We have a product, GreenArrow Monitor, that is a fairly standard inbox rate monitoring tool. Senders incorporate the Monitor seed list, our robot collects and collates the data, users see the results, merriment may or may not ensue.
Recently we had occasion to investigate weirdness in Hotmail stats. We would expect, for any campaign, given identical messages and uniform rules, they should all go to the inbox or all to the bulk folder. Additionally, if there is zero inbox delivery, the open stats should be miserable. What we have been seeing is fractional inbox rates (45%?) and cases where the reported inbox rate was zero but the unique opens were at 40%. What we found was that each seed account had extensive safe- and blocked-sender lists. These differed between accounts. Since the accounts have no human users, this is unexpected. Checking my own outlook.com account, used for investigating individual client problems, I see unsolicited entries in the safe-sender list. I begin to formulate a plausible hypothesis that explains why so many of my clients see comparativey dismal open rates for their fully AUP-compliant email at hotmail, whilst seeing excellent response rates elsewhere. Anyone have insights on this? mdr -- We must not confuse statistical probability with some transcendental and utterly compelling force. -- Unspiek, Baron Bodissey (Life, Volume II) _______________________________________________ mailop mailing list [email protected] https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
