 Step 1: Define Your Funnel Stages

To build an effective SaaS email funnel, you need clear stages that align with user intent and behavior. Here’s a classic structure with SaaS-specific goals:

1. Awareness

   • User action: signs up for a lead magnet or newsletter

   • Goal: establish trust and introduce core value

2. Interest

   • User action: downloads ebook, joins webinar, or explores pricing

   • Goal: show use cases, features, and benefits

3. Trial / Activation

   • User action: starts a free trial or demo

   • Goal: drive product exploration and highlight quick-win moments.

4. Conversion

   • User action: trial expires or engagement drops

   • Goal: convert to paid user with compelling offer

5. Retention & Upsell

   • User action: onboarding completed or continued usage

   • Goal: retain, upsell, cross-sell, and solicit referrals

By mapping each stage, you can design targeted messaging that resonates with user mindset at that moment—driving them forward with timely, valuable communication.

Step 2: Set Up Lead Capture & Entry Points

Your funnel needs high-quality inputs. A few proven entry points:

• Free trials or freemium signup

• Downloadable content (ebooks, checklists, product guides)

• Calculator or self-assessment tool

• Webinars, AMA sessions, or demos

Implement these across:

• Homepage and product pages

• Blog content with CTA pop-ups or embedded forms

• Landing pages using targeted ads

Smooth integration with Yournotify or your CRM helps automate capture. Once someone signs up, they’re immediately funneled into your SaaS email marketing funnel, kicking off the welcome sequence and setting the stage for automated nurturing.

Step 3: Create the Right Email Sequences

A single email won’t cut it. Build a cohesive B2B SaaS email sequence across stages:

a. Welcome Sequence (3–5 emails)

• Email 1: Thanks + what to expect

• Email 2: Top 3 features and quick setup guide

• Email 3: Success story or testimonial

• Email 4: Invite to demo or next step

b. Trial Activation Sequence (5–7 emails)

• Day 1: Feature use-case + quick start tip

• Day 3: Encouragement + feature suggestion

• Day 5: Check-in + help resource link

• Day 7: Reminder that trial is ending

• Day 9: Final offer + FAQ

c. Product Education Sequence

• Feature spotlight + how-to video

• Best-practice guide + use case

• Invitation to join community or webinar

d. Conversion Sequence

• Expiry notice + pricing overview

• Offer incentive: discount or extended trial

• Social proof: customer success story

• Final reminder with scarcity messaging

e. Retention & Re-engagement Sequence

• Email usage stats + feature highlights

• Upgrade prompts or new feature announcements

• Personal check-in + feedback request

Each email should be concise, value-driven, and include a clear CTA—whether to login, book a demo, or upgrade.

 Step 5: Measure & Improve

What gets measured, gets improved. Your funnel strategy should be data-driven with key metrics at every stage:

Optimisations to implement:

• A/B test subject lines and CTAs (e.g., “Start using feature X” vs “Unlock feature X”)

• Track drop-off points and adjust messaging

• Update sequences with new case studies, webinar invites, analyst reports

• Use Yournotify analytics for clean reports and flow insights

• Common Mistakes to Avoid

1. Email Overload: Too many emails in short time = dissatisfied leads

2. Ignoring Behavior Data: One-size-fits-all messaging falls flat

3. Disconnected Content: Emails should align with users’ SaaS journey

4. No Mobile Optimization: Over 50% of emails are opened on mobile

5. Skipping Onboarding Support: People need help to reach activation
