Shortwave
What is Shortwave?
Shortwave is an AI email client built by former Google engineers that wraps Gmail with inbox organization tools and an agent you can prompt to search, write, schedule, and filter mail. It runs on iOS, Android, Mac, and Windows and syncs with Gmail accounts. The app positions itself as a spiritual successor to Google Inbox, with bundles, splits, and keyboard shortcuts at the center of daily triage.
Most Gmail add-ons bolt on one feature. Shortwave treats the whole inbox as a workflow surface: you triage with bundles and todos first, then ask the agent to draft replies, run natural language search across years of mail, or spin up filters written in plain English. That combo of Inbox-style organization plus a prompt-driven assistant sets it apart from Superhuman-style speed clients and basic AI summarizers.
Sales reps, founders, and support leads use it to split high-priority threads, track read receipts, and share live threads with teammates without pasting screenshots into Slack. Teams on Gmail who miss Inbox bundles or want calendar-aware scheduling from inside mail tend to stick with it once they adopt the Shortwave Method triage flow.
Instantly.ai
What is Instantly.ai?
Instantly.ai runs cold email outreach with AI agents that find leads, write copy, and launch campaigns from one workspace. Its Copilot can build a full campaign from a prompt, while AI Workflows route replies, tag visitors, and trigger follow-ups without manual setup.
Most sequencers stop at sending. Instantly bundles unlimited email accounts and warmup, a 450M+ B2B lead database, waterfall enrichment across 5+ providers, and revenue tracking tied to pipeline and conversions rather than open rates alone. The Scale bundle adds an AI Reply Agent and Unibox for managing replies inside the same tool.
Sales teams and agencies use it to scale outbound without juggling separate lead lists, warmup tools, and copywriters. Instantly cites 50,000+ sales teams on the platform and customer stories reporting 100,000+ emails across 20+ domains with 20%+ reply rates.
