You can use one filter to manage messages from a number of different email addresses. Here's how:
- Sign in to Gmail.
- Click Create a filter at the top of any Gmail page.
- Enter each email address in the From: field, separated by OR. Make sure to add parentheses around everything listed in the From: field.
- Enter all other message criteria in the appropriate fields, and click Next Step.
- Check the box next to the action you'd like the messages to take.
- Click Create Filter.
You can create an unlimited number of filters, but only 20 filters can forward to other addresses. Combining filters like this is a great way to maximize your filtered forwarding.
