To send standard and custom reports by email in GA4, follow these steps:

1. In Google Analytics, select Reports on the left.
2. Open the report you want to send as an email.
3. On the top right of the report, click Share this report > Send Email.

Note: If you can't find the 'Send Email' option, it may mean that you don't have permission to schedule a report. Only administrators can send reports by email.

4. Complete the following fields to send the report:

   • Report name: Enter the name of the emailed report. The report name appears in the email body.
   • Recipient list: Select up to 50 email addresses to receive the email. You can type the email addresses to find them quickly. You can select any user who has access to the property. Users who are removed from the property are also removed from any recipient lists.
   • Report format: Choose the file format for the emailed report, either PDF or CSV. The report is sent as an attachment to the email.
   • Language: Choose the language of the report when it's emailed to the recipients.

5. Click Send to send the email. You can only send it if you've included at least one recipient and selected a valid name.

You can also send emails with the “Schedule Email” option. Learn more about scheduling reports.
