threadly new features spring 2025 slack broadcast workflows

Threadly has always helped you broadcast better messages on Slack — from DMs to blasts, partner updates to onboarding workflows.

Now, we’re taking it 8 steps further.

We just launched 8 powerful new features designed to help you automate Slack workflows, personalize communication at scale, and integrate with your tools (like Notion) to reduce busywork and increase results.

Whether you're onboarding customers, broadcasting updates, or sharing content across teams, Threadly now gives you more control, power, and flexibility than ever before.

Let’s dive into what’s new.👇

Powerful Features: 

⚙️ 1. Workflows: Automate Messages with Triggers

You can now trigger Slack messages automatically based on:

  • A new channel created that matches criteria
  • A user joining a specific channel
  • A scheduled time or day (e.g. Fridays at 4pm)

Use this to automate onboarding, send recurring reminders, or keep partners or customers updated — no manual effort needed.

🧠 Pro Tip: Mix and match workflows with custom actions and forms for interactive flows. Learn more about Workflows.

👤 2. Send Messages as a Real User (Not a Bot)

Now you can choose to send Slack messages from your actual profile, not through a Slack bot.

Why it matters:

  • Messages feel personal and human, using your profile icon and name
  • Replies go directly to your DM inbox
  • Engagement goes up

Great for sales, support, and success teams who want to connect 1:1 at scale, but en-masse.

📘 3. Notion Integration: Smart Links to Internal Docs

We've added native support for Notion Buttons in Slack messages.

Now, when you send a message, you can add a contextual button that links directly to:

  • An onboarding checklist
  • A partner enablement doc
  • Internal SOPs and guides

We analyzed 100s of customer workflows to build this — so it’s fast, intuitive, and ready to use.

🧩 4. Variables: Personalized Messaging at Scale

You can now insert smart variables into messages like:

  • {{channel}} – “Hey #new-customer!”
  • {{sender}} – “Hey, it's Jake!”

It’s like mail merge for Slack. Use it for onboarding, team intros, reminders, and more. And, with automated messages (read: Workflows), it'll sound natural without you even trying.

🎨 5. Message Format Customization

Want your action buttons above the image?

Now you can customize the layout of every message you send.
Make your Slack messages more scannable, more readable, and more likely to get clicked.

⚡ 6. Improved /sendmessage Shortcut

No need to open the app — just type /sendmessage in Slack.

Our upgraded command supports faster selection of destinations, faster speed, and fewer clicks.
It’s the quickest way to send a Slack broadcast.

🏷️ 7. Custom Sender Tagline

You can now choose how your message appears, tagline-wise:

  • "Sent by Jacob"
  • "Sent by Threadly"

Control the tone and branding depending on whether you're talking to internal teams, partners, or customers.

🐞 8. Bug Screens: Better Error Reporting

Hit a config error or misfire a message? Threadly now shows why, with clear, actionable messages right inside Slack.

No more guessing. Fix faster, send smarter.

Why It Matters

If you're using Slack to communicate with customers, partners, or internal teams — these updates help you:

  • Automate outreach with Slack workflows
  • Scale personalized messages without lifting a finger
  • Broadcast across many channels and DMs instantly
  • Guide users to the right actions using CTAs and forms
  • Deep-link to Notion, docs, and resources from inside Slack
  • Track performance with clicks, reactions, and views

Threadly is now the most powerful way to turn Slack into a communication engine — one that automates, personalizes, and drives engagement without making you do more work.
