Since early February (roughly the 5th or 6th) we have been
experiencing an open rate drop of roughly 13-17% at Gmail. Our Gmail
reputation tools show no changes and we have made no changes on our
end that would affect these rates. Clicks, revenue and conversions
have not shown the same drops so this almost seems like something on
Gmail's end.
I wanted to offer some oblique information as well. In the past few
weeks, (Feb 6) we've seen Google implement a DMARC policy change for
gmail.com that includes sp=quarantine.
I picked this up because our mailing lists modify sender emails for
those with a p=reject|quarantine.
I think we have an error in our parsing because we are hitting on the
sp= value which likely shouldn't be showing up anyway.
Perhaps others have better records of the change too. I thought the
date you mentioned was very interesting.
