Prevent the email from being changed in the profile update form

  1. I want to give the subscriber the option to update his preferences, but not his E-Mail-Address
  2. I am forced to use E-Mail (or SMS) as a mandatory field
  3. I can’t select if I don’t want this field to be editable.

As this would mean chaos in our CRM… is there a way in Brevo to change this behaviour somehow?
