This is my first time posting, so I apologize if this is in the wrong place, but I was wondering if anyone has seen any impact from the release of the efail email encryption vulnerabilities yet? A big part of my concern, is the recommendation by the authors to turn of HTML rendering, and what that will do to our tracking / interaction data.
No end-to-end encryption technologies are used by Marketo-generated emails so I would have zero concern about this.
It's no more significant than, say, an HTTP client cert vulnerability when you're not using client certs.
That makes sense. I guess my biggest concern is the adoption, by my recipients, of the solution of not allowing HTML rendering. I understand there's not much I can do about if it is happening, but I would like to be aware if it is.
The chance of a mailbox owner who's affected by this vulnerability also [a] getting your emails in the first place and [b] disabling HTML rendering now, for the first time, for all email (not just encrypted email) is basically zero.
