About

OutMass is a browser extension for Chrome and Edge that adds mass-email and mail-merge capability to Outlook on the web. Campaigns are built inside Outlook itself, and every message is sent through the user's own Microsoft account via the official Graph API, so recipients see a normal email rather than a bulk sender. Microsoft 365 and personal Outlook accounts are both supported. Campaigns start from a CSV: each column becomes a merge tag, and every recipient gets a personalized message. Open and click tracking show who engaged, and a daily reply check catches responses. Automated follow-ups re-contact non-openers and stop the moment someone replies. Scheduled sending, per-day send limits, A/B subject testing, an AI email writer, reusable templates, campaign reports with CSV export, unsubscribe links and OneDrive-link attachments complete the toolset. The interface is available in 13 languages. Free plan: 250 emails per month. Starter: $9/month for 2,500. Pro: $19/month for 10,000.

About

SendGuard for Outlook is an email security add-in for organizations using Microsoft Outlook and Microsoft 365. It helps reduce misdirected messages and accidental disclosure by prompting senders to verify recipients and attachments, highlighting external addresses, and warning before Reply All. Administrators can configure rules for outgoing messages, including checks for sensitive information and actions that prompt, block, or delay sending; higher-tier plans can scan attachment contents. SendGuard supports message delay and cancellation, branding, and logging of user actions. Windows desktop and Microsoft 365 add-in editions support centralized deployment and administration. The Microsoft 365 add-in is available in New Outlook, Outlook on the web, and Outlook for Mac; Outlook mobile support is also offered. It serves professional services, healthcare, finance, and public-sector teams handling sensitive email.
