Essential steps

The methodology that delivers real results

01

Building the list, with quality

Your list is your most valuable digital asset. Quality beats quantity.

  • A strong lead magnet: guide, template, calculator, checklist
  • A dedicated landing page for email capture
  • Double opt-in: fewer subscribers, more quality
  • Capture forms on all main pages
02

The welcome series

The first 3-7 emails set the relationship with the subscriber.

  • Email 1 (immediately): Deliver the lead magnet + brief introduction
  • Email 2 (day 2): Your best content
  • Email 3 (day 5): Case study / customer testimonial
  • Email 4 (day 8): Consulting offer or demo
03

The automations you need

Automated flows generate revenue 24/7 with no manual effort.

  • Abandoned cart: 3 emails, recover 15-25% of carts
  • Post-purchase: onboarding + review + upsell
  • Re-engagement: win back inactive contacts
  • Birthday/Anniversary: 5× conversion versus broadcast
04

Advanced segmentation

Relevant content means higher open rates and less spam.

  • Behavioural segments: clicks, opens, purchases
  • Demographic segments: industry, role, location
  • RFM scoring: Recency, Frequency, Monetary
  • Lead scoring: assign points per action
05

Design and copy

The email needs to look good and be quick to read.

  • Mobile-first: 64% of emails opened on phone
  • Subject line: under 50 characters, test A/B systematically
  • A single CTA per email, not 4 different buttons
  • Plaintext version enabled for deliverability
06

Deliverability and GDPR

Your emails need to reach the inbox, not spam.

  • SPF, DKIM, DMARC configured on the domain
  • Clean the list every 3 months (bounces + inactive)
  • Bounce rate under 2%, spam rate under 0.1%
  • One-click unsubscribe (mandatory under GDPR)
