Ellie vs Seventh Sense

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.

Seventh Sense is an email performance layer for HubSpot and Marketo that schedules each message to the individual contact's best open time. It connects to your existing marketing automation stack and adds send-time optimization, audience recycling, campaign orchestration caps, and deliverability insights without replacing your ESP.

Most send-time tools pick one window for the whole list. Seventh Sense profiles each contact, suppresses worn-out subscribers, and coordinates sends across campaigns so you stop colliding with your own emails. The Business plan includes all four AI capabilities, unlimited users, and engagement profiles written back to HubSpot CRM records.

Seventh Sense has served HubSpot and Marketo customers since 2014 and reports 500M+ personalized emails orchestrated monthly. Marketing teams at financial, energy, consulting, and pharma brands use it when batch-and-blast fatigue is hurting inbox placement.
