Mailchimp emails are blocked?

[EssexBod]

Does Yahoo and/or other automatically block emails from Mailchimp?  I use the mailchimp software to send out emails to subscribers - many appear to be blocked include my own email to my sky e-mail address.  Any ideas why?

when you say they are blocked, do you mean they are not being sent, or not being recieved?

Not being received.

And I assume these are not being received by many addresses, not just Sky/Yahoo?

Have you checked that are not just going into spam?

Have you tried querying Mailchimp about it?
