Allow customization of Customer Agent verification email (From address + content)

Use case:
When using the Customer Agent with “Verify email” as the data protection level for CRM properties (e.g. AFAS Relatie id), HubSpot sends a verification email to the contact before sharing sensitive data.

Current limitation:
The verification email is system-generated. As admins we cannot:

    • Change the From email address / sending identity
    • Customize the subject or body text of the verification email

Why this matters:

    • For our customers, the verification email looks different from our normal branded emails, which can reduce trust and increase the chance it’s ignored or treated as spam/phishing.
    • We’d like to clearly explain (in our own language and tone) why they’re getting this email and what they should do with it.

Requested improvement:

    1. Allow us to choose the From address (from our verified / connected addresses) for Customer Agent verification emails.
    1. Allow basic customization of:
        • Subject line
        • Intro text/body (e.g. localized message, short explanation)
    1. Ideally, support per-portal branding so the verification email visually matches our other customer communications.

Nice-to-have:

    • Ability to preview a sample verification email in the Customer Agent settings.
    • Support different languages if the portal uses multiple brands/locales.

This would make the verification flow clearer and more trustworthy for end users while keeping the security benefits of “Verify email”.
