What you can post
What You Can Schedule on Slack
How connecting works
Install the SolMarrow Slack app and pick the channel on Slack's own screen. There's no password to share: Slack handles the sign-in and the permission, and you can remove the app from your Slack workspace whenever you like.
Text messages
Up to 4,000 characters, enough for a weekly update, a release note or an internal newsletter.
Messages with images and video
Attach up to 10 images and videos to one message, mixed as you like. Videos can be up to 1 GB.
How it works
From Idea to Published Slack Post in Four Steps
- 01
Connect Slack
Install the SolMarrow Slack app and pick the channel on Slack's own screen.
- 02
Write once, tailor it
Write the post, then adjust the text and media for Slack. The preview shows how it will look, and the composer flags anything Slack won't accept.
- 03
Schedule or publish
Pick a date and time in your workspace's time zone, publish right away, or save a draft. SolMarrow posts on time, even when you're offline.
- 04
Keep track
Every published post links back to Slack. If one can't go out, you see the reason and can fix it and try again.

Tips
Slack tips that make every scheduled post work harder.
Grow on Slack
Put the point in the first line
Slack notifications show only the start of a message. Make the first line say what changed or what people need to do.
Use @channel sparingly
Mentions that notify everyone are easy to overuse. Save them for messages that need action today, so people keep paying attention.
Keep a regular slot
A weekly update that lands at the same time every week becomes something people look for instead of something they skim past.
Your Brand
#general
Write for scanning
Short paragraphs, line breaks and simple lists are easier to read in a busy channel than one long block of text.
Think about time zones
For distributed teams, schedule messages for an hour when most people are online, not just when you finish writing them.
