# Common Questions

Answers to common Threadly questions about seats, branding, limits, replies, Slack Connect, editing sent messages and more.

**Who needs a paid seat?**\
Only people who send messages and use Pro features. Recipients, people who click or react, and people who only view analytics are always free. See [How Threadly Charges for Seats](/threadly/admin-and-billing/how-threadly-charges-for-active-users.md).

**Can recipients tell a message came from Threadly?**\
On the Free plan, messages include a small "Sent with Threadly" tag. On Pro there's no Threadly branding.

**How many channels can I send to at once?**\
Up to 75 channels or 75 DMs per message when you pick them by hand. Static Segments hold up to 75 channels, and Dynamic Segments have no limit.

**Why can't I see a teammate's message details?**\
Message logs are private to the sender. Click **Request Access** and they can approve it. See [Message Privacy Settings](/threadly/sending-messages/message-privacy.md).

**Do replies come to me?**\
If you sent as **Myself**, yes. If you sent with a custom profile, replies go to Threadly's bot, and they're still counted in analytics. See [How Threadly Sends Your Messages](/threadly/faqs/how-threadly-sends-your-messages.md).

**Can I send to Slack Connect (shared) channels?**\
Yes, as long as Threadly is in the channel. Dynamic Segments can filter on **Is Externally Shared**.

**Can I edit a message after it's sent?**\
No. Use **Clone message** in the message's analytics to send a corrected version.

**Where did Groups go?**\
They're now called **Segments**. Same feature, new name. See [Segments Overview](/threadly/groups/conversation-groups-overview.md).

**How often do Dynamic Segments update?**\
Every 3 hours, or right away when you click **Refresh Data**.

**Can I cancel a scheduled message?**\
Email <support@trythreadly.com> with the message name, and we'll cancel it for you.
