The Huge Attachments will then be uploaded to your account and will be sent as a link to the recipient(s) who can access and download the files using it. You can send multiple attachments of up to 1 GB each depending on your account storage and subscription plan.


  • If you want to send the same file via email to a different set of recipients, you needn’t upload the file again. You can select the file from the attachment section under My attachment >> Huge attachments section and send it again. 
  • Huge Attachments is not available with free plan.

File Permissions

You can set access permissions while sending a Huge Attachment. The permissions are:

  • Limited access - Only the recipients can access using their linked Zoho accounts

You can choose the limited access permission when you want to send Huge Attachment to Zoho users or users with linked Zoho accounts. This ensures only those recipients of the email can access/ download the attachment using the link. If the link is accessed without logging in to the respective Zoho account, the file won't be accessible.

  • Public access - Anyone can access using a secure and unique link

When you want to send large files to recipients who may not have Zoho accounts, you can set Public access permission. Upon which, a secure link will be generated for the attachment. The file uploaded can be accessed and downloaded by anyone who has this secure link. 

Edit Permissions

By default, all attachments are set to Limited access. You can change this access level, after attaching it to an email, by clicking on the Limited access option available on the attachment.

Edit permissions for email attachements

You will have the option to make it a Public (accessible by all), in which case anyone with that link can access the attachment. Select Public and click Ok to generate the secure attachment link.
