Sponsor Delivery Report Generator

Turn your send, open, and click numbers into a clean report your sponsor doesn't have to take on faith. Works with any ESP. Nothing you enter is sent to a server.

Campaign details

Delivery numbers

Enter your own send/open/click numbers — this tool doesn't verify them for you. It just formats them into a report you can send. Numbers are self-entered, not independently measured.

Preview

Fill in your newsletter name, sponsor, and at least sends or opens to see a preview.

Every newsletter that sells direct sponsorships eventually owes an advertiser proof the campaign ran. Most publishers put together a screenshot and an estimated open rate by hand, every time. This tool at least standardises the format — enter the numbers once, get a report you can attach to an email or print.

It doesn't solve the harder problem: these numbers are only as good as what you typed in. An ad server built on open-time serving logs the real decision at the moment a subscriber opens — including the no-fill outcomes — so the report reflects what actually happened, not an estimate. That's what MailAdx's Publisher Portal produces automatically, for every sponsor, every send.

Frequently asked questions

Does this tool verify my numbers?
No. It only formats the sends, opens, and clicks you enter into a clean report — it doesn't check them against your ESP or ad server. If you need delivery numbers that are independently verified rather than self-reported, that requires an ad server that logs the decision at the moment of open, like MailAdx.
Is anything I enter sent to MailAdx or stored anywhere?
No. The report is generated entirely in your browser — nothing you type is sent to a server or saved. Refreshing the page clears it.
Can I use this for any ESP, not just MailAdx?
Yes. This tool has no dependency on MailAdx or any specific ESP — it just does the open-rate and CTR math and lays it out as a report. Use whatever send/open/click numbers your ESP's own analytics give you.
How do I send the report to my sponsor?
Use "Print / Save as PDF" for a document you can attach to an email, or "Copy summary" for a plain-text version to paste directly into an email or Slack message.

Skip the manual report every send
