Coldrig vs Skyp: infrastructure-plus-campaigns vs. a full GTM stack
Choose Skyp when the requirement is a done-for-you B2B GTM stack: AI-written email, LinkedIn outreach, a 650M+ contact database, buying-intent signals, and regulated-industry compliance guardrails, all in one dashboard-first product with a human support layer. Choose Coldrig when the requirement is narrower and agent-first: domains, mailboxes, warmup, campaigns, and replies as one API/MCP surface your own coding agent drives, without paying for lead data or LinkedIn you may not need. Skyp is the broader, more mature product; Coldrig is the smaller, cheaper, agent-native slice of it.
Fast decision table
| Requirement | Skyp | Coldrig |
|---|---|---|
| Managed domains, mailboxes, warmup | Yes — full done-for-you infra, SPF/DKIM/DMARC configured automatically | Yes — one setup_infrastructure call |
| MCP for coding agents | Native MCP server, included from the Pro tier ($149/mo) | Hosted streamable-HTTP MCP endpoint plus REST and npm CLI, included at every tier |
| Email + LinkedIn outreach | Both — coordinated multi-channel sequences | Email only |
| Lead / contact database | 650M+ verified contacts included from Pro; website-visitor ID and buying-intent signals at higher tiers | Not included — the customer's agent owns targeting and lead sourcing |
| AI-written copy | Every email individually written per prospect, per Skyp's own claim | Not included — the customer's agent owns copy |
| Regulated-industry compliance messaging | Explicitly claims guardrails for FDA, HIPAA, SEC, FINRA, FTC, or custom | CAN-SPAM-class suppression and unsubscribe enforced server-side; no regulated-industry-specific guardrail messaging |
| Support model | Human support chat (Pro+), white-glove onboarding (Team+), priority Slack (Growth) | No human support tier published yet — see support |
| Live real sending / production track record | Yes — an established, paying-customer product today | No — Coldrig is early access; the API, MCP endpoint, and sandbox are live, but real sending and a production deliverability record are not active yet (see FAQ) |
Where Skyp is honestly stronger
- Full GTM breadth. Email and LinkedIn outreach, a 650M+ contact database, website-visitor identification, and buying-intent signals in one platform — Coldrig has none of this and isn't trying to.
- AI copywriting included. Skyp claims to write every email uniquely per prospect; Coldrig deliberately stays an execution layer and leaves copy to the customer's own agent.
- Regulated-industry positioning. Explicit compliance-guardrail claims for FDA, HIPAA, SEC, FINRA, and FTC contexts are a real differentiator for those buyers, even though the underlying technical implementation isn't detailed on their public pages.
- Human support included. Chat support from the entry paid tier, white-glove onboarding, and priority Slack support at higher tiers — a more human-assisted product than Coldrig's current self-serve, agent-first model.
- A live, proven product today. Skyp has real paying customers and a production track record; Coldrig is early access with no real sending active yet. If "live, proven product" is a hard requirement right now, that alone should rule Coldrig out today — see the disclosure below.
Where Coldrig's design is different
- One tenant credential. A single bearer token covers domains, mailboxes, warmup, campaigns, and replies — no separate contact-database or intent-data product to configure.
- Narrower, cheaper scope. If lead sourcing, LinkedIn, and AI copywriting are already handled elsewhere (or by the customer's own agent), Coldrig doesn't charge for capacity that would go unused.
- No lead-database markup. Skyp's pricing bundles contact data and signals into every tier; Coldrig's formula is mailbox count only, so the price tracks infrastructure, not data access.
Pricing: what a mailbox actually costs
Skyp's plans are annual-billed by default (save ~20%; monthly billing runs higher — a prior same-day research pass recorded Pro at $199/mo, Team at $599/mo, and Growth at $1,499/mo on the monthly cadence). The figures below are the confirmed annual-effective prices from skyp.ai/pricing, live 2026-07-15.
| Plan | Price (annual) | Managed mailboxes included | Effective $/mailbox | Advertised send capacity |
|---|---|---|---|---|
| Skyp Pro | $149/mo | 3 (1 domain) | ≈$49.67 | ~1,500 emails/mo (self-reported) |
| Skyp Team | $499/mo | 10 (5 domains) | ≈$49.90 | ~5,000 emails/mo (self-reported) |
| Skyp Growth | $1,199/mo | 30 (15 domains) | ≈$39.97 | ~15,000 emails/mo (self-reported) |
| Coldrig, 5 mailboxes | $99/mo | 5 | $19.80 | No send quota |
| Coldrig, 10 mailboxes | $149/mo | 10 | $14.90 | No send quota |
| Coldrig, 30 mailboxes | $349/mo | 30 | $11.63 | No send quota |
On managed-mailbox cost alone, Coldrig runs at roughly a third of Skyp's effective $/mailbox at every comparable tier. That comparison is fair as far as it goes — but it isn't the whole product: Skyp's price also buys LinkedIn outreach, a contact database, AI copywriting, and (at Team+) intent signals, none of which Coldrig includes at any price. Coldrig has no send quota — sends are not the billing meter, bounded instead by warmup stage, mailbox health, and provider policy. Skyp publishes a self-reported monthly capacity estimate per tier (1,500 / 5,000 / 15,000) rather than a hard contractual cap; Coldrig's own conservative planning capacity is ≈3,300/mo at 5 mailboxes (non-contractual planning guidance, not a purchased allowance — see the calculator). Compare the whole stack you'd actually need, not the sticker price alone.
Bottom line
If the requirement is a full B2B GTM motion — email, LinkedIn, contact data, signals, regulated-industry guardrails, human support — Skyp is a mature, done-for-you product built for exactly that, and it's the closest shape to Coldrig of the vendors we've compared. If the requirement is narrower — an agent-driven infrastructure-and-campaign layer, without paying for lead data or LinkedIn — Coldrig's per-mailbox economics are meaningfully cheaper, but it's a smaller product doing a smaller job on purpose.
