You’ve crafted the perfect upsell email. Or have you? The truth is, no matter how well you think your email will perform, there’s always room to optimize. That’s where A/B testing your upsell emails becomes essential.
At Atomic Social, we help businesses increase conversions by running data-driven A/B tests that uncover what actually works. With the right testing strategy, you’ll stop guessing—and start growing your revenue faster. Here’s what to test and why it matters.
1. Subject Lines That Get the Open
If your email doesn’t get opened, nothing else matters. Subject lines are your first (and sometimes only) chance to capture attention.
What to test:
- Personalization vs. generic
- Questions vs. statements
- Urgency-driven lines vs. curiosity-based lines
Examples to test:
- “Ready to take it to the next level?” vs. “Upgrade your results—this week only”
- “Hey [First Name], don’t miss this upgrade” vs. “Unlock Pro Features Now”
Pro tip: Include preview text variations too—this snippet can influence open rates just as much as the subject line.
2. Email Layout and Design
Visual hierarchy can guide the reader’s eye—or lose their interest entirely.
What to test:
- One-column layout vs. multi-column
- Button color, size, and placement
- Including images vs. minimal design
Example:
Test an email with a full-width hero image and bold CTA button vs. a plain-text style email with an inline link.
Sometimes less is more—especially for mobile users.
3. Call-to-Action (CTA) Language
Your CTA is where the upsell actually happens. The right wording can significantly impact conversions.
What to test:
- “Upgrade Now” vs. “Get More Features”
- “Claim Your Offer” vs. “Yes, I Want the Pro Plan”
- Button vs. text link
Make sure your CTA stands out visually and communicates a benefit, not just an action.
4. Offer Type and Framing
You might be promoting the same upsell, but how you frame it can change everything.
What to test:
- Percentage discount vs. dollar-off savings
- Bonus gift vs. price discount
- Time-limited offer vs. VIP exclusive
Example:
“Upgrade today and save $20” vs. “Upgrade today and get a free bonus session—this week only”
Test different psychological triggers to see what motivates your audience.
5. Timing and Send Frequency
When and how often you send matters just as much as what you say.
What to test:
- Morning vs. afternoon send times
- Weekday vs. weekend
- 1 reminder email vs. 2 or 3 spaced-out messages
You might find that Tuesday mornings yield the highest conversion—or that a second email 48 hours later seals the deal.
6. Personalization Elements
Personalization can lift open and click rates—but it has to be relevant.
What to test:
- First name in the subject line
- Mention of previous purchase or behavior
- Custom product/service recommendations
Example:
“Hi Sarah, your next best step is our Advanced Facial Package” vs. “Want better results? Try our top-tier service”
Relevant personalization often outperforms general promotions.
7. Testimonials and Social Proof
Adding customer success stories or star ratings can build trust—but they need to be placed strategically.
What to test:
- Including a testimonial vs. no testimonial
- Placing it above vs. below the CTA
- Featuring one detailed quote vs. multiple quick blurbs
Social proof might be the extra push someone needs to say yes to your upsell.
