I have a content type that I use to maintain a list of clients. One field is an email field, the clients are not users of the site, and they are not subscribed to any newsletter in the site.

How can I send an email to all my clients using the cck email field on content creation to let them know something.

None of the following options seems to work:

I don't want to "Send mail to a user" (the client it's not a user)
I don't want to "Send a mail to all users of a role"
I don't want to "Send a mail to an arbitrary mail address".. Well, I do want this but how can I get the cck email field loaded as the recipient.

I'm not using the cck email field module, the field it's just a text field, but I could use it if that helps.

Thanks in advance

Luis
