Outbound, inbound, and everything between.
WarmLane isn't a sending tool bolted to a CRM. Seven capabilities — including a 24/7 AI voice agent — in one platform, one set of numbers that match. Run it yourself, or have us run it for you.
Email, SMS, or WhatsApp — each on its own.
Every channel runs as its own independent campaign — cold email (B2B or B2C), SMS, or WhatsApp. Build a sequence in minutes; sends stop the moment a lead replies, unsubscribes, or signals negative intent. Channels stay separate, never mixed into one flow.
- ▸Up to 10 follow-up steps per campaign — most teams use 5–7
- ▸Per-step behavioural variants:
_clicked/_opened/_no_engagement - ▸Pool routing across multiple sending accounts with automatic quota distribution
- ▸Per-campaign daily caps + per-account warm-up curves
Replies in your voice — not GPT's.
Configure company description, product details, pricing, value props, FAQs, objection handlers, tone, and "don't mention" topics once. Every AI reply pulls from that ground truth — no off-brand answers, no hallucinated pricing.
- ▸Multi-provider AI — OpenAI, Claude, or DeepSeek; we provide it, or bring your own key
- ▸Test-drive the Brain before going live — see how it'd answer a sample inbound
- ▸Per-campaign tone overrides for friendly vs formal sequences
- ▸Intent routing: positive interest → propose slots, objection → answer with Brain, "stop" → suppress automatically
Calendar slots, not Calendly links.
When a lead replies positively, WarmLane proposes live availability from your calendar and books the meeting — no link click, no second tool, no "let me know what works". The lead picks a slot in the same conversation; it's on both calendars before the next send fires.
- ▸Google Calendar + Microsoft 365 — OAuth, two-way sync
- ▸Per-campaign meeting prefs — duration, working hours, working days, timezone
- ▸Automatic T-24h + T-1h reminders to both sides
- ▸No-show detection writes back to the sequence — re-engagement, not silent loss
Warm-ups, quarantine, suppression — handled.
Deliverability is a first-class feature, not an afterthought. Multi-account pools with automatic quota distribution and warm-up curves. Per-account quarantine on bounce spikes. Cross-tenant monitoring against AWS SES production thresholds (5% bounce / 0.1% complaint) so you see the problem before SES does.
- ▸Multi-account pools — distribute load across sending identities, automatic failover
- ▸Phone + email suppression lists, with STOP handling on SMS and one-click unsubscribe (RFC 8058)
- ▸Placement testing — seeded sends measure inbox vs spam before launch
- ▸CAN-SPAM footer with physical address + unsubscribe URL on every email
Roles, invites, seat limits.
Three roles — Admin, Team Member, Viewer. 7-day email invites that don't need an OTP (the invite link is the proof of email). Read-only access for stakeholders and managers without giving away the keys.
- ▸The workspace owner is immutable — can't be demoted or removed, ever
- ▸Tokenised mass-revocation — role change or removal invalidates outstanding JWTs in <15 seconds
- ▸"Leave workspace" self-service for non-owners — clean exit, no admin chaining
- ▸Append-only audit log of every team action — who invited / re-roled / removed whom, when, from where
Month-to-date usage, in your face.
Real-time counters for sends by channel, AI calls, subscribers — with a projected month-end from the day's pace. Stripe-metered overage with no surprise invoices. Self-serve checkout, billing portal, invoices.
- ▸Inform banner at ≥80% of any plan limit — sends keep going, overage is metered
- ▸Per-channel breakdown: B2B email, B2C email, SMS, WhatsApp — kept separate
- ▸Stripe meters report in real time — billing source of truth, no monthly reconciliation
- ▸Founder pricing — 50% off forever for the first 50 paying customers
Never miss a call — answered 24/7.
A 24/7 AI voice agent picks up every inbound call, answers questions about your business in your own words, qualifies the caller, and books the meeting straight onto your calendar. Built custom to how your business actually works — no missed leads, no after-hours gaps, no extra headcount.
- ▸Always on — answers nights, weekends, and the call spikes you'd otherwise miss
- ▸On-brand answers grounded in your offer, pricing, and FAQs
- ▸Qualifies + books the meeting straight onto your connected calendar
- ▸We provide the inbound number + AI — configured and tuned to your business
