Instantly.ai vs Amplemarket: Which Cold Outreach Tool Is Superior?

If you're comparing Instantly vs Amplemarket, you're choosing between two very different kinds of outbound tool. Instantly is a cold email sender with add-ons for leads, CRM, and deliverability tests. Amplemarket is an all-in-one sales platform sold on annual plans with set user counts.

On October 15, 2026, I went through both live pricing pages, read every feature grid, and flipped Instantly's toggle between monthly and yearly billing. Some of the most useful details only show up there, like which Instantly plan includes a reply inbox.

Salesforge is the third option: email and LinkedIn in one sequence, no per-seat pricing, and the rest of the Forge Stack behind it. Here is how all three compare.

Cold Outreach Platform Comparison at a Glance: Instantly vs Amplemarket

Instantly.ai Overview: Features, Pricing, and Limits

Instantly is a cold email platform built around unlimited email accounts and unlimited warm-up on every plan. It also sells a lead database, a CRM, AI agents, and its own sending accounts, each billed separately from the core Outreach plan.

Instantly core features

• Unlimited accounts and warm-up: connect any number of mailboxes on every Outreach plan, with advanced warm-up from Hypergrowth.
• Campaigns: sequences, scheduling, and email analytics on every plan, with A/Z testing from Hypergrowth.
• Unibox: a reply inbox for campaign responses, included from Hypergrowth at $97/mo.
• Lead database: 450M+ B2B leads with waterfall enrichment across 5+ providers, sold as Data Credits from $9/mo.
• AI agents: AI reply, sales, and voice agents, with the reply and sales agents running on Data Credits.
• Sending accounts: domains at $15/yr, AirMail accounts at $4/mo, done-for-you Google accounts at $5/mo, and pre-warmed Google accounts at $10/mo.
• CRM and Inbox Placement: separate add-ons at $47 or $97/mo each, and Inbox Placement checks 94 blacklists.

Unibox is where campaign replies land, sorted by lead status such as Interested and Meeting booked.

Instantly pricing

Instantly Growth costs $47/mo monthly or $37.60/mo yearly for 1,000 uploaded contacts and 5,000 emails a month. Hypergrowth is $97/mo or $77.60/mo yearly for 25,000 contacts and 125,000 emails. Light Speed is $358/mo or $286.30/mo yearly for 100,000 contacts and 500,000 emails.

When I checked on October 15, 2026, the Hypergrowth card said 125,000 emails while the feature grid on the same page said 100,000. Instantly's help center also states that each workspace requires its own subscription.

Who Instantly fits and where it falls short

Instantly fits founders and small teams that only send cold email and want high volume for a low monthly fee. On email volume per dollar, Hypergrowth beats Salesforge Growth: 125,000 emails for $97/mo versus 50,000 for $96/mo.

• There is no native LinkedIn sending. Automations hand leads to separate LinkedIn tools, as this Instantly and HeyReach breakdown shows.
• The $47 Instantly Growth plan has no Unibox, team invites, A/Z testing, or API access.
• Outbound, Data Credits, CRM, and Inbox Placement are four separate subscriptions, and each workspace needs its own Outbound plan.

What Instantly reviewers say

Instantly has 1,174 reviews on Trustpilot. A 1-star review from October 12, 2026 describes the plan gate above. After downgrading from $97 to $47 a month, the reviewer lost Unibox and could no longer reply to leads inside Instantly.

Amplemarket Overview: Features, Pricing, and Limits

Amplemarket is an AI sales platform that bundles a B2B database, intent signals, multichannel sequences, a dialer, and deliverability tools. Its plans include a set number of users, and the Startup plan runs on an annual term.

Amplemarket core features

• Data and signals: contact and company search, AI intent signals, job change alerts, and 200M verified mobile numbers.
• Duo AI: Duo Copilot and Duo Copywriter on every plan, plus Duo Voice for AI voice messages from Amplemarket Growth.
• Multichannel sequences: email, LinkedIn connection requests and DMs (including voice and video DMs), and calls through a built-in dialer.
• Quick follow-ups: one-click WhatsApp and iMessage messages for warm prospects.
• Unibox: one inbox for email and social messages with AI labels, with Duo Inbox AI reply drafts included on Elite.
• Deliverability: Deliverability Booster warm-up and a Domain Health Center on all plans, plus a spam checker from Amplemarket Growth.
• MCP and AI agents: prospect and research from Claude or ChatGPT on every plan.

Duo Copilot pairs each lead's signals with a recommended sequence, like the email, social, and voice steps below.

