To double check if you missed anything after customising all email templates in Magento, you can do a File Search on Selected resources (app/locale/(locale_code)/template/email in eclipse with these keywords:
- (555) 555-0123
By the way, eclipse can do Replace on Selected resources, which is an equivalent tool of File & Replace in Folder using Notepad++. I am sure a single linux command can also do the job but I can’t remember the syntax. Let’s just use eclipse, straight forward.
