Missive

Missive is a team collaboration platform built around shared inboxes and real-time email co-drafting, rated 4.8/5 on G2 (753 reviews as of 2026, per G2.com) and claiming over 1,000 reviews across platforms (per missiveapp.com). The platform connects email accounts (Gmail, Office 365, IMAP), WhatsApp, Instagram, Messenger, SMS, and a live chat widget into a single workspace. Pricing follows a per-user model: Starter at $14/user/month, Productive at $24/user/month, and Business at $36/user/month — all requiring annual billing for those rates (source: missiveapp.com/pricing, March 2026). A free plan exists with a 3-user cap and 15-day message history.

Converge takes a different approach with flat-rate pricing at $49/month for up to 15 team members. Where Missive focuses on email collaboration with messaging channels added on, Converge is built as a messaging-first support inbox covering WhatsApp, Telegram, Discord, Instagram, Zalo, Messenger, Gmail, email, and an embeddable chat widget with visitor tracking and lead capture. The two products overlap on core messaging channels but diverge on pricing structure, channel coverage, and widget capabilities.

Missive's genuine strength is collaborative email. Multiple team members can edit the same draft simultaneously — a feature rare among inbox tools. The platform also includes team chat, built-in task management, conversation assignment with workload balancing, canned responses, and rules-based automations (available on Productive plan and above). Third-party integrations cover Salesforce, HubSpot, Shopify, GitHub, Retool, and others. AI features work through BYOK (bring your own OpenAI, Claude, or Gemini API key) for drafting assistance and translation. SOC 2 Type II compliance is included on all plans (source: missiveapp.com/pricing).

Missive's limitations show in channel coverage and feature gating. There is no native support for Telegram, Discord, or Zalo — three platforms with a combined user base exceeding 1.3 billion. The Starter plan ($14/user/month) excludes integrations, automation rules, and analytics, which pushes most operational support teams to the Productive tier at $24/user/month. The live chat widget covers basic messaging but lacks visitor identification, UTM tracking, or lead capture before conversations begin.

Converge includes all nine messaging channels at the base $49/month price with no feature gating. AI reply suggestions come built in with configurable tone (professional, friendly, or casual) and automatic quick reply matching — no API key required, though BYOK is also supported. The embeddable chat widget provides visitor tracking with beacon data, UTM attribution, FAQ self-service, CSAT feedback collection, and lead capture. SLA policies with per-priority breach detection and auto-routing (round-robin or load-balanced) are included without requiring a higher pricing tier.

Missive pricing tiers (annual billing rates, per missiveapp.com/pricing, March 2026):

• Free: $0 — up to 3 users, 15-day message history, limited shared accounts
• Starter: $14/user/month — up to 5 users, team email, SMS, social accounts, no integrations or automations
• Productive: $24/user/month — up to 50 users, integrations, rules & automations, basic analytics, API access
• Business: $36/user/month — unlimited users, SAML SSO, IP restrictions, advanced analytics, personalized onboarding

Monthly billing costs roughly 25% more than the annual rates shown above. Cost comparison against Converge ($49/month flat for up to 15 team members, 14-day free trial, no credit card required):
