How do standards impact deliverability and sender reputation?

Standards impact deliverability directly because mailbox providers filter based on standards compliance. Authentication standards like SPF, DKIM, and DMARC are now required by major providers. Failing them triggers rejection or spam filtering.

Behavioral standards influence reputation scoring. Senders following best practices for consent, list hygiene, and complaint management build stronger reputations. Those violating standards face reputation damage that persists across providers.

Standards also shape competitive positioning. As compliance becomes baseline, senders who exceed standards gain advantage while those meeting minimums compete on level ground. Standards elevate the entire ecosystem while rewarding those who invest in excellence.
