(Survey) Delivery rate insights
Latest posts | Feed | By Mark Brownlow
ReturnPath just released some figures on deliverability rates at different ISPs and corporate filter services (in the second half of 2005).
Overall, the percentage of email either landing in spam folders or not arriving at all is trending down, which is good. But this does mask a huge variation depending on which ISP you look at.
The non-delivery rate at Gmail, for example, was over twice as high as the average. At Earthlink, this rate was less than half the average.
And, pleasingly, it seems more consumers than you might think take active steps to add corporate domains to their personal address book, thus ensuring delivery of commercial email from those domains.
