Verify the final deal before you buy.
EmailCostEngine improves comparison quality; it cannot freeze third-party pricing or replace a provider's checkout, contract or support confirmation.
Third-party pricing changes
Providers may change plans, currency treatment, tax, promotional pricing, subscriber definitions, usage limits and feature availability after a source was checked.
Estimates and projections
Growth and migration outputs depend on the inputs and verified coverage available to the engine. A projected saving is not guaranteed future cash savings.
Feature compatibility
A feature marked included reflects captured evidence at the plan level; implementation details, regional availability, account eligibility and usage restrictions can still matter.
Final confirmation
Before purchasing, cancelling or migrating a production email system, confirm final pricing, contractual terms, data-export/import requirements, deliverability considerations and critical integrations directly with the relevant provider.
