Finding Prospects to Enrich in Nooks

It is possible to enrich prospects by Sequence and directly in the Dialer itself. We'll cover how to enrich prospects by Sequence below.

Loading Prospects from a sequence​

Within the Enrich tab for Nooks Numbers, you can select a sequence to view prospects within that sequence and select them for enrichment.

Selecting a sequence will load up to 1000 active prospects from that sequence. A prospect is considered active if they have any tasks that are due or upcoming.

Selecting Prospects to Enrich

Enriching Prospects

To start enriching, select one or more prospects from the table and select an enrichment provider to enrich with.

Currently supported enrichment providers are:

  • Apollo

  • Cognism

  • Datagma

  • Forager

  • Prospeo

  • Wiza

  • People Data Labs

  • Zoominfo [only for existing ZoomInfo customers]

    ZoomInfo may be used as an enrichment provider if a team has the ZoomInfo Enterprise plan, by entering API credentials in the Phone Number Data Settings. This will allow users to re-enrich contacts using ZoomInfo if they so choose. This guide contains more information on connecting the ZoomInfo integration.

Credits & Usage

Credits will only be used if both of the following conditions are true:

  1. Nooks finds a mobile number for this prospect

  2. This mobile number is new (it was not in the system previously)

Credits will be deducted from the balance when enrichment is initiated; they will be refunded after enrichment completes for all prospects where no new mobile numbers were found.

Waterfall Enrichment

When you use a waterfall enrichment in Nooks, we attempt to find a mobile number by checking each provider in order, one at a time. As soon as a provider returns a valid mobile number, the waterfall stops and that number is used.

If no number is found, the system continues down the waterfall only if the next provider hasn’t already been used in a previous enrichment for that same lead. This helps avoid duplicate or unnecessary lookups.

For example: If a provider in the middle of the waterfall was used earlier and successfully returned a number, then later attempts to enrich with the full waterfall will stop at that same provider, since a number has already been found.

Waterfalls are currently available only to beta customers, and may be configured in the Settings menu under Nooks Numbers.

Automatic Enrichment

Nooks can automatically kick off your waterfall enrichment for prospects that reps have marked as "wrong number" based on your dialer mapping settings. Under the manager settings, managers and admins can either "select all" or select specific users for the autoenrichment to run. dialer mapping settings.

Dialing Enriched Numbers

If the enrichment process was able to find a phone number for the prospect successfully, the new number(s) should automatically be pulled in any dialer tasks for the prospect.

Any phone number from enrichment will have a lightning bolt icon next to the number (along with a tooltip indicating the source) and will always show up before phone numbers from the SEP.

Enriching from the Dialer

In the dialer, if there are any uncallable prospects, there are links to the phone numbers tab (set to the current selected sequence with “Invalid Mobiles” and “No Mobiles” filters selected).
