Classifi

Smart email categorization for Microsoft Outlook

Set rules once. Classifi silently categorizes every email the moment it arrives — by sender, domain, or subject keyword. Your inbox, finally organized.

Rules you set.
Categories that stick.

01

Set your rules

Match emails by exact sender, domain, or subject keyword. Assign one or more Outlook categories to each rule.

02

Classifi learns

Open any email and use the Learn tab to instantly create a rule from what you see — no typing required.

03

Auto-categorize

New emails are categorized the moment they arrive. No manual work, no plugins to babysit.

04

Syncs everywhere

Rules are stored in the cloud. Sign in on any device and your rules are right there waiting.
