GPT on Question 33, Sep 14

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

Company size alone shouldn’t determine the platform. The primary decision is whether you are running B2B demand generation or high-volume B2C lifecycle messaging.

Recommended shortlist

SituationBest fit
B2B lead nurturing, scoring, and complex campaignsAdobe Marketo Engage
B2C lifecycle, mobile/app events, real-time personalizationBraze
Salesforce is your strategic CRM and integration standardization matters mostSalesforce Marketing Cloud Engagement
Ease of use and lower administrative overhead outweigh maximum complexityHubSpot Marketing Hub Enterprise
Very complex global enterprise marketing with an existing Oracle footprintOracle Eloqua

My default recommendation

  • •Typical 5,000-person B2B enterprise: Start with Marketo Engage, with Salesforce Marketing Cloud as the principal alternative.
  • •B2C, product-led, retail, or app-centric enterprise: Start with Braze, with Salesforce Marketing Cloud or Iterable as alternatives.
  • •If you want one platform primarily because Salesforce is already deeply embedded: Choose Salesforce Marketing Cloud, but budget carefully for implementation, specialist labor, and add-on modules.

I would not select Mailchimp or a similar SMB-oriented ESP as the enterprise system of record, though it may remain suitable for isolated departmental use.

Procurement issues that often change the winner

Evaluate three-year total cost, not subscription price alone:

  • 1.Pricing unit: contacts, active profiles, database size, messages, API events, or business units.
  • 2.Implementation: migration, templates, journeys, CRM/CDP integration, IP warming, and deliverability support.
  • 3.Operating labor: required administrators, developers, and agency support.
  • 4.Security: SSO, SCIM, RBAC, audit logs, SOC reports, incident notification, and data deletion.
  • 5.Data rights: AI-training restrictions, subprocessors, retention, portability, and exit assistance.
  • 6.Deliverability: dedicated IP options, sender reputation support, suppression handling, and SLA language.
  • 7.Contract protections: profile-growth bands, overage caps, renewal caps, divestiture rights, and transition periods.

Run a paid proof of concept using three real campaigns and require vendors to quote the same contact volume, message volume, integrations, environments, and support level. For most enterprises, the final decision should be between Marketo and Salesforce Marketing Cloud for B2B, or Braze and Salesforce Marketing Cloud for B2C.
