AI Email Writer | HubSpot vs Ellie

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.

Ellie drafts email replies in your voice inside Gmail or Outlook before you hit send. Connect your inbox and wake up to responses already sitting in your Drafts folder, written in the thread context and matched to your tone. You review every message before it goes out; Ellie never sends on its own.

Most email assistants generate generic text you still have to rewrite. Ellie trains on up to 200 of your sent emails on the Casual plan (1,000 on Business) and pulls from a knowledge base you upload so replies cite your actual policies and CRM data. Business and Professional plans add background auto-drafting and auto-categorization, while Casual users trigger replies manually through a browser extension in Gmail, Outlook web, or Fastmail.

Support teams, founders, and sales reps drowning in inbox volume use Ellie to clear reply backlogs. Plans range from $19 per month for 25 daily replies to $79 per month for unlimited replies and up to 3 connected accounts per user. A 7-day free trial requires no credit card, and Microsoft 365 customers can buy through AppSource.
