Aampe allows you to use the same component more than once within a single message—for example, a Greeting in both the Header and Body, or a Value Proposition used in both the subject line and title of an email. While this is not recommended and should only be done with intention, we can ensure the message remains consistent by keeping the labels synced across repeated components. This is done using a feature known as Label Sync. Label Sync is an optional feature that ensures repeated components stay aligned in how they use labels and alternates.
Note: When you repeat components in a message, labels are always synced by default.

​
Why Label Sync Matters

Using the same component twice can introduce ambiguity for agents if not managed correctly. Image you have a message with two Greetings. Without syncing, an agent may send a message in which:
  • Greeting 1 uses label Friendly
  • Greeting 2 uses label Professional The agent would then struggle to understand whether the Greeting Label Casual or Professional drove user behavior
Label Sync prevents this by turning labels into coherent tracks — Casualalternates always appear together; Professional alternates always appear together.

​
When should I Sync Labels?

Here are some examples of when syncing labels makes sense:
  • When using the same discount throughout the message — e.g., when “10% off” appears in two places (subject line + body) and must always match.
  • When you’re talking about the same Offering — e.g., if your email is about “Hotels” you don’t want to mention “Flights” out of the blue
  • To keep Tone consistent — e.g., you don’t want to sound Casual in the header but Professional in the body

Why am I seeing this error?

When you add the same component twice in a message, you may end up seeing an error like this (below) in your editor. Don’t panic — here’s why it happened, and how you can fix it. Lockerror Pn When components are repeated in the same message, by default they are synced in the UI. This means the system is expecting both components to share the same set of labels. When this doesn’t happen, you see this error.

​
How you can fix this

  1. Turn off label sync
    Click on the lock icon on the bottom right. This will mean agents are now free to mix and match all alternates within both components, across all labels. The components may or may not share the same labels.
  2. Ensure both components have the same labels
    If you want to keep label sync on and remove the error, make sure both components are using the same set of labels. For example:

    Greeting 1 has labels Friendly and Professional
    Greeting 2 has labels Quirky and Professional

    You can either 👉
    (A) Remove Friendly and Quirky from both Greetings
    (B) Add Friendly to Greeting 2 and add Quirky to Greeting 1
    (C) Replace Quirky in Greeting 2 with Friendly
