What is Inbox Categorization?
Mixmax's Inbox Categorization automatically organizes your emails so you can easily find customer replies, meeting invites, and critical updates—without getting lost in noise. Inbox Categorization is part of Inbox Copilot. It sorts your emails into smart categories, helping you:
Prioritize important messages (like customer replies and meeting invites).
Reduce inbox overload by filtering out marketing blasts and notifications.
Save time by letting Mixmax handle manual triage.
Why use Inbox Categorization?
Stay focused on revenue-driving conversations.
Cut through the noise of marketing emails and notifications.
Save time with an inbox that organizes itself.
Inbox Categorization keeps your inbox sharp so you can focus on what matters most: building relationships and closing deals.
How it works
Once you turn on Inbox Categorization, your inbox stays dynamic — not static. Mixmax automatically updates each email's category as conversations evolve, so you always know what needs your attention.
Emails are automatically categorized into labels.
Inbox behavior adapts as conversations progress:
Todo → Awaiting Reply
When you receive a new message that needs a response, Mixmax marks it as Todo.
Once you reply, the email automatically shifts to Awaiting Reply, meaning you've done your part and are waiting for the other person to respond.
Awaiting Reply → Todo (if they reply)
When your recipient replies, Mixmax recognizes the new message and moves it back to Todo, signaling it's your turn to act again.
Todo / Awaiting Reply → Done
If the conversation naturally wraps up — for example, both sides stop replying — Mixmax marks the thread as Done.
This keeps your inbox clean and focused on active conversations while still letting you find older threads easily.
Reminders can restart the flow
If you've set a manual reminder on an email, it will appear under Reminder until it's time to follow up.
When the reminder triggers, Mixmax automatically moves that message into Todo, so it reappears on your radar.
Noise categories like Marketing are hidden by default to keep your inbox clean. Cold emails stay in your inbox by default and show a banner that explains how to change your settings.
You stay in control: Turn categorization on or off anytime in settings.
Categories
Here's how your inbox is organized:
Todo - Emails you need to respond to (e.g., customer replies).
Awaiting Reply - Messages you've sent that are waiting for a response.
Done - Threads that no longer require action.
Reminder - Emails with manual reminders set in Mixmax.
Sidechat - Internal Mixmax Sidechat threads.
Notification – Alerts from tools like Notion, Jira, or Salesforce.
Marketing+ Cold Email - Newsletters, promotions, or outreach. Marketing emails are hidden by default, while cold emails stay in your inbox.
FYI - Informational emails that require no action.
Internal - Emails from people in your organization.
Sequence – Emails sent via Mixmax Sequences (may also appear in Todo if recipients reply).
How to enable or disable Inbox Categorization?
New accounts start with Inbox Categorization turned off. To turn it on or off, go to My Settings > Inbox Copilot. On the same page, you can also choose whether emails stay in your inbox or move out of it.
Turning off Inbox Categorization doesn't remove the Gmail labels. To remove them entirely from your inbox, delete the labels manually. See how to delete labels in Gmail.
FAQs
I deleted the Mixmax label in Gmail, but it keeps coming back. How do I stop it?
Deleting a label in Gmail won't stop it. Mixmax automatically reapplies its categories as new mail arrives, so labels like Marketing reappear. To remove the Mixmax labels entirely, first turn off Inbox Categorization in My Settings > Inbox Copilot, then delete the labels.
Does it work on mobile?
Yes! Labels sync via Gmail, so you'll see categories on both web and mobile.
Can one email have multiple labels?
Yes, but Mixmax minimizes overlap whenever possible.
Why do some emails show a cold email banner?
Mixmax adds a banner to emails labeled as cold email to show you how to change your settings. Cold emails stay in your inbox by default. If you'd rather move them out of your inbox, go to My Settings > Inbox Copilot.
What happens with manual reminders?
They appear under the Reminder label and shift into Todo when it's time to follow up.
Does Inbox Copilot also label emails I send with other outreach tools?
Yes. Inbox Copilot works across your whole connected Gmail account, not only on emails sent with Mixmax. Emails sent by other outreach tools get the same labels as emails you send yourself. Only emails sent from Mixmax Sequences get the Sequence label. Smart Follow-ups may also remind you to follow up on these emails. See the Smart Follow-Up FAQ for your options.