Amplemarket pricing

Amplemarket Startup costs $600/mo on an annual term, so the minimum is $7,200 a year. It includes 2 users, 13,500 email credits and 600 phone credits per user each year, and 2 mailboxes per user to start.

Amplemarket Growth (4 users, 4 mailboxes per user) and Elite (10 users, 8 mailboxes per user, SSO) are custom-priced. I found no monthly billing option on its pricing page.

Who Amplemarket fits and where it falls short

Amplemarket fits sales teams that want data, signals, LinkedIn, and phone from one vendor on one annual contract. Its own pricing page pitches Startup at small businesses, startups, and founder-led teams. If cold calling is a core channel, its dialer and mobile data cover phone outreach, which Salesforge does not offer yet.

• The entry price is $7,200 a year for 2 users, and each extra user is bought on top.
• Mailboxes scale with seats: 2 per user on Startup, 4 on Amplemarket Growth, and 8 on Elite to start.
• Automatic reply drafts cost extra: Duo Inbox is missing from Startup and is a paid add-on on Amplemarket Growth.
• The Get free trial button opens a Book a demo page, so the trial starts with a sales call.

What Amplemarket reviewers say

Amplemarket has no reviews on Trustpilot. This 2-star G2 review from 2024 says it started charging extra for an event research feature that was sold as part of the reviewer's package.

Most of its reviews sit on G2, where it held a 4.6 rating from 687 reviews in early October 2026. Repeat complaints cover missing features, a learning curve, AI targeting that sometimes picks the wrong companies, stale phone numbers, and annual-only billing.

Salesforge Overview: Email and LinkedIn Outreach on the Forge Stack

Salesforge is a multichannel outreach platform that runs cold email and LinkedIn inside one sequence and one inbox. More than 10,000 businesses use it, and it is the outreach layer of the Forge Stack.

Salesforge core features

• Unlimited mailboxes, users, and workspaces: no mailbox or workspace limits on any plan, and Growth adds unlimited users and LinkedIn senders.
• Multichannel with conditional sequences: if a connection request is accepted, a LinkedIn message goes out; if not, the sequence falls back to email.
• Six native LinkedIn actions: connection requests, messages, InMails, post likes, follows, and withdraw requests, each capped at 30 per day per profile.
• Account safety as standard: session-token login, so your LinkedIn password is never stored, plus shared proxies and no Chrome extension injection.
• AI personalization across 21+ languages: AI variables can pull company news, LinkedIn activity, and industry context into any message.
• Unlimited warm-up via Warmforge: every connected mailbox warms for free in a premium pool, with a Heat Score™ for each one.
• Deliverability guards: Bounce Shield, built-in email validation, sender rotation, text-only emails, and ESP matching on Growth.
• Primebox™ with Autopilot and Co-pilot modes: one inbox for email and LinkedIn replies on every plan, with the AI reply modes on Growth.
• LinkedIn email & phone finder Chrome Extension: powered by Leadsforge's 500M+ contacts, with 100 free credits on signup.
• Testing and analytics: open, reply, positive reply, connection acceptance, and meeting rates, with A/B testing on Growth.
• API, MCP, and CLI: the open API, MCP server, and CLI come with Growth, so Claude, Cursor, or your own agents can run campaigns.

The Forge Stack behind Salesforge

Salesforge is one layer of the Forge Stack. Mailforge, Infraforge, and Primeforge supply mailboxes, Warmforge handles deliverability, Leadsforge finds leads, and Agent Frank runs outbound end to end. Neither competitor covers every layer: Instantly has no native LinkedIn sending, and I found no mailbox product in the Amplemarket menu.

Each product is a separate subscription, but they share one login and sync natively, with no Zapier or Make in between. You can run the stack three ways: with your own team, with Agent Frank, or through a vetted Forge Expert agency.

Salesforge pricing

Salesforge Pro costs $48/mo monthly or $40/mo annual for 1 user, 1 LinkedIn sender, 1,000 active contacts, and 5,000 emails a month. Salesforge Growth costs $96/mo monthly or $80/mo annual for unlimited users and LinkedIn senders, 10,000 active contacts, and 50,000 emails a month.

Growth also adds the API, A/B testing, ESP matching, multi-language sequences, and Primebox™ AI. Agent Frank is a separate subscription at $499/mo billed quarterly ($416/mo billed annually). You can verify credit limits on the live pricing page.

Who Salesforge fits

Salesforge says it fits B2B teams selling at $5K-$100K ACV to startups, SMBs, and mid-market companies, with 3,000 or more target businesses. It also says it is a poor fit if you mainly target Fortune 500 companies or depend on long RFP cycles.

