As answered by people managing eM Client and ForthWrite.
ForthWrite's answer:
Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API
ForthWrite's answer:
ForthWrite learns your writing style from your actual sent mail, not a generic prompt. Every draft sounds like you wrote it because it was trained on how you actually write. It also auto-drafts replies before you open your inbox, so your email is partially handled before your day starts.
ForthWrite's answer:
Most AI email tools give you a blank box and a "write for me" button. ForthWrite builds a voice profile from your sent history and gets more accurate with every draft you edit or send. Unlike ChatGPT or Gemini, it works natively inside Gmail and Outlook with no copy-paste. Unlike Lavender, it writes the draft, not just scores it.
ForthWrite's answer:
Professionals who send high volumes of relationship-critical email and cannot afford to sound generic: lawyers, financial advisors, recruiters, account executives, consultants, and founders managing their own inbox.
ForthWrite's answer:
Built out of frustration with AI writing tools that produce text that sounds nothing like the person sending it, and as a way to handle large amounts of daily email. The core insight was that your sent mail is the best training data you already have, and no tool was using it.

One point in eM Client’s favor is its free version. However, its features are pretty limited. For example, you can only use it with two email addresses, and the only customer support option is the user forum.
EM Client is a strong competitor of Outlook that has a easy-to-use interface. This application helps you to manage email, calendar, contacts, and tasks. It can be used for Windows and Mac.
I built ForthWrite because I kept sending emails that sounded like they came from the same generic AI as everyone else. After launching it, I still use it for my own inbox every day, which is about the most honest...

Also, if you're also trying to use Xtra email in Microsoft Outlook, also expect problems. Outlook is also crap. There are other email application options. Em Client (emclient.com) is an excellent alternative to Outlook. Source: about 3 years ago
Totally agree on the security risk. On the other hand setting up, maintaining and explaining PGP for non-technical users usually leads to not using encryption at all, which is by far less secure than a self-managed PGP gateway on a... Source: over 4 years ago
