Cold email buyers add one second channel in practice, and it is LinkedIn. The fastest-growing company in this layer is HeyReach, which went from $2M ARR in October 2024 to $17M in September 2026 (founder-reported, via a LinkedIn post compiled by arr.club). It did not do that by replacing the email sequencer. It plugs into one: HeyReach lists native integrations with Instantly, Smartlead and EmailBison, and its founder describes Clay + Smartlead + HeyReach as the agency "holy trio".
The catch is that LinkedIn is not an open protocol. On 25 March 2026 LinkedIn removed HeyReach's company page and restricted its executives' profiles. Every LinkedIn automation business is built on a platform that forbids it in its terms.
LinkedIn's enforcement, 2025–2026
| Date | Action | Source |
|---|---|---|
| Jan 2025 | LinkedIn files suit against Proxycurl over scraping and fake accounts; resolved Jul 2025 | LeadGenius timeline |
| Jan 2025 | French CNIL action against Kaspr over contact data collected from LinkedIn | LeadGenius timeline |
| Mar 2025 | Apollo.io and Seamless.AI company pages removed; Apollo's back by Jul 2026 | LeadGenius timeline |
| 6 Oct 2025 | LinkedIn sues ProAPIs in N.D. Cal., alleging "hundreds if not thousands of new accounts per day" and scraping sold at up to $15,000/month | Security Affairs |
| 25 Mar 2026 | HeyReach company page removed; CEO, CTO, CRO and CMO profiles restricted | HeyReach |
The pattern: LinkedIn moved from data scrapers to automation vendors, and from user-level restrictions to brand-level takedowns. HeyReach says customer campaigns were untouched and that its users sent 50M+ connection requests at 21.3% acceptance afterwards (HeyReach's account). That is plausible: removing a company page does not touch the session cookies customers' accounts run on. It is also the cheapest move LinkedIn has; the expensive ones are lawsuits and detection changes, and it has made both against other vendors.
Account-level risk numbers in circulation come from competitors. Valley cites a Northlight.ai analysis that ~40% of accounts on "non-compliant" tools were restricted in Q1 2026; Valley itself claims "zero account restrictions across 1,000+ accounts in 2.5 years". Neither is independently verifiable.
The practical limits
Practitioner guidance has converged: roughly 100–200 connection requests per week per account, ~20–25 a day ramped (Valley, updated Aug 2026), and 20–30 a day (Closely, Feb 2026). Waalaxy's plans cap at 300 or 800 invites a month. Detection keys on inhuman speed, 24/7 activity, datacenter IPs and extension signatures (Valley). LinkedIn does not publish an official number.
This is why agencies rotate senders. At 100–200 invites a week, one LinkedIn account reaches roughly 400–800 new people a month; reaching 10,000 needs 12–25 accounts, each a real person's profile. Sender rotation, pricing per sender and proxy-per-account are the core product, not features.
LinkedIn tools and prices
All as shown on vendor pages or cited reviews, October 2026 unless dated.
| Tool | Entry price | Model | Position |
|---|---|---|---|
| HeyReach | $79/sender/mo; $999/mo for 25; $2,999/mo for up to 300 | Per sender, flat tiers | Agencies; integrates with sequencers |
| Expandi | $99/seat/mo ($79 annual) | Per seat; agency custom at 10+ | Safety-first single-account users |
| Waalaxy | €19–69/user/mo | Per user; yearly −50% | Freelancers, SMB, France |
| Dripify | $39–79/mo annual (Closely, Feb 2026) | Per user | Budget |
| La Growth Machine | €60/identity/mo annual (Basic) | Per identity | LinkedIn + email + calls + X |
| Valley | $199/seat/mo; DFY $1,499/mo | Per seat, AI-heavy | AI SDR on LinkedIn |
| Snov.io | $69/mo per LinkedIn slot add-on | Add-on | Bundled into sequencer |
HeyReach's Unlimited tier works out to ~$10 per sender at the 300 cap (Valley's arithmetic). Expandi charges ~$79–99 for one. That price gap, not features, explains which tool agencies run.
How sequencers bundle it
| Sequencer | Channels beyond email (Oct 2026) |
|---|---|
| lemlist | Multichannel plan $87/mo annual: LinkedIn, SMS, WhatsApp add-on, dialer |
| Saleshandy | Email, calls, LinkedIn, WhatsApp on all plans |
| La Growth Machine | LinkedIn, email, calls; X on Ultimate |
| Smartlead | SmartDialer add-on; LinkedIn via HeyReach integration |
| Instantly | LinkedIn via HeyReach integration (HeyReach) |
The split is clear. Classic sequencers (lemlist, Saleshandy, LGM) build LinkedIn steps in. The volume sequencers (Instantly, Smartlead, EmailBison) leave it to HeyReach and integrate. The volume players carry less platform risk; the classic players own more of the workflow. See Multichannel steps for the feature view.
Calls, SMS, WhatsApp, video, mail
Cold calling sits upmarket. Nooks (parallel AI dialer, sequencing, coaching; "1,800+ teams") and Orum (9-seat minimum, unlimited dials, 160+ countries) both hide pricing behind a demo. Nooks now pitches its own sequencing as a replacement for "Outreach, Salesloft, Apollo sequencing". This is the In-house SDR teams budget, not the agency one.
SMS and WhatsApp appear as add-ons in lemlist and Saleshandy. For an EU sender, unsolicited B2B SMS is a harder legal case than email; see GDPR and ePrivacy and EU/EEA country matrix.
Video is a personalisation layer. Sendspark prices by "dynamic video minutes": $49/mo for 100 up to $699 for 3,000, with a Smartlead integration on Growth and above. Expandi integrates Sendspark and Hyperize.
Direct mail (Sendoso, Reachdesk, Postal and similar) was not researched in this pass. Nooks and Orum funding and seat prices were not verified.
What this means for an entrant
- Integrate LinkedIn, do not build it. HeyReach took the LinkedIn risk and the $17M of ARR. A sequencer that builds its own LinkedIn bot inherits LinkedIn's legal department. Ship a first-class HeyReach (and Unipile-style) integration with shared lead state and stop-on-reply across channels.
- Own the shared inbox and the lead state. The value in multichannel is knowing that a lead replied on LinkedIn and stopping the email follow-up. Whoever holds that state holds the customer; see Replies, booking and handoff and Unified inbox (Unibox).
- Price for agencies' sender counts. Agencies compare per-sender cost. HeyReach's ~$10–40 per sender is the reference point if you ever bundle LinkedIn.
- Skip calls and SMS at launch. Dialers are an SDR-team product with demo-gated pricing; SMS carries legal exposure in the EU. Neither is what a cold-email buyer churns over.
- Watch LinkedIn, not competitors. The single largest risk in this layer is a LinkedIn detection change or lawsuit against an integration partner. Build so that losing the LinkedIn channel costs a feature, not the business. See Platform liability: what the sequencer itself risks and the openings.
