Description

Missive is a shared-inbox and team collaboration app that layers internal discussion, task assignment, and shared team spaces on top of email (plus text and other channels) so teams always know who's handling what. It's built for small-to-midsize teams in customer-facing operations — support, sales, real estate, e-commerce, accounting, and professional services — that outgrow forwarding and CC'ing. What most sets it apart is that internal comments, tasks, tags, and statuses live directly inside the emails themselves, and its AI assistant pulls real context from connected tools like Stripe or a CRM via MCP rather than acting as a generic sidebar.

SleekFlow is an omnichannel conversation platform that brings WhatsApp and other messaging channels into one team inbox. It adds AI agents, broadcast campaigns, an automation flow builder and a social CRM for sales, marketing and support teams. Plans are priced per month with included monthly active contacts and user seats. Essential starts at US$49 a month (US$588 billed yearly), Pro is US$109, Premium is US$279 and Enterprise is custom. There is no free plan, but a 7-day free trial of the Pro plan is offered with no credit card required.
