    @Mixalis Nikitaras Thank you for reaching out to us. As I understand you are looking for option to change the sender e-mail adddress of verification email when user signs up with Azure AD B2C.

    As if now you can only customize banner logo, background color, email signature and nothing else:

    You can also completely customize your email using third party email providers such as SendGrid, Mailjet ( there is no option to achieve this within Azure directly ) have to use these email providers but this requires additional infrastructure and custom policies:

    Custom email verification requires the use of a third-party email provider like Mailjet, SendGrid, or SparkPost, a custom REST API, or any HTTP-based email provider (including your own).

    Mailjet -
    SendGrid -
