(Deliverability) The latest metrics

Latest posts | Feed | By Mark Brownlow

It's good news and bad news (isn't it always?) on the deliverability front. According to Lyris and their latest report, deliverability rates are broadly high at the major US and European ISPs. But the overall optimistic glow hides one or two problems.

Average gross deliverability across all monitored ISPs rose from Q3 2005 to Q4 2005 by 2 percentage points to 89%. That's a healthy, welcome trend.

Not all ISPs are doing a good job of getting permission-based opt-in mail through to inboxes, though.

Hotmail.com, for example, falsely filtered 15.9% of the opt-in email, almost double its false positive rate in the previous quarter.

So the message is, keep alert and keep watching those domains with strongest representation in your list. An improvement in global deliverability rates doesn't help you if all your customers use hotmail.com.
