Upsell Email Prompt

What it does

Writes an upsell or upgrade email triggered by a specific customer signal — hitting a usage limit, showing behavior that suggests they need a higher tier, or reaching a natural transition point. The output is specific to the trigger and frames the upgrade around the customer's outcome, not your revenue. It doesn't sound like a marketing email; it sounds like a relevant, timely recommendation.

How to use it

The trigger field is the key input. Before using this prompt, identify the behavioral signals that indicate a customer is ready to upgrade — usage ceiling, feature requests, account age, engagement patterns. Set up the email to fire on those signals, not on a batch schedule.

If you're not using marketing automation, use this for manual outreach to specific customers who've hit a known threshold.

Example output

Subject: You've hit your 100-export limit — here's what's next

"Hey [Name],

I noticed your team hit the 100-export limit on your current plan for the second month in a row — which tells me you're getting real use out of [Product].

The [Higher Plan] removes the export cap entirely and adds [key feature] that sounds like it would help based on how you're using the tool.

It's $[X]/month more. Given your current usage, I think it pays for itself.

Want me to switch you over? Or if you want to talk through whether it makes sense, I'm happy to jump on a 15-minute call.

[Name]"

Variations

Expansion to more seats: Add "The trigger is that the customer is sharing one account across multiple users. Write the email around team productivity and proper access."

Annual plan upgrade (from monthly): Add "The customer is on a monthly plan and has been for 8+ months. Frame the upgrade as a savings calculation — total annual cost monthly vs. annual."

Cross-sell (different product): Add "This is a cross-sell, not a tier upgrade. The customer uses [Product A] and I'm introducing [Product B]. Connect the two clearly."

High-touch / enterprise: Add "This is a large account managed by a CSM. The email should come from the CSM personally, not automated, and should suggest a conversation rather than a direct link to upgrade."

Common pitfalls

No trigger / context. "We noticed you might benefit from our Pro plan" sounds made up. If there's no real trigger, don't send the email.

Leading with price. Don't open with the cost. Open with the benefit or the trigger, then price.

CTA that requires too much friction. "Schedule a call to discuss upgrading" is high friction. "Reply and I'll set it up" or a direct upgrade link is lower friction and converts better.
