If guests are not receiving emails from a birthday or voucher automation, there are a few common causes to check. The most likely reason is that the voucher offer attached to the automation has run out of available codes.

How voucher automations work

A birthday voucher automation typically runs once a day. Each day, the automation checks for contacts whose birthday is a set number of days away and sends each of them a unique voucher code from the offer linked to the automation. The voucher code is merged directly into the email.

What happens when voucher codes run out

Each time the automation runs, it checks whether there are enough remaining voucher codes in the linked offer to cover that day's send. If there are not enough codes remaining, no emails are sent for that day's run.

This means that if your voucher offer runs out of codes mid-way through the month, guests with upcoming birthdays will not receive their email — with no visible error shown to you.

Note: Account admins receive an email notification when an offer has used 80% and 100% of its voucher codes. If you are receiving these notifications, top up your offer codes before the automation stops sending.

How to check and fix this

1. Go to the Vouchers section and open the offer linked to your birthday automation.
2. Check how many codes remain. If the offer is at or near 100% used, this is the cause.
3. Add more codes to the offer or create a new offer with additional codes.
4. Check the automation is still linked to an active offer with remaining codes.

Other reasons the automation may not be sending

If the voucher offer has codes remaining and the automation is still not sending, check the following:

• Date of birth data is missing or incorrect. If contacts do not have a date of birth recorded, the automation cannot identify them as birthday recipients. Check a few contact profiles to confirm DOB data is present and correctly formatted.
• The automation is paused or inactive. Confirm the automation is active in your Automations section.
• The contact is unsubscribed. The automation will not send to contacts who are unsubscribed from email marketing.
