GPT on Question 33, Sep 18

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. Choose based on customer type, message volume, CRM/data stack, and journey complexity.

My practical recommendation

Primary use case	Best-fit platform
B2B lead nurturing and account-based marketing	Adobe Marketo Engage
B2C, high-volume, real-time lifecycle messaging	Braze
Deep Salesforce ecosystem and complex enterprise workflows	Salesforce Marketing Cloud Engagement
Existing Adobe Experience Cloud/CDP investment	Adobe Journey Optimizer
Ease of use and lower administrative burden	HubSpot Marketing Hub Enterprise

Default choice for a typical 5,000-person B2B enterprise: Adobe Marketo Engage, particularly if you have sophisticated lead scoring, long sales cycles, multiple business units, and Salesforce CRM.

Default choice for a digital B2C enterprise: Braze, especially when email must coordinate with mobile push, in-app, SMS, and real-time behavioral data.

What I would shortlist

Run a structured evaluation with:

1.Marketo Engage
2.Salesforce Marketing Cloud
3.Braze or Adobe Journey Optimizer, depending on whether you are B2C or already Adobe-centric
4.HubSpot Enterprise as the usability and TCO benchmark

Procurement criteria that matter most

Weight the RFP approximately as follows:

•Functional fit and journey orchestration: 25%
•Integration with CRM, CDP, warehouse, and identity stack: 20%
•Deliverability and consent management: 15%
•Security and governance: 15%
•Three-year total cost of ownership: 15%
•Usability, implementation risk, and support: 10%

Require SSO/SAML, SCIM, granular RBAC, audit logs, SOC 2 Type II, appropriate ISO certifications, DPA support, CCPA compliance, suppression-list controls, sandboxing, and business-unit separation.

For pricing, normalize every proposal against the same assumptions: marketable contacts, annual message volume, data retention, business units, API usage, sandboxes, premium support, implementation, and required partner services. Platform license price alone is often misleading; Marketo and Salesforce in particular can require significant administrative and integration resources.

Bottom line: Choose Marketo for enterprise B2B, Braze for modern B2C lifecycle marketing, or Salesforce Marketing Cloud when Salesforce alignment outweighs ease of administration. Avoid selecting HubSpot solely for simplicity if you expect highly complex governance, data models, or global campaign operations.
