Email Sequences
Plan and write email campaigns. Sequences (multi-message flows triggered by events) and broadcasts (one-off sends). Stack-agnostic. Works with any email service provider.
When to use
- Writing welcome and onboarding email sequences
- Planning lifecycle campaigns (activation, retention, win-back)
- Writing transactional emails (receipts, password resets, notifications)
- Newsletter design and writing
- Abandoned-cart or re-engagement flows
- Writing a one-off broadcast, launch announcement, or news email
- Drafting email subject lines and preview text for any send
When NOT to use
- Landing pages and conversion pages (use
landing-page-copy) - Long-form articles (use
content-and-copy) - Brand voice work (use
brand-voice) - Analytics setup for email (use
analytics-strategy)
Required inputs
- The audience (segment or list)
- The trigger or context (signup, purchase, abandonment, time-based, manual)
- The goal of the email or sequence
- Brand voice
- Any technical constraints (provider, deliverability requirements)
If the audience is undefined, define it before writing. Generic emails to "everyone" perform worse than targeted ones.
The framework: 6 sequence types
Most email programs run a handful of standard sequence patterns. Each has its own goals, structure, and pitfalls.
1. Welcome / onboarding
Triggered by signup. Goal: get the user to first value.
Typical structure (5 emails over 14 days):
- Email 1 (immediate): Welcome. Confirm they're in. State what happens next. Single CTA: the next obvious action.
- Email 2 (day 1 or 2): First-value step. Help them get to a quick win or core action.
- Email 3 (day 4 or 5): Education. Show them something they probably haven't discovered yet.
- Email 4 (day 8): Social proof. Customer story or use case relevant to their segment.
- Email 5 (day 14): Outcome reminder. Where they could be in 30/60/90 days. Soft commercial cue.
Common failure: Front-loading product features. Users don't care about features yet; they care about getting to value.
2. Lifecycle / activation
Time- or behavior-triggered. Goal: move users from signup to engaged user.
Patterns:
- Sent when a user completes a milestone (first project, first invite, first export)
- Or sent when a user has NOT completed a milestone after N days
- Each email targets a specific next step
Best practice: Trigger on behavior, not just time. A user who has done 3 onboarding steps doesn't need an email telling them to get started.
3. Retention / engagement
Ongoing. Goal: keep active users engaged.
Patterns:
- Newsletter (weekly or monthly)
- Product updates
- Tips and tutorials
- Customer-only content (community, behind-the-scenes)
Cadence rule: Frequency that earns the read, not frequency that fills the calendar. Weekly newsletter that is genuinely useful beats daily newsletter that gets archived.
4. Re-engagement / win-back
Triggered by inactivity. Goal: pull a lapsed user back.
Typical structure (3 emails):
- Email 1: "We miss you" framing or value reminder. What's new since they were last active.
- Email 2: Specific incentive (discount, feature unlock, content offer).
- Email 3: "Last call" or list-cleaning email. "We'll stop emailing you unless you click this."
Best practice: Honor the unsubscribe. Aggressive win-back damages deliverability. A clean list of engaged subscribers beats a large list of inactive ones.
5. Transactional
Triggered by actions: receipts, password resets, notifications, order confirmations, shipping updates.
Best practices:
- Confirm the action that triggered the email at the top
- Include all relevant detail without padding
- Use plain language ("Your order shipped" not "Your shipment notification")
- One primary CTA (track package, view receipt, view account)
- Subject line states the action ("Your receipt for order #12345")
Highest open rates of any email type. Use sparingly for marketing nudges; over-marketing transactional emails damages trust.
6. Broadcast
One-off sends. Announcements, launches, news, time-sensitive campaigns.
Best practices:
- Subject line earns the open
- Single clear message per send
- Specific audience targeting (do not blast the entire list for narrow announcements)
- Clear CTA in the first screen-height
- Mobile-optimized (most opens are mobile)
The 5 components of every email
Regardless of sequence type, every email has the same components.
1. Subject line
The deciding factor for whether the email gets opened.
Patterns:
- Specific ("Your week 1 progress: 3 of 5 steps done")
- Curiosity ("The mistake most teams make in week 2")
- Direct ("Your invoice #12345")
- Personal ("Quick question, [name]")
- Urgency ("Last day for the team plan discount") - use sparingly
Avoid:
- ALL CAPS
- Excessive punctuation (!!!)
- Click-bait that doesn't deliver
- Generic ("Newsletter #23")
Length: 30 to 50 characters. Mobile clients truncate longer.
2. Preview text (preheader)
The line that appears below or beside the subject in most email clients.
Best practice:
- Treat as the subject's wingman
- Add what the subject line couldn't fit
- Avoid wasting it on "View this email in browser"
- 50 to 90 characters
3. Opening
The first line of the email body. The reader is deciding whether to keep reading.
Strong openings:
- Reference the trigger ("You signed up yesterday for...")
- Get to the point ("Here's what changed this week...")
- Personal ("Saw your team just hit milestone X. Nice work.")
Weak openings:
- "I hope this email finds you well."
- "Welcome to our amazing platform."
- Long throat-clearing before the actual content
4. Body
The substance.
Length guide:
- Welcome and transactional: under 100 words
- Lifecycle and activation: 100 to 250 words
- Newsletter: 200 to 800 words depending on format
- Sales sequences: 250 to 500 words
Structure:
- One core message per email (avoid "while we have you...")
- Short paragraphs (2 to 3 lines)
- Bullets or lists when content is enumerable
- Mobile-first formatting
5. CTA
The action the email is asking for.
Best practices:
- One primary CTA per email (multiple CTAs split attention)
- Button or clearly-styled link, not buried in prose
- Action verb + specific outcome ("See your dashboard" not "Click here")
- Above the fold AND repeated at the end of longer emails
- Plain text link as a fallback for users who block buttons
Workflow
For a new sequence
- Define the trigger. What event starts this sequence? (Signup, purchase, abandonment, manual.)
- Define the goal. What does success look like at the end of the sequence?
- Map the journey. What does the recipient need to know, do, or feel between trigger and goal?
- Outline emails. One purpose per email. Sequence them across appropriate timing.
- Draft email 1. Subject, preview, opening, body, CTA.
- Draft remaining emails. Each builds on the previous.
- Test the sequence. Send to yourself. Read on mobile. Time the gaps.
- Set up triggers. Configure in the email service provider.
- Measure. Open rate, click rate, completion rate per email. Sequence completion rate.
For a single broadcast
- Define the audience. Specific segment, not the whole list.
- Define the goal. One thing this email accomplishes.
- Draft subject + preview. Generate 5 to 10 variations.
- Draft body. Single message, clear CTA.
- Test on mobile. Most opens are mobile.
- Schedule. Day and time matched to audience behavior.
- Measure. Open rate, click rate, downstream conversions.
Failure patterns
- Sending to "everyone." Generic broadcasts to the full list have lower engagement than targeted segments.
- Too many CTAs in one email. Splits attention. Pick one.
