AI-native Gmail email with a best-in-class AI assistant

Why A-tier?

Shortwave is an AI-native Gmail client whose AI Assistant drafts, summarizes, and searches in natural language, with smart bundling, Ghostwriter drafts, and Tasklet automations, earning A for inbox intelligence and drafting.

SaneBox8.08

AI email filtering that reads headers only, never content

Why A-tier?

A privacy-first triage layer that sorts the inbox by reading headers only, with a 16-year track record and SOC 2. It filters rather than drafts, so generative needs require another tool.

+ Privacy-first, reads only headers and never message content+ Works with any client server-side, no plugins neededRule-based triage, does not draft replies or extract tasksNo permanent free tier, only a 14-day trial
B
Superhuman logo
Superhuman7.96

The fastest keyboard-first email, now with AI drafting

Why B-tier?

Superhuman is the fastest keyboard-first email client, now with Write with AI in your voice, Instant Reply, and Auto Summarize, earning B. Its premium ~$30/mo pricing, individual focus, and AI layered onto a speed client (rather than AI-native) hold it back here.

+ Fastest email; Write with AI, Instant Reply+ Gmail and OutlookPremium ~$30/mo; individual-focusedAI layered on a speed client
Lindy logo
Lindy7.85

No-code AI agents for inbox, scheduling, and workflow automation

Why B-tier?

Lindy manages inbox triage and drafts responses as part of an agent platform, with strong drafting quality. Pricing model and the absence of a free tier are the trade-offs.

+ Inbox management plus AI response drafting in one agent+ 200-plus integrations connect email to wider workflowsCredit pricing is unpredictable at scaleNo permanent free tier
Missive logo
Missive7.62

Email, team chat, and tasks with real-time shared drafts

Why B-tier?

Missive combines email, team chat, and tasks with real-time shared draft collaboration, AI drafting, and rule automation across providers, earning B. It is team-oriented and heavier for solo use, with AI less advanced than Shortwave or Superhuman.
