We do not substitute a headline score for the evidence behind it.
For people responsible for email
Deliverlens is intended for senders, developers and investigators working with email they are authorized to test. Public tools, account diagnostics and API access connect a specific question to a bounded result; they are not a source of permission to test someone else’s infrastructure or addresses.
How the evidence moves
A public or account request is validated by its Laravel frontend and sent server to server to the central API. The API applies the account, plan, permission and usage decision, records a diagnostic run, and returns only the report fields that route is allowed to show. Browser code never receives the central service credential.
Useful limits, plainly stated
Authentication, verification, blocklist checks and seed observations each measure something different. Coverage, timing and unavailable signals belong beside the result. No tool can promise that every future message will reach every inbox.
Learn before changing production
The academy is organized around practical questions, worked examples and primary sources. Drafts stay separate from published lessons. Production changes should follow your organization’s authorization and rollback process.
Questions and corrections
The FAQ provides concise product answers, while guides and Academy tutorials carry the deeper method. Contact can be used for a support question or editorial correction when the configured delivery route is available. Do not send credentials, raw private messages or unrelated personal data.
