What Gets Created in Asana

Casso extracts everything from your email automatically.

Email threads parsed into separate comments (native Asana dumps as one blob)
AI extracts due dates from "need by Friday" (native has no AI extraction)
Full thread history preserved (Gmail add-on only syncs last 5 messages)
HTML formatting preserved (native converts to plain text)
ticket:xxxx in subject routes to existing task (native can't do this)
Works with any Asana plan

Three Ways to Use Casso

Choose the workflow that fits how you work with Asana.

Just Forward It

Got an email? Forward it. That's it. I do this one a lot.

Forward → Asana task created

The Sneaky One

BCC means they can't see it. I learned that the hard way.

BCC Casso → Task logged invisibly

The Fancy One

This one does everything automatically. I barely have to think. Which is good.

ticket:xxxx → Updates existing task

Frequently Asked Questions

Common questions about connecting Outlook to Asana.

Does this work with Outlook desktop and web?

Yes. Casso works with any email client that can forward emails - Outlook desktop app, Outlook web (outlook.com), Outlook mobile, and Microsoft 365. Just forward to your Casso address.

Can I BCC Casso from Outlook?

Yes. BCC your Casso address when sending emails to log them without the recipient knowing. Forward their replies with ticket:xxxx in the subject to update the task.

What happens to attachments?

Attachments are automatically synced to your Asana task. Each attachment is tied to the specific message it came from, so you always have context.

How do replies get routed to existing tasks?

Include ticket:xxxx in the subject line when forwarding. Casso routes the email as a new comment on the existing task instead of creating a duplicate.

How is this different from Asana's native email integration?

Native Asana dumps your email as one blob and only syncs the last 5 messages. Casso parses entire threads into separate comments, extracts due dates from natural language, and preserves HTML formatting.
