Why Email Flows Are the Backbone of Profitable Email Marketing
In the world of eCommerce, email marketing remains one of the most cost-effective and high-ROI strategies for driving revenue and building customer loyalty. But here’s the part many brands overlook: it’s not just about sending weekly newsletters or running sales campaigns.
If you’re not using automated email flows (also called email sequences or automations), you're leaving revenue, retention, and customer engagement on the table.
At Milhook, we help brands unlock the full potential of email marketing by building powerful, data-driven flows that engage customers at every step of their journey.
What Are Email Flows (And Why Should You Care)?
Email flows are a series of pre-written, behavior-triggered emails that automatically send when a customer takes (or doesn’t take) a specific action—like subscribing to your list, adding a product to their cart, or going inactive.
Unlike manual campaigns, these emails are sent at exactly the right time, based on what your customer is doing. Once they’re set up, they run on autopilot, working behind the scenes 24/7 to drive conversions and build loyalty.
Why email flows matter:
They boost sales with no ongoing effort
They create a personalized experience for your subscribers
They recover lost revenue from cart abandonments
They nurture new leads into loyal customers
They increase customer lifetime value (LTV) over time
The 5 Core Email Flows Every eCommerce Brand Needs
1. Welcome Flow
The welcome series is your brand’s first impression. It’s your opportunity to introduce your story, values, and products—and turn new subscribers into first-time buyers.
What to include:
A warm introduction and brand story
Your lead magnet or discount code
Social proof (reviews, press, user-generated content)
A clear call to shop
Brands that include a discount in their welcome flow often see significantly higher conversion rates.
2. Browse Abandonment Flow
If a subscriber browses your site but doesn’t add anything to their cart, you can trigger a reminder based on that interest.
Why it works: They’ve shown intent—you just need to re-engage them.
What to include:
A recap of products viewed
Trust-building content (shipping info, guarantees)
Time-sensitive offers or follow-up education
3. Abandoned Cart Flow
Cart abandonment emails are one of the most powerful automations in eCommerce, often recovering 10–20% of otherwise lost sales.
What to include:
Reminder of the cart contents
Urgency or limited-time incentive
Customer testimonials or satisfaction guarantees
A direct call to action to complete the purchase
For best results, space out two to three emails over 24 to 48 hours.
4. Post-Purchase Flow
The customer journey doesn’t stop at the sale. A well-designed post-purchase flow builds trust, reduces returns, and drives repeat orders.
What to include:
Order confirmation and a sincere thank you
Delivery expectations and product tips
Request for a review or referral
Cross-sell or upsell opportunities once the product arrives
5. Re-Engagement Flow
Every email list has inactive subscribers. A re-engagement sequence gives them a chance to reconnect—or lets you clean your list of unresponsive contacts.
What to include:
Acknowledge inactivity in a friendly way
Offer a compelling reason to come back
Give options to update preferences
A final message if they don’t respond
The ROI of Automated Email Flows
Here’s the bottom line: brands with strategic email flows generate more revenue with less manual effort. According to Klaviyo, automated emails account for 30 to 50 percent of total email revenue for high-performing eCommerce brands.
At Milhook, we’ve helped brands increase their email revenue from $8,000 to over $23,000 per month in under 60 days—just by optimizing these five core flows.
