This document outlines the functionality and characteristics of the Gmail Reader node, which enables automated email processing from Gmail accounts.

​
Node Inputs

The Gmail Reader node accepts the following inputs:

  • Label: The Gmail label to read from (default: ‘INBOX’)
  • Number of Emails: Maximum number of emails to process. Leave blank to read all emails.

​
Optional Settings

  • Search Query: Optional Gmail search syntax to filter emails
  • Mark as Read: Whether to mark processed emails as read (default: False)
  • Ignore Read Status: If checked, this will include both unread and previously read emails in your search. By default, only unread emails are processed
  • Read Full Thread: If checked, the full message chain will be read for each email thread (default: False)

​
Date Range Filtering

Filter emails by a specific time period, this option is available under Show More Options

  • Use Dates?: Enable this toggle to filter emails by time period

  • Date Range: Choose from preset ranges for quick filtering:

    • Last 24 Hours
    • Last Week
    • Last Month
    • Last 3 Months
    • Last 6 Months

  • Use Exact Dates?: Toggle this option to specify custom date ranges

    • When enabled, you can set precise Start and End dates
    • When disabled, the preset Date Range selection is used

  • Start Date (UTC): The beginning of your custom date range (only available when Use Exact Dates is enabled)

  • End Date (UTC): The end of your custom date range (only available when Use Exact Dates is enabled)

Date filtering is useful for:

  • Historical email analysis
  • Periodic reporting
  • Retrieving emails from specific events or timeframes
  • Automating regular email processing batches

Note: When “Use Exact Dates?” is enabled, you can expose the Start Date and End Date parameters through “Configure Inputs” and connect them directly to the Datetime node for dynamic date ranges.

​
Node Output

The Gmail Reader node produces the following outputs (all in list format):

  • Email Bodies: Content of the email messages
  • Attachment Files: Names and contents of attached files

Note that multiple attachments are separated by a comma, eg: PDF1, PDF2. You can use the Split Text node here to output a list with each file.

  • Message ID: Unique ID of each individual email
  • Thread ID: Unique ID of the entire conversation thread that can contain multiple emails
  • Sender Addresses: Email addresses of senders
  • Recipient Addresses: All recipients (including CC/BCC)
  • Subjects: Email subject lines
  • Dates: Date & timestamp of emails (in UTC)
  • Sender Display Names: Names of the email sender

​

  4. Date filtering in UTC timezone may not match your local time

In summary, the Gmail Reader node streamlines email processing tasks by providing automated access to Gmail content, with flexible filtering options, date range controls, and comprehensive data extraction capabilities.
