Linked Helper vs Zopto: Which Cold Outreach Tool Is Superior?

I have spent the last few years running outbound across both email and LinkedIn, and the same three names kept coming up: Linked Helper, Zopto, and Salesforge. So I set all three up and put them through real campaigns.

One surprise up front. Zopto no longer exists as a product you can buy. It shut down in February 2026, and its domain now points to a done-for-you agency called Zeekeo. Linked Helper is still here, a cheap desktop app built purely for LinkedIn. Salesforge runs email and LinkedIn together in a single sequence, with warm-up and a unified inbox included.

This comparison covers what each tool is, what it costs today, and which one fits the way modern B2B teams actually prospect.

LinkedIn Automation Tools Compared at a Glance: Linked Helper vs Zopto

Here is the short version before the detail. One tool is a live desktop app, one is gone, and one runs both channels at once.

Linked Helper Overview: Features, Pricing, and Limitations

Linked Helper is one of the longest-running LinkedIn automation tools on the market. It runs as a desktop application on Windows, Mac, or Linux, driving a built-in browser session connected to your LinkedIn account. In 2026 it added a cloud-storage option that syncs your data, but the automation itself still runs from the app.

Core features I tested:

• Connection and message campaigns: automated invites, follow-up sequences, and reply detection across LinkedIn.
• Campaign chaining: prospects who accept an invite move into a messaging campaign automatically, which builds multi-step LinkedIn flows.
• InMail, events, and group messaging: most native LinkedIn action types are covered.
• Built-in CRM: tagging, notes, and full-profile data scraping inside the app.
• Data enrichment: email and phone lookups via monthly data credits (620/mo on Standard, 3,100/mo on Pro).
• AI credits: AI Messages, AI Comments, and AI ICP detection, metered by an AI credit balance.
• Platform support: works with free LinkedIn, Premium, Sales Navigator, and Recruiter.

Pricing is per LinkedIn account, and one license equals one account. On the local-storage tiers, Linked Helper Standard is $15/mo monthly, dropping to roughly $8.25/mo on the 12-month term. Linked Helper Pro is $45/mo monthly, dropping to about $24.75/mo annually. The cloud-storage versions cost more: Standard is $29.90/mo and Pro is $59.90/mo on monthly billing. There is a 14-day free trial with no card required.

It is best for solo operators, recruiters, and small teams who want granular control of LinkedIn outreach on a tight budget and do not mind managing the machine themselves.

What reviewers say about Linked Helper

The desktop model is the source of most complaints. Because actions come from a single home or office IP, LinkedIn's detection systems can flag the pattern, and reviewers report restrictions even inside the recommended daily limits.

Other documented limitations: the local app needs your computer on to run, and it has a steep learning curve. There is also no unified inbox that merges LinkedIn replies with email, since email is not a sending channel here.

Zopto Overview: What Happened and Where It Went

Here is the part almost no other comparison page will tell you plainly. As a self-serve product, Zopto no longer exists. It permanently shut down in February 2026 with no advance warning, and the Zopto shutdown left thousands of users looking for a replacement.

Zopto was founded in 2018 in London and ran for years as a cloud-based LinkedIn automation platform. It sold in three self-serve tiers: Personal at $215/mo, Grow at $395/mo, and Agency at $895/mo. That is the Zopto most G2 and Capterra reviews still describe. The UK company behind it, Zopto Limited, was formally dissolved on 19 May 2026.

What it used to do, for context:

• Cloud LinkedIn automation: connection requests, messages, InMails, profile views, and post engagement, run from dedicated cloud servers.
• Targeting: filtering built on LinkedIn Sales Navigator, which it required to work fully.
• AI assistant: a GPT-based helper for templates and posts on higher tiers.
• Email steps: available on its higher tiers for basic multichannel touches.
• Agency features: a multi-account dashboard and client reporting.

If you type the domain today, it redirects to Zeekeo, positioned as a B2B lead generation agency. The offering is now Zeekeo Launchpad, a DIY tool at $120/seat/mo billed quarterly, or Zeekeo Elite, a managed service from $649/mo. The only call to action is "Book a Call," with no self-serve signup or free trial. If you were a Zopto customer, this is effectively a different company and a different model. Anyone still searching for Zopto alternatives is really shopping for a new tool.

