# Notifications
Dollarback provides multiple ways to notify customers when they earn, redeem, or are about to lose store credit. You can use our inbuilt email system, integrate with Klaviyo or Omnisend, or automate notifications using Shopify Flows.
You can also configure a **custom expiry reminder schedule** — and this setting applies across *all* notification surfaces.
***
### ⏳ Expiry Reminder Schedule
Previously, expiry alerts were limited to fixed reminders at **1, 3, and 7 days** before credit expiration.
You can now fully customize your expiry email schedule:
* Set notifications at any number of days before expiry
* Add up to 5 reminder notifications
* Align alerts precisely with your store credit validity rules
Once configured, this schedule applies globally across:
* Inbuilt Email
* Klaviyo
* Omnisend
* Shopify Flows
This ensures consistent timing and customer experience across every channel.

### ✉️ Inbuilt Email
