Answer every TikTok customer message from one shared inbox.

MIRN connects your TikTok Business account to a team inbox, so your support and sales staff can reply to customer direct messages, assign conversations and track response times without sharing a single phone.

Built for customer conversations

MIRN handles messages that customers send to your TikTok Business account. You reply inside TikTok's messaging rules — we never send unsolicited messages.

Shared team inbox

Every DM sent to your connected TikTok Business account appears in one place your whole team can work from.

Assign & collaborate

Assign conversations to teammates, leave internal notes and mark threads as resolved.

Saved replies

Answer common questions about shipping, sizing and returns in one click.

Auto-reply when offline

Set a greeting or after-hours message so customers know when to expect an answer.

Response-time reporting

See first-response time, open conversations and volume per day.

Respects the 48-hour window

MIRN shows how long you have left to reply and blocks sends outside TikTok's messaging window.

How it works

Set-up takes about two minutes and requires a TikTok Business account.

Create a MIRN workspace

Sign up with your work email and invite your team.

Connect TikTok

Click “Connect TikTok” and authorize MIRN on TikTok's own consent screen. We never see your password.

Reply to customers

New DMs from customers arrive in your inbox in real time. Reply, assign or resolve.

Disconnect anytime

Remove access from MIRN settings or from TikTok. We delete your message data within 30 days.

What MIRN does not do: MIRN cannot start conversations with TikTok users, send bulk or broadcast messages, or access personal (non-business) TikTok accounts. Businesses can only reply to customers who message them first, in line with TikTok's Business Messaging policies.
