# Contact Enrichment

> Enrich existing contacts in Rex CRM with Propexa.

Contact enrichment is a Propexa workflow that adds new contact details to
existing people in Rex CRM. To start,
apply a tag to the contacts you want processed. Propexa handles the search,
matching, and writeback automatically.

<Info>
  Enrichment runs nightly. Contacts tagged by end of day are processed after hours.
</Info>

## Before you begin

For the strongest chance of a match, check that each Rex contact:

* Is a person contact
* Has the correct full name
* Includes a property or address, when available

## Start an enrichment

<Steps>
  <Step title="Choose contacts in Rex">
    Find the person contacts you want to enrich. You can select contacts
    individually or prepare a group, such as the owners on a particular street.
  </Step>

  <Step title="Apply the enrichment tag">
    Add the `Propexa Enrich` tag to each selected contact. No other action is
    required. [See the Rex documentation on tagging here](https://support.rexsoftware.com/hc/en-us/articles/360032995034-System-Tags-Tagging-via-Mass-Action).
  </Step>

  <Step title="Wait for the scheduled run">
    Propexa collects tagged contacts nightly and creates an
    enrichment run. A contact already being processed will not be added twice.
  </Step>

  <Step title="Review the contact in Rex">
    After a successful match, Propexa writes any new details to the existing Rex
    contact, removes `Propexa Enrich`, and applies the `Enriched` tag.
  </Step>
</Steps>

<Note>
  If a contact cannot complete the flow, the `Propexa Enrich` tag remains in Rex
  so the contact can enter a later run.
</Note>

## Example use case

<Card title="Prepare a campaign audience" icon="megaphone">
  Before a just-listed or just-sold campaign, tag the owners on the desired street. Propexa
  processes them after hours so enriched contacts are ready for campaign kick-off the next day.
</Card>

## Frequently asked questions

<AccordionGroup>
  <Accordion title="What types of contacts are eligible for enrichment?">

    * People (companies and trusts are not supported)
    * Have an address, either by a linked property or in the address field
    * Have full name(s)
  </Accordion>

  <Accordion title="Why does enrichment run after hours?">
    Running after hours helps Propexa work within current provider and volume
    limits while processing contacts reliably.
  </Accordion>

  <Accordion title="Not all my tagged contacts get enriched. Why?">
    We were likely unable to get a match, either because we didn't find one or
  </Accordion>

  <Accordion title="What happens when there is no match?">
    Propexa skips the contact and does not write any new data to Rex. The
    `Propexa Enrich` tag remains so the contact can be included in a later run.
  </Accordion>

  <Accordion title="Will Propexa remove existing phone numbers or email addresses?">
    No. Enrichment is additive: Propexa only adds new contact information and
    never deletes existing phone numbers or email addresses as part of this flow.
  </Accordion>

  <Accordion title="Propexa did not pick up on a match and it needed to be done manually">
    Please send us an email with the details of the person, including their address, to **[hello@propexa.ai](mailto:hello@propexa.ai)** and we will investigate for you.
