Thanks so much for posting this question so that we may address everyone's concern with email.
Unfortunately hotmail, as well as some of the other free email providers such as gmail and yahoo, have changed the way they handle emails in their effort to cut down on spam. What that means is that they have lumped us in with bulk emailers even though you opt-in to receive emails from us.
Here is how it works:
We send out an email to you guys. If the email provider (hotmail, gmail, yahoo), thinks it might be spam they will watch it. If you take no action on that email. For instance click a link inside of it for X amount of days, then receive another email from us (because of a new reply, etc.) and take no action on *that* one too, the email provider attempts to teach itself that we are spamming you.
So the email provider then returns a message to our servers saying that they are rejecting your emails going forward. Our system then takes that info and adds you to the do not mail list after getting 3 of these. The reason for this is that if we don't, they will be block ALL emails we sent through their system and they won't reach anyone.
It's a system that's out of our control. Consumers might be better off using any email that is not one of those for your subscriptions if they want to receive all their emails for which they have opted-in.
Alternatively, some people have luck when they add our emails to their contacts in hotmail, gmail, yahoo, as that is a clue to them that you want to see emails from us.
We can take you off the blacklist but unfortunately without you taking action in (hotmail, msn are the biggest offenders right now) it will just happen again and again. Boo.
Here are some things you can try if you use hotmail:
1) Are we on your blocked senders list? login to hotmail/outlook online and click on the junk tab. In there at the bottom there is a sentence that says "Looking for an email? If you don't find it here, check your blocked senders list." have a quick look and see if we are on there.
2) Check your filters and reporting settings under the gear on the top right. They only keep emails that end up there for 10 days so you have to clear them out and report them as not junk quickly.
3) Using the gear on the top right add us to your safe mailing lists and safe senders lists.
I hope this helps and we apologize for the inconvenience this has caused.
Sincerely,
M.
