@Deborah498 This happens sometimes. For me it was the opposite-my text alerts stopped but I was still getting the emails.
One thing you can try is to turn off the email notifications, clear your cache and cookies, then turn it back on again, which might reset it.
If that doesn't work, send customer service a message, starting it with "Tech Team Issue". Then, very briefly and simply explain the cessation of the emails and what you tried in order to fix it.
When this happened with my text alerts, it took about a month for them to start up again.
