# How to Add a User to Threadly

Anyone in your Slack workspace can use Threadly. On Pro, admins give people Pro features by assigning seats in Settings → Manage Pro Seats.

Anyone in your Slack workspace can open Threadly and start sending, with no invite needed. They just [open the app and authorize their account](/threadly/getting-started/accessing-threadly-in-slack.md).

On **Pro**, each person also needs a **Pro seat** to use Pro features like Segments, Workflows, Forms, scheduling, meeting booking and integrations.

## Assign a Pro seat (admins)

1. In Threadly, go to **Settings → Manage Pro Seats**.
2. Under **Available Team Members**, find the person. Use **Search & Filter** to search by name or email, job title or timezone. Partial matches work, so "eng" finds "Engineer".
3. Click **Assign Seat**.

The person gets a DM letting them know. The top of the screen shows your **Active Seats** and **Monthly Cost**.

## Remove a seat

Under **Users with Seats**, click **Remove Seat** and confirm. The person loses Pro access immediately, and the billing change applies at the end of your billing cycle.

## Request a seat (everyone else)

If your team is on Pro but you don't have a seat, you'll see **Pro Seat Required** on the Home tab or when you open a Pro feature. Click **Request Seat**. Your admins get a DM with an **Assign Seat** button.
