100% free & open source

The agent for audience-fit marketing. Open-source.

Your marketing needs the right audience and the right posts. Loopmark researches who to reach, drafts content that fits, and nurtures leads, on your own stack with your own keys.

No credit card. Bring your own OpenAI key and go.

The marketing agent you run on your own terms.

Grow without sacrificing message quality or team capacity.

Set up your business profile once. Loopmark uses it to write posts, emails, and replies that speak to your target audience, in your language.

Keep customers happy while you scale

Complaints get logged, classified, and answered with empathetic responses before reputation takes a hit.

Right posts for the right audience

Ask for a post, email, or content calendar. AI tailors copy to your audience and publishes live or on a schedule.

Convert interest into leads

Every lead gets scored and nurtured with messages matched to their stage, from first touch to closed deal.

Everything in one marketing agent.

Chat once. Loopmark routes to the right workflow so you stop jumping between tools.

  1. Audience research

    Paste a website URL. Loopmark builds personas, pain points, and messaging angles you can save and reuse.

  2. Social posting

    Draft LinkedIn and X posts that match your audience, then publish now or schedule through Buffer.

  3. Email campaigns

    Generate subjects, bodies, and lists. Send tests, CSV batches, or nurture sequences with Mailgun.

  4. Complaint handling

    Log issues, classify severity, and get empathetic reply drafts ready to send in seconds.

  5. Lead funnel

    Score leads, move stages, and send follow-ups matched to interest, demo, or close.

  6. Content calendar

    See the week at a glance. Auto-posting keeps your queue moving without babysitting it.

Audience research turns a website into personas. You review, save, and use them across posts and campaigns.

Content and email get drafted for the people you actually sell to, not a generic template.

Built for teams that outgrow templates.

Whether you are one person or a small marketing crew, Loopmark keeps audience fit in every message.

Solo marketers
