Hi,

Go to Settings > Technical > Email > Templates.

Search and open the email template used for subscription or recurring invoice emails.

In the Subject field, replace ${....} with {{....}} for proper rendering.

Example: use {{ format_date(object.create_date, 'MMMM') }} instead of ${....}.

In the Body (HTML) section, do not use {{...}} or ${...}.

Instead, use QWeb syntax like <t t-out="object.partner_id.name"/>.

Replace all dynamic fields in the body using <t t-out="..."/>.

Save the email template after making these changes.

Send a test email or preview to confirm the correct output.

The email will now show the actual values (like customer name and date) instead of raw template code.

Hope it helps.
