Sending Wishlist Low Stock Emails via Omnisend

When it comes to motivating people to buy things, scarcity is one of the most powerful forces around. When shoppers add items to their wishlist, they are telling us they’re considering the product but not quite ready to buy. Our job as marketers is to nudge them across the finish line.

Leverage the Wishlist Hero integration with Omnisend to enable high-performance wishlist low stock event triggered campaigns.


  1. Wishlist Hero Gold Plus Plan or above
  2. Omnisend Email Account
  3. Wishlist Hero-Omnisend integration enabled

How To Implement

1. Enable Wishlist Low Stock Event

Before you get started, you need to make sure you’ve enabled the wishlist low stock event within Wishlist Hero Admin. To confirm, once you’ve logged in to Wishlist Hero Admin, navigate to Settings tab via the top nav. then click on configure button next to “Email reminders for on sale and Low stock wishlisted products” Make sure that it says “Low stock email reminder is enabled” and if it is disabled click the Enable Button.

Once enabled, Wishlist Hero will send an event to Omnisend each time the sale of a product drops inventory below the specified number of units. The threshold for Wishlisthero-lowstock event is set to be 10 units in the backend even though it can be customized according to requirement. Also, the low-stock event will get triggered only if the stock is reduced by an actual purchase or draft order.

There is no time delay built into the integration logic, so expect to see low stock events show up in Omnisend shortly after inventory drops below the specified unit threshold.

2. Create Omnisend Automation and Select Trigger

In Omnisend, navigate to the Automations page and select “+ New workflow”. In the upper righthand corner click the “Create custom workflow” button. In this example we’re going to call this flow “Wishlist Low Stock”.

Next you’ll need to set the trigger for this workflow. Choose “Wishlisthero-lowstock” from the dropdown on the right.

Tip: if you’re not seeing “Wishlisthero-lowstock” in your dropdown you probably haven’t had the inventory for a product drop below the threshold since enabling this event and the Omnisend integration in Wishlist Hero. Omnisend will not display flow triggers until they’ve received at least one event.

Next, we’re going to add an Audience filter, which we’ll use during development for this workflow. We’ll remove it later once we’re ready to make this workflow live. In this case we added a Tag to our test customer

Because the timing of this event isn’t driven by an action taken by the shopper, there’s no benefit to adding a time delay before the email is sent.

Next add an email to your workflow, this is will be your low stock message.

3. Create Your Email Template

The next thing we’ll do is build an email template that consumes the low stock data passed from Wishlist Hero to create our triggered email campaign.

Here are the event-level data elements included with the event:

Fill out the subject line, preheader, sender’s name and make sure you’re happy with the sender’s email address. Note that you will be able to use data elements from the Wishlisthero-lowstock event to personalize the subject and preheader text. Then click the “Edit content” button to edit the email.
