpot (native)
- →Pipedrive (native)
- →Salesforce via OutboundSync (third-party)
- →Zapier (Growth and up) and Make
- →Slack and webhooks (Hypergrowth and up)
- →Clay, Calendly, HighLevel, RB2B
- →API v2, TypeScript SDK, CLI and MCP server
Instantly's CRM page says it connects with major CRMs including Salesforce, but its help center documents Salesforce only through OutboundSync, a third-party connector. Its marketplace lists 50+ sales and outreach integrations.
