Create Tasks That Actually Get Done.

Legal follow-ups get lost when they're not captured immediately. Mattermail lets you create a fully-detailed Clio task the moment you read an email while the context is still fresh.

Log Time the Moment It Happens.

What Mattermail Does

Every Tool Your Practice
Needs, Inside Gmail.

Legal work lives in your inbox. Mattermail brings Clio's core capabilities directly into Gmail so nothing falls through the cracks.

File Emails to Matters

Select any email or entire thread and save it directly to an open matter in Clio. Choose between threading all emails into a single communication or filing each message individually for granular record-keeping.

Thread mode Individual mode 200+ matters

Attachment Management

All attachments across the thread are detected automatically. Use bulk select or deselect individual files to precisely control what gets uploaded to your matter in Clio no manual downloading required.

Auto-detect Bulk select PDF & DOCX

Time Entry Logging

Log time without leaving the email. Enter duration in natural format (e.g. 1h 30m or 1:30), add a description, and set your hourly rate all synced directly to Clio's time entries for the selected matter.
