Monthly trends, as defined in the earlier AliasFleet documentation, compare the current calendar month with the previous full calendar month. The calculation is ((this month minus last month) divided by last month) times 100. The app code in this workspace shows no monthly badge text, so the examples here are illustrative.
Where does a trend badge appear in the app?#
The Aliases page has no stats cards in the app code. The only trend badge on a stats card verified in the app code sits on the dashboard. The Total Forwarded card there, shown on Business and Premium plans, shows a weekly change, in the form "+N% this week", requested over a 7-day window. The stats card component renders the badge with a green upward arrow for growth, a red downward arrow for a fall, and a grey dash for no change, using whatever text it is passed. No "vs last month" text exists anywhere in the app code. The monthly comparison set out in this page is therefore the calculation stated in the earlier documentation, not a badge verified in the live app.
How are the two months defined?#
The earlier documentation defines the comparison by calendar months, not rolling 30-day windows.
This month = from the 1st of the current month until now Last month = the entire previous calendar month
If today is May 14:
- "This month" = May 1 - May 14
- "Last month" = April 1 - April 30
The calendar month window keeps each comparison aligned to a fixed monthly period.
Why can an email from 23 days ago count as last month?#
An email that arrived 23 days ago counts as last month when it landed in the previous calendar month. If today is May 14, an email from April 21 falls in April, which is last month, not in May. The number of days since arrival does not decide the month. The calendar month of arrival decides it.
How is the percentage calculated?#
The calculation below is the definition stated in the earlier version of this page. It is not verified against the live app, because the monthly formula is not visible in the app code in this workspace.
trend = ((this month - last month) / last month) × 100Examples:
| This month | Last month | Result |
|---|---|---|
| 4 | 12 | ↓ 67% |
| 15 | 10 | ↑ 50% |
| 0 | 0 | 0% (no change) |
| 3 | 0 | ↑ 100% |
The 100% case is the rule stated in the earlier version of this page for a move from no activity to some activity. With no baseline from last month, the result is shown as 100%.
The badge examples in this page are illustrative. A rising badge would read "↑ 50% vs last month" and a falling badge "↓ 67% vs last month", following the pattern of the verified weekly badge. The exact monthly text does not appear in the app code.
What does 0% vs last month mean?#
A 0% result appears when both months had the same count. That includes the case where both months had zero activity.
A 0% trend does not indicate an error. A high lifetime total and a 0% trend can appear at the same time, because the total counts every event ever recorded across the account while the trend compares only the two months.
What does a rising trend mean in practice?#
On the documented monthly calculation, a rising Forwarded figure means more mail arrived through aliases this month than last month. A rising Blocked figure means more mail was stopped this month than last month. In both cases, the next step is to find which alias the mail arrived on, because each alias names the service it was given to.
If the extra mail is unwanted, When an Alias Starts Getting Spam, Contain It and Replace It sets out the order: identify the source, create a replacement, update the account address, then pause or delete the alias. How blocked mail is handled is covered in Blocked Emails Explained.
How do monthly trends differ from the Trends tab?#
Monthly trends and the Trends tab answer different questions. A monthly trend is one percentage per stats card, comparing two calendar months. The Trends tab shows charts of daily email volume and peak receiving hours across a selected time range, which suits spotting a spike on a single day. That tab is covered in Trends. The dashboard badge differs again: it shows a weekly change, not a monthly one.
