•  Support Good for anti-spam, could be used in an unsubscription tool. -wd-Ryan (Talk/Edits) 17:58, 2 November 2022 (UTC)

• @Dhx1 You have currently orgnaization in the domain but no examples of it. Please either add examples for each of the domains or remove those entries from the domain. I think it's completely reasonable to have this property on mailing lists but I'm more skeptical about having it on items for larger organizations. ChristianKl ❪✉❫ 13:34, 5 November 2022 (UTC)

  @ChristianKl: I've added some organisation examples too. I agree with your sentiment that there are fewer organisations with easily available information on how to unsubscribe, and quite often it is only possible to unsubscribe via a unique identifier code sent in an e-mail (either in return e-mail or visiting a provided site URL in a browser). --Dhx1 (talk) 15:43, 5 November 2022 (UTC)
