Dux-Soup

Dux-Soup is a LinkedIn automation tool that sends connection requests, messages and follow-ups for you in multi-step campaigns. The product is now called STACKED. It runs as a desktop app for Mac and Windows or as a cloud service, from $41.25 per seat per month billed annually. Automation of this kind goes against LinkedIn's rules, so accounts that use it can be restricted.

Who is Dux-Soup for?

Dux-Soup suits people who prospect heavily on LinkedIn: freelance sellers, SDR teams, recruiters and agencies running outreach for clients. Its website has separate pages for individuals, teams and agencies, and for industries such as recruitment, consulting and SaaS. Teams that need multichannel sequences with email and calls, or that cannot risk a LinkedIn account restriction, usually choose a different approach.

What does Dux-Soup do?

Drip campaigns

A campaign chains steps such as visiting a profile, sending a connection request and following up with messages. The pricing page lists up to 12 action types. Teams with two or more seats can run shared campaigns.

AI-personalised messages

STACKED connects to ChatGPT, Claude and Gemini to write messages tailored to each prospect, so a campaign does not send the same text to everyone.

Inbox, insights and lead management

Replies from LinkedIn, Sales Navigator and Recruiter land in one inbox. Campaign insights show response rates by message, step and audience. Contacts can be managed and exported, and two-way integrations sync activity with HubSpot, Salesforce, Pipedrive, Freshsales, HighLevel and SharpSpring, or with other tools through Zapier and Make.

Safety controls

Dux-Soup sets default daily limits for visits, connection requests and messages based on your LinkedIn account type. It randomises activity, runs only in working hours you set and pauses when you reach LinkedIn's weekly invite limit.

Is Dux-Soup allowed on LinkedIn?

LinkedIn's help centre says it does not permit third-party software, bots or browser extensions that automate activity on the site, and that members who use them risk having their accounts restricted or shut down. Using Dux-Soup is not illegal, but it breaks LinkedIn's User Agreement. The safety controls lower the chance of being flagged; they do not make automation permitted.

How much does Dux-Soup cost?

Prices checked on 1 November 2026 on the Dux-Soup pricing page, per seat, in dollars:

The local plan runs on your own computer, so it only works while that computer is on. The cloud plan runs on Dux-Soup's servers. The pricing page lists no free plan and does not mention a free trial.

What do users say about Dux-Soup?

On G2 and Capterra, reviewers often say Dux-Soup saves time on repetitive prospecting, praise its campaign sequencing and unlimited campaigns, and mention helpful support.

The common complaints are a learning curve when setting up campaigns, an interface some call dated or slow, and the risk of LinkedIn warnings or restrictions. Some reviewers mention high resource use on their computer, and a few describe billing or refund problems.

When should you choose an alternative?

• You want to stay within LinkedIn's rules. Use LinkedIn Sales Navigator and do the outreach by hand.
• You want to compare other LinkedIn automation tools. See Expandi or Linked Helper.
• You want multichannel sequences with email. Look at lemlist or Reply.io.
