Does anyone of you have practical experience with Google's feedback

anything wrong or if it's just the low volume?
What I can recommend from my own experience:
1) create some actual test account on Gmail
2) make your customer send an email to this account using your process
3) access the Gmail account and see if message actually went to Spam folder.
If yes:
4) check if Gmail indicates all three SPF, DKIM and DMARC on the message as
PASS. If not, you need to fix the one that is failing on your side and
re-try.
5) If yes, send the headers of the message that was incorrectly classified
as spam (the headers as received on that Gmail account) to Google using this
form: https://support.google.com/mail/contact/bulk_send_new . They
explicitly say in the form that they won't reply to you, but it often really
helps and your messages are no more going to Spam (at least that was in my
case).
Thank you, this is useful. I was not aware of that form. I'll add it to
my bookmarks.
We checked your suggestions back when setting up the system, but I just
rechecked registering an account with my personal Gmail in a sandbox
instance we use to test this type of stuff. The double opt-in
confirmation mail was delivered just fine directly into the inbox.
Checking the email shows a PASS for both SPF and DKIM for
bounce.woltlab.cloud. We don't do DMARC, as explained in my sibling
reply. Gmail shows "Sender Name <[email protected]> via
bounce.woltlab.cloud" as the sender which is expected for our set-up and
nothing unusual, I have seen this for other newsletters I subscribed to
as well.
However unfortunately this does not answer my specific question
regarding the 'Feedback-ID' header / Feedback Loop (i.e.
https://support.google.com/mail/answer/6254652/feedback-loop). The "Spam
Rate" dashboard in Google Postmaster Tools specifically explains:
Dieses Dashboard zeigt den Prozentsatz der von aktiven Nutzern als Spam
gemeldeten E-Mails im Vergleich zu den an den Posteingang gesendeten E-Mails.
[...] E-Mails, die direkt an den Spamordner zugestellt werden, zählen nicht
dazu.
This translates as:
"This dashboard shows the percentage of emails reported as spam compared
to all emails delivered into the INBOX. [...] Emails delivered directly
into the spam folder will not be counted here."
So one (or more) recipients *actively* hit the "This is Spam" button on
~27% of mails we delivered that one day. I wanted to use the Feedback
Loop mechanism *to find out* which of our customers sent those emails to
investigate in more detail. This is the entire purpose of the Feedback
Loop as implemented by Gmail, but it does not work for us due to reasons
that are unclear to me.
And, also don't forget to mark the message as "non-spam" on the test account
that received it, or even reply to the message. It is some signal (although
weak, if only one user does this, but still some) to the Google's AI to not
classify this kind of messages as spam.
This does not apply for my test email, as it went into the INBOX.
However I clicked the activation link within this email to interact with
it, thus sending a positive signal.
