About

ForthWrite is an AI email writer that drafts replies in your voice, right inside Gmail and Outlook. Open any thread, and your reply is already sitting there, sounding more like you with every email you send. Instead of producing a generic “professional tone” reply, ForthWrite learns from your real sent emails, capturing tone, sentence rhythm, sign-offs, terminology, and the edits you make over time. Click Generate Draft, get a polished reply in your voice, edit if needed, and send; every accepted draft and sent reply becomes part of a private writing profile unique to you. ForthWrite is built for people who care how their email reads, especially when messages need to feel personal, precise, and not templated. It works inside Gmail and Outlook Web, supports both work and personal inboxes, and lets users keep drafting without switching tabs or copying prompts into a separate AI tool.

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.
