You can change the subject line customers see for each automated email in Settings > Email Templates.
Change the subject line
In the back office, go to Settings > Email Templates.
In the Email Type dropdown, choose the email, for example Order Shipment.
In Custom Subject, type the new subject line.
Click Save Subject.
Placeholders in the default subject
Some default subjects contain placeholders in curly brackets, such as {0}, {ClubName} or {BrandName}. WithWine replaces these with real details, such as your winery's name or the club's name, when the email is sent. If you delete a placeholder from the subject, that detail won't appear.
