Why Mustloop exists
“I lost track of my own outreach while looking for users for my last product. I asked Indie Hackers how everyone else managed it. Most people didn't. So I built the tool I needed.”

Questions
No, and there is nothing to maintain. Mustloop builds your list from your forms and Gmail on its own, and only shows you the people who need you.
Never. Every first email, reply and follow-up waits for you to review and send. It goes out from your own Gmail, and when you send from Mustloop you get thirty seconds to take it back.
It looks for conversations that could become business. Email content is read only in the moment, to write a short summary or a draft. Mustloop keeps the summary, not the email, and fetches the original from Gmail when you open it. What Mustloop does with your Gmail →
It learns how you write from your sent mail: your greeting, your length, your tone and your sign off. For each conversation it works from a short AI summary of where things stand and their latest message, so the draft answers what was actually asked.
If they wrote last, it's yours to reply to. If you wrote last and it's been quiet for three days, it's time to follow up. Either way, Mustloop drafts that email for you. Whether a conversation is over stays your call: mark it done and it leaves your list, and if they write again it comes back on its own.
Write down what you know as a note, or log the call or meeting, on the person, their company or the conversation. Mustloop uses it in every summary and draft, so the follow-up picks up where you actually left off. It does not read LinkedIn or other platforms directly.
Not yet. Mustloop works with Gmail today.
Through a webhook or the API, from your server. Point your form tool, your CRM or a Zapier, Make or n8n automation at Mustloop. There is no snippet to paste into your website.
No. Your morning list can come by email. Slack adds alerts with buttons, and replies you can draft and send without leaving it.
The founding plan includes 200 AI drafts a month, in your voice. That covers the first emails, replies and nudges Mustloop writes for you.
New members pay €19 a month. Founding members keep €10 a month for as long as they stay.
