GPT on Question 33, Oct 3

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 shouldn’t determine the platform; audience size, B2B vs. B2C, CRM, message volume, and automation complexity matter more.

Recommended shortlist

SituationBest fitMain consideration
B2B demand generationAdobe Marketo EngageStrong lead scoring, nurture, and enterprise controls; requires skilled admins
Large-scale B2C lifecycle messagingBrazeExcellent real-time journeys across email, push, SMS, and in-app; premium pricing
Company is standardized on SalesforceSalesforce Marketing Cloud EngagementDeep Salesforce alignment and enterprise scale; implementation can be complex
Ease of use and faster deploymentHubSpot Marketing Hub EnterpriseStrong usability and integrated CRM; costs can grow with marketable contacts
Retail/e-commerceKlaviyoStrong commerce segmentation and revenue attribution; less suitable for general enterprise B2B
Procurement/supplier newsletters onlyExisting corporate platformAvoid creating a separate platform and data/compliance footprint

My default recommendation

  • •B2B enterprise: Start with Adobe Marketo Engage.
  • •B2C/customer lifecycle: Start with Braze.
  • •Salesforce-centric organization: Include Salesforce Marketing Cloud, but don’t select it solely because Salesforce is already contracted.
  • •Smaller marketing operations team prioritizing usability: Choose HubSpot Enterprise.

I would generally not make Mailchimp the strategic enterprise standard for a 5,000-person company, though it may be adequate for isolated, low-risk newsletter use.

Procurement requirements to put in the RFP

Require vendors to price and demonstrate:

  • •Annual marketable contacts, send volume, business units, and overage rates
  • •SAML SSO, SCIM, granular RBAC, approval workflows, and audit logs
  • •SOC 2 Type II, ISO 27001, CCPA support, DPA, subprocessors, and breach notification
  • •Dedicated IPs, domain authentication, deliverability services, and SLA
  • •CRM/CDP/data-warehouse integration and API limits
  • •Preference centers, consent history, suppression management, and retention controls
  • •Sandbox, implementation, migration, training, and premium-support costs
  • •Renewal caps, data-export rights, transition assistance, and deletion certification

Run a paid or tightly scoped proof of concept using two or three real campaigns. Score deliverability, marketer usability, integration effort, governance, and three-year total cost, not just license price.
