I would like to easily add a new sender to an existing gmail filter rule. For example, suppose I have a complex filter that operates based on a list of several senders. When I receive a newsletter from a new sender, I’d like to be able to easily add this new sender to the existing rule.
For now, I have to copy the sender’s email address, click through the settings options to get to the filter, open the filter and paste the new sender into the list.
How can I streamline this process?
