What's the ideal number of emails in a drip sequence?

5–7 emails over 14–21 days is the sweet spot for most B2B and SaaS products. E-commerce can go longer. The sequence should end when you've delivered enough value to justify one clear ask — extending it beyond that point generates unsubscribes.

Which email platform should I use?

Klaviyo for e-commerce, ConvertKit or Mailchimp for content creators, ActiveCampaign for complex B2B automation. All support the sequence structure this prompt generates. The logic is platform-agnostic.

How do I A/B test across a sequence?

Test one variable per email, not across the whole sequence simultaneously. Start with Email 1 subject lines (highest leverage), then Email 3 body content (highest drop-off point), then CTAs. Most platforms support A/B testing at the individual email level.

Should I use Claude or ChatGPT for drip sequences?

Claude is stronger for drip sequences — it maintains a consistent voice across multiple emails and follows complex conditional logic (conversion events, branches) more faithfully. ChatGPT is faster for generating multiple subject line options.

📋 Prompt

You are an email marketing automation expert who has built drip sequences converting 25%+ of cold leads to customers.

Product/Service: [product or service]
Lead source: [lead source — free download/webinar/trial signup/contact form]
Goal: [campaign goal — book call/purchase/trial upgrade/re-engage]
Number of emails: [number of emails — 5, 7, or 10]

Task: Build a complete email drip sequence:

For EACH email:
- EMAIL [N] — Day [X]
- Goal: What this email achieves
- Subject line: 3 options (A/B/C)
- Preview text: Complements subject, under 90 chars
- Opening line: First sentence (not 'Hi [Name], hope you're well')
- Body: 150–200 words maximum
- Primary CTA: Button text + destination
- Timing note: Why this email sends on Day [X]

SEQUENCE LOGIC:
- Define the 'conversion event' that exits the subscriber early
- Define the re-engagement branch for non-openers after Email 3
- Define what happens after Email [N] if no conversion

💡 Pro Tips

The Day 0 email has the highest open rate of any email you'll ever send — deliver genuine value immediately, not a pitch

Email 3 is when most sequences lose people — it needs to be your most valuable email, not a sales push

Always define the exit condition (conversion event) before building — sequences without exit logic spam people who've already converted

Preview text is your second subject line — optimise it independently, don't repeat the subject

⚠️ Common Mistakes

Pitching in Email 1 — the sequence should earn the right to pitch by delivering value first

Same CTA in every email — vary the ask (read this, watch this, try this) to avoid pattern blindness

No plain-text version — many email clients render HTML poorly; always write a clean text version

No unsubscribe path that feels respectful — 'I'll stop emailing you' as a CTA beats 'manage preferences'
