Frequently Asked Questions
Sender requirements are authentication, infrastructure, message-format, complaint-rate, and unsubscribe rules used by mailbox providers to evaluate email senders.
Check after changing DNS, email providers, authentication settings, or sending infrastructure, and periodically while running active email programs.
Requirements differ by provider and sending volume. If you send to multiple major mailbox providers, following the strongest common baseline is generally the safest approach.
Messages may be deferred, rejected, delivered to spam, or become ineligible for provider-side delivery support or mitigation.
One-click unsubscribe uses standards-based List-Unsubscribe and List-Unsubscribe-Post headers so recipients can unsubscribe with a single provider-supported action.
Select the failed checklist item to see the evidence and recommended next step, then use the related Mailvovo diagnostic tool for deeper analysis.
