Some churn is unavoidable, but a good share of it is preventable: cards expire, users drift away before they see value, trials end without a nudge. You don't need a complex system to catch these moments, just the right message at the right time.

This guide provides 9 copy-and-paste email templates designed to tackle the most common causes of churn: failed payments, user inactivity, and poor onboarding. Set them up as automated emails in your email service provider or billing tool.

Part 1: Dunning Emails (to recover failed payments)

Involuntary churn from failed payments is the easiest churn to fix: the customer didn't decide to leave. Turn on your payment processor's automatic retries (Stripe calls them Smart Retries), then add a simple, helpful email sequence on top.

Template 1: The First Gentle Nudge (Payment Failed)

Subject: Heads up - there was an issue with your payment

Hi {{first_name}},

I wanted to give you a quick heads-up that the recent payment for your {{product_name}} subscription failed.

This can happen for a number of reasons, like an expired card. You can update your payment information here to keep your account active:

No worries for now—your account is still fully functional. If you have any questions, just reply to this email.

Template 2: The "Card Expiring Soon" Reminder

Subject: Your card on file for {{product_name}} is expiring soon

Hi {{first_name}},

Just a friendly reminder that the card we have on file for your {{product_name}} account is set to expire at the end of this month.

To ensure uninterrupted service, you can update your payment details here:

Taking a moment to do this now will prevent any issues with your next renewal.

Thanks,

Template 3: The Final Warning (Subscription Paused)

Subject: [Action Required] Your {{product_name}} account is now paused

Hi {{first_name}},

We've tried to process the payment for your {{product_name}} subscription a few times without success.

To prevent accidental cancellation, your account has been paused, but all your data is safe. To reactivate your subscription and get back to work, please update your billing information here:

[Link to Billing Page]

If we don't hear from you in the next 7 days, your account will be fully canceled.

If you need any help, please let me know.

Thanks,

{{founder_name}}

Part 2: Proactive Engagement Emails (to prevent inactivity churn)

Active users are far less likely to churn. These emails are designed to re-engage users who haven't logged in recently.

Template 4: The "Haven't Seen You in a While" Nudge

Subject: Thinking of you, {{first_name}}

Hi {{first_name}},

It's been a little while since you last logged into {{product_name}}. We're constantly shipping new features and improvements, and we'd love for you to see what's new.

Is there anything we can do to help you get more value out of the product? We're always here to help.

Template 5: The "Did You Know?" Feature Highlight

Subject: A little-known feature you might love

Hi {{first_name}},

Template 6: The Personal Check-in from the Founder

Subject: How are things going with {{product_name}}?

Hi {{first_name}},

I'm {{founder_name}}, the founder of {{product_name}}. I was just looking at your account and noticed you haven't been very active lately.

I'm not writing to sell you anything—I just wanted to personally ask if the product is meeting your expectations. Are you running into any trouble or finding that it doesn't solve the problem you hoped it would?

Your honest feedback would be incredibly valuable.

Thanks for giving us a try,

Part 3: Trial Conversion & Cancellation Aversion Emails

These emails are for critical moments at the end of a trial or when a user indicates they want to cancel.

Template 7: The "Trial Expiring Soon" Email

Subject: Your {{product_name}} trial ends in 3 days

Hi {{first_name}},

Just a heads-up that your free trial for {{product_name}} is ending in 3 days. I hope you've had a chance to see how it can help you [achieve core value proposition].

Best Practices for Implementation

  • Personalize: Always use the customer's first name.

  • Send from a Real Person: Use your own name (e.g., [email protected]) instead of a generic no-reply address. This encourages replies.

  • Be Helpful, Not Demanding: Your tone should be one of a helpful partner, not a bill collector.

  • Use Direct Links: Always link directly to the page where the user can perform the desired action (e.g., the billing page, not the dashboard).

  • Measure It: Track how many failed payments get recovered and how many inactive users come back after each email, and adjust the timing and copy.
