Add a "Delivery rate" calculation to statistics summary page?

[zmiller]

Hi,

Could you consider adding "Delivery rate" which would be calculated as:

[(total sent - (bounced + spam)) / (total sent)] X 100%

and it could be displayed as per my mock up screenshot attached?

Thanks for consideration!

Dear Zach,

If the delivery rate is calculated based on bounces, the end result could be definitely wrong unless you really know the number of emails that were delivered. As there are a lot of cases when you don't get a bounce notification from the end server but they put the email in backoff queue and then trash it. So better if we say it "Estimated Delivery Rate" instead of "Delivery Rate". As when you connect your Mumara with any of the ESP account, Mumara tells you the actual delivery rate.

I agree this would be very valuable.

But displaying delivery rate without actually knowing the emails that were reached to the mailbox would be falsy. As when Mumara says "Sent", it means Mumara did the job. For the SMTP case, it's hard to know which emails were actually delivered, we only know which were bounced. But the law of stats says that (total_sent - total_bounce) is never equal to the total delivered as there are other statuses as well e.g. queued. rejected, injected, etc. It's only possible to get these numbers when your node provider sends back all statuses via callbacks. Mumara has covered almost all statuses and when you connect a supported ESP account, it can work. But as 90% of the clients use SMTPs, so we haven't added the Delivery rate.

We have something developed for Mumara Campaigns when the case is an ESP, as can be shown in the snapshot below. But haven't launched it yet
