What is OutMass?
OutMass brings GMass-style mail merge and mass email to Outlook on the web (Microsoft 365 + Outlook.com): personalized campaigns from a CSV, open/click tracking, reply detection, scheduled sends, automatic follow-ups that stop when someone replies, and A/B testing — all sending through your own Outlook account via Microsoft Graph, so your email never goes through third-party servers. Free up to 250 emails/month; paid plans raise the limit and add scheduling, follow-ups and AI drafting. Available for Chrome and Edge with a 13-language interface.
