Cosy

Automated Onboarding Sequences

Create and automate up to 10 distinct welcome DM sequences to greet new members, triggered the moment they join your Slack. Fully customize messages with member names, links, and emojis, and schedule them to send immediately or on a delay of minutes, hours, or even months. This ensures every new member feels personally welcomed, even outside of business hours, saving you countless hours of manual outreach and follow-up while ensuring no one slips through the cracks.

Member Introductions & Connections

Grow engagement by automatically introducing opted-in community members to each other via direct messages on a regular cadence you set. Introductions happen in a 3-person DM with the Cosy bot, and you can customize the intro message, frequency (every 1-4 weeks), and timing. This feature fosters serendipitous connections, randomly matching members while avoiding recent matches, to build a highly engaged network where relationships form on autopilot.

Searchable Member Directory

Build a rich, searchable directory of all your community members without anyone ever leaving Slack. Create custom profile fields for members to fill out, then notify everyone to build their profiles. Members can search by keywords and filter for completed profiles using a slash command or the Cosy app. This transforms your Slack into a powerful networking hub, helping members find the right people and resources effortlessly.

Content Highlights & Moderation

Instantly surface the most valuable conversations and identify potential issues with powerful slash commands. Discover the top 10 most engaged posts in a specific channel or across all public channels. Alternatively, quickly find all public messages that have gone unreplied to, allowing you to jump in and re-engage the discussion or spot members who may need support, ensuring your community's content remains vibrant and inclusive.

By setting up automated onboarding DMs, you ensure consistent, warm first impressions that scale effortlessly with your growth, freeing you to focus on strategy and content instead of manual greetings.

By systematically connecting members and surfacing past high-value conversations, you create new discussion points and relationships, moving the community from a passive information channel back to an active, engaging hub.

Building a Professional Network within a Company or Group

For internal teams or professional groups, the searchable Member Directory turns Slack into a powerful internal knowledge and networking platform. Members can easily find colleagues with specific skills, interests, or experience, fostering cross-functional collaboration and making the collective expertise of the community transparent and accessible.

Proactive Community Health Monitoring

Community managers can use the content highlight and unreplied message features to proactively monitor the health of the community. Quickly identifying highly engaged content allows you to recognize and reward active contributors, while spotting unreplied messages helps you intervene to support isolated members or spark conversation in dormant threads, maintaining a positive and inclusive environment.

How does the automated onboarding work?

When a new member joins your Slack workspace, Cosy can automatically send them a sequence of up to 10 welcome direct messages.
