How to Send a Message with Threadly

Step-by-step guide to composing and sending a broadcast with Threadly's message editor: write your message, add images and actions, choose where it goes and who it's from, then preview, test and send.

Sending one message to many channels or people is Threadly's core feature. The message editor has two screens, Message and Destination & Sender, and your work saves as you go, so you can leave and come back from Drafts at any time.

1. Open the editor

In Threadly's Home tab, under Messages, click ✏️ New Message. A new draft named New Message – <today's date> is created.

2. Write your message

Message Content is always open. Type your message here. Slack formatting, emoji, @mentions and links all work.

The other sections are collapsed. Click a section to expand it. A ✓ appears once it's filled in.

Section	What it's for
Message Info	Name (only you and your team see it in Drafts and Analytics) and Preview text (shown in Slack notifications)
Image	Upload an image or paste a public image URL
Actions	🔗 Add CTA, 📝 Add Form or 📅 Add Booking. See Introduction to Actions.
Template	📋 Choose Template to start from one of your templates, a team template or a quick-start template. See How to Create a Template.

Below the message box, ➕ Add Variables lets you personalize with {{user}}, {{channel}} or your own variables. See Leveraging Message Variables.

Click Next: Destination & Sender →.

3. Choose when, where and who

Section	Options
When to Send	⚡ Send Now or 🕐 Schedule (Pro). See Scheduling Messages.
Where to Send	# Channels (up to 75), 👥 Groups (one of your Segments, Pro) or 💬 DMs (up to 75 people)
Who is this from?	Myself or a Custom profile. See Message Settings.
Advanced options	The caption under your message and link previews

If Threadly isn't a member of some of the channels you picked, you'll be offered Add Threadly to All Channels. Learn more.

Direct messages are always sent as yourself, and replies come to you.

4. Review, test and send

Click 👀 Review & Send to open the preview. It shows your message the way recipients will see it, with a To · From summary and the send time. Variables are filled with sample values, and Preview as… shows the message with one real recipient's name.

The preview warns you before you send if:

• the message has no destination or no body

• an action button has an invalid URL, in which case that button won't be sent

• you're sending as yourself to channels you're not a member of. Those sends will fail, so join the channels or use a custom profile.

• you're on the Free plan, in which case a "Sent with Threadly" tag will be added

From the preview's menu you can also:

• ✏️ Edit Message

• 📤 Send Test Message to a channel or person of your choice, with real variable values

• 📋 Save as Template

• 💾 Save for Later, which keeps it in Drafts

• 🗑️ Delete Message

Send it, and Threadly confirms the message is on its way. Follow delivery and engagement in Logs & Analytics.

Tip: Message the same channels often? Save them as a Segment and send to it in one click. Sending the same message on a schedule? Try Workflows.
