CampaignStack vs Linked Helper, compared for agencies

No tool on this list costs less per LinkedIn account. $8.25 a month on an annual Standard plan buys unlimited campaigns, a built-in CRM and a real automation engine, and even Pro at $24.75 undercuts everything comparable. The custody model deserves its own credit: because the app runs on your machine and you sign in inside its own browser, the vendor never touches your password or your session, a cleaner answer than most cloud tools give. And the AI Messages feature ships with the right default, since every generated message lands in a drafts folder and nothing sends until you approve it.

Linked Helper's own help center says it plainly: it is not a cloud solution, and it cannot perform any action while the PC is off or sleeping. For one operator that is a fair trade, since the laptop is open during work hours anyway. For an agency it compounds. Each client account needs a machine that stays on, which in practice means a rented remote server per account, each one an environment you patch, monitor and pay for on top of the license. The vendor's answer to running around the clock is precisely that: install it on a VPS.

CampaignStack runs each account in a persistent, encrypted browser on our infrastructure, included in the $299 workspace price. Onboarding is a session cookie, there is nothing to install, and no client's campaign stops because a machine went to sleep. The safety layer is also enforced rather than recommended: per-action daily budgets with a usage-based warm-up curve, against Linked Helper's configurable caps and a four-week warm-up schedule its blog asks you to follow yourself.

Linked Helper executes the list you feed it, and does so reliably. Who is on that list, whether they still fit after a job change, which ones engaged with a relevant post yesterday, whether the AI draft is actually good: all of that stays your job, per client, per week. AI ICP Detection helps qualify inside a campaign, but there is no standing signal detector, no score that gates campaign membership, and no automated check on a draft beyond your own eyes. There is also no way to script around the gaps, because the integration surface is webhooks and Zapier, not an API.

CampaignStack moves that judgment into the product: signals update lead records as the world changes, ICP scores gate who enters a campaign, a critic reads every draft against its full brief before a human sees it, and the doubtful ones wait in a review queue. All of it is drivable over MCP by the AI tools your team already uses. Clicking send was never where the hours went; they go into everything upstream of it, which is exactly the part Linked Helper leaves to you.
