From vendor documentation, checked 2026-11-12. Audience sizes, sending periods, and product editions differ by plan, so the prices are not quotes for the same workload. Salesforce figures are for Marketing Cloud Next, and SendGrid figures are for Marketing Campaigns. "Not verified" means we couldn't confirm the value. It does not mean the feature is missing.
