PrerequisitesA model or Customer Studio parent model configured in Hightouch and at least one supported destination

What you’ll learn

  • How Match Booster enrichment works at a high level
  • Which inputs (match keys) Match Booster supports
  • Where to enable Match Booster in Hightouch
  • How to send enriched identifiers to supported destinations

Overview

Using Match Booster is a two-step process:

  1. Enrichment: Configure Match Booster to enrich your model with additional identifiers.
  2. Sync configuration: Select which enriched identifiers to send to supported destinations.

Choose where to enable Match Booster

You can enable Match Booster in two places in Hightouch. Choose the option that matches how you build and sync audiences.

OptionBest forWhere to configure
Enable on a modelSyncs built directly from a model in ActivationActivation → Models → select a model → Match Booster
Enable on a Customer Studio audience (parent model)Customer Studio audiences (built from the schema)Customer Studio → Schema → select a parent modelMatch Booster

Both setup paths enable Match Booster on the same underlying model data. The only difference is where you configure it in the UI—Match Booster enrichment works the same either way.


Step 1: Configure enrichment

In this step, you’ll:


Inputs (match keys)

Match Booster uses supported inputs (match keys) to match your records into Hightouch’s identity graph. The match keys you provide determine:

  • which records can be matched
  • what additional identifiers Match Booster can append to your model
  • what enriched identifiers you can map into your destinations

Match keys are selected in the Match Booster tab when you map a warehouse Column name to an Identifier type (such as Email, Phone, Mobile ID, or IP address depending on your use case).

Match Booster supports different match keys depending on your use case.

Known users (MB Known)

Use this option when you already have user-level identifiers like email, phone number, MAIDs, or postal address information.

Supported inputs:

Match keySupported input formatNotes
EmailPlain text, MD5, SHA256Email can be unhashed or hashed
PhonePlain textPhone must be provided as plain text
MAIDsPlain textMobile advertising IDs
Full postal addressPlain textIncludes first name, last name, street 1, street 2, city, state, postal code

Match Booster can append the following enriched identifiers to your model:

Enable Match Booster enrichment

Once you’ve confirmed your model has the right match keys, enable Match Booster enrichment.

  1. Open the model or parent model where you want to enable Match Booster:

    • Activation → Models → select a model → Match Booster

      Enable Match Booster on a model

    • Customer Studio → Schema → select a parent model → Match Booster

      Enable Match Booster in Customer Studio

  2. Toggle Enable Match Booster on.

  3. Under Which identifiers should be used to link your model to Hightouch’s identity graph?, map match keys by selecting:

    • a Column name
    • an Identifier type (for example, Email, Phone, or Mobile ID)
  4. Under Enrichment schedule, choose how often to run enrichment.

  5. Click Save.

Enrichment can take a few hours to complete, depending on the size of your model and the identifiers you selected.


Initialize Match Booster (first-time setup)

The first time you enable Match Booster for a model, you may be prompted to Initialize Match Booster.

Initialization is a one-time step that can take up to 72 hours.

If available, select Email me when enrichment is complete so you don’t need to monitor progress manually.

Initialize Match Booster pop-up


Step 2: Configure your sync

After enrichment is enabled, you can configure your sync to send enriched identifiers to supported destinations.

You can only configure Match Booster on syncs to supported destinations.


Choose what Hightouch should send to your destination

In the sync setup flow (or in an existing sync’s Configuration tab), Hightouch asks what you want to send to your destination.

This selection determines your use case, such as:

  • syncing an audience for targeting or suppression
  • syncing conversion events for measurement and optimization

Because each advertising platform supports different types of data, the options you see here can vary by destination.

  1. Go to Activation → Syncs and select a sync.
    Alternatively, create a new sync.

  2. Open the Configuration tab.

  3. Under What would you like Hightouch to send to your destination?, select the option that matches your use case.

Select what Hightouch should send to your destination


Send enriched identifiers

After you choose what to send, scroll to the field mapping section to select which columns you would like to use to match to users in your destination.

  1. Toggle on Enable Match Booster for higher audience reach ✨.

    Enable Match Booster in a sync

  2. Review which identifiers will be sent for matching.

    In most destinations, Hightouch automatically includes the best available boosted identifiers for Match Booster.
    Some destinations may allow you to remove specific identifiers if needed.

  3. Click Save changes.

If you just enabled Match Booster for the first time, wait for the initial enrichment run to complete before running your sync. Boosted identifiers won’t be available until enrichment finishes, and match rate improvements may take time to appear in the destination.


View match rates

Hightouch surfaces match rates for syncs to paid advertising destinations, whether or not Match Booster is enabled.

To view match rates for a sync:

  1. Go to ActivationSyncs.
  2. Select the sync you want to review.
  3. Open the Overview tab.
  4. In the right-hand panel, locate Matched users.
  5. Click See details.

Matched users on sync overview page

Clicking the match rate opens a details view that shows:

  • external status of the sync
  • matched users
  • match percentage
  • links to your audiences in the ad platform
