How to blok undesirable emails?

The Mail app on the iPad doesn't have a spam filter, so you will need to do any filtering before the emails get to it - does your email client offer any sort of filtering e.g. if you log into your account on a browser are there any settings and/or filters that you can set ?

The mail program does not have ablocker. It only shows you what your mail system has accepted. Go to your mail provider and set up any blocking there. As an example, gmail has a pretty good blocker and spam filter. That acts on e mail before it gets to the pad.

1) Log into iCloud from a desktop computer (www.icloud.com)

2) Select the (mail) icon

3) Select the inbox & then the email within the inbox which you wish to block

4) Select the hyperlink drop-down, "Mark as"

5) Select "Junk Mail"

(you may also perform #5 by selecting the gear icon in the top right corner)

From there on out, this sender will automatically be moved into the "Junk email" folder. Good luck!
