Dead Internet Theory: Deliverability consulting helps legitimate senders understand authentication, reputation, complaints, and inbox placement, but better delivery is not the same thing as proving recipients wanted the message.
Dead Internet Theory: SPF, DKIM, and DMARC can help establish that a message is authorized by a sending domain, but authentication does not prove that the recipient asked for the message or still wants it.
Dead Internet Theory: Complaint counts and complaint rates measure different things: a huge sender can generate many complaints while maintaining a low percentage, while a small sender can trigger the same rate with only a handful of unhappy recipients.
Dead Internet Theory: Blocklists help receiving systems reject abusive mail, but shared IP addresses and hosting networks can create collateral damage when unrelated senders inherit the consequences of another customer's behavior.
Dead Internet Theory: An old permission record can outlive the person or mailbox it originally described, making stale and recycled addresses a warning that consent is not permanently attached to a string of characters.
Dead Internet Theory: Spam is cheap for senders partly because much of the real cost is paid elsewhere: recipients spend attention, moderators spend labor, and service providers fund filtering, storage, abuse handling, and infrastructure.
Dead Internet Theory: Abuse reports are most useful when they include technical context, but reporting systems often demand details ordinary recipients do not have and may provide little feedback after submission.
Dead Internet Theory: Spam can remain economically attractive even when almost nobody responds because distribution is cheap, conversion only needs to occur occasionally, and much of the filtering and attention cost is paid by other people.
Dead Internet Theory: Commercial content, unsolicited content, and recipient-defined unwanted content overlap without being identical, so serious measurements of spam need explicit definitions instead of treating every advertisement as the same phenomenon.
Dead Internet Theory: Claims that large senders receive softer treatment than small ones require comparable evidence: the same complaint definitions, consent conditions, message types, time windows, and enforcement outcomes rather than raw volume alone.
