Not getting email watchlist

@Kathykdt Thanks for the problem report; there are some troubleshooting steps on https://help.imdb.com/article/imdb/general-information/manage-your-email-subscriptions-and-watchlist-notifications/GFSALECHJBMR4U5B especially note the point:

• Subscription emails are only sent to users that have been active on the site within the last two years. If you have not visited a page while logged into your IMDb account within the last two years, this may resolve the issue.

Hope this helps.
