How to cancel Signal Iduna by mail
Start with your account details
Signal Iduna will look your account up from what the letter says, so check the policy number, the name on the policy and the date you want cover to end first.
Prepare the letter
Because Signal Iduna is dealt with in German, the letter is written in German (template de). Subject: “Betreff: Kündigungsanfrage – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 44139 Dortmund. Keep the tracking number it gives you.
Keep proof the letter arrived
The receipt dates your request. Look at your next statement for any Signal Iduna charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Signal Iduna cancellation letter goes
Signal Iduna lists Joseph-Scherer-Straße 3, 44139 Dortmund, Germany as its mailing address.

Cancelling a insurance or protection plan
Insurers cancel by policy and by effective date, so the request has to name the policy number and the date cover should stop, ideally after replacement cover is in place.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
