Step 2: Create an automation in Omnisend for reorder reminders

1: Create Automation

• In Omnisend, go to Automation in the left menu.
• Click on + Create workflow in the top right corner and then click Create from scratch in the top right corner.

2: Choose Trigger

• From the right panel, there is a trigger dropdown. Select reorder_reminder (api) under API section in the dropdown. Cross check that the trigger type is set to reorder_reminder (api).

3: Add Email Action

• In the automation editor, drag and drop email from the left panel.

4: Configure Email Settings

• Click on the email action to open settings.
• On the right hand side, set Sender name and Sender email for your brand.
• Edit the Subject line and Preheader text for reorder reminders.

5: Edit Email Content

• Click on Edit content to open the email editor. Make sure to save the settings first.
• Use the drag-and-drop editor to customize your email.
• To show order items, drag and drop the block from dynamic content in the left panel. Select the last one as it allows you to display order items vertically.

The items variable contains the order items. Use these dynamic variables in your email:

Variable	Description
[[ item.title ]]	Product title
[[ item.quantity ]]	Quantity ordered
[[ item.price ]]	Product price
[[ item.image ]]	Product image URL

6: Add Personalization and Conditional Content

Omnisend uses special syntax for dynamic content. Here are key variables you can use:

Personalization Variables:

Variable	Description
[[ event.customer_name ]]	Customer’s name
[[ event.discount_text ]]	Discount text

Conditional Syntax Example:

[% if event.customer_name %]
  Hi [[ event.customer_name ]]!
[% endif %]

[% if event.discount_text %]
  [[ event.discount_text ]]
[% endif %]

This shows content only when the variable has a value.

7: Add Action Buttons

• In the left panel, drag and drop two buttons block. Click on the button to edit text and link.
• First button is for reorder link and second button is to view order details.

Note

If you are using usage-based reminders or AI-based reminders, the second button (View Order) is irrelevant. The View Order button is only required for customer-defined reminders.

8: Activate the Automation

• Click on Finish editing on the top right.
• On the automation screen, edit the name of automation by clicking on edit on top left.
• Click on Start workflow to start the automation.
