The outcomes we design for

Stack overview

Orchestration: n8n handles triggers, branching, enrichment, retries, and logging.
CRM + SMS: GoHighLevel for sequences, inboxes, and number management.
Email: SendGrid/Mailgun with warmed domains and per-segment rate limits.
Enrichment: Clearbit/Apollo + NeverBounce for validation.
Analytics: ClickUp/Looker dashboards for replies, complaints, and pipeline.

Cadence design that actually converts

We build 2–3 cadences per segment: high-intent, mid-intent, nurture. Each cadence mixes short value emails, SMS nudges, and social-proof drops. Subject lines stay under 6 words; SMS stay under 250 characters. Every branch pauses when a reply is detected.

Behavioral triggers

Deliverability guardrails

We warm sending domains, rotate sender identities, and cap daily sends per segment. We validate every email, quarantine risky domains, and drop contacts that fail SMTP checks. Complaint and bounce rates are monitored every 30 minutes; sequences pause if thresholds trip.

Timeline to launch

Measuring success

We track reply rate, positive replies, meetings booked, revenue influenced, complaint/bounce rates, and time-to-first-touch. Weekly reports show pipeline impact and inbox health with clear next actions.

“We didn’t hire an SDR—we shipped an always-on system. Meetings rose 28% and complaints stayed under 0.1%.” — VP Growth, B2B services

Common mistakes to avoid

Playbook to copy

  1. Enrich + validate every lead before messaging.
  2. Tag intent (high/mid/low) and route to matching cadence.
  3. Cap sends per day; pause on complaints over 0.1%.
  4. Alert humans on replies; stop the bot when a human steps in.
  5. Review copy weekly; rotate subject lines monthly.

FAQ

Do you support WhatsApp?

Yes. We can add WhatsApp for certain regions with opt-in and template approvals.

How do you keep SMS compliant?

We honor quiet hours, include opt-out language, and register numbers where required (e.g., 10DLC in the US).

Can we A/B test?

Yes. We test subject lines, send times, and CTA placement. We default to 70/30 splits with auto-winners.

What if our data is messy?

We add a data-cleanup sprint: normalize phone/email, dedupe, and enrich missing fields before launch.
