Claude named a different first choice for a large enterprise’s request for an email platform.

The right answer hinges almost entirely on one question: is this B2B demand generation or B2C/consumer lifecycle messaging? Those are different product categories with different vendors. A few other things matter too (existing CRM/martech stack, send volume, whether you need transactional email), but B2B vs. B2C is the main fork.

Here's how the landscape breaks down at your scale:

If it's B2B marketing (lead nurture, ABM, sales handoff)

• •Adobe Marketo Engage — the default enterprise B2B choice. Deep campaign logic, strong Salesforce sync. Clunky UI, needs a dedicated admin.
• •Salesforce Marketing Cloud Account Engagement (Pardot) — weaker than Marketo functionally, but if you're a heavy Salesforce shop the native integration and single-vendor consolidation can outweigh that.
• •Oracle Eloqua — very strong at complex routing and governance. Aging ecosystem; fewer people know it.
• •HubSpot Marketing Hub Enterprise — the usability outlier. Genuinely faster time-to-value and lower admin burden. Historically criticized for hitting ceilings at large database sizes and complex org structures, though it's moved upmarket significantly. Worth a serious look if your marketing team is small relative to headcount.

If it's B2C/consumer lifecycle (high-volume, cross-channel)

• •Braze — strong modern choice for cross-channel (email, push, in-app, SMS). Good API/developer story.
• •Iterable — similar space, often cited as slightly friendlier for marketer self-service.
• •Salesforce Marketing Cloud Engagement — powerful and very configurable, but implementation-heavy. Budget for a systems integrator.
• •Adobe Journey Optimizer — only makes sense if you're already committed to Adobe Experience Platform. Otherwise the platform tax is severe.
• •SAP Emarsys or Klaviyo — if retail/ecommerce specifically.

Procurement-specific things I'd flag

These are where I'd focus your leverage, since the functional evaluation should really be owned by marketing:

Pricing model is the biggest trap. Vendors price on different units — contacts in database, sends per month, monthly active users, or credits. Model your 3-year growth curve against each. A platform that's cheaper at year one can be 2x at year three depending on which metric grows fastest for you. Specifically negotiate: overage rates (not just base rate), a cap on renewal uplift (aim for 3–5%), and what happens if your contact count drops.

Implementation cost is often the larger number. For Salesforce Marketing Cloud or Adobe, SI fees commonly run 1–2x first-year license. Marketo is somewhat less. HubSpot is usually a fraction of that. Get SI quotes during vendor selection, not after — it frequently changes the ranking.

Don't let the license get bundled into an enterprise agreement you can't unwind. Both Salesforce and Adobe will offer attractive bundling. It's real savings, but it compounds switching costs and weakens you at every future renewal.

Diligence checklist: SOC 2 Type II, ISO 27001, DPA with current SCCs, subprocessor list and change-notification terms, data residency, SSO/SAML plus SCIM provisioning, VPAT/accessibility conformance, data export rights and format on termination, and uptime SLA with actual credits (not just a published target). If you're in healthcare or financial services, confirm BAA availability or relevant attestations early — it eliminates several vendors.

Deliverability. Ask about dedicated IP allocation, IP warming support, and whether deliverability consulting is included or a paid add-on. At 5,000 employees you may have multiple business units sending; shared-IP reputation problems become a real operational risk.

Timing. Both Salesforce and Adobe have January 31 fiscal year ends; most others are calendar. End-of-quarter and end-of-year are your best discount windows. Expect 20–40% off list as normal, more on multi-year.

To narrow this down

It would help to know: B2B or B2C? What CRM are you on today? Rough contact database size and monthly send volume? Are you replacing something specific, and what's driving the change? And how large is the marketing ops team who'd actually run this — that single factor often decides between Marketo/SFMC and HubSpot more than any feature comparison.

One honest caveat: the cost figures and discount norms I've described are directional and move over time, and vendor positioning shifts year to year. Treat this as a framework for structuring your RFP rather than final numbers. Your marketing and marketing-ops stakeholders should own the functional scoring — your leverage is in commercial structure, and that's where the money usually is.
