Sending email

One of the most basic functions of an email service is sending emails. Zoho Mail provides rich text format editors for sending properly formatted emails. The recipients of the email can be picked from contacts.

Zoho Mail is explicitly built for businesses and helps with sending business emails and normal correspondences. However, as per the policy, Zoho Mail cannot be used to send mass emails or marketing emails to unknown senders.

Email Composer/ Editor

Click the New Mail button in the left pane, to open the Zoho Mail composer, with Rich Text Formatting options. The composer opens in a tab, where you can draft your email. You can choose the inline editor or the new window option to reply to/forward emails from the Settings. The default settings for the Composer can be customized from the Compose Settings. 

The composer includes the following:

  • From: The From address can be selected from the drop-down which contains the main email address of your account, your email aliases, and the external email addresses configured. The corresponding Display name will also be displayed next to the selected email address. You can also configure an external email address as a From Address
  • To: Specify the direct recipients of the email here. The organization's email addresses will be available from AutoFill. Click the To Label, to open the address book and choose an email address from the address book. 
  • Cc (Carbon Copy): Specify the recipients to whom the email should be copied. When you add an email address in Cc, other recipients will be able to view the addresses. 
  • Bcc: (Blind Carbon Copy): Specify the recipients to whom the email should be copied, without exposing the email addresses to others. The other recipients will not know about the email addresses in Bcc. 
  • Subject: Title or a Short Summary of the contents of the email 

Mail Content - Richly Formatted Mail

Zoho Mail provides a WYSIWYG (What You See Is What You Get) editor, which provides options to send a richly formatted email with images, tables, hyperlinks, and even smileys. The formatting options allow you to personalize the layout and your email. The built-in Spell-checker helps you to perform a spell check in your outgoing emails, across multiple languages. You can choose the encoding for the outgoing email. It is recommended that you use UTF-8 for outgoing emails, as it is capable of encoding all characters in Unicode.

Voice Recording

Audio messages are a step ahead of text messages and it adds a personal touch to the recipients. Gone are the days when you had to record audio on your computer and then attach it to an email. Zoho Mail's Record audio feature in the Compose mail window allows users to send voice messages with ease. Follow these steps to send a voice message as an attachment:

  1. Log in to Zoho Mail.
  2. Select New Mail, click the Record audio button from the compose mail window and follow the on-screen instructions.
  3. If necessary, you can Pause the recording in between and continue from where you left off.
  4. Once you are done, click the Stop button to complete the audio.
  5. Click Attach recording, Rename the file to your preference and hit the Send button. Recipients can listen to the audio directly from the web browser by clicking on the Play button.
    record audio attachment


Users can see the recording size at the time of recording the audio and after attaching it. However, below are a few points to remember when you record voice messages:

  • The maximum permissible attachment size depends on the settings configured by your administrator.
  • A minimum of 2MB is required before you can record an audio message.
  • The audio size cannot be 0KB even if the message is too short.

Plain Text Mail

A plain text email is one that contains only the content of the email, without any formatting such as Bold, Italics etc. You can choose the Plain Text option to send an email without any formatting. Click the drop-down in the right corner of the composer, and choose Plain text mode.

Sending email with plain text

The system will request confirmation for converting Rich Text to Plain text. On confirming, the formatting toolbar will be hidden and you will see only the spell check icon. Any formatting changes made to the content and signatures will be lost along with any media or table inserted. These formatting changes will also be reflected when you save the email as a draft or template. Hence, the message will be sent as a plain text email.

To revert to the Rich Text mode, click the same drop-down and choose Rich Text mode. Now you will be able to format the text that you've inserted, add tables, images etc. Even if you revert to Rich Text Mode, the prior formatting will not be restored.

Enhanced Spell check and Composer language

Zoho Mail has an inbuilt enhanced spell checker to correct your spelling and grammar errors on the go. After composing your email, click the Spell check icon. The misspelled words or grammar errors in your email content will be highlighted. Click the highlighted words to see a list of possible words with the nearest spelling or alternative words. You can also add a word to your custom dictionary by clicking the Add to dictionary icon so that it doesn't get flagged the next time you spell-check an email.

Email spell check

If you click the drop-down next to the Spell check icon, you will be shown a list of languages that you can choose from. This primarily means the language against which your email content will be checked for validation during a spell check. It does not refer to the language you can compose the email in. For example, if you've chosen English (US) from the composer language listing, the email content will be checked with an American English dictionary, and relevant spelling and grammar suggestions will be provided.

The language your email is composed in depends on the keyboard you use, and not on any of Zoho Mail's settings.


The Auto-spell check option can also be enabled in settings. You can use this to check your spelling as you type. To enable this option, navigate to Settings > Compose > Spellcheck option. Select the Spellcheck as you type check-box.

The auto-spell check option is available only to users who have subscribed to one of our paid plans.
