Go to Analytics and click the Trends tab. This has two charts: daily email volume over the selected period, and a peak hours breakdown.
Daily volume chart
Shows the number of emails forwarded each day across all your aliases. Hover over a bar or point to see the exact count for that day.
Useful for spotting patterns — if there's a spike on a particular day, you can cross-reference with your aliases to figure out which service or campaign caused it.
Peak hours
A bar chart showing email activity by hour of the day, shown in your local timezone. Taller bars mean more email arrives during that hour on average.
This tells you when most of your alias traffic happens. If you notice a lot of email arriving at unusual hours (like 3am), it might indicate automated senders or traffic from a timezone different from yours.
Changing the time range
The trends charts reflect whatever time range you've selected at the top of the analytics page. A 7-day view gives you daily detail; a 90-day or year view shows broader patterns and smooths out individual spikes.
