Where they pull apart

Dux-Soup

Stands out: The Chrome LinkedIn workhorse (STACKED local from $41.25) for list actions, not a pretty cloud sequencer.

Watch out: STACKED local is visit/connect automation, not a full cloud inbox. STACKED cloud is $74.17 annual. LinkedIn ToS still applies.

Not the right fit for

  • Teams that need cloud, not Chrome
  • Enterprises that refuse automation
  • People who want email sequences in the same login

Prosp

Stands out: LinkedIn voice notes plus AI connection messages, not another email box farm.

Watch out: No MCP or API. Billing runs every four weeks, not monthly, and a free proxy is included per account.

Not the right fit for

  • Teams that need email warmup and a unibox
  • Buyers who require MCP

Pros and cons

Dux-Soup

  • Among the cheapest public LinkedIn automation seats
  • Free trial on the plans page
  • STACKED cloud exists if you outgrow Chrome
  • Chrome runtime and ToS risk
  • STACKED local is not a full sequencer
  • Email is not the product

Prosp

  • LinkedIn voice notes, not just text
  • Per-account price drops sharply at volume
  • Free residential proxy for each account
  • No MCP or API
  • Billed every four weeks, so thirteen payments a year
  • LinkedIn only, so email needs a second tool
