Return Path’s most recent Global Email Deliverability Benchmark Report reveals a “historic decline” in inbox delivery rates for the second half of 2011. Traditionally 20% of emails failed to reach in the inbox, but this new data shows that an average of 23.5% of email is getting marked as spam or going missing.
When looking at delivery rates by region, there are some significant differences. Globally, EMEA experienced the highest delivery rates at 85%, followed by North America at 79%, CALA at 72% and APAC at 67%. CALA led the category in the highest percentage of emails categorized as spam at 10%. However, 28% of APAC email goes missing.
