How do I sign up?
Last updated: 2 November 2026 · The MargenOptimierer app is in German. Button and menu names are shown exactly as you see them, with the English meaning in brackets.
You create your account with your email address and a password, and you confirm the address through a link MargenOptimierer emails you. You then create your company and become its owner. The free trial lasts 14 days and starts as soon as MargenOptimierer fetches the first orders from your OTTO account. Costs only arise after that, and only if you've added payment details.
How it works
- On the website, click Kostenlos testen (try for free).
- Enter your name, your email address and your password twice, with at least 8 characters.
- If you have a discount code, enter it in the Rabattcode (discount code) field.
- Tick the box for the AGB (terms and conditions) and the Auftragsverarbeitungsvertrag (data processing agreement) and click Konto anlegen (create account). Tips by email have their own tick box, and you can unsubscribe through the link in each of those emails.
- In the email from MargenOptimierer, click „Adresse bestätigen“ (confirm address).
- Enter your company's name and click Firma anlegen (create company).
If signing up gets stuck
The email doesn't arrive
Check your spam folder first. On the page after signing up, you can request a new email with E-Mail erneut senden (send email again), at the earliest one minute after the last one. If you mistyped the address, click Neu registrieren (register again) there and use the correct address. Nobody can use the account with the wrong address.
The link in the email is no longer valid
If the link has expired or has already been used, a page opens where you enter your email address. With Bestätigungsmail erneut senden (send confirmation email again) you get a new email. If you've already confirmed your account, just sign in.
You were invited
If someone invited you to their company, you don't sign up yourself. Open the link from the invitation and choose a password there. You're then a member of that company and don't create your own.
