Re: Notification on removal of system-ipv4-works && system-ipv6-works tags while connected

Hello all, We use Brevo to send these emails primarily because it ensures deliverability and allows people to easily unsubscribe. This is important because big email providers have recently increased their penalties for potential spam, so we track bounces and unsubscribes to make sure the RIPE NCC stays within acceptable limits. It is not possible for us to turn off the tracking pixel in Brevo on our end, but we use it only to view the status of delivery, opens and unsubscribes. We are aware this tracking is not 100% accurate, but it gives us a general view of whether emails are reaching their recipients, which helps us to stay below the spam threshold. If you’d rather get a plaintext version of these emails from Brevo, some email clients provide an option to switch to the plaintext view. This will also block the tracking pixel. Regards, Antony Gollan Communications Team Manager RIPE NCC

Tracking pixels are completely unnecessary to handle bounces, and "easy unsubscribe". VERP exists since, what, 25? years? Send each e-mail with a unique sender, bounces can be directly mapped to the attempted receipient address. Also, the ATLAS mails that started the discussion are not even "list mails that you might want to unsubscribe from, or track delivery" - it's individual mails with individual probe information to probe owners. Nothing bulk here.

"Undeliverable mails" and "spam threshold" is something quite unrelated, and the tracking thing isn't working as well as they are selling it to you (given that most MUAs have learned to *not* load this crap).

The ATLAS mails did not have a plaintext body. Just HTML. Very annoying. Gert Doering -- NetMaster -- have you enabled IPv6 on something today...? SpaceNet AG Vorstand: Sebastian v.
