That's quite suspicious.  Perhaps Kaul had a burst of online business and posted to INDOLOGY and at the same time uploaded the review to Academia, which triggered your notification.  We can't tell from Academia when papers are uploaded, but the review has 317 views, which suggests it was uploaded a while ago, not recently.  So that explanation is probably wrong.

How could Academia possibly be getting information about your incoming emails?  What mechanism can we imagine?  Emails don't deposit cookies, so cross-site cookies aren't the pathway.  If Academia is harvesting from the INDOLOGY archive, which is technically possible, then *everyone* would get the Kaul notification or similar ones, not just you.  It's hard to see how this might work.  Without a plausible mechanism, I'm staying with coincidence.

But I have all my Academia notifications turned off, so I never get anything from them.  If I want to know their stuff, I look at the website.

Best,
