A first message sent by the pager server has labels for return buttons on the pager, and in response to the subscriber selecting a return button the pager server sends a new pager message with new labels for the return buttons whereby the subscriber may further instruct the pager server. Systems are disclosed for stock transaction alerts wherein a subscriber can reprogram variables at the server, and for e-mail alerts and forwarding, wherein the subscriber can select and alter delivery types, such as voice, fax and so forth, and may also select multiple and alternative destinations for copies of the original message to be forwarded. In some embodiments a subscriber can select and return canned responses to the originator of an e-mail, by pressing appropriate return buttons which the server matches with the canned responses.
