Bundle Reminders — One Email For Many Invoices
Last updated: 2026-06-03
When the same client has multiple unpaid invoices that all hit a reminder on the same day, Duefy automatically combines them into one email instead of sending several.
Why this matters
If a client owes you 5 invoices, sending 5 separate emails in one day is:
- Annoying for the client (they may unsubscribe or mark as spam)
- Bad for your sender reputation
- Less likely to get paid — decision overload kills action
A single email listing all 5 invoices with a per-invoice Pay button gets you:
- Higher open rate (one email, not a flood)
- Higher paid-by-end-of-day rate (one decision, many actions)
How the bundle email looks
Subject: Following up — 3 invoices ($4,200.00 total)
Hi Jamie, Bundling a short note about the following 3 invoices we have open — figured one note beats a stack of separate emails.
- INV-1042 — $1,500.00 — Due May 28 — [Pay]
- INV-1051 — $1,200.00 — Due May 30 — [Pay]
- INV-1063 — $1,500.00 — Due Jun 02 — [Pay]
Each Pay button is per-invoice and lands on that invoice's pay page; the client doesn't have to choose anything tricky.
Turn it off
The bundle is on by default. To switch back to one email per invoice (e.g. B2C where each invoice is a distinct purchase), go to Settings → Reminder schedule, uncheck Bundle a client's invoices into one email in the Sending behavior card, and click Save sending behavior.
What still gets a separate email
- Two invoices for two different clients on the same day — those each get their own email.
- A bundle never includes an invoice that's already paid or paused.
- A bundle never overrides the suppression list (do-not-email clients are always skipped).
