Among LinkedIn and email outreach tools, La Growth Machine ranks first for an agency running outreach on client LinkedIn accounts. It runs in the cloud, gives each identity a dedicated mobile proxy and puts LinkedIn and email on its cheapest plan. Reply.io is second for one of the widest channel sets and an agency plan. Skylead is third for agency bundles. CampaignStack, which we make, is fourth.
We checked prices and features on each vendor's own site in October 2026.
We make one of these tools. It's on the list and it isn't first. We wrote the criteria before we ranked anything. Every other "best multichannel outreach tools" page we found was written by a vendor for an in-house SDR team, and most put their own tool first. This one is for you if you run outbound for 5 to 20 clients on LinkedIn accounts that belong to them. One restricted account can cost you the client.
How we ranked them
We asked five questions of every tool, in this order.
- LinkedIn and email in one sequence, running without your laptop. Does the tool run in the cloud, with LinkedIn steps that send on their own instead of waiting as tasks for you to click?
- Account safety on client accounts. Does it enforce limits and warm up new accounts? Will it give a straight answer to "what IP does the session leave from?"
- Running many client accounts. Does it have client workspaces, an agency dashboard or white-label?
- Human review before send, inside the product. Can someone approve a message before it reaches a client's prospect, without going through an AI chat app?
- Pricing unit fit. Is the price per user, per seat, per LinkedIn account, per identity or per workspace? That decides what adding a client costs you.

CampaignStack is our product. "Starts at" is each vendor's cheapest plan that has both LinkedIn and email steps, with its own unit and billing basis.
1. La Growth Machine
What it does well. LinkedIn and email share one sequence, and a reply on either channel stops it. It runs in the cloud, and each user gets a dedicated 5G mobile IP ("you're the only one using it"), with daily limits and working hours per identity.
You can add a manual check to any LinkedIn message or email step, so each lead gets a review task before it sends. There's an Agency plan for lead-gen agencies (6 identities minimum) and a 14-day free trial with no card.
The catch. Basic covers up to 3 identities, 1 sending email per identity and 3 running campaigns. AI Messages starts on Pro, and it writes one message per step, the same for every lead in that step. We found no mention of white-label on the pages we read.
Pick it if you want a mobile IP per identity and LinkedIn plus email from the first plan, and you can live without branded client access.
2. Reply.io
What it does well. Reply.io has one of the widest channel sets here: email, LinkedIn, SMS, phone and semi-automated WhatsApp, all in one flow. LinkedIn steps cover connection requests, messages, profile views, InMails and post likes, and you can keep chosen steps semi-automated.
It recommends daily limits per LinkedIn action, pauses at the limit and cleans up pending requests. You can preview and adjust LinkedIn messages before they go out. Agency Core adds an agency dashboard, role-based access, no cap on clients or users, and optional white-label.
The catch. The pages we read don't say where the LinkedIn session runs or what kind of IP it uses. Each Multichannel user includes 1 LinkedIn account, and extra LinkedIn accounts cost extra. Mailboxes per user differ between the monthly card (5) and the annual card (10).
Pick it if your clients want calls or SMS in the same flow, or you need white-label and an agency dashboard on one plan.
3. Skylead
What it does well. One Skylead seat covers cloud LinkedIn automation and email. You can connect as many email accounts as you like at no extra cost, and All-in-one includes 100,000 emails a month. Agencies get one dashboard for all clients and seats, one inbox for every client conversation, client roles and a white-label option, sold as flat agency bundles. There's a 7-day free trial.
The catch. Skylead documents review before send for AI SDR replies (a semi-automatic mode), and we found nothing like it for regular sequence steps. The pages we read don't name the IP type. The agency bundle is a "first-year promotion", and two of Skylead's own pages give it different seat counts, so ask before you budget.
Pick it if your clients send a lot of email next to LinkedIn and you want one flat bundle for the whole roster.
4. CampaignStack (ours)
This is our product, so read this entry with that in mind.
Why it's fourth.
- Email sends only from Google accounts (Gmail or Google Workspace). We don't send from Outlook or SMTP.
- Email steps have no per-send review. What you review is the campaign's email copy.
- It covers LinkedIn and email only, with no calls, SMS or WhatsApp.
- Pricing is per workspace, and agencies run one workspace per client, so each client is its own plan.
- No white-label: no custom domain, no client login and no branded campaign reports.
What it does well. Each LinkedIn account gets its own static residential IP, used by that account only and matched to its country where available. Each account also has its own encrypted browser profile. LinkedIn messages wait in a review queue by default, and follow-ups are always reviewed. You can switch a workflow to auto mode, where first messages and replies go out without review.
