Where this came from (Reddit)

People who serve many clients waste time filing email by hand.

The threads (in our words)

Reddit blocks automated reads, so we couldn’t record upvote or comment counts. The business below is our own design inspired by these threads.

Who it’s for

Consultants, accountants and agency owners.

Adapt it to your industry

  • Start with one niche or customer type, then expand.
  • Ask your first 10 customers what they would pay before you build more.
  • Keep a human check on anything sent in a customer’s name.

Step by step

  1. Connect Outlook or Gmail through their official APIs with the user’s consent.
  2. Learn the folder rules from the existing folders.
  3. File new emails by client and flag urgent ones.
  4. Draft replies for approval; nothing sends automatically at first.
  5. Charge monthly by Stripe.
  6. Grow with how-to content and compliant outreach.

Ready-to-copy prompt

Here are my client folders and 5 new emails: [paste]. Say which folder each belongs in, how urgent it is, and draft a short reply where needed.

What they did

An agent reads each email, files it under the right client, and drafts replies for approval. We designed this business from real Reddit threads; it is an idea for you to build, not a description of the posters’ businesses.
