Usage-Based Expansion Templates
Template 1: Approaching Plan Limits
When to use: Customer is at 80%+ of their plan limit
Subject: Quick heads up about your {{product}} usage
Hi `{{firstName}}`,
I noticed your team is approaching your plan limit—you've used `{{usagePercent}}`% of your monthly `{{limitType}}` this month.
At your current pace, you'll likely hit the limit around `{{projectedDate}}`.
A few options:
1. **Upgrade to `{{nextPlan}}`** - Get `{{limitIncrease}}` more `{{limitType}}` plus `{{additionalBenefit}}`
2. **Add a usage pack** - One-time `{{packAmount}}` `{{limitType}}` for $`{{packPrice}}`
3. **Optimize usage** - I can share some tips on getting more from your current plan
What works best for you?
`{{signature}}`
P.S. Upgrading now would also unlock `{{bonusFeature}}`, which I've seen help similar teams `{{specificBenefit}}`.Template 2: Consistent Overage Charges
When to use: Customer has paid overages 2+ months in a row
Subject: Save money on your {{product}} bill
Hi `{{firstName}}`,
Looking at your account, I noticed you've had overage charges the past `{{overageMonths}}` months—totaling $`{{overageTotal}}`.
Here's the thing: upgrading to `{{nextPlan}}` would actually save you money.
**Current situation:**
- Base plan: $`{{currentPrice}}`/mo
- Average overages: $`{{averageOverage}}`/mo
- Total: $`{{currentTotal}}`/mo
**With `{{nextPlan}}`:**
- Price: $`{{upgradedPrice}}`/mo
- Overages: $0
- Plus: `{{additionalBenefits}}`
That's $`{{monthlySavings}}` less per month, plus no more surprise charges.
Want me to switch you over? Takes about 2 minutes.
`{{signature}}`Template 3: Power User Identification
When to use: Individual user is significantly outpacing plan features
Subject: {{firstName}}, you're a power user 🚀
Hi `{{firstName}}`,
Your usage data caught my eye—you've `{{specificAction}}` `{{usageCount}}` times this month, which puts you in the top `{{percentile}}`% of `{{product}}` users.
You're clearly getting value from the platform, but I think you're working harder than you need to.
Our `{{premiumFeature}}` would let you `{{benefit}}`. Based on your usage, you could save roughly `{{timeSaved}}` per week.
I put together a quick 3-minute demo specifically for your use case: `{{demoLink}}`
Worth a look?
`{{signature}}`Growth Trigger Templates
Template 4: Team Expansion Detected
When to use: Customer has added new team members recently
Subject: Congrats on the team growth!
Hi `{{firstName}}`,
I noticed you've added `{{newMemberCount}}` team members to `{{product}}` recently—congrats on the growth!
Quick thought: your current plan includes `{{currentSeats}}` seats, and you're now at `{{totalSeats}}`.
Our `{{teamPlan}}` is designed for growing teams like yours:
- `{{teamBenefit1}}`
- `{{teamBenefit2}}`
- `{{teamBenefit3}}`
Plus, at your team size, the per-seat cost actually drops from $`{{currentPerSeat}}` to $`{{discountedPerSeat}}`.
Want to hop on a quick call to discuss what makes sense as you scale?
`{{signature}}`Template 5: Department Expansion Opportunity
When to use: Usage suggests multiple departments could benefit
Subject: Expanding {{product}} across {{companyName}}?
Hi `{{firstName}}`,
I've been looking at how your team uses `{{product}}`, and I noticed something interesting: `{{usagePattern}}`.
This often indicates that other teams at `{{companyName}}` could benefit too. We've seen companies like `{{similarCompany}}` roll out `{{product}}` to their `{{relevantDepartment}}` team with great results.
If you're interested, I can:
1. Set up a demo for other stakeholders
2. Share a business case template
3. Connect you with `{{similarCompany}}`'s admin to hear their experience
Would any of these be helpful?