The weekly cap on connection requests is 100, 150 or 200 depending on the LinkedIn plan, and the real daily maximum works out at 15, 22 or 29. Under 300 connections, an account sends no connection requests or new messages, only replies to people who wrote first. New accounts warm up from 10% of their budget, and repeated warnings pause one kind of action on one account. Our safety page publishes the weekly caps and the daily formula.
Each workspace keeps its own campaigns, leads and do-not-contact list. On the paid plan there's no cap on LinkedIn accounts, Google accounts or teammates per workspace.
Pick it if most of your clients bring more than one LinkedIn account, you want LinkedIn messages reviewed by default, and Google mailboxes cover your email. Our agency page shows how workspaces map to clients.
5. Grinfi
What it does well. Each profile runs in a cloud anti-detect browser through its own assigned proxy, and Grinfi asks that the proxy match where the owner usually logs in. Limits recalculate daily from each profile's health, and warm-up is automatic. Any step can run in Manual mode, which holds it for a check before it sends. The free trial lasts 7 days and needs no card.
The catch. The cheaper Send plan has no email, so LinkedIn plus email starts on Enrich, which includes 3 email inboxes per seat. One seat is one LinkedIn account. We found no agency or white-label features on the pages we read. The per-seat price drops from 5 seats.
Pick it if you want a check on any step you choose and limits that adjust to each account.
6. lemlist
What it does well. lemlist has the strongest email side here. It sends through Google, Microsoft and SMTP, includes lemwarm warm-up on every plan and gives each user 5 senders. Multichannel adds SMS, a call dialer and a WhatsApp add-on. Leads can wait in a Launch section until you review them, and separate teams keep each client's data and billing apart.
The catch. LinkedIn automation needs a Chrome extension and "relies on the browser session". Each lemlist account connects one LinkedIn account, so ten client accounts means ten seats. Limits top out at 20 connection invites a day and 100 actions a day across all types. The Email plan has no LinkedIn steps. We found no white-label.
Pick it if email is most of your volume and LinkedIn is a supporting channel on a few accounts.
7. Expandi
What it does well. Expandi is cloud software with a dedicated IP from a country you pick. Connection requests, messages and email follow-ups live in one sequence. The Agency plan (custom, 10+ seats) lets you run Expandi under your own brand with reports for clients.
The catch. The dedicated IP comes from a data center. You read email replies in the connected mailbox, not in Expandi. We found no in-app review queue. The pricing page never says what a seat covers, and the agency price is custom.
Pick it if white-label is a must and you have 10 or more seats to fill.
8. Waalaxy
What it does well. One Waalaxy subscription can manage several client accounts, and paid plans run 100% in the cloud. Business puts LinkedIn and email in the same campaign, with 800 invites a month.
The catch. Up to 5 users share each fixed IP, and they are VPN IPs. LinkedIn plus email is Business only, and the pages we read don't document review on regular sequences. On white-label, Waalaxy's answer is "No, we don't offer white-label."
Pick it if you want to start fast on a handful of accounts and don't need branded reports.
Not on the list, and why
- Apollo. Its LinkedIn steps are manual tasks: "Apollo doesn't automatically complete LinkedIn tasks for you." It's great for sourcing, but it doesn't automate LinkedIn.
- HeyReach. Email runs through its Instantly and Smartlead integrations, in separate sequences "logically connected via lead status", so LinkedIn and email don't share one sequence.
- Salesflow. It combines LinkedIn and email in one "Dynamic Outreach" campaign, but we couldn't read its pricing page on the day we checked, so it isn't ranked.
A scenario: count the units before the prices
This agency is made up, to show how pricing units count. Say it runs 6 clients, and each client brings 2 LinkedIn accounts. That's 12 accounts. The table counts the pricing units each tool needs, read from its own pages.
| Tool | What one unit covers | Units for 12 accounts |
|---|---|---|
| La Growth Machine | "An identity equals a license" | 12 identities, past Basic's "Up to 3 identities" |
| Reply.io (Multichannel) | 1 LinkedIn account per user included | 12 users |
| lemlist | "Each lemlist account can only connect to a single LinkedIn account" | 12 seats |
| Grinfi | "One LinkedIn account per seat" | 12 seats |
| Waalaxy | "one Waalaxy license = one LinkedIn account" | 12 licenses |
| CampaignStack (paid) | One workspace per client, no cap on LinkedIn accounts | 6 workspaces |
| Skylead, Expandi | Their pricing pages don't define what a seat covers | Ask them |
Change the roster and the counts move in different ways. At 1 account per client, every per-account tool drops to 6 units and CampaignStack stays at 6 workspaces. At 3 accounts per client, the per-account tools need 18 units; CampaignStack still needs 6.
Neither unit wins in general. A workspace is a bigger unit than a seat, so read the "Starts at" column with the unit in mind. The answer depends on your roster, which is why the table puts the unit next to the price. Count accounts per client before you count clients.
