What is OutMass?

OutMass is a user-friendly browser extension that works with Chrome and Edge, enhancing the Outlook web experience by adding features for mass emailing and mail merging. It allows users to execute campaigns directly within Outlook, ensuring that all messages are sent via their Microsoft accounts using the official Graph API, which helps recipients view them as personalized emails instead of mass correspondence. The extension is compatible with both Microsoft 365 and personal Outlook accounts, making it versatile for different users. Campaigns can be easily launched from a CSV file, with each column representing a merge tag, guaranteeing that each recipient gets a customized message. The tool includes tracking for opens and clicks to monitor recipient engagement, while also performing daily checks for replies to facilitate prompt responses. For emails that go unopened, automated follow-ups are triggered, stopping as soon as a reply comes in. Additional features encompass scheduled sending, daily sending limits, A/B subject line testing, an AI-driven email composer, reusable templates, detailed campaign analytics with CSV exporting options, unsubscribe links, and the option to include OneDrive attachments. With support for 13 languages, this intuitive interface is designed to be accessible to a broad audience. Users can begin with a free plan that permits 250 emails per month, the Starter plan which allows for 2,500 emails at $9/month, and the Pro plan that includes 10,000 emails for $19/month, accommodating different needs and financial situations. Overall, OutMass significantly streamlines the management of email campaigns, ensuring efficiency and effectiveness in communication. This innovative tool opens up new possibilities for users looking to enhance their outreach strategies in a professional manner.