ChannelCrawler reached an 85.71% positive reply rate running Salesforge with Infraforge and Warmforge.

Salesforge limitations

• Mailboxes are not included, so you bring your own or buy them from Mailforge, Infraforge, or Primeforge.
• LinkedIn actions use social action credits: 300 a month on Pro and 1,000 on Growth. One active profile uses about 400-500, so busy teams buy more in-app.
• The API, MCP server, CLI, and full integrations library need Growth. Agent Frank needs a sales-led demo and a 2-week warm-up, and phone outreach is still on the roadmap.

Head-to-Head Feature Comparison: Instantly vs Amplemarket

Multichannel outreach: email, LinkedIn, and phone

• Instantly: email campaigns only. Automations can pass leads to separate LinkedIn tools, and an AI voice agent can place calls inside workflows.
• Amplemarket: email, LinkedIn connection requests and DMs, and calls through a built-in dialer, all in one sequence.
• Salesforge: email plus six native LinkedIn actions in one conditional sequence, with phone on the roadmap.

If cold calling drives your pipeline, Amplemarket covers a channel Salesforge does not offer yet. For email plus LinkedIn, Salesforge Growth is the only plan of the three with unlimited LinkedIn senders and no per-seat fees.

Pairing Instantly with a separate LinkedIn tool means paying for at least two subscriptions to work prospects on both channels.

Email deliverability, warm-up, and infrastructure

• Instantly: unlimited warm-up on every plan, with advanced warm-up from Hypergrowth. Placement tests and checks against 94 blacklists cost $47-$97/mo extra.
• Amplemarket: Deliverability Booster warm-up and a Domain Health Center on all plans, plus a spam checker from Amplemarket Growth.
• Salesforge: free, unlimited Warmforge warm-up in a premium pool of aged IMAP/SMTP, Google Workspace, and Microsoft 365 mailboxes, with multilingual traffic.

Salesforge's Instantly vs Salesforge comparison flags questionable domains, such as lust.com, in Instantly's warm-up pool. More detail is in this Instantly warm-up review.

Warmforge also tracks a Heat Score™ per mailbox (97+ is healthy) and runs DNS, MX, and blacklist checks. Standalone, it costs $9 per mailbox slot a month on annual billing, and Salesforge includes it free. You can also run free deliverability tools without signing up.

For mailboxes, Mailforge (shared), Infraforge (dedicated IPs), and Primeforge (Google Workspace and Microsoft 365) run under one login, so you can switch as you scale. They cost $2 to $4.50 per mailbox a month on annual billing, and this cold email infrastructure guide covers setup.

AI personalization and AI SDRs

• Instantly: AI email writer and web researcher agents, plus AI reply and sales agents, all running on Data Credits.
• Amplemarket: Duo Copilot, Duo Copywriter, and intent signals on every plan, with Duo Voice from Amplemarket Growth.
• Salesforge: AI personalization across 21+ languages, where Overdrive Mode pulls from every source for 2 credits per preview and regeneration is free.

Agent Frank is the Salesforge AI SDR. He prospects from the Leadsforge 500M+ database, enriches each contact, and writes email and LinkedIn messages. He follows up, handles replies in Primebox™, and books meetings on your calendar 24/7, in Auto-Pilot or Co-Pilot mode.

VAI Consulting booked 3 calls with him in the first week after tightening its ICP. He is a separate subscription from $499/mo billed quarterly for 1,000 active contacts, and he needs a demo and a 2-week warm-up first.

Inbox management and reply handling

• Instantly: Unibox comes with Hypergrowth at $97/mo. On Instantly Growth, replies stay in each mailbox's own inbox.
• Amplemarket: Unibox covers email and social messages with AI labels. Duo Inbox automatic reply drafts come with Elite, or as an add-on on Amplemarket Growth.
• Salesforge: Primebox™ is on every plan. It combines email and LinkedIn replies, catches replies sent from a different address, and tags sentiment.

Here is the Primebox™ view, with email and LinkedIn replies in one list.

Salesforge Growth adds Autopilot and Co-pilot AI reply modes at 3 credits per draft. Primebox™ also has a mobile app, follow-up reminders, and saved reply templates. This video shows how it pulls every conversation into one view.

Pricing scalability: seats, workspaces, and mailboxes

• Instantly: no per-seat price, but each workspace needs its own subscription, and team invites start on Hypergrowth.
• Amplemarket: plans include 2, 4, or 10 users, extra users cost more, and mailboxes are allotted per user.
• Salesforge: unlimited workspaces on every plan, and Salesforge Growth adds unlimited users and LinkedIn senders.

