GPT on Question 33, Sep 19

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

Employee count alone should not drive the decision; business model, message volume, CRM, and channel complexity matter more.

Practical shortlist

SituationBest starting point
B2B enterprise, complex lead nurturing/account-based marketingAdobe Marketo Engage
Salesforce-centric organization, B2C or broad multichannel journeysSalesforce Marketing Cloud Engagement
Consumer digital product with real-time, behavior-triggered messagingBraze
Mid-complexity B2B, prioritizing usability and fast deploymentHubSpot Marketing Hub Enterprise
Large e-commerce/retail operationKlaviyo or Braze, depending complexity
Highly customized cross-channel orchestrationIterable or Braze

My default recommendation

For a typical 5,000-person B2B enterprise, I would shortlist:

  • 1.Adobe Marketo Engage – strongest fit for sophisticated B2B lead management and nurturing.
  • 2.HubSpot Enterprise – easier administration and faster time to value, but validate scalability, governance, and contact-based pricing.
  • 3.Salesforce Marketing Cloud – prioritize it if Salesforce is already your strategic CRM/data platform, although implementation and operating costs can be substantial.

For a B2C enterprise, start with Braze and Salesforce Marketing Cloud, adding Iterable as a competitive bid.

Procurement criteria to weight

  • •Functional fit: 25% — segmentation, journeys, testing, personalization, approvals
  • •Integration/data architecture: 20% — CRM, CDP, warehouse, APIs, event latency
  • •Security/compliance: 15% — SAML/SSO, SCIM, RBAC, audit logs, SOC 2, ISO 27001, CPRA/CCPA, CAN-SPAM, consent controls
  • •Total cost of ownership: 15% — contacts, sends, data storage, API usage, implementation, support, partner costs
  • •Deliverability: 10% — dedicated IPs, reputation management, suppression handling, advisory support
  • •Usability/governance: 10% — business-unit separation, templates, approval workflows, localization
  • •Vendor viability/service: 5%

Contract risks to negotiate

Avoid pricing based on unrestricted “marketable contacts” without deletion and suppression rules. Cap renewal increases, lock implementation rates, define SLA/service credits, obtain data-export and transition assistance, and require advance notice for subprocessor or product changes.

Bottom line: Choose Marketo for B2B complexity, Braze for consumer lifecycle marketing, or Salesforce Marketing Cloud when Salesforce alignment and broad enterprise orchestration outweigh cost and administrative complexity. I would not make Mailchimp the default platform for an enterprise of this scale.
