Email Marketing and Customer Retention for LED Therapy Brands

The Email Foundation

Building the List

The list-building strategy:

Opt-in incentives:

• First-purchase discount (10-15% off first order)
• Free guide (“The Complete LED Therapy Handbook”)
• Early access to new products
• Exclusive subscriber-only offers

Where we capture emails:

• Website popup (exit intent and 30% scroll)
• Product pages
• Checkout (most effective — highest purchase intent)
• Instagram bio link
• Amazon brand store (redirect to email capture)

The quality principle:
A list of 1,000 highly engaged subscribers is worth more than 10,000 disengaged ones. We focus on quality over quantity.

List Segmentation

Segment your list from the start. We use:

By purchase status:

• Non-customers (subscribers who haven’t purchased)
• Customers (purchased at least once)

By purchase behavior:

• First-time buyers
• Repeat buyers
• High-value customers ($200+ lifetime value)

By engagement:

• Active (opened email in last 90 days)
• Lapsed (purchased but no engagement in 90+ days)
• Dormant (never purchased, no engagement in 6+ months)

By interests:

• Based on products purchased or browsed
• Based on email engagement patterns

The Email Sequence Architecture

The Post-Purchase Sequence

The most important email sequence is what happens after someone buys. This is where retention is built.

Day 0 (Order confirmation):

• Order confirmation
• What to expect (shipping timeline)
• Customer support contact
• Excitement building

Day 1 (Shipping notification):

• Tracking information
• Estimated delivery
• “Your product is on the way”

Day 3 (Delivery follow-up):

• Confirm product arrived
• Ask if they have any questions
• Set expectations for usage (build habit)

Day 7 (First week check-in):

• How are they finding the product?
• Tips for getting started
• Link to usage guide
• Link to how-to content

Day 21 (Results check):

• Early results feedback
• Address common early concerns
• Usage reminder
• Request honest review (subtle)

Day 45 (Mid-month engagement):

• Related content (how others use the product)
• Usage inspiration
• Link to community/social

Day 60 (Loyalty touchpoint):

• Thank you for being a customer
• Ask for product feedback
• Invite to review
• Early preview of new products

The Welcome Sequence for Non-Customers

Subscribers who haven’t purchased need nurturing:

Email 1 (Welcome):

• Thank them for joining
• Who you are and what you do
• What to expect from emails
• First value offer (discount or content)

Email 2 (3-5 days later):

• Brand story
• Product education
• Why customers love the product

Email 3 (7-10 days later):

• Featured product
• Social proof
• Call to action

Email 4 (14-21 days later):

• Second chance offer
• Urgency if appropriate
• Why this product is right for them

Email 5 (30 days later):

• Engagement email (question, poll)
• Re-engagement for those who haven’t opened
• Clean up inactive subscribers

The Re-Engagement Sequence

For lapsed customers (purchased but haven’t engaged in 90+ days):

Email 1 (We miss you):

• “It’s been a while”
• What you’ve been up to
• New products or improvements
• Exclusive offer to come back

Email 2 (7-10 days later):

• “We noticed you haven’t been around”
• Customer story/testimonial
• Why customers keep coming back
• Specific offer to return

Email 3 (7-10 days later):

• Final attempt
• “We’d love to have you back”
• Last-chance offer
• Link to unsubscribe (let people leave gracefully)

Post sequence:

• If still inactive, suppress from regular sends
• Only re-engage with major announcements or best offers

The Content Strategy

Email Content Types That Work

Transactional content:

Promotional content:

Content That Doesn’t Work

• Generic “just checking in” emails
• Salesy content without value
• Content that doesn’t match subscriber interests
• Too many promotional emails (burns out subscribers)

The Metrics That Matter

Key Email Metrics to Track

List health metrics:

• List growth rate (target: 10%+ monthly)
• List churn rate (target: <2% monthly)
• Engagement rate (open rate, click rate)

Our benchmarks:

• Average open rate: 28%
• Average click rate: 3.5%
• Unsubscribe rate: <0.3%

Revenue metrics:

• Revenue per email sent
• Revenue per subscriber annually
• Campaign-attributed revenue
• Lifecycle value of email-generated customers

Deliverability metrics:

• Bounce rate (target: <2%)
• Spam complaint rate (target: <0.1%)
• List growth vs. list decay

The Revenue Calculation

Revenue per email sent:

• Take total email-attributed revenue
• Divide by number of emails sent
• Our average: $0.15-0.25 per email sent

Lifetime value of email list:

• Total revenue from email / total subscribers = $12.14/year
• This doesn’t include untracked brand-building value

The Automation System

The Automated Flows (Always-On)

These emails send automatically based on triggers:

• Welcome series (trigger: subscribe)
• Abandoned cart (trigger: add to cart, no purchase)
• Browse abandonment (trigger: view product, no cart)
• Post-purchase series (trigger: purchase)
• Win-back sequence (trigger: 90+ days inactive)
• Review request (trigger: 14 days post-delivery)
• Replenishment reminder (trigger: estimated product lifecycle)

Abandoned Cart Optimization

Abandoned cart emails are the highest-ROI email automation. Our results:

Our sequence:

• Email 1 (1 hour after abandonment): “You left something behind”
• Email 2 (24 hours later): Reminder + urgency
• Email 3 (48 hours later): Last chance + incentive

What we include:

• Product photo
• Product name and price
• Easy return to cart
• Trust signals
• No excessive pressure

Our results: 12% of cart abandoners complete purchase through email sequence.

The List Hygiene Process

Regular Maintenance

Monthly:

• Remove hard bounces immediately
• Suppress inactive subscribers from regular sends
• Clean up syntax errors in email addresses

Quarterly:

• Deep engagement analysis
• Large engagement campaign to re-engage or clean
• Suppress dormant subscribers

The cleaning threshold:

• If subscriber hasn’t opened in 6 months and hasn’t purchased: suppress from regular sends
• If subscriber hasn’t opened in 12 months: remove from list entirely
• Exception: VIP customers, regardless of engagement

Suppression Management

Always suppress:

• Unsubscribes (always, per CAN-SPAM and GDPR)
• Hard bounces (immediate)
• Customers who complained

Why it matters:

• Better deliverability
• More accurate engagement metrics
• Better sender reputation

The Honest Assessment

Email marketing works. The brands that succeed in DTC understand that their email list is their most owned, most controllable channel.

What we did right:

• Built the list from day one
• Focused on engaged subscribers over raw list size
• Automated the critical sequences (post-purchase, abandoned cart)
• Tested relentlessly (we tested 40+ subject lines last year)
• Cleaned the list regularly

What we wish we’d done sooner:

• Started the post-purchase sequence earlier
• Built the abandoned cart sequence before we did
• Segment by engagement level earlier
• Invested in email design and copywriting sooner

The brands that build strong email programs treat their list as an asset, not an afterthought. Every subscriber is a potential customer for life, not just for the first transaction.

Build the list. Serve them well. Ask for the sale at the right moments. The returns compound over time.