`{{signature}}`Template 6: Usage Pattern Suggests Upgrade
When to use: Usage patterns match higher-tier use cases
Subject: Are you ready for {{featureName}}?
Hi `{{firstName}}`,
Based on how you're using `{{product}}`, I think you might be ready for our `{{advancedFeature}}`.
Here's why: You've been `{{specificBehavior}}`, which is exactly what our `{{tierName}}` customers do before they upgrade. Once they have access to `{{advancedFeature}}`, they typically see `{{improvement}}`.
For example, `{{customerExample}}` was in a similar situation. After upgrading, they `{{successStory}}`.
Would a 15-minute walkthrough of `{{advancedFeature}}` be useful?
`{{signature}}`Feature-Based Templates
Template 7: New Feature Announcement
When to use: New feature released that matches customer's use case
Subject: New: {{featureName}} is live
Hi `{{firstName}}`,
We just launched `{{featureName}}`, and based on your usage, I immediately thought of you.
Here's what it does: `{{featureDescription}}`
For teams like yours that `{{relevantBehavior}}`, this typically means:
- `{{benefit1}}`
- `{{benefit2}}`
- `{{benefit3}}`
`{{featureName}}` is available on our `{{requiredPlan}}` plan. Given how you're using `{{product}}` today, I think it could `{{specificValue}}`.
Want to try it out? I can set up a trial or walk you through it.
`{{signature}}`Template 8: Feature Adoption Follow-Up
When to use: Customer started using a feature, could use premium version
Subject: Getting more from {{featureName}}
Hi `{{firstName}}`,
I saw you started using `{{featureName}}` last week—nice! Early feedback?
Since you're already seeing value there, I wanted to mention `{{premiumVersion}}`. It includes:
- `{{premiumFeature1}}`
- `{{premiumFeature2}}`
- `{{premiumFeature3}}`
Teams that use `{{featureName}}` heavily (like yours) typically get `{{multiplier}}`x more value with the premium version.
I can set up a trial if you'd like to test it with your actual workflow.
`{{signature}}`Template 9: Integration Opportunity
When to use: Customer could benefit from connecting additional tools
Subject: Connect {{product}} to {{theirTool}}?
Hi `{{firstName}}`,
I noticed `{{companyName}}` uses `{{theirTool}}`—have you considered connecting it to `{{product}}`?
Our `{{integrationName}}` integration syncs `{{syncDetails}}`, which eliminates `{{painPoint}}` and typically saves `{{timeSaved}}`.
Setup takes about `{{setupTime}}`, and I'm happy to walk you through it.
The integration is available on `{{requiredPlan}}`. Let me know if you'd like to see how it works.
`{{signature}}`Renewal Trigger Templates
Template 10: Pre-Renewal Value Summary
When to use: 60-90 days before renewal
Subject: Your {{product}} year in review
Hi `{{firstName}}`,
Your renewal is coming up on `{{renewalDate}}`, so I put together a quick summary of your `{{product}}` impact this year:
**Your Results:**
- `{{metric1}}`: `{{value1}}`
- `{{metric2}}`: `{{value2}}`
- `{{metric3}}`: `{{value3}}`
**Compared to when you started:**
- `{{improvement1}}`
- `{{improvement2}}`
For next year, I'd recommend considering `{{upgradeSuggestion}}` based on `{{reason}}`. This would add `{{additionalValue}}`.
Want to schedule a call to review your renewal options? I have some ideas for getting even more value.
`{{signature}}`Template 11: Annual Upgrade Incentive
When to use: Monthly customer approaching renewal
Subject: Lock in {{discountPercent}}% off for the year
Hi `{{firstName}}`,
Your monthly subscription renews on `{{renewalDate}}`. Before that happens, I wanted to offer you something:
Switch to annual billing and save `{{discountPercent}}`%—that's $`{{annualSavings}}` back in your pocket.
**Monthly**: $`{{monthlyPrice}}`/mo = $`{{yearlyTotalMonthly}}`/year
**Annual**: $`{{annualPrice}}`/year (save $`{{annualSavings}}`)
Plus, annual customers get `{{annualPerk}}`.
