CampaignStack vs Valley, compared for agencies

Valley sells the same idea CampaignStack does, warm people first, and it has shipped more of it than any LinkedIn tool in this set. The warm list is the part to copy: the people who viewed your profile, followed you or commented on your post are the best first list a founder can have, and Valley pulls them in without a search. The research layer reads blogs, newsletters, podcasts, press and funding across more than 200 sources per prospect, the drafts are trained to sound like the sender, and the inbox sorts replies into three buckets and drafts the answer. Native email from your own inbox arrived on every plan in August 2026, the trial is 7 days with nothing held back, and the public API has an OpenAPI schema an agent can read. For one person with one account and a Sales Navigator seat, the setup is complete.

Valley connects an account through its Chrome extension, which reads the session token out of a Chrome profile. The help center is firm that each LinkedIn account needs its own profile, and it keeps a page on fixing disconnections. The sends then run from Valley's cloud on a dedicated IP, which is the right architecture, but the capture step lives on somebody's laptop, and for an agency that laptop belongs to the client. The onboarding guide also says messages go out through the Sales Navigator inbox, so every account you run carries LinkedIn's own subscription on top.

Volume is a slider. Each campaign has a Daily Sequence Volume, default 25, and the help center publishes a sensible ramp: 5 to 10 a day the first week, 15 to 20 the second, the target by week four. It also says an account active for six months can skip the ramp, and that when several campaigns run, the total per day is the sum across them, which you add up yourself. CampaignStack computes the number: connection requests are capped at a share of the account's own connections under a weekly ceiling, warm-up starts at a tenth of the limit and grows with use, every workflow on the account draws from the same budget row, and the first security check pauses that action family on its own.

Valley's Autopilot toggle is per campaign, and its documentation recommends it for most users once they have read 10 to 15 messages by hand. After that, a message goes out the moment it is generated. The writing is good, which is exactly why the failure is quiet: a draft that reads well and gets a fact wrong looks identical to a draft that reads well and is right, and nobody is between the model and the send.

CampaignStack puts a critic there. Every draft is read against its full brief by a second model that returns one concrete objection or a pass; a failing draft is rewritten with the objection, and one that keeps failing is flagged into the review queue with the reason on the card. A zero-cost gate also fails any draft that copies six consecutive words from the playbook or offer context. Approve resumes the send; reject archives the draft and keeps listening. The result is that the auto-send mode is a mode you can actually leave on.

Valley's help center defines a seat as one active LinkedIn account, permanently bound to it. At $149 a month on quarterly billing, a client with three accounts is $447 a month before Sales Navigator, and the Scale tier for five seats or more is priced by sales. CampaignStack bills the client workspace: $299 a month, $249 on annual, however many accounts and teammates it holds, with 25,000 credits included. The lines cross at the second seat on either billing period, and the question for an agency is how many accounts the typical client brings.
