Feature Comparison

Cosy

Automated Onboarding Sequences

Save countless hours by automating how you welcome new members. You can create up to 10 distinct welcome message sequences that are sent via Direct Message (DM) when someone joins your Slack. These messages can be scheduled to send immediately or on a delay (minutes, hours, or even months later), and they can be sent from you, a team member, or the Cosy bot. Fully customize the messages with the member's name, links, and emojis to make every welcome feel personal and warm, even if you're asleep.

Automated Member Introductions

Grow engagement naturally by helping your members connect. Cosy can automatically introduce opted-in members to each other in a private, three-person DM (the two members and the Cosy bot). You set the frequency—every 1, 2, 3, or 4 weeks—and choose the day and time. Cosy randomly pairs members to enhance serendipity while avoiding recent matches, and you can customize the introductory message template to kickstart conversations effortlessly.

Searchable Member Directory

Help your community members find and learn about each other without ever leaving Slack. Create a custom directory by selecting up to 10 fields for profiles (like text, single-select, or multi-choice). You can then notify all members to fill out their profiles with one click. New joiners get a gentle nudge 24 hours after arriving. Members can search and filter this directory via the Cosy app or a simple /member-directory slash command.

Content Highlights & Moderation

Instantly surface the most valuable conversations and identify posts that need attention. Use simple slash commands to find the top 10 most engaged messages in a specific channel or across all public channels. You can also quickly pull up a list of public messages that have gone unreplied to, allowing you to jump in and re-ignite discussions. This feature helps you recognize contributors and ensure no great question or idea gets lost in the chatter.

Mailopoly

Clean Inbox Functionality

Mailopoly’s Clean Inbox feature ensures that only the most important emails reach your attention. The AI intelligently filters out noise, allowing you to see only relevant messages. This feature works from day one without any setup, meaning you can dive right into an organized inbox without stress.

AI Drafting Assistant

With Mailopoly, you don’t need to worry about crafting the perfect email response. The AI Drafting Assistant automatically writes replies in your unique voice, capturing your style and tone accurately. You receive multiple suggestions to choose from, allowing you to edit or send responses in just seconds.

Task Management Integration

Mailopoly is more than just an email client; it includes a built-in task management system. This feature tracks your personal finances, events, and shipments, providing a full timeline of important activities. You can stay organized with ease, ensuring nothing slips through the cracks amidst your busy schedule.

Instant Unsubscriber

Mailopoly’s Instant Unsubscriber allows you to quickly unsubscribe from unwanted senders with just one click. This feature helps maintain a clutter-free inbox, ensuring that you only receive communications from sources that matter to you.

Use Cases

Cosy

For Onboarding New Customers

If you use a Slack channel for customer support or success, Cosy ensures every new customer feels personally welcomed and guided from day one.

This reduces the manual burden on your team while providing a consistent, high-touch onboarding experience that sets the tone for a great customer relationship.

For Building Internal Team Culture

Strengthen connections within your remote or hybrid company.
