Overview

M

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.

MxToolbox

MxToolbox is your go-to platform for diagnosing and monitoring email delivery and infrastructure health. You can perform instant lookups for MX records, DNS configurations, and blacklist status to identify why your emails might be landing in spam folders. It simplifies the technical complexity of email protocols like SPF, DKIM, and DMARC by providing clear, actionable reports that show you exactly what needs fixing.

You can also set up automated monitoring to get alerted the moment your domain appears on a blacklist or if your mail server goes offline. This proactive approach helps you protect your brand reputation and ensures your critical communications always reach their destination. Whether you are an IT professional managing multiple domains or a small business owner troubleshooting a single mail server, the platform provides the visibility you need to keep your email systems running smoothly.
