Why didn't I get an email sent from LastPass?
If LastPass was supposed to send you an email notification (for verification, sharing an item, Master Password changes, etc.) and you didn't receive it, you can check the following:
Check your Security email address (if applicable)
If you have set up a Security email address, please check that inbox as the email was sent there.
Check your Email Notifications settings
You can manage your Email Notifications subscriptions to ensure you didn't unsubscribe from an email that you expected to be triggered.
Check your spam/junk email filters
Please be sure that you have added email@example.com and firstname.lastname@example.org as contacts and to your email filter's whitelist, then prompt LastPass to send you another email.
