Conditions and Actions

Any custom filter has two parts: Conditions and Actions. In simpler terms, you define the conditions in the first part and provide a rule or an action, which should be carried out when the part 1 condition is fulfilled. 


You can set up multiple conditions and multiple actions based on your requirements. The conditions that can be associated with any filter, the operating parameters and the data type that has to be used with each condition are listed below:

Managing your mailbox:

  • Move to Folder - You can select a folder and move the email to a specific folder. You can also create a new folder if you haven't already created one for a set of conditions.
  • Apply a selected Tag/Flag - You can choose a tag that can be applied to the email. 
  • Mark as read/Unread - You can change the Read/ Unread state of the email. Ex: You can mark certain notifications as read, without adding them to the unread count. 
  • Archive email - You can archive emails that meet the conditions specified by this filter. You can then view all archived emails in the View archived section within your email listing.
  • Set a reminder - You can set reminders for the email processed by this filter based on the conditions provided. You'll be reminded through notification based on the reminder preset configured by you.
  • Snooze for - You can snooze emails processed by this filter based on the conditions provided. The emails you snooze will appear on top of the list of the folder at the set snooze time. You can also access the snoozed emails from the Snoozed folder in the left menu.
  • Send an auto response - You can send an auto-response for the email processed by this filter based on the provided conditions. You can choose the preferred auto-responses from a list of predefined templates.
  • Delete the email - You can move email directly to Trash based on some conditions. Ex: It will be useful when some newsletters keep coming, even after unsubscribing several times. 
  • Delete after N days - This action deletes the emails that fall under the defined condition after the specified number of days. This action will be useful in cases where certain notifications are necessary at that point but are not meaningful after a few days. A tag with the number of days left for an email to be deleted (up to 10 days) will display at the end of the respective emails at the email listing.
    delete after n days

     It is always advisable to use the 'Delete after N days' action with the 'Move to Folder' action because you will have an idea that emails in that particular folder will be deleted after the specified number of days. Also, make sure that this folder is named relevantly to convey that the folder content will be deleted after a few days.
  • Forward the Mail (to a different email address) - Conditional Forwarding - Instead of forwarding all emails, you can define some conditions based on which only some emails can be forwarded. 
  • Don't add attachments to Attachment Viewer - Incoming attachments will not be added to the attachment viewer if this action is selected. If you decide that a record of certain attachments is enough in just emails, and doesn't have to be added to the attachment viewer, this action can be used. 


If the Condition Type you have selected is Any of these conditions for any of the following actions, you will be prompted to re-check your Condition Type:

  • Move to Spam
  • Delete the email

Processing your emails:

  • Add Mail as Notes - Add the entire email as a note, with the subject as Title and the email content as the Notes. 
  • Assign Mail as Task - Add the email as a Task, with the Subject as Title and email content as Description
  • Post to Cliq Channel - You can choose to share an entire email as a link/ only the attachment(s) in the email to a chosen Zoho Cliq channel that you are a part of.
  • Custom Functions - Customise the filter actions and conditions using the available parameters using Deluge scripting via Zoho Creator. Learn more.

Managing your attachments:

You can configure filters to upload the attachments from emails, that match your conditions, to certain file storage services or choose to not add attachments to Attachment Viewer using one of the following filter options. 

  • Add to Dropbox
  • Add to Google Drive
  • Add to OneDrive
  • Add to Box
  • Add to Zoho Workdrive
    • Add attachment link to CRM - When you choose Zoho Workdrive, you'll also have the option to add the attachment from the email as a Workdrive link to your CRM module if the sender is a Lead in Zoho CRM.
  • Don't add attachments to Attachment Viewer - Attachments that are part of your emails, will not be added to the Attachment Viewer if you select this action.

Once you have selected the storage service of your choice, you can also choose the file you wish to upload through the filter. You can upload only the attachments in the incoming email or also upload the email content as EML or HTML.
