Issues

E-mail Template Limitation

Only the <Table> tag can be used.
Only the inline styles can be used.
Float positioning can not be used.
Style are best written in the corresponding tag, inheritance may be invalid.
Returning newline characters in the E-mail template may result in a lot of <br> tags
