Power-Up Your Inbox

The Power Tools Fastmail Deserves

Connect for Fastmail adds native Office previews, AI-powered email sorting and composition, and Salesforce integration — all designed to feel like they were always part of Fastmail.

Workflow Utilities That Feel Native

Office Document Previews

Instant previews for .docx, .xlsx, .pptx, and .rtf — right inside Fastmail. No downloads, no clutter.

Cloud Storage

Save attachments to Google Drive, OneDrive, Box, Dropbox, S3, or Nextcloud. Attach files from your cloud storage directly into new emails — no downloads needed.

Tracking Pixel Blocker

Automatically detects and blocks email tracking pixels. See which senders tried to track you — without them knowing you opened.

Safe Link Preview

Hover to see where a link really goes. Click to follow without tracking. Phishing and malware protection built in.

PGP/S/MIME Indicator

See at a glance if an email is digitally signed or encrypted. Supports PGP and S/MIME — something Fastmail's web client doesn't show.

The Workflow You Deserve

We believe productivity tools should disappear. Connect for Fastmail is designed to be invisible. When you click an Office document, it doesn't open a new tab or trigger a download.

It opens a preview modal that is visually identical to Fastmail's own. Read, check data, and get back to your inbox, seamlessly.
