Huge amount of money and efforts are expended by AOL, Hotmail, Yahoo etc. to intercept junk e-mail (spam) reaching their users and their mail server filters are know to delete email messages with subject lines like: Make money, $$$, FREE, XXX, HomeBase, etc. See: Email Filtering

Many ISP's mail servers are known to blocked or delete emails from some sender email domain due to sending emails repeatedly to non-existing recipients within their domain. Spammers are know to use software that generate random email addresses for spamming and don't bother to remove bounced or undelivered mails, hence, ISPs assumed that the sender is trying to spam. See: Email Rage

See Spam Assassin http://spamassassin.org/tests.html for the point system guideline that determined, if your newsletter meets "standard" imposed by many ISPs mail filters.

Notes: Automatically filter and delete--not bounced, hence, you won't know if your message actually went to the intended recipient. Email message containing certain words and/or exceeding certain size--that matches ISPs filters are considered spam and deleted.

If you are using your own mail server program and your mails got bounced/undeliverable. See: Mail Server FAQs

Keep in mind that AOL doesn't show the FROM: name that you provide, it only shows readers the FROM address, so make sure you are not sending with a typical spam like looking email address like this example: jonessnews_1234@myemaildomain.com
that is as good as telling the recipient or the spam filters "you can delete this mail".

From: name? It is the name that you have enter into your email client ie: Outlook Express, Name: field--(start-up outlook, >Tools, >Accounts, >Properties and at the "User Information" Name: field--that's the From: name that won't show-up for AOL recipients and the FROM address? E-Mail address: field -- That's what will show-up for AOL recipients.
