Claude changed its list for a large enterprise’s request for an email platform.

The honest answer is that "email marketing platform" covers three very different procurement categories, and the right shortlist depends on which one your stakeholders actually need. Worth nailing down before you go to market:

• 1.Marketing/campaign email — outbound to prospects and customers, usually owned by Marketing, tied to CRM
• 2.Transactional/product email — password resets, receipts, notifications, sent via API by Engineering
• 3.Internal employee communications — all-hands emails to your 5,000 staff, usually owned by Comms/HR

These have different vendors, different price structures, and different security reviews. If your intake request just said "email marketing platform," it's worth a 20-minute call with the requester to find out which.

Shortlists by scenario

B2B marketing (long sales cycles, lead scoring, CRM-centric)

• •Marketo Engage (Adobe) — deepest B2B automation; expect significant implementation cost and a specialist admin
• •Salesforce Marketing Cloud Account Engagement (formerly Pardot) — the default if you're already heavily invested in Salesforce
• •HubSpot Marketing Hub Enterprise — fastest time-to-value, best usability, less customizable at the edges
• •Eloqua (Oracle) — strong if you're an Oracle shop, otherwise fading in mindshare

B2C / high-volume consumer lifecycle

• •Braze — strong cross-channel (email, push, in-app), engineering-friendly
• •Iterable — similar space, often easier for marketers to self-serve
• •Klaviyo — dominant in ecommerce/DTC, moving upmarket
• •Salesforce Marketing Cloud Engagement — powerful, but complex and implementation-heavy

Transactional/API

• •SendGrid (Twilio), Amazon SES (cheapest by far if you have engineering capacity), Postmark, Mailgun

Internal employee comms

• •Staffbase, Firstup, PoliteMail, ContactMonkey — these integrate with Outlook/Exchange and give you open/read analytics on internal mail, which general marketing tools handle poorly

Procurement-specific things that bite people here

Pricing model is the main trap. Marketing automation is usually licensed on database size (contacts stored), not emails sent. That means your cost ratchets up as Marketing imports lists, and vendors rarely let you tier back down mid-term. Push for: a contact tier with headroom, explicit language allowing downgrade at renewal, and a defined (cheap) overage rate rather than a forced tier upgrade.

Implementation is often the bigger number. For Marketo or Marketing Cloud, systems-integrator fees commonly run 1–2x first-year license. Get SI quotes before signing the license, and consider making the license contingent on a fixed-fee SOW.

Renewal uplift caps. Get a cap (aim for 3–5%) written in for at least two renewal cycles. Without it, year-four increases of 15–20% are common.

Timing leverage. Salesforce's fiscal year ends January 31; Adobe's ends late November/early December. HubSpot and the mid-market players push hard at calendar quarter-end. Aligning your signature date accordingly is real money.

Bundling. If you already have an Adobe or Salesforce enterprise agreement, adding this SKU into that vehicle at the next true-up is usually cheaper than a standalone deal — but it also lengthens your lock-in and makes future switching harder. Worth a deliberate decision rather than a default.

Security/compliance review items: SOC 2 Type II, ISO 27001, subprocessor list, data residency (relevant if you have EU or UK data subjects — check GDPR/UK GDPR transfer mechanisms), DPA with standard contractual clauses, breach notification SLA, SSO/SCIM support, and audit-log retention. If you're in healthcare or financial services, add HIPAA BAA or applicable regulatory requirements to the RFP.

Deliverability. Ask each vendor for dedicated IP options, IP warming support, and whether deliverability consulting is included or a paid add-on. At your volume this materially affects whether the tool works at all.

Exit terms. Data export format and cost, transition assistance period, and termination-for-convenience rights. Also check auto-renewal notice windows — 60–90 days is typical and easy to miss.

Practical next step

If this is a competitive process, three bidders is the sweet spot — enough for price tension, not so many that stakeholder evaluation collapses. Run a scored RFP with Marketing as the functional evaluator and hold pricing negotiation separately after technical selection, so you're not negotiating against a foregone conclusion.

If you can tell me which of the three use cases this is, and whether you're already on Salesforce, Adobe, or Microsoft Dynamics, I can narrow the shortlist considerably and flag the specific contract clauses that matter most for those vendors.
