While testing a recent html email, I encountered an lapse in my understanding about optimization.
Example One: http://www.americanwinery.com/newslette … index.html
Example Two: http://promotions.newegg.com/NEemail/Ju … -Moredeals
Example one is the email I have been working on. All images have been optimized as well as the code behind them to the best of my know how. However when opening each email (uncached), example two loads multitudes faster than my own (example two: less than 2 seconds - example one: nearing 5 seconds). Yet upon investigating the emails construction, image size and number I found no reason that example one should not load faster by strides.
If anyone has any advice on how these two cases differ and what can be done to example one to increase performance, please shed some light.
How are you testing? Are the images coming from the same server?
No, I am actually looking at the images in each email's webversion using firebug.
So they could be being served by different machines - that may account for some performance differences, making it tricky to confirm.
