Good comparisons are made field by field.
SendInbox is being built around structured evidence rather than a single opaque score. This is the publication standard the production catalog will follow.
Source from the product
Official product, pricing, company, documentation, and integration pages are the preferred sources. Every extracted value retains its source URL and retrieval date.
Normalize without flattening
Capabilities, usage limits, seats, contacts, credits, and sending volume are stored separately. Pricing is compared through explicit scenarios, not one misleading starting price.
Review consequential facts
Prices, product limits, categories, and ranking inputs require editorial review before publication. Automated extraction proposes facts; it does not publish them.
Publish the evidence state
Public facts carry a verification state and date. Missing evidence stays missing rather than being filled with assumptions.
Refresh as snapshots
New pricing and capability checks create dated snapshots so changes can be explained and audited instead of silently overwriting history.
