Features
One engine for every channel you post on
Contact Concert collects what you publish, writes the newsletter, sends it, and shows you what worked.
Sources
Connect once. We keep watching.
Contact Concert checks your sources every hour and saves anything new for your next issue.
- YouTube: paste your channel URL or @handle and new uploads come in automatically
- Podcasts: any podcast RSS feed, with episode art
- Substack, Medium, WordPress and any blog or RSS/Atom feed
- X, TikTok, Instagram, Facebook: paste a post link and we fetch its title, text and thumbnail. You can also connect an RSS bridge for a hands-free feed
- Only fresh content goes out: every item is used once, so nothing repeats
AI writer
Sounds like you, not like a robot.
Describe your voice once. Every issue gets a personal intro, a hook for every post and a sign-off that invites replies. Nothing is made up: the writer only uses what you published.
- Three subject lines per issue, plus a preview line
- Sections ordered by what your fans will care about most
- Edit anything before it goes out, or leave it as is
- Your brand color, avatar and sign-off on every email
- Runs on Cloudflare Workers AI. Your content is never used to train models
Autopilot
Set your schedule and forget it.
Choose weekly, every two weeks, or each time you post something new. Pick the day and hour in your own time zone.
- Review mode: we draft and email you, you approve with one click
- Autopilot mode: drafts go straight to your fans on schedule
- Skips automatically if there is nothing new
- Sends one by one, so every subscriber gets a personal unsubscribe link
