Introduction
Product bundles are more than a merchandising tactic—they’re a strategic weapon for DTC and eCommerce brands. They improve margins, raise average order value (AOV), and deepen customer loyalty—all without resorting to excessive discounting.
Yet, most brands underutilize product bundles in their email strategies due to perceived operational challenges or lack of tactical know-how.
In this guide, we’ll show you exactly how to turn product bundles into a revenue engine using intentional, targeted, and scalable email marketing.
Why Promote Product Bundles Through Email?

Email is one of the most conversion-driven channels in the eCommerce toolkit. When combined with bundles, the result is higher AOV and stronger margins.
Benefits of Promoting Bundles via Email:
Benefit | Impact |
---|---|
Increased AOV | Customers spend more per order |
Improved LTV | Bundled buyers tend to return more frequently |
Lower CAC | Each order carries more value per acquisition |
No Heavy Discounting | Bundles add value without shrinking margins |
Easier Giftability | Curated sets make for compelling gift options |
Email Flows That Drive Bundle Revenue
1. Welcome Flow
Introduce bundles early. New subscribers often don’t know what to buy yet—bundles simplify that decision.
✅ Lead with your most popular starter kits or curated experiences.
✅ Include a visual walkthrough of what’s included.
✅ Add urgency with a “new subscriber bonus” for bundle purchases.
Suggested Image: Carousel of best-selling starter bundles with short benefit bullets.
2. Post-Purchase Flow
The perfect time to upsell or cross-sell a bundle is right after a purchase.
Scenario | Suggested Bundle Email |
---|---|
Purchased single item | “Loved that? You’ll love these together.” |
Purchased consumable | “Running low? Bundle up and save.” |
Seasonal trend | “Customers who bought this also grabbed this bundle.” |
3. Holiday & Promotional Campaigns
Bundles = built-in holiday offers.
✅ Gift bundles for BFCM, Christmas, Mother’s Day.
✅ Pre-launch with email waitlists.
✅ Add urgency through limited-time offers.
Pro Tip: Frame bundles as “Gift Sets,” “For Her,” “Stocking Stuffers,” or “Best Value Deals.”
4. Winback / Re-Engagement Flow
Bring lapsed customers back by showing them something new, valuable, and curated.
✅ Introduce new flavors, styles, or collections.
✅ Let them customize their bundle (if your platform allows).
✅ Offer exclusives only for returning customers.
Suggested Subject Line: “We’ve upgraded your favorites – come see what’s new.”
Best Practices to Promote Product Bundles via Email
1. Create High-Converting Bundle Types
Bundle Type | Purpose |
---|---|
Starter Kits | Educate and convert new users |
Best Sellers | Leverage social proof and popularity |
Mix & Match | Personalize experience and increase control |
Refill Packs | Solve for repeat buying behaviors |
Seasonal Sets | Tie into holiday campaigns |
2. Solve Logistical Challenges with Tech
Tools like Simple Bundles or Bundle Builder can:
- Track components for each bundle
- Prevent inventory mismatches
- Allow customer choice within bundles
Integration Tip: Sync with Shopify, Klaviyo, and 3PLs for seamless ops.
3. Segment for Personalization
The key to conversions: relevance.
Segment | Email Bundle Strategy |
---|---|
First-time buyers | Intro bundle with offer |
Repeat customers | Loyalty-focused bundle set |
High AOV shoppers | Premium curated bundles |
Cart abandoners | Bundle to upsell while nudging |
✅ Bonus: Collect zero-party data via quizzes to recommend bundles by skin type, taste, lifestyle, etc.
4. Educate Your Audience
Don’t assume customers understand bundles.
✅ Use infographics or GIFs to explain contents.
✅ Add bullets showing how the bundle saves money.
✅ Include testimonials or UGC from bundle buyers.
CTA Tip: Use phrases like “Shop Best-Selling Sets” or “Complete Your Routine.”
5. Use Plain Text Emails When It Matters
Heavily designed emails aren’t always best.
✅ Plain-text emails can feel personal and urgent.
✅ Use a founder or product expert persona.
✅ Add a deadline, a deal, and a direct CTA.
Example: “Last Call – Our Whiskey Bundle is Almost Gone” from Nate at Original Grain.
