How to not get blacklisted, trash/spam moved for sending emails?

How to find my limitations and methods to not get blacklisted, trash/spam moved for sending emails?

I have growing number of like 10000 e-mail adressess and e-mails that I have to send on daily basis regarding:

user registration
reminders
confirmations
news

I want to send mailing to my community but am afraid of beeing blacklisted. It happend few times when years back then was sending mailings from virtual server.

Now I own my dedicated server and want come back to sending lare ammount of e-mails (all sort of reasons listed above).

Solution

Make sure your mailing list is opt-in or provide an easy way for your community members to opt-out.
Provide the opt-in/out link directly in every email message.
Make it highly visible!
Send only to your community members.
Don't annoy them everyday with meaningless crap.
Even being careful and providing opt-in/out for your members you can't force them to use it.
Realize that email clients make it easier to just flag it as spam.
