Blacklist

A blacklist is a filter that prevents certain e-mail addresses or domains from receiving mails, independently from their subscription/activation state.

When you send a message to a given list, before each mail is actually sent, Sendblaster checks whether the recipent's address or domain is included in the blacklist: if it is, the mail is skipped (an "<address>: blacklisted" message will be shown in the log panel).

Sendblaster supports two different blacklists:

You can enter items as free text; each row must contain one address / domain (and no extra characters: you can't use wildcards). You can copy to / paste from the clipboard, in order to manipulate blacklists with third party software; or press Edit with Notepad button to open a blacklist with Windows' built-in text editor (program execution stops until you finish editing and close Notepad).

Here is an example of a valid addresses blacklist:

and a valid domains blacklist:

The following blacklist is wrong because it includes wildcards ("*") and third level domain names ("www."):

Please note thar blacklists have a size limit, and are not intended as a substitute for "proper" unsubscriptions tasks. As a general rule, they should be used for "emergency" or special tasks only (i.e. when someone explicitly asks not to receive any message from you anymore, not even after a subscription; or when you want to make sure your competitors are not receiving newsletters from you).