Take an agency with 5 clients sending about 8,000 emails each per month. Each workspace passes the 5,000-email cap on Instantly Growth, so 5 Hypergrowth plans cost $485/mo. One Salesforge Growth plan covers all 5 workspaces and 40,000 emails for $96/mo, before mailboxes.

On Amplemarket, the same agency would start at $7,200 a year for 2 users before adding seats or mailboxes.

Integrations, lead data, and API

• Instantly: API, webhooks, and integrations start on Hypergrowth, and Automations connect tools like HubSpot, Pipedrive, and Slack. Its 450M+ lead database runs on Data Credits from $9/mo.
• Amplemarket: integrations, MCP access, and AI agents on every plan, with SSO only on Elite. Data is bundled at 13,500 to 40,000 email credits per user a year.
• Salesforge: native sync with HubSpot, Salesforce, Pipedrive, HighLevel, Attio, Folk, and Breakcold, plus Slack, Zapier, Make, and webhooks. Data tools include Clay, Bitscale, RB2B, Databar AI, Persana AI, Sendspark, and Weezly, with the full library on Salesforge Growth.

Leadsforge searches 500M+ contacts by chat, adds waterfall enrichment and intent signals, and sends lists straight into Salesforge sequences with no CSV export.

On Salesforge Growth, the MCP server and CLI let Claude, Cursor, or your own agents create contacts and launch sequences across the Forge Stack. Salesforge is also SOC 2 compliant.

Instantly vs Amplemarket vs Salesforge Pricing in 2026

All three sell a plan called Growth, so each carries its vendor's name.

Instantly's listed price is the lowest, but its $47 plan leaves out Unibox, team invites, and the API, which start on Hypergrowth. Leads, CRM, and placement tests then cost extra. On raw email volume, Hypergrowth gives more: 125,000 emails for $97/mo versus 50,000 on Salesforge Growth at $96/mo.

Amplemarket bundles data into the price, but the minimum is $7,200 a year and every new rep adds a seat. Salesforge Growth covers both channels for any number of users at one plan price, with no separate LinkedIn license.

Cost scenario: 3 reps, 20,000 emails a month

Say 3 reps send 20,000 emails a month to 5,000 prospects from 30 Google mailboxes, with LinkedIn touches and lead data. Prices use annual billing; domains are extra.

Salesforge costs $1 to $31 less than Instantly and includes LinkedIn senders for all three reps. Heavy LinkedIn use needs extra action credits. Amplemarket costs more than double before the third seat.

Who Should Use Instantly, Amplemarket, or Salesforge

You might consider Instantly if:

• You only send cold email and want high volume per dollar, such as 125,000 emails for $97/mo on Hypergrowth.
• You want to buy Google or AirMail sending accounts from the same vendor that runs your campaigns.

You might consider Amplemarket if:

• Cold calling is a core channel. Its built-in dialer and 200M verified mobile numbers cover phone, which Salesforge does not offer yet.
• You can commit at least $7,200 a year and want data, signals, and sequences on one contract with a CSM.

Choose Salesforge if:

• You sell B2B at $5K-$100K ACV to startups, SMBs, or mid-market companies and target 3,000+ businesses.
• You want email and LinkedIn in one conditional sequence, with every reply in Primebox™.
• Your team is growing: Salesforge Growth covers unlimited users, LinkedIn senders, mailboxes, and workspaces for $80/mo annual.
• You run a lead-gen agency and want one plan for every client workspace, with three infrastructure options under one login.
• You want an AI SDR: Agent Frank runs the workflow 24/7 as a separate subscription from $499/mo billed quarterly.

Final Verdict: Which Cold Outreach Platform to Choose in 2026

Instantly and Amplemarket solve different problems. Instantly is a high-volume email sender whose cheapest plan leaves out its own reply inbox, with leads, CRM, and inbox tests billed separately. Amplemarket is a full sales platform with phone and data built in, but it starts at $7,200 a year for two users.

For B2B teams running email and LinkedIn outbound, Salesforge is the stronger choice. At $80/mo billed annually ($96/mo monthly), Salesforge Growth is the only plan of the three with unlimited users and LinkedIn senders and no per-seat fees. Unlimited mailboxes, free Warmforge warm-up, and Primebox™ come included.

One falsifiable benchmark: UniteSync ran Salesforge with Mailforge and Warmforge to an 85.26% positive reply rate and a $2.86 CAC. The case study is public.

If you sell mainly to Fortune 500 accounts through long RFP cycles, Salesforge itself says it is not the right fit. Salesforge says it fits SMB and mid-market deals between $5K and $100K ACV.
