Wie fügt man den Link zum Abbestellen in eine E-Mail ein?

The unsubscribe link depends on the service that you use to send emails (such as UniSender, SendPulse, Mailchimp, etc.). Usually such services automatically include an unsubscribe link or allow you to insert a special tag, for example: {{unsubscribe}}, %UNSUBSCRIBE_LINK%, etc.

Bitte klären Sie im Support Ihres Newsletter-Dienstes, wie genau der Link aussehen soll.

If you are creating the email on the Tilda side, you can try using the link: {{UnsubscribeUrl}} - if your mail service supports it.
