What are IETF, M3AAWG, and CSA?

IETF (Internet Engineering Task Force) develops internet technical standards including email protocols. They manage the RFC process and coordinate global protocol development through working groups and open participation.

M3AAWG (Messaging, Malware, and Mobile Anti-Abuse Working Group) focuses on combating messaging abuse. They publish best practice documents, facilitate information sharing among providers, and coordinate responses to emerging threats. M3AAWG membership includes major ISPs, ESPs, and security companies.

CSA (Certified Senders Alliance) is a European organization offering sender certification and best practice frameworks. CSA certification helps senders demonstrate compliance with standards, potentially improving deliverability to participating providers. Their guidelines emphasize consent, transparency, and technical quality.
