I have a company that sends an email to deliver photos to my clients on my behalf. When they receive the email saying their photos are ready, it shows a hyperlink to them that says my website at the bottom of the email. I also receive a copy of the email so that I can see what they receive.
In other email clients, the website hyperlink is short and sweet and shows my hyperlink correctly. When I receive it in ZoHo, however, it's a mess. The entire long string of email to website link is shown, and it changes the justification dramatically. It's just not pretty. In the current time, we all like "pretty" email. (MailChimp, Constant Contact, Gmail... etc...)
Between font issues in the WYSIWYG and ugly HTML translation from ZoHo... I'm pretty much leaving ZoHo. Searching these forums only validates the fact that everyone's email is ugly here, and that realistically, ZOHO isn't gonna be fixing it soon, or ever.
