Email Monster provides a service to mask your email address online with unlimited forwarding addresses. You can block senders instantly, or aggregate them into a single digest. Alias addresses are created when their first email arrives, so there is no need to setup aliases in advance. At any time, you can login to Email Monster and toggle off senders or aliases to never receive emails from them again. This means that any emails from senders or to aliases that you choose will not be forwarded immediately. One digest email will arrive on a weekly or monthly cycle of your choosing, with all emails sent during that period.
