What is the optimum size for a HTML email?

Hi Alex,

Do you mean width of the layout, or kilobytes?

If you're using a fixed width, I'd go no longer than 600 or 700 pixels. Everyone has different screen resolutions and e-mail programs. Better of using CSS to design the layout of your html e-mail.

As for filesize/kilobytes, an attachment of up to 500k isn't too bad. People with dial-up internet are obviously prone to more waiting time, so consider your audience. Better to have your images source as absolute (ie. on some web space) so that you don't need to use attachments at all.

For example, in our HTML e-mails to our customers, if there are any graphics in the e-mail, we upload them to a folder on our server, then in the HTML code use something like this:
<img src="http://www.microsofttraining.net/image/email/microsoft.jpg">

Hope this helps.

Hi Rich,
I meant KB size, but you suggested layout size is also a good point.

Thanks for your help!