The free plan runs one workspace with one LinkedIn account and one Google account, with LinkedIn messages waiting for your review.
Run one client free: 1 LinkedIn and 1 Google accountWhat to watch out for
Automation breaks LinkedIn's rules, whichever tool you pick. LinkedIn's User Agreement (section 8.2) bans "bots or other unauthorized automated methods to access the Services, add or download contacts, send or redirect messages", and using "another's account (such as sharing log-in credentials or copying cookies)". Every tool here automates LinkedIn, ours included, so none can promise zero restrictions.
Extension or cloud. A Chrome extension works through a browser session on someone's machine. A cloud tool runs a remote browser on a server and an IP of its choosing. Cloud isn't automatically better. The next question is the IP.
Who else is on the IP. Read the help center, not the homepage, and ask two things: is the IP dedicated to one account or shared, and is it residential, mobile, data center or VPN?
The pricing unit. "Per user", "per seat", "per LinkedIn account", "per identity" and "per workspace" are five different things. Ask each vendor what one unit covers: how many LinkedIn accounts, how many mailboxes, how many clients. Expandi's page doesn't define a seat at all.
What doesn't migrate. Sequences, stats and A/B history stay behind; the FAQ below and our guide to leaving any outreach tool cover the move.
FAQ
What is a multichannel outreach tool?
A multichannel outreach tool runs one sequence that mixes LinkedIn steps (profile visit, connection request, message) and email steps for the same lead, and stops every channel as soon as that lead replies on any of them. Two separate sequences, or LinkedIn steps left as manual tasks, don't count.
Which tools run LinkedIn and email in the same sequence?
Checked in October 2026, eight tools do: La Growth Machine, Reply.io, Skylead, CampaignStack, Grinfi (from its Enrich plan), lemlist (on Multichannel), Expandi, and Waalaxy on its Business plan. Apollo's LinkedIn steps are manual tasks, and HeyReach runs email through its Instantly and Smartlead integrations as separate sequences, so neither runs both in one sequence on its own.
Is a cloud tool less risky than a Chrome extension for LinkedIn?
A Chrome extension works through a browser session on someone's machine. A cloud tool runs a remote browser from an IP the vendor provides, and that IP is the bigger question: dedicated or shared (Waalaxy allows up to 5 users per VPN IP), and residential, 5G mobile or data center. No setup removes the risk, because LinkedIn's User Agreement (section 8.2) bans automated access.
Can I run several client LinkedIn accounts from one tool?
Yes, all eight ranked tools run several LinkedIn accounts. What differs is the pricing unit (per user, per seat, per LinkedIn account, per identity or per workspace) and how each client's data is kept apart: separate teams in lemlist, agency dashboards in Reply.io and Skylead, one workspace per client in CampaignStack.
How are multichannel outreach tools priced?
By one of five units: per user, per seat, per LinkedIn account, per identity or per workspace, each billed monthly or annually. What one unit covers differs by vendor, so ask how many LinkedIn accounts, mailboxes and clients it includes. The "Starts at" column in the ranking above gives each tool's cheapest plan with LinkedIn and email, its unit and billing basis, checked October 2026.
Can I approve messages before they reach a client's prospect?
In most of these tools, yes: La Growth Machine can hold a LinkedIn message or email step for a manual check, Grinfi can hold any step in Manual mode, lemlist holds leads for review before launch, Reply.io lets you preview LinkedIn messages, and Skylead reviews AI SDR replies in semi-automatic mode. CampaignStack reviews LinkedIn messages by default, but email steps get no per-send review; you review the campaign's email copy instead.
Can I move my existing sequences to a new outreach tool?
Not automatically. CampaignStack doesn't import another tool's sequences, and none of the vendor pages we read mention an importer, so you export every step, delay and A/B variant and rebuild them by hand. Import your do-not-contact list first: in CampaignStack it becomes a workspace exclusion list matched on LinkedIn profile and email, and checked again at every send. Stats and A/B history stay behind, and pending invitations stay on the LinkedIn account, so check them before you restart. Run the first rebuilt campaign in review mode.
Do I still need a separate cold email tool?
It depends on your email volume and providers. Skylead connects as many email accounts as you like at no extra cost, and lemlist sends through Google, Microsoft and SMTP. CampaignStack sends only from Google accounts, with daily limits that grow with each mailbox's age up to 400 a day for personal Gmail and 1,600 for Google Workspace, so heavy cold email may still need its own tool.
Takeaway
Before you compare features, write down how many clients you run and how many LinkedIn accounts each one brings, then count that roster in each tool's own unit. Next, ask every vendor which IP a client's session leaves from and whether a person can approve a message first. Those two answers matter more on a client's account than any channel count.
