# How Do I Create My Post-Purchase Messaging?

Once your Impact Wallet is activated, you can start designing your email templates. These can be found under ‘Notification Templates’ in your Engagement Hub. 

|| You can now [sync your customers' impact data](/en/article/sync-data-with-klaviyo-6ka0ag/) directly with Klaviyo to send out your own emails and dynamically add impact data to them.

* You can pick the type of email you are designing. This could be:

**Invitation:** Sent when a customer has not yet claimed their account and completes an impact action such as placing an order.

**Update:** Sent when a customer has claimed their account and completes an impact action such as leaving a review.

**Nudge:** Nudges are sent out on the 3rd, 7th and 14th day after the customer’s first impact action took place.

* You can then go on to edit the email including the domain, text & imagery used throughout the notification.

We also provide dynamic variables to customise your email.
