Tell Marsen who you want to reach.

It finds the right people, writes emails and texts in your voice, sends them from your own address and follows up until they reply. Campaigns for founders, small shops and creators, without a marketing team.

From one sentence to a campaign that runs itself

You describe the people and the goal. Marsen does the legwork and shows you everything before anything is sent.

  1. 1

    Say who and why

    “New subscribers.” “Customers who haven’t ordered since spring.” “Dentists in Austin.” In plain words.

  2. 2

    Marsen finds them

    From your contacts, a list you import, your signup form, or research on the web for new leads.

  3. 3

    Review the emails

    Written from your website and brand notes so they sound like you. Change any word, or ask for shorter.

  4. 4

    Send and follow up

    It goes out on schedule, follows up with people who don’t answer, and stops the moment someone replies.

Replies

Every reply, sorted by what people want

Marsen reads the answers and tells you who’s interested, who asked a question and who said not now, with a suggested reply you can send in one click.

In your AI assistant

Ask from Claude or ChatGPT

Connect Marsen once and ask from the chat you already use: how a campaign did, who to reach next, two weeks of posts for a launch. Marsen does the work in your account and hands back drafts to review.

Two people: Sam at Cascade Cycle Works wants pricing for 50 bottles, and Priya at Alder Street asked about custom colors. I drafted answers for both; want me to send Sam’s?
