GPT on Question 33, Sep 15

I'm a VP of Procurement at a 5,000-person enterprise in the US. What email marketing platform should I use?

Short answer

For a typical 5,000-person B2B enterprise, I would start with Adobe Marketo Engage as the default choice—particularly if you need complex lead nurturing, lead scoring, CRM integration, multiple business units, and enterprise governance.

However, your CRM and business model should drive the final selection:

SituationBest fit
B2B, complex sales cycles, mature RevOpsAdobe Marketo Engage
Deeply standardized on Salesforce and need cross-channel journeysSalesforce Marketing Cloud
Ease of use and rapid deployment matter more than maximum complexityHubSpot Marketing Hub Enterprise
B2C, high-volume, real-time lifecycle messagingBraze or Iterable
Retail/e-commerceKlaviyo
Adobe-centered digital experience stackAdobe Journey Optimizer

My practical recommendation

Shortlist:

  • 1.Adobe Marketo Engage
  • 2.HubSpot Marketing Hub Enterprise
  • 3.Salesforce Marketing Cloud—only if your Salesforce architecture and internal skills make it advantageous

Run a paid proof of concept using actual workflows and data. Don’t select solely from demos.

Procurement criteria

Score vendors on:

  • •CRM/CDP/data warehouse integration
  • •Deliverability services and dedicated-IP support
  • •SAML SSO, SCIM, granular RBAC, and audit logs
  • •SOC 2, privacy terms, breach obligations, and subprocessor controls
  • •Consent management and CAN-SPAM/GDPR support
  • •Business-unit separation and approval workflows
  • •API limits and charges for contacts, sends, data storage, sandboxes, and integrations
  • •Implementation and migration cost
  • •Required agency or certified-admin dependency
  • •Service levels and premium support
  • •Data export and transition assistance at termination

Negotiate pricing against marketable contacts, email volume, business units, and API usage, not employee count. Require price protection for growth and deletion of dormant contacts from billing.

Bottom line: Choose Marketo for a conventional complex B2B enterprise; choose HubSpot Enterprise if usability and lower operational overhead are the priority; choose Braze/Iterable rather than either if this is primarily B2C lifecycle marketing.
