Still receiving email from the Motley Fool mailing lists, even though you know you had unsubscribed? Here’s how to unsubscribe from Motley Fool.

If you sell products online, and if you have a mailing list, you may find that you want to add products to your Paypal account for your mailing list API (such as the Aweber API) to use. For example, when you hook the Aweber API into Paypal, you can choose which mailing list the buyer of a given product gets signed up for by which product they have purchased.

Now that Yahoo and AOL are both stating through the DMARC p=reject that any email coming from a yahoo or aol address that isn’t sent from a yahoo or aol server should be rejected (bounced), problems are cropping up for Hotmail, Outlook, Live.com and MSN users, who are finding their own email addresses being removed from mailing lists for no apparent reason. But there is a reason.

If you use a Yahoo email address, or are on a Yahoo mailing list, then you may already know that recently Yahoo essentially broke countless mailing lists, and generally made a lot of email broken, as any email with a “from Yahoo” address that wasn’t sent through a Yahoo mail server was rejected.

Imagine our surprise to discover that such a large, established organization as Priceline has omitted a little thing like an unsubscribe link from some of their mailings. The main Federal anti-spam law, CAN-SPAM, requires that, among other things, when a business puts you on their mailing list, they must include a link allowing you to easily opt-out, in every mailing. Priceline, however, provides no unsubscribe link, at least in some of their mailings. While we are sure that this is just an oversight on Priceline’s part, it nonetheless can be very frustrating for the Priceline mailing recipient who wishes to opt out of Priceline’s mailings.
