 Print Email

The printable format of the email will open in a new window. Click Print again to print the email. 


 Save Email 

You can save the email for future reference in HTML or EML format. While reading your email, click the More Options drop-down, select Save as and choose the preferred format to save the email.

If you save the email in the HTML format, only the content of the email will be saved. In this case, if you want the sender/ subject details, use the export option from the Settings. However, if the email is saved in the EML format the whole message will be saved including attachments.

 Distorted or Garbled Messages

When you receive an email, the email content has the 'encoding' details using which the email will be decoded and displayed in Zoho Mail in a readable format. UTF-8 encoding is adopted as universal encoding and can be used to display multiple languages across browsers, and without any issues in the readability of emails.  

In some cases, the email content may have certain character codes, that are not supported in the 'encoding' details provided in the email. Hence such content may appear Garbled when viewing the message. This often occurs when you have a chain of emails in the same thread, with different character encoding values. 

You can use the 'View Garbled Message' Option, to open the particular email in a new window, and choose a suitable encoding from the browser. 

  1. Open the email which appears to be garbled.
  2. Select Garbled Message? from the More Options drop down.
  3. The message will open in a new browser window. 
  4. Select Encoding from the View menu in the browser toolbar.
  5. From the list, select an encoding appropriate for the language in which you think that this message is written.
  6. The message would display properly on selecting the correct encoding.
  7. If you still have issues in the display of the email, contact Zoho Mail Support with your email headers.


Different browsers have different menu name or items for encoding. Internet Explorer displays the item as 'Character Encoding', Safari displays it as 'Text Encoding' etc. Select the appropriate item as per the browser you use.
