One of the coolest things about Gmail is its filters — set up properly, filters can add loads of functionality to your already-powerful Gmail account. Save time and space, rid your inbox of unwanted emails, and turn your Gmail into a multi-functional tool with simple filters.
There are some limitations to Gmail’s filters that I’d like to see improved in the future, including:
- the inability to mark a post as read
- the inability to create live “smart folders”
- difficulty in adding a large number of email addresses to a filter
But all in all, the filter function is very cool. Here are some ideas for how to use it:
- Killfile. If people send me too much junk mail (jokes, chain mail, etc.), they get added to my killfile. It’s a simple filter that looks at the “from” field and deletes the message if it’s one of the addresses I’ve added to the filter. Every now and then I’ll decide to add someone to my killfile, and I’ll just open up the filter and add their address.
- Booleans. The filter works much like Gmail’s search function, in that you can add search terms such as AND or OR or NOT. So I can look for addresses that are from a number of people (using OR), or emails that must include all of the words on a list (using AND). Use search operator symbols to make it even easier: “|” for OR, space for AND, “-” for NOT, and parentheses to group different terms in your search string.
-
Other search terms. Beyond the common terms above, your filters can use other terms such as “from:”, “to:”, “has:”, “is:”, “filename:”, and “label:”, among others. Using these terms, you can make your filters even more powerful.

Send reminders to someone. One of the things I wish Google would add to Gmail is the ability to send a delayed email. This would allow me to send reminders to someone at regular times. Instead, I sign up for a reminder email service to send reminders (meant for other people) to my gmail address, and then set up filters to forward the reminders to various people depending on the subject or content of the email. It’s not perfect, but it allows me to send reminders to different people on a regular basis.
-
Calendar and log. I set up Google Calendar to send me reminders of events. You can set up a label (“events”) so that your calendar reminders go straight to the label, star the message, and skip the inbox. Now not only are your events in one place, instead of scattered through your inbox, you can unstar the message when you complete the task or event, and now you also have a log of all the things you’ve done.
-
To-dos. This is a commonly used function, but you can email yourself tasks that you need to do, and then set up a filter that has your email address in both the “to” and “from” boxes, that applies the label “to-do” to the message. This will allow you to view all your to-dos in one filter. Or, if you’re a GTD fan, you could set up to-dos for each context (@work, @home, @errands, @phone, etc.), by creating different labels for each, and then setting up filters for different email addresses. Email yourself at yourname+work (you don’t need the @gmail.com part), and set up the filter to label that address “@work”, and so on for each context.