Salesforge Overview: Multichannel Outreach and the Forge Stack

Salesforge is a multichannel outbound platform that runs cold email and LinkedIn as coordinated channels inside one sequence and one inbox. It is the outreach layer of the full Forge Stack, which also includes Mailforge, Infraforge, Primeforge, Warmforge, and Leadsforge.

Core features:

• Conditional multichannel sequences: email and LinkedIn steps branch on prospect behavior. If a connection request is accepted, send a LinkedIn message; if not, fall back to email.
• Six native LinkedIn actions: connection requests, messages, InMails, post likes, follows, and withdraw requests, each capped at 30/day per profile for safety.
• Unlimited LinkedIn senders and mailboxes: on the Growth plan, connect your whole team without per-seat fees.
• Account safety: actions route through quality proxies with session-token auth, so your LinkedIn password is never stored, and there is no browser-extension injection.
• Free Warmforge warm-up: every mailbox is warmed continuously through a free Warmforge warm-up pool of aged Google Workspace and Microsoft 365 mailboxes, with Heat Score™ monitoring.
• Primebox™ unified inbox: all email and LinkedIn replies land in one place, free on every plan; AI reply modes (Autopilot and Co-pilot) are on Growth.
• AI personalization in 21+ languages: Overdrive Mode pulls from multiple sources per prospect.
• Three infrastructure options: Mailforge, Infraforge, and Primeforge under one login.
• Leadsforge: a Leadsforge lead database of 500M+ contacts that feeds sequences with no CSV export.
• Integrations: HubSpot, Salesforce, Pipedrive, Clay, Zapier, Make, webhooks, an API on Growth, and an MCP CLI.

Pricing is not seat based. Salesforge Pro is $48/mo monthly or $40/mo annual, with 1,000 contacts, 5,000 emails a month, one user, one LinkedIn sender, and unlimited mailboxes. Salesforge Growth is $96/mo monthly or $80/mo annual, adding unlimited users, unlimited LinkedIn senders, A/B testing, ESP matching, API access, and the full integrations library. An optional AI SDR, Agent Frank, is a separate subscription from $499/mo billed quarterly ($416/mo annual); he requires a demo and a two-week warm-up, so there is no self-serve trial for him. Every paid plan includes a 14-day free trial with no card.

Salesforge is built for B2B teams selling at ACVs of $5K to $100K, targeting 3,000 or more businesses. It is honest about fit: Salesforge itself says it is a poor match for Fortune 500 procurement and long RFP cycles. Named outcomes make the case concrete. UniteSync hit an 85.26% positive reply rate and a $2.86 CAC on Salesforge, Mailforge, and Warmforge, and ChannelCrawler reached 85.71% on Salesforge, Infraforge, and Warmforge.

Two honest limitations: email infrastructure is not bundled into the base price, and several features (API, A/B testing, Primebox AI, unlimited LinkedIn senders) sit on the Growth plan.

Head-to-Head Feature Comparison: Linked Helper vs Zopto

Since Zopto is discontinued, this section weighs Linked Helper as the live competitor and treats Zopto as the cautionary case, with Salesforge as the reference point.

Multichannel outreach

This is the widest gap. Cold outreach in 2026 works best when LinkedIn and email reinforce each other in one flow.

• Salesforge: email and LinkedIn run in a single conditional sequence, so a missed email can trigger a LinkedIn touch automatically.
• Linked Helper: LinkedIn only. You can chain LinkedIn campaigns, but email lives in a separate tool entirely.
• Zopto: offered email steps on its higher tiers, but the product is no longer available.

Email deliverability and warm-up

Deliverability is what kills most cold campaigns, and it only matters once email is in the picture.

• Salesforge: free, unlimited Warmforge warm-up on every mailbox, with a premium pool and Heat Score™ tracking, plus ESP matching and mailbox rotation.
• Linked Helper: no warm-up, because it does not send email.
• Zopto: no first-party warm-up product; deliverability was never its focus.

LinkedIn safety and deployment

How the tool executes LinkedIn actions changes your account risk.

