Email Marketing

When to Use

• Building a welcome sequence for new signups or lead magnet downloads.
• Designing a lead nurture sequence to move prospects toward conversion.
• Creating a re-engagement campaign for inactive users or subscribers.
• Writing an onboarding email series that drives product activation.
• Planning a newsletter cadence and format.
• Optimizing existing sequences for open rate, click rate, or conversion.

Context Required

• From startup-context: product description, ICP, value proposition, tone of voice, current user journey stages, key activation metrics.
• From the user: sequence type needed (welcome, nurture, re-engagement, onboarding, post-purchase, educational), audience context (who they are, what triggered entry, relationship stage), current email list size and segments, existing sequences (if optimizing), email platform in use, primary conversion action, any existing performance data.

Workflow

1. Define the sequence goal -- Every sequence gets one job. Map it to a specific outcome:
   • Welcome: activate, build trust, convert
   • Nurture: educate, build desire, drive trial/demo/purchase
   • Re-engagement: reactivate or clean the list
   • Onboarding: drive users to key activation milestones (coordinate with in-app messaging -- email supports, does not duplicate)
   • Newsletter: maintain top-of-mind, drive traffic, build relationship
2. Map the sequence arc -- Plan the emotional and logical progression across emails:
   • Welcome (5-7 emails, 12-14 days): Deliver value and quick win, origin story/connection, educational content on their pain, social proof/case study, address #1 objection, feature highlight, conversion ask with reason to act now.
   • Lead nurture (6-8 emails, 2-3 weeks): Lead magnet delivery, topic expansion, problem deepening, solution framework, case study, differentiation, objection handling, direct offer.
   • Re-engagement (3-4 emails, 2 weeks, triggered at 30-60 days inactivity): Check-in, value reminder, incentive, last chance and list cleanup.
   • Onboarding (5-7 emails, 14 days): Activate, guide to aha moment, feature education, milestone celebration, upgrade prompt.
3. Write each email using One Email, One Job -- Each email has one primary message and one call to action. No competing CTAs, no kitchen-sink emails.
4. Apply the email copy structure:
   • Hook (first 1-2 lines): Open with a question, surprising fact, or relatable scenario. This determines whether they keep reading.
   • Context (2-3 lines): Bridge from hook to value. Why does this matter to them right now?
   • Value (body): Deliver the insight, story, resource, or proof.
   • CTA (final 1-2 lines): Clear, specific, single action. Button for transactional CTAs, text link for content CTAs.
   • Formatting: Short paragraphs (1-3 sentences), generous whitespace, bullet points where helpful, mobile-first. Conversational tone, active voice.
5. Optimize subject lines -- Write 3 variants per email:
   • Keep under 40-60 characters for mobile
   • Patterns: questions, how-tos, numbers, direct statements, story teases
   • Clear beats clever, specific beats vague
   • Avoid spam triggers (ALL CAPS, excessive punctuation, "free")
   • Preview text (90-140 characters) is the second subject line -- write it deliberately, do not repeat the subject
6. Set timing and triggers -- Welcome email sends immediately. Early sequence emails 1-2 days apart. Nurture phase 2-4 days apart. Long-term weekly or bi-weekly. Define behavior-triggered branching where relevant.
7. Plan measurement -- Define success metrics per email: open rate, click rate, reply rate, conversion rate. B2B SaaS benchmarks: 25-35% open, 3-5% click, 1-3% conversion.

Output Format

• Sequence overview: name, entry trigger, goal, number of emails, timing, exit conditions.
• Per-email detail: number/purpose, send timing, 3 subject line options, preview text, full body copy (50-500 words depending on type), CTA, segment/conditions.
• Email length guidance: transactional 50-125 words, educational 150-300 words, story-driven 300-500 words. Anything over 500 words should be a blog post you link to.
• Segmentation logic and branching paths if applicable.

Frameworks & Best Practices

• One Email, One Job. The most common email mistake is trying to do too much. One message, one CTA. If you have two things to say, send two emails.
• Value Before Ask. Lead with usefulness, build trust through content before making the conversion ask. The sequence arc should front-load value.
• Relevance Over Volume. Fewer, better emails win. Segmentation by behavior (what they did) matters more than personalization by demographics (who they are).
• Plain text outperforms HTML for B2B. For B2B audiences, plain text emails (or minimal HTML that looks like plain text) consistently outperform heavily designed emails. They feel personal, not promotional.
• Send timing. Tuesday through Thursday, 9-11 AM in the recipient's timezone performs best on average, but the best send time is when your audience actually reads email. Test and adjust.
• List hygiene. Remove unengaged subscribers (no opens in 90 days for weekly senders, 180 days for monthly) after a re-engagement attempt. A smaller, engaged list outperforms a large, dead one.
• Reply-to matters. Use a real person's email as the reply-to address. Replies improve deliverability and create sales conversations.
• Unsubscribe is not the enemy. Make unsubscribing easy and obvious. People who cannot leave will mark you as spam, which damages deliverability for everyone on your list.
• Mobile-first writing. Over 60% of emails are opened on mobile. Short paragraphs, generous whitespace, thumb-sized buttons.

"We have 3,000 subscribers who haven't opened an email in 60 days. What do we do?"
