Smart Labels
Smart Labels help Filo automatically understand and organize your inbox. Instead of manually sorting, you give Filo short natural-language rules (“prompt emails from my bank” / “password reset codes”), and new emails that match will be tagged for you.
1. Default Labels (always available)
You start with Important, Promotions, and Updates.
These three labels:
Cannot be deleted.
Cannot be renamed.
Can have their prompt (rule) customized to better fit your workflow.
2. Custom Labels (your own)
You can create up to three additional Smart Labels (e.g. Work, OTP, Billing). Each custom label includes:
Name (you can rename later)
Prompt / rule – a short description of what kinds of emails belong here
Optional color – purely visual
If you’ve already created three custom labels, you’ll need to delete one before adding a new one.
3. How auto-tagging works
After you set or edit a prompt, Filo uses it to classify future incoming emails. You can also manually apply labels to any existing email (manual labeling doesn’t change the prompt). An email can have multiple Smart Labels at the same time.
Tips for writing good prompts:
Keep them specific: “invoices from Stripe” or “university application status updates”Avoid long paragraphs (100 characters allowed)—one concise sentence works bestMention senders or keywords if relevant
4. Applying labels to an email (Mobile & Desktop)
Open the email.
Tap/click the Smart Label icon.
Check one or more labels to apply them immediately.
Need a new one? Tap/click + (New Smart Label) inside that panel, fill in the details, and save.
5. Creating or editing from the label list
On Mobile:
Long-press any default label to open a menu:
New Smart Label – create a new custom label (name, rule, color)
Edit – adjust the prompt for the default label
Long-press a custom label and you’ll see:
New Smart Label – create a new custom label (name, rule, color)
Edit – change name, prompt, or color
Delete – remove the label (this does not delete the emails)
On Desktop:
Hover a label in the sidebar to reveal the "..." menu:
New Smart Label – create a custom label
Edit – default: edit prompt only; custom: edit name/prompt/color
Delete – only shown for custom labels
6. Deleting a custom label
Deleting a custom label removes it from the sidebar. Emails keep their content—only the tag disappears. You can recreate a similar label later if needed.
7. Filtering by labels
Click/tap a label in the sidebar to view only emails that currently carry it. Return to All Mail (or your main inbox view) to see everything again.
