Email & Lifecycle Marketing

Email is the highest-ROI channel in SaaS — when done right. This skill helps you design email sequences that drive activation, retention, and revenue with specific copy you can paste into your email tool.

If ABOUT-ME.md and/or MY-ICP.md exist in the project root, read them before writing emails. The "from" voice should match ABOUT-ME.md Communication Style — emails should sound like the founder, not a marketing department. The content should speak to MY-ICP.md — their pain, their goals, their language.

Core Principles

Every email must answer: "Why should I care about this right now?"
Behavioral triggers > time-based drips. React to what users DO, not how long they've been around.
One email, one goal, one CTA. Multiple CTAs = no CTA.
Subject lines determine whether your email is read. Body copy determines whether it's acted on.
Unsubscribes are better than spam complaints. Make it easy to leave.

Part 1: Professional Branded Email (Do This First)

Before you send a single marketing email, you need a professional email address. Sending from yourname@gmail.com kills credibility. You want hello@yourdomain.com — and you can set this up for free in under 30 minutes.

The Free Setup (Cloudflare + Gmail)

This is the 80/20 approach. You get a branded email address without paying for Google Workspace or managing an email server.

What you need:

A free Gmail account (you probably already have one)
Your domain on Cloudflare (free plan works — if your domain is elsewhere, transfer DNS to Cloudflare)

Step 1: Set up Cloudflare Email Routing (receiving mail)

Cloudflare Email Routing forwards hello@yourdomain.com to your personal Gmail — for free.

Go to Cloudflare dashboard > your domain > Email > Email Routing
Click "Get started" and add a destination address (your Gmail)
Verify your Gmail address when Cloudflare sends the confirmation
Create a route: hello@yourdomain.com → yourpersonal@gmail.com
Add a catch-all if you want (sends ANY @yourdomain.com address to your Gmail)

That's it. Emails to hello@yourdomain.com now arrive in your Gmail inbox.

Step 2: Send AS your branded address from Gmail

Receiving is only half the equation. You also want to reply FROM hello@yourdomain.com so recipients see your branded address, not your personal Gmail.

Option A — Use a free SMTP relay (most reliable):

Create a free account on Resend or Brevo (both have free tiers)
Verify your domain in their dashboard (they'll give you DNS records to add in Cloudflare)
Get your SMTP credentials from the relay service
In Gmail: Settings > Accounts > "Send mail as" > Add another email address
Enter hello@yourdomain.com, uncheck "Treat as alias"
Enter the SMTP server, port, username, and password from your relay service
Click the verification link Gmail sends to hello@yourdomain.com (which forwards to your Gmail)

Option B — ImprovMX ($10/year):

Handles both forwarding AND SMTP sending in one service
Simpler setup than Option A if you want to skip the relay configuration
Free tier available (forwarding only; sending requires paid plan)

Step 3: Set your branded address as the default

In Gmail: Settings > Accounts > "Send mail as" > make hello@yourdomain.com the default. Now every email you send comes from your branded address.

Email Security: SPF, DKIM, and DMARC

These three DNS records prevent attackers from spoofing your domain (sending fake emails that look like they come from you). They also dramatically improve deliverability — without them, your emails land in spam.

Why this matters for founders:

Without DMARC, anyone can send emails pretending to be @yourdomain.com
Phishing attacks using your domain destroy trust and can get your domain blacklisted
Gmail, Outlook, and Yahoo now require SPF and DKIM for bulk senders — even small senders benefit

What to set up (add these as DNS records in Cloudflare):

Record	What It Does	Priority
SPF	Declares which servers can send email for your domain	Must have
DKIM	Cryptographically signs your emails to prove they're authentic	Must have
DMARC	Tells receiving servers what to do with emails that fail SPF/DKIM checks	Must have

Your email forwarding service (Cloudflare) and SMTP relay (Resend/Brevo) will give you the exact DNS records to add. Follow their setup guides — they walk you through it.

DMARC record to start with (add as a TXT record for _dmarc.yourdomain.com):

v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com; pct=100

p=quarantine tells receiving servers to spam-folder emails that fail authentication (use p=reject once you're confident everything is configured correctly)
rua=mailto:... sends you aggregate reports about who's sending email from your domain

Verify your setup: Use MXToolbox or Google's Check MX to confirm SPF, DKIM, and DMARC are working.

When to Upgrade to Google Workspace

The free Cloudflare + Gmail setup works great for solo founders. Consider Google Workspace ($7/user/month) when:

You're hiring and need multiple @yourdomain.com accounts
You want native Google Calendar invites from your branded address
You need shared drives or team collaboration features
You want a cleaner separation between personal and business email

Don't pay for Google Workspace on day one. The free setup is professional enough to close deals, send investor updates, and handle customer support.

Other 80/20 Email Recommendations

Create 3-4 aliases for free: hello@, support@, billing@, founder@ — all forwarding to the same Gmail. This looks professional and helps you filter/label incoming mail.
Set up Gmail filters to auto-label emails by which alias received them (e.g., label "Support" for anything to support@).
Add a professional email signature with your name, title, product name, and website link. Keep it minimal — no logos, no quotes, no social icons.
Use "Canned Responses" (Gmail Templates) for repetitive replies: support answers, sales follow-ups, investor FAQs.
Never send marketing emails from your primary domain — use a subdomain like mail.yourdomain.com to protect your main domain's reputation. Your lifecycle email tool handles this separately.

Part 2: Lifecycle Email Marketing

Once you have professional email set up, here's how to build the automated sequences that drive activation, retention, and revenue.

