Your first scheduled Slack message in three steps
Install the app
Install the Crowdbird app in your Slack workspace and pick the channel to post to.

Write the text, add up to 10 images and videos and switch off the previews if you need to.

Pick your own time or the next free slot in the queue.
Connect Slack to Crowdbird
You install the Crowdbird app in your Slack workspace and pick the channel to post to along the way. You need the right to install apps in Slack for that. You only enter your Slack password with Slack, never with us.
In Crowdbird, every channel is a connection of its own. If you want to post to a second channel, you connect it as well.
What a Slack message can contain
A message can be up to 40,000 characters and hold up to 10 images and videos. You switch off link and media previews per message when a link shouldn't turn into a big card.
Because the app sends the message, it appears with the sender name Crowdbird. So say who it is from, for example with your first name at the end.
When Slack in Crowdbird is worth it
Slack can schedule its own messages too. Crowdbird helps most when the same announcement should appear in Slack and on your social channels at the same time, such as a launch your team needs to know about before the community asks.
One week across every network
In the social media scheduler you see Slack next to Instagram, LinkedIn and your other connected accounts. One piece of content can run on several networks and still get its own, internal text in Slack.
For many messages at once, use the CSV import with text, time, channel and media link. Each row becomes a draft you review before you schedule it. You read replies in the Slack channel in Slack, Crowdbird has no inbox for it.
Common mistakes when scheduling in Slack
Copying the community post into the internal channel as it is.
