Please put ERROR Notifications on Red or Highlight them with a noticeable style

Hi

Today when sending an email from within Zoho Crm there was an error while sending the message, BUT since it was not noticeable at all !! we did not see the notification and assumed that the message got sent correctly ...

The customer said he did not received the message,  so, when trying to verify if it was sent , we looked it up at that Lead Page, and it was indeed under Emails sent , and yet the customer did not received anything after many hours... so we sent another email message, now with a CC to one of our email addresses, and once again the message was not received by the customer or us. 

We tried a third time and It turns out that at top of the Send Email Pop up Window there was a unnoticeable notice saying that there was an error connecting with the SMPT server. we only saw this notice because we were looking for an error, otherwise it was pretty much invisible to us at first sight 

So, could you guys please do the following:
1.  highlight Errors like this so that Zoho UI becomes more User friendly!! and...
2.  if there is an error sending a message it is assumed that the message wont appear as SENT
from within the Lead/Account page!!

Here´s a ScreenShot, it is more unnoticeable without the grey bars we used to hide our info ... just black text almost the same size as the Error message.
