Four Kinds of LinkedIn Outreach Tools and How to Pick One
Browser senders, cloud sequencers, multichannel platforms and AI SDRs are four different purchases. Choose by asking who answers the replies your invites earn.
Which LinkedIn outreach tools are worth testing at all?
Four categories, and they are four different purchases. Browser-driven senders that click through profiles as you (Dux-Soup, Salesrobot). Cloud sequencers that run with your laptop shut (Expandi). Multichannel platforms where LinkedIn is one channel of five (Apollo.io, HubSpot, ZoomInfo). AI SDRs that write the messages and answer the replies. Three of those sell you sending.
Inside a category the tools are close enough that the choice is mostly price and interface. Across categories they are not comparable. Lists that rank Botdog, HubSpot, Sales Navigator, Apollo.io and ZoomInfo against each other put a LinkedIn sender and a contact database on the same scoreboard, and they are not competing for the same budget line.
Pick the category first by answering one question: who types the reply when a prospect says "what does this cost?"
| Tool | Category | Who writes and answers | Suits |
|---|---|---|---|
| Dux-Soup | Browser extension | You | Solo operators who want a cheap seat today |
| Expandi | Cloud sequencer | You | Agencies running sequences off your machine |
| Salesrobot | Auto-connect + drip | You | Testers comparing cloud vs desktop vs Chrome |
| Apollo.io | Multichannel platform | Your SDRs | Teams where email is the main channel |
| Gelee AI | LinkedIn AI SDR | The AI, in your voice | Founders with no one to answer replies |
Is a LinkedIn-only sender enough on its own?
If you want one clean interface, LinkedIn only, and you are happy writing the copy and answering every reply yourself, a sender like Expandi or Salesrobot is a reasonable pick. It sends, it sequences, it stops when someone replies. What it does not do is talk to anyone.
At 25 invites a day across 20 working days you are sending 500 invites a month. At a 20 to 30% accept rate that is 100 to 150 new connections, and 12 to 18% of those reply to the first message. Somebody answers those 12 to 27 conversations, then the 5 to 8% who only reply after a follow-up.
Those replies do not arrive evenly. A post that lands well puts nine of them in one afternoon, and Thursday's invites go out whether or not Tuesday's nine got answered.
Is a Chrome extension safer than a cloud tool?
Neither is inherently safe. LinkedIn does not publish a daily limit, and what you can get away with moves with account age, how long you have been sending, and whether people accept or ignore you. A brand-new account sending 40 invites a day gets restricted whichever architecture sends them.
Salesrobot tested nine auto-connect tools across cloud, desktop and Chrome and sorts them by safety, which is the right instinct and an unstable ranking. The numbers we run to:
Ramping from 5 a day to 25 takes about two weeks, so a new account sends 150 to 250 invites in month one. Plan the pipeline on that, not on 500.
What results should a tool actually produce?
Across our campaigns: 20 to 30% of connection requests accepted, 12 to 18% reply to the first message, 5 to 8% reply only after a follow-up, and 3 to 5% of total invites turn into a booked meeting. So 500 invites a month is 15 to 25 meetings when the targeting and the offer are right.
That is one meeting per 20 to 33 invites. If you need eight meetings a month, you need 160 to 265 invites and someone to hold roughly 20 conversations.
Accept rates under 10% come from the list or the profile, and the profile is faster to fix. People accept a request, open your profile, and decide from the headline whether to reply. The LinkedIn headline rewriter takes about two minutes and moves accept rates more than any sequence change we have tested.
How much does a cheap seat really cost once you count your hours?
Add the hours before you compare invoices. Running 500 invites a month means list building, writing three or four message variants, and holding 20 to 40 conversations at three to five messages each. That is 20 to 24 hours a month. At $50 an hour it is $1,000 to $1,200 of your own time on top of the seat.
At $100 an hour the same work is $2,000 to $2,400. A $39 seat and a $79 seat are indistinguishable at that point, which is why we wrote up why a $7 seat still costs 24 hours a month.
The flip happens around 20 hours a month, roughly 25 invites a day plus answering the replies. Below that, a seat tool is genuinely the cheapest thing you can buy. The point where a cheap seat stops being cheap is worth working out with your own hourly figure rather than ours.
Why does every "we tested 11 tools" post reach a different answer?
Because most of them are written by a tool vendor. Dux-Soup's own tested list ranks Dux-Soup first. Simular's list names Sai by Simular best for full-stack LinkedIn automation, with Expandi second for cloud-based sequences. Both are useful on the category descriptions and useless on the ranking.
The other pattern is length. Swydo compares 62 tools across four categories and sbl.so lists 40. Nobody tested 40 LinkedIn accounts on 40 tools for a month.
A real test of one sender is three weeks of warm-up at 5 to 10 invites a day, then four weeks at 20 to 25, on an account you are willing to get restricted. You cannot run two senders on one account without doubling the invite count, so a fair head-to-head across three tools needs three accounts and about seven weeks.
Which tool should you buy if you are the only person doing outreach?
If nobody else is going to answer replies, buy the thing that answers them. A founder sending 500 invites a month alone will book meetings for two weeks and then stop, because the 27 open conversations arrive on the days a customer call runs long. The sequence keeps sending either way.
If you have two SDRs who already write good copy, buy them a better sender. Expandi or Salesrobot plus their hours will serve you better than an AI SDR, because you are already paying for the part the AI replaces.
The dividing line is not headcount, it is who has 20 hours a month free. A three-person agency where the founder sells and delivers has nobody with 20 free hours. A ten-person team with one SDR at 60% capacity has them already. We go through that split in why the best tool depends on who answers replies.
What does Gelee do that a sender does not?
It writes the outreach in your voice, answers replies, handles objections from your playbook, and books the meeting on your calendar. Setup takes 15 minutes. There is also a Post Commenters preset that DMs everyone who comments on a post you are watching, then replies to their comment publicly once the DM is confirmed sent.
There is no self-serve signup, so you cannot test it tonight at 11pm the way you can install Dux-Soup and start sending in ten minutes. Pricing is shared on a demo call. If your plan for this week is to trial three tools and cancel two on Friday, a seat tool is the right shape of purchase and we are the wrong one.
Who should not buy any of these?
Three situations. Your buyers are not on LinkedIn, in which case 500 invites a month reaches the wrong people efficiently. Your deal size is under $2,000, so 20 meetings a month does not cover the cost of getting them. Or you have no product-market fit, and more conversations produce more polite no.
One more: if you are sending fewer than 100 invites a month, do it by hand. Five invites a day is 20 minutes, the accept rate runs higher because you actually read the profile, and no tool pays for itself at that volume.
The reason to automate is volume you cannot physically reach. At 500 invites and 27 first-message replies, manual sending costs you a full working week every month. At 100 invites and five replies, it costs you an afternoon.
