AI Email Writer | HubSpot vs Shortwave

HubSpot's AI Email Writer is an email assistant built into Marketing Hub that drafts marketing campaigns and sales outreach from text prompts. You pick an email template, use slash and highlight commands to generate or rewrite copy, then send and track everything from the same HubSpot CRM dashboard.

Standalone AI writing tools stop at the draft. HubSpot ties generation to your contact database, so personalization tokens pull from CRM records and campaign analytics log open rates and lead submissions automatically. That integration is the trade-off: you get less flexibility than a general-purpose writer, but you skip exporting copy into a separate ESP.

Marketing teams use it for blast campaigns and segmented messaging. Sales reps use it to generate cold outreach drafts at scale and customize tone, length, and spelling with inline commands. The free tier covers basic AI writing with no credit card; Starter, Professional, and Enterprise Marketing Hub plans unlock advanced automation and analytics.

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.
