10 Marketing Automation Workflow Templates for B2B SaaS Companies Transitioning from Legacy CRMs

Phase 1: Critical Revenue Workflows

1. Demo Request Response Automation

The goal of a demo request response automation workflow is to immediately respond to and schedule demo requests.

HubSpot setup:

Trigger: Form submission on demo request page
Actions: Send instant confirmation email, create deal, assign to sales rep based on territory, add to “Demo Requested” sequence
Enhancement: Use HubSpot’s meeting scheduling tool integration

Time to implement: 2-4 hours

Why first: Highest conversion rate touchpoint
Revenue risk: Any delay in demo scheduling directly loses deals
Migration complexity: Low — straightforward trigger/action setup

Why it matters: Demo requests have the highest conversion rates, so any delay in responding to demo requests directly impacts revenue.

2. Sales Qualified Lead (SQL) Handoff Workflow

Purpose: Seamless transition from marketing to sales

HubSpot setup:

Trigger: Lead score reaches SQL threshold OR specific action taken (pricing page visit + demo request)
Actions: Assign to sales rep, send internal notification, add to sales sequence, schedule follow-up reminder
SLA: Automatic escalation if no sales contact within 24 hours

Time to implement: 2-4 hours

Why second: Maintains marketing-to-sales velocity
Revenue risk: Breaks the entire lead pipeline if not working
Critical factor: Requires alignment between marketing and sales teams

Critical success factor: This workflow requires tight coordination between marketing and sales teams during migration.

3. Lead Lifecycle Progression Workflow

The purpose of a lead lifecycle progression workflow is to automatically move leads through your funnel stages.

HubSpot setup:

Trigger: Contact property changes (Lead Score, Engagement Level, or Demo Request)
Actions: Update lifecycle stage, assign lead owner, send internal notifications
Key feature: Use HubSpot’s native lead scoring vs. recreating complex legacy CRM scoring rules

Time to implement: 6-10 hours
