A few months ago, I changed my email to a yahoo one that I've used for many years. Over the next few weeks, my notifications dwindled until I received none. I had to revert to a gmail email and now regularly get notifications. However, I only see likes on logging in; I don't get email notifications on them. I'm not sure we're meant to get email on likes. I use My FlyerTalk and I see all of my likes in the upper right hand corner under SanDiego1K.
