We've seen a lot, of successful Slack communities launch over the years. There is one specific pattern that's emerged I'd like to share with you.
Slack groups whose members download the excellent mobile version of Slack are up to 34% less likely to cancel! Having the Slack app on your members phone means your Slack team goes with them wherever they go.
It's no wonder they are more engaged!
The best way we've seen to accomplish this is to use the free Zapier app here: https://zapier.com/apps/slack/integrations/slack/9558/send-a-slack-new-member-a-direct-message
This app will let you automatically send a welcome message to new members. In this message you can share the benefits of downloading the Slack app for their phone. You can even share the download link with them here: https://slack.com/downloads
