Best in class for programmatic LinkedIn and multichannel messaging from Claude Code. One credential per workspace, full API access on the starter plan, webhooks instead of polling.
Unipile is a unified messaging API. One SDK, one credential per workspace, and you can send and receive on LinkedIn, WhatsApp, Instagram, Telegram, plus email through Gmail, Outlook, and IMAP, plus calendar through Google and Microsoft. Instead of wiring six different messaging APIs and writing six different webhook handlers, you authenticate once and call the same endpoints across channels.
For Yalc that matters because the operating system is channel agnostic by design. The same prompt ("draft and send a follow up to everyone who didn't reply within 4 days") should run regardless of where the conversation lives. Unipile is the layer that makes that possible without writing per channel adapters.
Unipile sits at the **send** node in Yalc's GTM topology. But unlike most send layer tools, it doubles as a **listen** node because the same API surface returns inbox state, reactions, and reply threads. That dual role is what makes it foundational rather than swappable.
Unipile is the messaging fabric for outbound. It receives drafts from upstream (your sequencer, your one off generator, your reply assistant) and pushes them to whichever channel the recipient prefers. Most commonly LinkedIn for cold outreach, WhatsApp for warm touchpoints, email for documents and meeting notes.

Yalc ships a first party Unipile skill that wraps the CLI and exposes high level verbs (send-invite, list-posts, list-reactors, send-dm). The skill handles credential rotation, per account rate limiting, and Notion writeback automatically.
✓ Yalc skill available. View on GitHub.Unipile prices per linked account. The first plan starts at €49 / $55 per month and includes up to 10 connected accounts. Beyond that, pricing is degressive: about $5.50 per account from 11 to 50 accounts, dropping further at higher volume. The example on their pricing page is concrete: 3 emails plus 2 LinkedIn plus 6 WhatsApp equals 11 accounts at €5 each, or €55 a month.
What's included in every plan: full API access, unlimited usage (only the upstream provider limits apply), and a 7 day free trial with no credit card. That's a meaningful cost advantage versus per action pricing on PhantomBuster or per seat caps on HeyReach.
Up to 10 linked accounts. Right for solo operators and small teams.
Per account from 11 to 50. Right for a 2 to 5 person team running parallel sequences across multiple LinkedIn or email accounts.
Pricing drops further at 51 to 200, 201 to 1k, and 1k to 5k account brackets. Above 5k accounts is custom.
Unipile authenticates on behalf of the underlying LinkedIn account, so any view that account has access to is available via the API. If your LinkedIn login has Sales Navigator, Unipile can act on Sales Navigator queries. If not, it can't.
Not by itself. Account risk on LinkedIn comes from behavioral patterns (volume, timing, actions per day) regardless of which tool you use. Unipile respects safe send rates by default. The risk is when you push the volume past what a human could plausibly do.
PhantomBuster runs per action "phantoms" and you pay per scrape. Unipile is API first with flat per account pricing and unlimited usage on every plan. For systematic recurring workflows, Unipile is meaningfully cheaper and faster. For one off scrapes, PhantomBuster's UI is easier.
Yes, but check WhatsApp Business policies. WhatsApp restricts unsolicited business messaging more strictly than LinkedIn. Unipile is the right plumbing. The policy compliance is on you.
You register a webhook endpoint per workspace. Unipile POSTs new messages, reactions, and connection events as they happen. Yalc's Unipile skill includes a webhook receiver that writes events to Notion or your CRM with no polling.
Each Unipile plan counts one connected account as one billable unit. So 3 email accounts plus 2 LinkedIn accounts plus 6 WhatsApp accounts equals 11 accounts. The first 10 are bundled into the starter plan at $55 a month. Anything above is roughly $5.50 per account, dropping at higher volume.
