Overview

Missive

Missive is a collaborative email and chat platform designed to help your team manage communication without jumping between different apps. You can manage shared inboxes for email, SMS, WhatsApp, and social media while chatting with teammates right inside the same interface. This eliminates the need for internal forward chains and BCCs, as you can discuss specific messages in side-chats and co-author replies in real-time.

The software is built for teams of all sizes, from small startups to large support organizations, who need to coordinate on high volumes of external communication. You can automate your workflows with rules, use canned responses for faster replies, and integrate your favorite CRM or project management tools directly into your inbox to keep your data synchronized.

Spark Mail

Spark is an intelligent email client that helps you reclaim your inbox by automatically prioritizing important messages. Instead of wading through newsletters and notifications, you see emails from real people first. You can manage multiple accounts from different providers in one unified space, using a Smart Inbox that categorizes incoming mail so you can focus on what matters most.

You can collaborate with your team by drafting emails together in real-time or discussing specific threads in private side-chats. The platform includes a built-in AI assistant to help you draft, rephrase, and proofread replies instantly. Whether you are an individual looking for a cleaner inbox or a team needing better coordination, Spark provides the tools to handle high email volumes without the usual stress.