Workflow

Email Sequence Setup:
- [ ] Choose which sequence you need (welcome, trial expiry, re-engagement, etc.)
- [ ] Write each email (subject, preview text, body, CTA)
- [ ] Define triggers and timing
- [ ] Set up in your email tool
- [ ] Test: send to yourself on mobile
- [ ] Track opens, clicks, and conversions

Choosing an Email Tool

Stage	Tool	Why	Cost
Pre-revenue	Resend or Loops	Modern, developer-friendly, good free tier	Free tier
0-$5K MRR	Customer.io or Loops	Behavioral triggers, event-based sequences	$0-150/mo
$5K+ MRR	Customer.io or Intercom	Advanced segmentation, in-app + email	$150+/mo

For most bootstrapped founders: Loops (simple, modern) or Resend (if you want to code your own templates). Graduate to Customer.io when you need complex behavioral triggers.

Welcome Sequence (Most Important)

Triggered on signup. Goal: get users to their aha moment.

Tell AI:

Write a 5-email welcome sequence for our SaaS:
- Product: [what it does]
- Aha moment: [the first action where users experience value]
- Signup flow: [what happens after signup — onboarding wizard, empty dashboard, etc.]

Email 1 (send immediately): Welcome + single CTA to start [aha action]. No fluff.
  Subject line under 50 chars. Body under 100 words.

Email 2 (Day 1, if user hasn't activated): Quick win tip — how to get value in 2 minutes.
  Include a specific "here's how" with a link directly to the action.

Email 3 (Day 3, if user hasn't activated): Social proof — brief story of how
  someone like them got results. End with CTA to try it.

Email 4 (Day 5, if user hasn't activated): Address the #1 objection or confusion
  that prevents activation.

Email 5 (Day 7, if user hasn't activated): Personal check-in from founder.
  "Reply to this email — I read every one."

Stop the sequence as soon as the user completes [aha action].
For each email: subject line, preview text, body, CTA button text.

Trial Expiry Sequence

Triggered 3 days before trial ends. Goal: convert to paid.

Tell AI:

Write a 4-email trial expiry sequence:
- Product: [what it does]
- Trial length: [14 days / 30 days]
- What they lose on expiry: [specific features or data access]

Email 1 (Day -3): Remind what they'll lose + easy upgrade CTA.
  Mention specific features they've used during trial.

Email 2 (Day -1): Urgency + "here's everything you've built" —
  show them what's at stake.

Email 3 (Day 0): "Your trial ended." What happens next — is their data safe?
  Clear, calm, not pushy.

Email 4 (Day +3): "We saved your data." Final offer — extended trial
  or discount for annual plan.

For each: subject line, preview text, body, CTA. Keep subject lines under 50 chars.

Re-engagement Sequence

Triggered after 14+ days inactive. Goal: bring them back.

Tell AI:

Write a 3-email re-engagement sequence:
- Product: [what it does]
- Trigger: user hasn't logged in for 14+ days

Email 1 (Day 14): "Here's what's new" — 2-3 improvements since they left + CTA.
  Subject: not "We miss you" (too generic). Something specific about what changed.

Email 2 (Day 21): Value reminder — "Here's what [similar user] accomplished this week."
  Show what they're missing out on.

Email 3 (Day 30): Direct ask — "Is [Product] still useful to you?"
  If not, offer to help. If they're done, let them go gracefully.

For each: subject line, preview text, body, CTA.

Subject Line Formulas

Curiosity: "The one thing most [role]s get wrong about [topic]"
Specificity: "3 ways to [outcome] in [Product]"
Personal: "Quick question about your [project name]" (use merge tags)
Urgency (honest): "Your trial ends tomorrow"
Value: "Save 2 hours this week with [feature]"

Rules

Under 50 characters for mobile preview
No ALL CAPS. No excessive punctuation.
Personalization increases opens 20-30%
Preview text is the second subject line — don't waste it
A/B test subject lines on every send if volume allows

Transactional Emails

Receipts, password resets, invitations, notifications:

Send instantly. Users expect these within seconds.
Clear subject: "Your receipt from [Product]" or "Reset your password"
Minimal design. These are utility, not marketing.
Include a plain-text version.
Don't sneak marketing into transactional emails — legal risk and trust erosion.

Technical Setup

Before sending anything:

- [ ] SPF, DKIM, and DMARC configured (deliverability non-negotiable)
- [ ] Sending from a subdomain (e.g., mail.yourproduct.com) to protect main domain reputation
- [ ] List hygiene: remove hard bounces immediately, soft bounces after 3 fails
- [ ] Plain text fallback for every HTML email
- [ ] Mobile-responsive templates (60%+ of emails opened on mobile)
- [ ] Preference center (let users choose email types, not just unsubscribe from all)
- [ ] Track: opens, clicks, unsubscribes, spam complaints, conversions

Tell AI:

Set up email infrastructure for our app:
- Configure SPF, DKIM, and DMARC for [our domain]
- Set up a sending subdomain: mail.[domain].com
- Create mobile-responsive email templates for:
  1. Transactional (receipt, password reset, invite)
  2. Marketing (sequence emails, announcements)
- Add unsubscribe link and email preference center
- Verify deliverability with a test send

Common Mistakes

Mistake	Fix
Time-based drips only ("Day 3, Day 5")	Use behavioral triggers: "hasn't completed X"
Multiple CTAs in one email	One email, one goal, one button
"We miss you" as a subject line	Be specific: "3 new features since you left"
No plain-text version	Always include one. Some clients strip HTML.
Sending from noreply@	Use a real address. Let people reply.
No tracking	Track opens, clicks, and conversions per email
Marketing in transactional emails	Keep them separate. Trust > short-term engagement.
