Birthday mailer — automatic, personal, effective
Birthday messages are sent automatically 7 days before the birthday — with a personalised voucher, restaurant branding and a redemption rate of 55–65%. No manual effort, no forgetting, no generic one-size-fits-all.
7-day window: timing makes the difference
Why 7 days before the birthday rather than on the day itself? On their birthday, people have plans — dinner with family, friends invited over. A message arriving 7 days before gives time to plan a visit: 'I could go out to celebrate my birthday — here's a voucher.' Guests who come on their birthday often bring others — raising the total ticket per table. The 7-day window is configurable: 3, 5, 7 or 14 days.
Personalised voucher in the birthday mailing
The birthday message automatically contains a personalised voucher: either a percentage discount (e.g. 15% off the next order), a fixed amount (e.g. €5), a free product from a defined list (e.g. free dessert) or free delivery. You configure the voucher type once. Each birthday voucher is unique and redeemable only once — no sharing.
Branding template: your logo, your voice
The birthday mailer is a fully branded template. You add your logo, primary colour and a personal greeting: e.g. 'Happy birthday, [first name]! We're delighted to celebrate your special day with you.' The rest of the template is generated automatically by the system — product image, voucher code, CTA button 'Order now.' No HTML knowledge required.
Measurement: redemption rate and revenue per mailing
KundenSystem measures for every send: email open rate, click rate on the CTA, voucher redemption rate and average order value on redemption. Typical benchmarks: open rate 60–70% (because birthday messages feel personal), redemption rate 50–65%. You see these figures in the marketing dashboard — and can adjust voucher value or timing if the redemption rate is below expectation.
Collecting birthday data in a GDPR-compliant way
Birthday data is requested when creating the customer account — with a clear explanation: 'So we can send you something special on your birthday.' Providing it is voluntary. Customers without a birthday on file receive no birthday mailer and are not automatically chased. Deletion of the birthday date on request is possible with one click.

Common questions about the birthday mailer
What happens if a guest hasn't provided their birthday?
Nothing. The system does not send birthday emails to guests without a birthday on file. You can optionally set up a one-time request: 'Share your birthday to receive a birthday voucher' — but only if the guest has active marketing opt-in.
Can I change the voucher in the birthday mailing at any time?
Yes. You change the voucher configuration in KundenSystem, and all future birthday emails will contain the new voucher. Already-sent emails with old vouchers remain valid until their configured expiry date.
How long is the birthday voucher valid?
Configurable. Default: 30 days from send date. This gives guests enough time to redeem after their birthday. You can also set a fixed expiry date or configure 'no expiry'.
