Automated email flows account for just 2 percent of total email volume but drive 37 percent of all email-generated revenue, and stores running all four core flows (welcome, abandoned cart, browse abandonment, post-purchase) see up to 320 percent more revenue per email than stores relying on newsletters alone. This is the highest-leverage, most template-able part of email marketing, and most of it only needs to be built once.
Welcome series
Triggered when someone joins your list, a welcome series averages $2.65 revenue per recipient, with the top 10 percent of merchants reaching $21.18. Welcome emails have an 83.6 percent average open rate, the highest of any flow, and outperform ordinary promotional emails by 320 percent. In 2026, the strongest welcome flows spend their first 1-2 emails on brand storytelling before introducing a discount, rather than leading with the discount immediately.
Abandoned cart recovery
Abandoned cart is the single highest-revenue flow, averaging $3.65 per recipient with the top 10 percent reaching $28.89, and 35 to 40 percent open rates with 15 to 20 percent conversion. The sequence structure matters enormously: a three-email sequence produced $24.9 million in one analyzed dataset compared to $3.8 million from a single email, a 6.5x difference.
- 1
Email 1, within 1-3 hours
A simple reminder with product images and a clear button back to checkout. No discount here: 40-50% of total recovery revenue comes from this email alone.
- 2
Email 2, around 24 hours
Reinforce value: address a likely objection, add a testimonial or product benefit the first email didn't cover.
- 3
Email 3, 48-72 hours
This is where a limited-time discount belongs, after you've already made the value case twice without one.
The other flows worth building
- Browse abandonment: triggered when someone views products but doesn't add to cart, catching intent earlier than cart abandonment does.
- Post-purchase: sets expectations (shipping, care instructions) and opens the door to a second purchase or a review request.
- Win-back: re-engages customers who've gone quiet, achieving 25-30% open rates even on a cold segment.
Note
Klaviyo and most major email platforms include pre-built templates for all of these flows. The template is the easy part; the discipline is actually reviewing and refining them with real performance data instead of setting them up once and forgetting them.
Key takeaways

- Running all four core flows together (welcome, abandoned cart, browse abandonment, post-purchase) delivers up to 320% more revenue per email than newsletters alone.
