[Bimi] BIMI Reporting

[Tom Bartel <[e-mail]>]

After reviewing the BIMI Reporting draft:


https://datatracker.ietf.org/doc/html/draft-adams-bimi-reporting


I think that it may be missing some useful data that would greatly benefit
BIMI (and DMARC) adoption. Through discussions with senders interested in
BIMI, it’s become apparent that they’ll need to measure the effectiveness
of their deployment (to justify their spend), and I don’t think that the
current reporting draft includes the necessary level of data.


I’d suggest the addition of an aggregate count per reporting period (e.g.
24 hours) of BIMI logos that were displayed by the MUA. This would be in
addition to the aggregate BIMI record evaluations already in the draft.


Senders ultimately want to know if the “juice will be worth the squeeze” -
that is, not only implementing DMARC, but the additional effort of implementing
BIMI, too.


I know that this level of reporting may happen elsewhere in the email
pipeline than where DMARC and initial BIMI evaluation occurs, though I
think it’s important enough to explore whether it can be added.


What do folks think? Does it make sense to add this additional reporting
signal to the BIMI Reporting draft?
