Facebook always asks me to update my email address
Every time I resubmit an email address it tells me its invalid. Could this be a problem with my email?
Yes and No :^)
Yes > Some users are seeing a “Please update your email address” message after logging in because their email service provider is most likely treating Facebook emails as spam. To resolve this issue, please contact your email service provider and let them know about your problem receiving emails from Facebook.
No > It appears Facebook never sends the confirmation emails out. It is a bug in their system and it has been reported. Just keep trying.