• Salesforge: cloud execution, quality proxies, session-token auth, conservative per-action caps, and no extension injection.
• Linked Helper: desktop execution from your own IP. Reviewers report restrictions, and the app has to stay running on the local tier.
• Zopto: ran in the cloud with dedicated IPs, which was a genuine strength before it closed.

AI and personalization

• Salesforge: Overdrive Mode personalizes from multiple sources in 21+ languages, and Agent Frank can run the whole workflow as an AI SDR.
• Linked Helper: AI Messages and AI ICP detection exist, metered by AI credits, but there is no autonomous SDR.
• Zopto: had a GPT-based template helper on higher tiers.

Inbox and reply management

• Salesforge: Primebox™ merges email and LinkedIn replies in one inbox with sentiment analysis, free on every plan.
• Linked Helper: a built-in CRM handles LinkedIn conversations, but email replies are not part of it.
• Zopto: had a team inbox for managing replies, now retired.

Infrastructure and integrations

• Salesforge: three infrastructure options (Mailforge, Infraforge, Primeforge), native CRM integrations, an API on Growth, and an MCP CLI for agent workflows.
• Linked Helper: no email infrastructure; integrations run through webhooks and Zapier (capped at 20 profiles/day on Standard).
• Zopto: integrated with HubSpot, Salesforce, and Zapier during its run.

Pricing Comparison: Linked Helper, Zopto, and Salesforge

Sticker prices sit far apart, but the real cost depends on channels and scale. Note that both Linked Helper and Salesforge have a "Pro" tier, so I name the vendor each time.

Linked Helper is genuinely the cheapest way to automate LinkedIn if you run a single account and stay LinkedIn-only. For that narrow, budget-first case it is the simpler pick, because it skips the email setup you would not use.

The math shifts the moment you add email or a second seat. Say you run a five-person team doing email and LinkedIn. On Linked Helper you would pay per LinkedIn account and still buy a separate email tool, a warm-up tool, and a data tool on top. On Salesforge Growth at $80/mo annual, five users, all their LinkedIn senders, unlimited mailboxes, free warm-up, and Primebox™ are covered by one flat fee. Zopto, by contrast, started at $215/mo for one account and required Sales Navigator on top, which is part of why so many teams moved on even before it closed.

Who Should Use Which Tool

A quick decision guide based on how you actually work.

You might consider Linked Helper if:

• You run one LinkedIn account, want maximum manual control, and are on a strict budget.
• Your outbound is LinkedIn-only and you are comfortable keeping a desktop app running.
• You accept a higher detection risk in exchange for the lowest sticker price.

You might have considered Zopto if:

• You wanted cloud-based LinkedIn automation with agency dashboards, before it shut down.
• Today, the equivalent is a managed Zeekeo engagement, not a self-serve tool you operate.

Choose Salesforge if:

• You sell B2B at ACVs of $5K to $100K and target 3,000+ businesses.
• You want email and LinkedIn in one conditional sequence, not two disconnected tools.
• You are scaling a team or agency and refuse to pay per seat as you grow.
• You want deliverability handled for free, with warm-up, ESP matching, and a unified inbox built in.
• You want the option to hand the whole workflow to Agent Frank, the AI SDR.

Final Verdict: The Best LinkedIn Outreach Tool for 2026

Linked Helper and Zopto are both single-channel tools at heart. Linked Helper is a low-cost desktop app that automates LinkedIn well but leaves email, warm-up, and a shared inbox out of the picture. Zopto was a capable cloud tool, but it shut down in February 2026 and now redirects to a done-for-you agency, so it is not something you can buy and run yourself.

For real multichannel B2B outbound, Salesforge is the stronger choice. At $80/mo for the Growth plan billed annually ($96/mo monthly), you get unlimited users, unlimited LinkedIn senders, unlimited mailboxes, free Warmforge warm-up, and Primebox™, a combination neither alternative offers at any price.

One falsifiable benchmark: UniteSync ran on Salesforge, Mailforge, and Warmforge to an 85.26% positive reply rate and a $2.86 CAC. The case study is public. If you primarily sell to Fortune 500 accounts through long RFP cycles, Salesforge says plainly that it is not your tool. For SMB and mid-market outbound, it is purpose-built.
