During 2006 the top 10 email domains have grown from representing 61.25% of email web form requests in January to 65% in December.
This growth indicates, now more than ever, it’s important to test your email newsletters for both how they look at top domains as well as overall email deliverability. Having issues with just a single top domain can significantly impact campaign results.
Interesting standouts:
- aol.com steadily falling from 9.35% of requests in January to 7.82% in December.
- gmail.com steadily rising from 3.49% of requests in January to 4.86% in December.
- 8 of the top 20 domains are outside of the United States.
- 6 of the top 20 domains have deliverability managed by Yahoo (~28.91% of requests in December).
