Top Senders is the Analytics tab that ranks the addresses sending the most email to AliasFleet aliases in a selected time range. Each row shows the sender address, the number of emails received, and the share of total volume. The ranking identifies noisy senders and unexpected mail, and a sender can be blocked from the same tab.
Top Senders is a Pro feature. Accounts without access see a Pro badge on the tab. All aliases on the account feed the same list, so the ranking covers every alias at once.
How do I open the Top Senders list?#
- Open Analytics: select Analytics in the sidebar.
- Open the Top Senders tab: click Top Senders in the tab row, next to Traffic & Distribution and Alias Performance. The tab label shows a count in brackets, for example Top Senders (12).
- Read the list: the five highest-volume senders appear in rank order, with a distribution section below them.
What does each row show?#
Each row in the list shows the same five pieces of information, plus an avatar circle with the sender's initials.
| Item | What it means |
|---|---|
| Rank | Position in the list, from 1 for the highest-volume sender down to 5. |
| Sender name or domain | The sender display name where one is known, otherwise the sending domain. For example, a row can show github.com as the name for mail from noreply@github.com. |
| Sender address | The full sender address in fixed-width text, for example noreply@github.com. Hovering the name shows the full address in a tooltip. |
| Count | The number of emails received from that sender in the selected time range. |
| Ban icon | A block action that appears when the row is hovered. Clicking it starts the block flow described below. |
Below the list, a Distribution section shows the top three senders as bars, each labelled with a percentage share of total volume. A sender at 40% sent two in every five emails.
How do I change the time range?#
- Find the range buttons: the 24H, 7D, 30D, and 90D buttons sit at the top of the Top Senders card.
- Select a range: click a button to reload the list for that period. The default range is 7 days.
- Compare ranges: 90D gives a long-term picture of which senders dominate over time, and 24H shows a sudden spike from today.
The range applies to the whole Top Senders list, including the distribution bars.
How do I block a sender from Analytics?#
- Hover over the sender row: the ban icon appears at the right of the row.
- Click the ban icon: the tooltip reads Add to Blocklist. The app opens the Sender Rules page.
- Open the add dialog: the dialog does not open on its own and the address is not filled in. Open the add dialog, enter the full sender address as an exact-match blocked rule, then save the rule.
- Confirm the rule: the new rule appears in the Blocked list on the Sender Rules page, and later mail from that address is stopped before forwarding.
For the full rule options, including blocking a whole domain or a wildcard pattern, see Using Sender Rules.
What can the Top Senders list tell me?#
An unknown sender near the top. An unrecognised sender ranked first or second is worth checking. The address itself usually names the source: a shop, a newsletter service, or a service signed up for with one alias. If the mail is unwanted, block the sender or deactivate the alias it reaches.
One sender dominating the list. Newsletters and automated mail often take the top rows. For example, a daily deals newsletter can send 30 emails in a week while every other sender sends fewer than five. A count that high from one address points at a subscription to cancel or a sender to block, rather than a problem with the alias.
A sudden spike after a quiet period. A sender that jumps to the top of the 24H view after months of silence can mean a breach put an alias on a new list, or a service started a new campaign. The Deliverability & Bounces tab is the next place to check when mail also starts failing to arrive, since a spike in volume and a spike in bounces often share a cause.
Which senders to keep. The list also works in reverse. A bank, a utility, or a work system near the top is normal traffic, and the counts confirm those senders still reach the aliases as expected.
Troubleshooting#
The list is empty. The card shows No sender data yet with the note Top senders will be listed here once emails arrive. No mail arrived in the selected range. Switch to 90D, or wait until mail reaches an alias.
The list fails to load. The card shows Failed to load top senders with a Retry button. Check the connection and click Retry. If the error repeats, reload the Analytics page.
The Sender Rules page opens without the address filled in. Add the rule by hand: open the Sender Rules page, open the add dialog, and enter the sender address as an exact-match blocked rule. The address to enter is the full sender address shown in the Top Senders row, for example noreply@github.com.
A sender shows a domain instead of a name. The list shows the sending domain when no display name is known for the address. The full address is still shown in smaller text under the name, and hovering the name shows it in a tooltip.
The counts look wrong after changing the range. Each range reloads the list from the start. A sender ranked first in 7 days can drop out of the top five in 90 days if its volume was a short burst, and a steady low-volume sender can climb over 90 days.
