If these messages are from legitimate subscriptions or from actual credit cards that you had, it’s best to unsubscribe from the mailings. They’re not actually spam, and you wouldn’t want to tell SpamSieve that they are after previously telling it that similar messages were good.
In general, if it seems like certain spams keep getting through, you should see this page. It will help you:
- Determine whether the messages actually got through SpamSieve.
- If so, see why SpamSieve thought they weren’t spam.
- Report information about your setup and your spam so that I can help adjust your setup and/or improve SpamSieve.
