Facebook recently changed a lot of the permissions it gives to apps like EasilyDo and this is what is effecting the way you can send Birthday posts. Unfortunately, there is nothing we could do to continue using this permission.
Previously, EasilyDo was able to get information from Facebook telling us which of your friends have birthdays coming up. Now, Facebook is not allowing any apps (including us and others like Flipboard) to have this information so EasilyDo finds birthdays from your Contacts and Calendar. This means that you will not always be able to post to your friends' Facebook pages directly and will sometimes only be able to send an email.
EasilyDo is still able to find the birthdays from your Contacts and Calendar, but we won't always be able to post to Facebook. If you only see the Email option and can't click on the Wall Post option, then sending an email is the only option available.
Our apologies for any inconvenience here.