Want me to make the switch? Takes two clicks.
`{{signature}}`Template 12: Renewal with Upgrade Bundle
When to use: Renewal time with clear expansion opportunity
Subject: Special renewal offer for {{companyName}}
Hi `{{firstName}}`,
Your renewal is coming up, and I wanted to share a special offer I put together for `{{companyName}}`:
**Standard Renewal:**

- Everything you have today
**Growth Bundle (`{{discountPercent}}`% off):**
- `{{upgradedPlan}}`: $`{{bundlePrice}}`/year (normally $`{{normalPrice}}`)
- Includes: `{{includedFeature1}}`, `{{includedFeature2}}`, `{{includedFeature3}}`
- Savings: $`{{savings}}`
Based on your usage this year, the Growth Bundle would give you `{{specificBenefit}}`.
This offer is valid until `{{expirationDate}}`. Let me know if you'd like to discuss.
`{{signature}}`Milestone Trigger Templates
Template 13: Usage Milestone Celebration
When to use: Customer hits a significant usage milestone
Subject: 🎉 {{companyName}} just hit {{milestone}}!
Hi `{{firstName}}`,
Just wanted to share some good news: `{{companyName}}` just `{{milestoneAchievement}}`!
That puts you in the top `{{percentile}}`% of `{{product}}` users. Clearly, the platform is working for you.
Given how much you've grown, you might be interested in `{{relevantUpgrade}}`. It would let you `{{benefit}}` and is typically the next step for teams at your stage.
Want to learn more, or just keep crushing it on your current plan? Either way, congrats!
`{{signature}}`Template 14: Success Story Request + Upgrade
When to use: Customer has achieved notable results
Subject: Would you share your {{product}} story?
Hi `{{firstName}}`,
I've been following `{{companyName}}`'s results with `{{product}}`, and honestly, they're impressive: `{{specificResult}}`.
Would you be open to sharing your experience in a brief case study? It would help other companies in `{{industry}}` see what's possible.
In exchange, I'd like to offer you:
- `{{incentive1}}`
- `{{incentive2}}`
- `{{incentive3}}`
Plus, I think you'd really benefit from `{{upgradeSuggestion}}` based on your results. Happy to include a trial as part of the case study partnership.

When to use: Customer's annual anniversary with your product
Subject: Happy {{years}} year anniversary, {{firstName}}!
Hi `{{firstName}}`,
Can you believe it's been `{{years}}` year(s) since `{{companyName}}` started using `{{product}}`?
Here's what you've accomplished:
- `{{accomplishment1}}`
- `{{accomplishment2}}`
- `{{accomplishment3}}`
To celebrate, I'm offering you `{{anniversaryOffer}}`—valid this month only.
Also, I've been thinking about how you could get even more value in year `{{nextYear}}`. Specifically, `{{recommendation}}` based on `{{reason}}`.
Want to hop on a call to plan out the next year?

Conclusion
Effective expansion emails are timely, personalized, and value-focused. They don't feel like sales because they're genuinely helpful—suggesting upgrades that make sense based on actual customer behavior.
Key Principles:
- Lead with value - Explain the benefit, not the feature
- Use specific data - Generic emails get ignored
- Time it right - Trigger-based beats calendar-based
- Make it easy - Clear next steps, minimal friction
- Be helpful - Even if they don't upgrade, provide value
Start with the templates that match your most common expansion triggers, customize them with your product specifics, and measure results.
Frequently Asked Questions
How many touches should an expansion sequence have?
3-5 touches over 2-3 weeks. Start with value, follow up with social proof, and end with a clear ask or deadline.
Should expansion emails come from sales or customer success?
Customer success typically gets better response rates because the relationship is established. Sales can engage for larger enterprise expansions.
What's a good response rate for expansion emails?
15-25% for well-timed, personalized expansion emails. Compare this to 1-5% for cold outreach.
