Why would I care about the size of my email message?
JangoMail measures both number of emails sent and total data bytes sent from your account. Both are a factor in your account's pricing. Now, the Spam Check tool will include the exact size of your email message in bytes, taking into account the HTML/Plain Text parts, any attachments, and embedded images, if you choose to set your email marketing campaign that way.
Here's a live example from our customer, Popcorn Palace:

And here is the result of the Spam Check:

If this email did not use the Embedded Images feature, the total size would be around 1,500 bytes, or 1.5 KB, for a size savings of over 99%!
