About this tool

When a subscriber's recurring card payment declines, the tone and friction of your initial notification email dictates whether you recover that customer or lose them to involuntary churn. Harsh, legalistic warnings ('Your account is suspended!') create immediate resentment, whereas overly timid emails get ignored. The gold-standard dunning email is polite, helpful, and transparent: it informs the customer of the bank decline, mentions the card's last four digits, provides a direct one-click link to update payment details without requiring password entry, and specifies the exact date of the next automated retry. Use this generator to create professional dunning email copy that recovers failed payments.

How It Works

  1. 1Input customer name, product name, card last four digits, scheduled retry date, and direct billing portal URL.
  2. 2Review the generated subject line, preheader text, and message body.
  3. 3Implement the copy in your automated Stripe or Dodo Payments dunning email templates.

Worked Practical Example

A renewal charge declines on a customer's Visa card ending in 4242.

Calculation / Steps

Inputs: Customer = 'Sam', Card = '4242', Retry = 'in 48 hours', Portal URL provided.

Expected Result

Generates clear, courteous notice explaining the bank decline and providing an immediate update link.

Frequently Asked Questions

Why should dunning emails include a direct portal link?+

Most failed payment emails are opened on mobile devices. Forcing users to remember passwords and navigate complex settings drastically lowers recovery rates.

How many dunning emails should be sent during a payment failure?+

Typically three emails across 7 to 9 days: Day 2 (polite reminder), Day 5 (urgent warning), and Day 8 (final grace period notice).

What is an acceptable payment recovery rate?+

Measure recovered revenue divided by failed revenue over a full dunning cycle. Smart retries, card updater services and clear emails with a direct update-card link tend to matter most. Compare your rate before and after each change.
