Feature Comparison
Cosy
Automated Onboarding
Create and automate up to 10 distinct welcome DM sequences for new members, sent from you, a team member, or the Cosy bot. Fully customize messages with member names, links, and emojis, and set time delays from immediate to months in the future. This ensures every new member is welcomed personally, even outside business hours, saving hours of manual outreach and follow-up while providing a consistent, warm first impression.

This tool helps members discover each other easily, fostering a more cohesive and supportive community environment.
