Three Email Types: Welcome, Broadcast, and Evergreen — Each Serves a Different Function

The Framework

The Three Email Types from Allan Dib's Lean Marketing categorize every email your business sends into one of three functional categories. Each type has a different trigger, a different purpose, and a different optimization strategy. Most businesses conflate all three, sending the same kind of email to everyone regardless of context — which is why their email marketing underperforms.

The Three Types

1. Welcome Sequences (Triggered). Automatically sent when a new subscriber joins your list — typically through a lead magnet download, event registration, or form submission. The welcome sequence has the highest open rates of any email type (often 50-70%) because the subscriber is at peak engagement — they just took an action and expect to hear from you.

The welcome sequence serves three functions: deliver the promised value (the lead magnet, the confirmation, the access), establish the relationship (who you are, what to expect, how often you'll email), and begin the engagement arc (the Soap Opera Sequence if using narrative, or a value-based introduction series if using educational content).

Dib recommends 5-7 emails in the welcome sequence, sent over 7-14 days. The first email delivers the promised item immediately. Emails 2-5 deliver value and build relationship. Emails 6-7 introduce the core offer or CTA for the first time. This pacing respects the subscriber's attention while systematically building toward conversion.

2. Broadcasts (Scheduled). Sent to your entire list (or specific segments) on a regular schedule — weekly newsletters, announcement emails, promotional campaigns, and event invitations. Broadcasts maintain the ongoing relationship with your full subscriber base. They keep you top-of-mind, deliver regular value, and create periodic commercial opportunities.

Broadcasts have lower open rates than welcome sequences (typically 20-30%) because they compete with the subscriber's entire inbox on a regular basis. The quality of each broadcast determines whether the next one gets opened — every underwhelming broadcast reduces future engagement. Dib's Give:Ask Ratio (borrowed from Hormozi) applies: maintain at least 3:1 value-to-commercial content in broadcasts.

The Super Signature belongs in every broadcast — a permanent, low-pressure commercial footer that provides ongoing commercial presence without making any individual broadcast feel salesy.

3. Evergreen Sequences (Automated). Pre-written email sequences that run on a schedule relative to each subscriber's entry point, regardless of calendar date. Unlike broadcasts (sent to everyone on Tuesday), evergreen sequences send email #1 on day 1 of each subscriber's journey, email #2 on day 5, email #3 on day 12 — regardless of when they subscribed.

Evergreen sequences are the highest-leverage email type because they're written once and run forever. A 20-email evergreen sequence that nurtures subscribers over 90 days produces ongoing conversion without any new content creation. The investment is front-loaded; the returns are perpetual.

Evergreen sequences work best for: onboarding (systematic education about your methodology), nurture (gradual trust-building over weeks), and sales (presenting your offer at the optimal moment in the subscriber's engagement arc — typically after 2-4 weeks of value delivery).

How They Work Together

The three types form a complete email lifecycle:

Phase 1: Welcome Sequence captures new subscribers and delivers the initial value. Runs 7-14 days.

Phase 2: Evergreen Sequence takes over after the welcome sequence ends and nurtures over 30-90 days. Delivers systematic education, builds trust, and presents the core offer at the optimal time.

Phase 3: Broadcasts maintain the ongoing relationship after evergreen sequences complete. Weekly value delivery with periodic commercial opportunities via the Super Signature and occasional promotional broadcasts.

The transitions between phases are managed by CRM tagging (one of Dib's Five Essential CRM Functions): when a subscriber completes the welcome sequence, they're automatically enrolled in the evergreen sequence. When they complete the evergreen sequence, they're tagged for broadcast-only communication.

Cross-Library Connections

Hormozi's Warm Outreach from the Core Four in $100M Leads generates the subscribers that Welcome Sequences capture. Content and paid ads generate subscribers that the same sequences nurture. The Three Email Types provide the post-capture infrastructure that converts Hormozi's lead flow into customer relationships.

Dib's Four-Stage Email Mastery (Delivered → Opened → Read → Actioned) applies to all three types but with different typical failure points. Welcome sequences rarely fail at Stage 1-2 but sometimes fail at Stage 4 (weak CTAs). Broadcasts commonly fail at Stage 2 (subject line fatigue). Evergreen sequences rarely fail at Stage 2-3 but need monitoring for content decay over time.

Cialdini's commitment principle from Influence explains why the three-phase lifecycle converts: each opened email is a micro-commitment that compounds into consistency pressure. By the time the evergreen sequence presents the core offer, the subscriber has 15-25 micro-commitments invested in the relationship.

Implementation

  • Build your Welcome Sequence first (5-7 emails). This captures the highest-engagement moment and sets the relationship foundation.
  • Add Broadcasts second (weekly newsletter with Super Signature). This maintains the ongoing relationship.
  • Build Evergreen Sequences third (20+ emails over 60-90 days). This is the highest-leverage investment but requires the most upfront work.
  • Set up CRM transitions between the three phases. Subscribers should flow automatically from welcome → evergreen → broadcast.
  • Optimize each type separately using Four-Stage Email Mastery. Different types fail at different stages.
