How to Calculate Average Emails Sent per Day, Week, or Month in Outlook
Product
Microsoft Outlook
Device & OS
not provided
Scenario
Tracking daily, weekly, or monthly email output for productivity monitoring and reporting.
Observed behavior
Outlook lacks a dedicated built-in reporting tool for average sent emails, requiring users to manually count sent items within a date range and calculate the average.
Before you start

Ensure your Outlook client is fully synced with your mail server so that your Sent Items folder contains an accurate and up-to-date history of all outgoing messages.

Solution 1Recommended

Use a Custom Search Folder to Count and Calculate Sent Emails

Create a custom Search Folder filtered by date to count total sent items, then manually calculate the average based on your selected timeframe.

While Outlook does not have an automatic analytics button for sent email averages, its Advanced Search and Search Folders features allow you to isolate and count emails perfectly.

By setting up a dynamic Search Folder, you can continually monitor your sent volume for any given time period.

1
Create a New Search Folder

In the left-hand Outlook folder pane, scroll down, right-click on 'Search Folders', and select 'New Search Folder' from the context menu.

2
Select Custom Search Folder

Scroll to the bottom of the New Search Folder window, select 'Create a custom Search Folder' under the Custom section, and click the 'Choose' button to name it (e.g., 'Sent Emails This Month').

3
Filter by Sent Items and Date

Click the 'Criteria' button. Under the 'Messages' tab, ensure you are targeting sent emails. Go to the 'Advanced' tab to specify your date range criteria (e.g., 'Sent' - 'this month' or 'this week'). Click OK to apply.

4
Display Total Item Count

By default, Outlook shows unread counts. Right-click your newly created Search Folder, choose 'Properties', and select 'Show total number of items'. This will display the exact number of sent emails next to the folder.

5
Calculate the Average

Take the total number of items displayed and divide it by the number of days, weeks, or months in your chosen period to determine your average email volume.

Data Accuracy: Check your AutoArchive settings before calculating. If Outlook is configured to archive sent items after a short period, older sent emails may not appear in the Search Folder, resulting in an inaccurate average.

Frequently Asked Questions

Can I export the Search Folder results to Excel for easier calculation?

Yes. You can open your custom Search Folder, press Ctrl+A to select all the emails, copy them using Ctrl+C, and paste them directly into a blank Excel spreadsheet. This allows you to use Excel formulas to calculate averages and create charts.

Why is my Search Folder not showing the exact number of sent emails?

By default, Search Folders are configured to 'Show number of unread items'. Because sent emails are usually marked as read immediately, the count might appear as zero. You must right-click the folder, go to Properties, and manually switch the setting to 'Show total number of items'.

Does Outlook have any built-in analytics add-ins for email statistics?

Microsoft offers analytics tools like Viva Insights for enterprise users, which provide statistics on email habits, focus time, and collaboration. However, for a simple and precise 'emails sent per day' metric without enterprise configurations, the Search Folder method remains the most direct approach.
