Auto Inject makes it easier to manage ad placements in your newsletters by automatically inserting promotions in predefined spots — no manual drag-and-drop required.
What Is Auto Inject?
Auto Inject is a feature that allows you to automatically place promotions in a newsletter based on a position you select during promotion template setup. Once enabled, Letterhead will handle the placement for you at the time of send, perfect for streamlining your workflow and ensuring consistent positioning.
How to Enable Auto Inject
You’ll set up Auto Inject when creating or editing a promotion template at the Organization level:
-
Go to the Promotions tab > Templates.
-
Click Create Template or edit an existing one.
-
Check the box labeled Auto Inject for newsletters.
-
Choose one of the predefined positions from the dropdown:
-
Header
-
Hero Section
-
Mid-body
-
Bottom-body
-
Footer
-
-
Save the template.
💡 You’ll still follow the usual steps to create a Campaign and Promotion using this template — Auto Inject only affects newsletter placement.
How Auto Inject Works
Once your promotion is created and scheduled:
-
You do not need to manually add a promotion block in the newsletter.
-
When the promotion date is selected in a newsletter, the promotion will automatically appear in the position selected in the template.
-
The promotion will only show if it’s scheduled to run on that newsletter’s send date.
🔒 Note: Promotions using Auto Inject are locked in place and cannot be moved within the newsletter layout. If you want more flexibility in positioning, you can leave Auto Inject unchecked and manually place promotion blocks instead.
When to Use Auto Inject
Auto Inject is a great fit if:
-
You want to maintain consistent promotion placement across all newsletters.
-
You're managing multiple advertisers and want a hands-off workflow.
-
You’ve pre-defined promotion slots that don’t change from newsletter to newsletter.
It’s especially helpful for newsletters with repeatable layouts or scheduled promotion inventory.
Can I Use Auto Inject with Manually Placed Promotions?
Yes, you can mix Auto Injected promotions with manually placed ones, but you cannot move or edit Auto Injected blocks within the newsletter builder.
If you need full control over promotion positioning in a specific newsletter, we recommend disabling Auto Inject for that template.
