Email Enrichment Vendor Privacy Review

Review an email-enrichment vendor as a data source and processor, not just as a feature list. Before import, document what the vendor supplies, where it came from, why your organization needs it, and which party decides the marketing purpose. A vendor’s claim that contacts are “compliant” is evidence to examine, not a legal conclusion.

Request evidence in five areas

Request source and collection documentation: source categories, collection context, freshness, accuracy process, and whether the data is inferred or directly provided. Request role and contract documentation: processing instructions, access, security terms, subprocessors, deletion or return, audit support, incident handling, and any restrictions on using objections or suppression data. Request geography documentation: vendor entities, subprocessors, hosting locations, and transfer mechanisms.

Then map the operational path. Which fields enter the CRM? Which fields are used for personalization? When does the vendor receive a suppression or objection? Can an opted-out person be reintroduced by a later enrichment run? The ICO’s guidance treats bought-in lists, public details, consent, and objections as separate review topics; “B2B” does not erase the need to ask them.1

Approve with limits

Record approved source types, recipient categories, fields, countries, and purposes. Mark unknowns as blockers or accepted risks with a named owner and review date. Do not approve the vendor for all campaigns if the evidence only supports one narrow use. Test a small, non-sending data flow for suppression and deletion behavior before activating outreach.

If a vendor cannot explain source provenance, objection propagation, or downstream access, quarantine the data. If the use involves extensive profiling, sensitive information, or cross-border transfers, add a privacy review. RepMail can send or store campaign data depending on the configured workflow, but verify current terms and capabilities before representing the platform as a processor or deletion mechanism. Use the provenance checklist, agency responsibility guide, and personalization data checklist.

Implementation notes

Ask for a sample evidence packet before signing off: one source description, one freshness value, one objection path, one deletion answer, and the current subprocessor list. Compare those answers with the fields your campaign actually uses. A contract that covers only email delivery may not cover enrichment, profiling, or vendor analytics. Record limitations in the approval so another campaign owner cannot overgeneralize it.

For adjacent controls, use the broader cold-email compliance checklist.
