In short: for a freelancer, the right LinkedIn prospecting tool is the one whose pace you set, whose messages you approve and whose price you understand. LinkedIn authorizes none of them: its terms forbid robots and extensions that automate activity. Judge on seven criteria and test for 14 days on a small list.
Do you really need a tool to prospect on LinkedIn?
Not always. If you contact a few people a week, LinkedIn search, a spreadsheet and some discipline are enough. A tool helps when volume, follow-ups and tracking go beyond what you can manage by hand.
Time is the main cost: compare the tool's price with your hours, not only with a competitor's price. We detail these budgets in our article on the cost of LinkedIn prospecting for a freelancer.
What does LinkedIn say about prospecting tools?
That none is allowed. LinkedIn's User Agreement, version of 3 November 2025, forbids two things. First, using software, scripts, robots, browser plug-ins or add-ons to scrape or copy the service. Second, using bots or other unauthorized automated methods to send messages or add contacts (LinkedIn, section 8.2, consulted on 7 October 2026).
The possible sanction is a restricted or closed account, and the tool may stop working without notice (LinkedIn Help, consulted on 7 October 2026). Be wary of any ad that promises zero risk. The criteria below reduce exposure, they do not remove it.
Where does the tool run, and can you set its pace?
Criterion 1: where it runs. In your browser or on the vendor's servers. A Chrome extension works from your computer and your usual connection, but LinkedIn does look for extensions. BleepingComputer reported on 3 April 2026 that a script on the site detects 6,236 of them (BleepingComputer, consulted on 7 October 2026). A cloud tool uses your session from another location.
Neither model is safe by nature. Our article on LinkedIn automation limits compares the two in detail. Keep the practical constraint in mind: an extension needs your computer to stay on while it sends.
Criterion 2: pacing. Require a daily cap, sending hours and a delay between actions, all adjustable. LinkedIn lists as reasons for restriction many invitations sent in a short time, and many invitations ignored or marked as spam (LinkedIn Help, consulted on 7 October 2026).
A tool that imposes its own pace, or hides its caps, takes away the only lever you have. Also check whether it lets you start low and ramp up. Sales Farmer's settings are described on the limits and safety page.
Who writes the messages, and does the sequence stop at a reply?
Criterion 3: approval. AI can help write, but should not decide alone. Expandi compared, within the same accounts, AI-written campaigns with hand-written templates. AI gets 12% less acceptance, with an equal reply rate (Expandi, State of LinkedIn Outreach H2 2026, consulted on 7 October 2026). A tool vendor publishes this, not an opponent of AI.
Look for a tool that proposes an editable draft, shows why it suggests this person, and contacts nobody without your approval. In Automatic mode, Sales Farmer shows the reason for each contact and a first message to edit; you approve before sending.
Criterion 4: stopping at a reply. It avoids the most awkward mistake: following up with someone who just answered. Check that the stop is automatic, and that follow-ups change angle instead of repeating the first message.
On length, the same Expandi data shows three messages give 9.8% replies, against 5.0% from five onwards. A tool that encourages endless sequences works against you. See the LinkedIn sequences page.
Do you need to pay for Sales Navigator on top?
Criterion 5: source of the list. Not necessarily. Expandi compared nearly 11,000 campaigns fed by an imported file or by a Sales Navigator search, covering 2.2 million people. Acceptance is 18.5% for the file and 19.8% for Sales Navigator, with identical replies (Expandi, consulted on 7 October 2026).
Check that the tool can take a list from a standard LinkedIn search or a file. Sales Farmer does not make Sales Navigator mandatory, as the extraction page shows. Our article on Sales Navigator pricing helps you decide whether the subscription brings you anything else.
What happens to personal data?
Criterion 6: data. You remain responsible for what you collect. The CNIL, the French data protection authority, accepts that prospecting professionals rests on legitimate interest. The subject must relate to their profession, and the person must be informed and able to object (CNIL, updated 10 June 2026, consulted on 7 October 2026, in French).
Ask where the tool hosts data and how you delete a person. Sales Farmer hosts its data in the European Union, in Frankfurt, which avoids a transfer outside the Union without settling the other questions. Our GDPR article details the checklist.
Is the price readable, and can you try before paying?
Criterion 7: price. Count the total, not the headline. Look at the commitment period, the gap between monthly and annual prices, and what is capped (invitations, campaigns, accounts). Ask for a trial with no credit card so you can test on a small list.
At Sales Farmer, the Starter plan costs $15 a month and the Growth plan $39, with a 14-day trial and no card (pricing). These figures are ours: compare them with the official pricing pages of other vendors before deciding, since prices change.
FAQ
Is there a LinkedIn prospecting tool that LinkedIn allows?
Not to our knowledge. LinkedIn's User Agreement forbids robots and extensions that automate activity. Tools differ in pacing and control, not in authorization.
Chrome extension or cloud tool for a freelancer?
The same rules apply to both. The extension stays in your browser and needs a computer that is on; the cloud runs without you. The choice depends on your working rhythm and your tolerance for risk.
Is it better to start by hand?
For a few people a week, yes. Move to a tool when follow-ups and tracking take more time than writing.
How long does it take to judge a tool?
Two weeks on a list of a few dozen people gives a first picture of acceptances and replies. It does not replace a longer test on your market.
Try before you pay
Sales Farmer's 14-day trial needs no credit card: launch a small campaign, look at the results by step and decide afterwards. Plans start at $15 a month.
