Run your newsletter with an AI coworker
A newsletter should be a distribution engine, not a monthly guilt trip. Duet gathers the week of product updates, customer wins, posts, and metrics, turns them into a tight email in your voice, prepares the broadcast in your provider, and closes the loop with what readers actually clicked after the campaign is sent.
How Duet runs this with review rules.
Connect the sources of truth
Duet reads the places your updates already live: GitHub, Linear, Notion, Slack, blog drafts, product analytics, and the last few newsletters. It builds the raw material without asking someone to paste a recap into a doc.
Pick the angle for the week
Duet clusters the updates into themes and proposes the strongest one: a launch, a customer story, a workflow people can copy, or a behind-the-scenes build note. The email gets a point instead of becoming a changelog.
Draft in your voice and format
Duet writes the subject line, preview text, lede, sections, CTA, and P.S. using your prior sends as the voice reference. It also builds the HTML or Markdown to match your template.
Prepare the campaign for approval
Duet checks the audience, suppressions, bounce history, and segment rules before approval in Resend, Customer.io, Mailchimp, ConvertKit, Loops, or your provider. The dangerous part stays reviewed.
Repurpose the email into social posts
The finished newsletter becomes a LinkedIn post, X thread, short product update, and internal changelog. One clear angle fans out across the channels your customers already read.
Report and improve the next issue
After the campaign is sent, Duet pulls opens, clicks, replies, unsubscribes, and bounces, then tells you what to keep, what to cut, and what topic deserves a deeper follow-up next week.

Common questions about handing this off.
Will Duet send emails without approval?
Not unless you explicitly allow it. A safer setup keeps final send behind approval, while letting Duet gather updates, draft the email, build HTML, check the audience, and prepare the broadcast for review.
Which email platforms does it support?
Duet can connect to email platforms through native skills, APIs, exports, or custom wiring depending on the provider. For Resend, Customer.io, Mailchimp, ConvertKit, Loops, HubSpot, or Markdown-export workflows, scope draft, audience, and send permissions before enabling send.
How does Duet know what happened this week?
It reads the systems where the work happened: commits, PRs, Linear issues, Slack threads, Notion docs, analytics, and support conversations. You get a real update, not a brainstorm from a blank page.
Can it keep our brand template consistent?
Yes. Duet stores the approved template, colors, footer, mobile styles, unsubscribe placement, and CTA pattern. Each new issue starts from the same system instead of being rebuilt by memory.
Can it clean or segment the list?
Yes. Duet can identify bounced, suppressed, inactive, high-engagement, product-user, and newsletter-only segments, then recommend who should receive a broadcast before anyone hits send.
Does it help if we only send once a month?
Yes, but weekly or biweekly works better because the source material is fresher. Duet makes the operating cost low enough that a lean team can send more consistently without turning the newsletter into a part-time job.
