DKIM Signature brakes with HTML (multipart/alternative)

DKIM Signature brakes with HTML (multipart/alternative)

These are 2 emails sent FROM Woocommerce with PHPMailer 5.2.14 VIA Zoho's smtp TO Gmail.

One is sent as multipart/alternative
SMTPS id 1472887925932653.1288036547104; Sat, 3 Sep 2016 00:32:05 -0700
Message-ID: 2794079fbfa406a809a82a690ab1f488

One is sent as text/html
SMTPS id 147289704238276.96960297971964; Sat, 3 Sep 2016 03:04:02 -0700
Message-ID: 11b0666e538f89fb1fb1a757a91292ec

The only difference between these mails are the Content Type and the html in the body of the second one. 


The one sent as multipart/alternative gets a verified DKIM signature, but the one sent as text/html does NOT, by Google ( body hash did not verify).

So Zoho is doing something to the html email after it has signed it? I would like to know what and why. Either I have to fix something or you need to do it at your end. As far as I can see it you use c=relaxed/relaxed in your signature, isn't that suppose to deal with this?

For an email campaign, you may think you have all the essential elements for lead conversion—a big mailing list, an attractive template design, and the most-engaging message content, but after hitting the ‘send’ button, you may not get the expected conversions. Wondering why? Here’s one of the major reasons. Many marketers miss out on sending the email campaign the right way. Did you know that you should not be

The process of persuading your customers to open your email and click on your call-to-action becomes easy when you understand the psychology behind their behavioral traits. Time to turn into a psychologist! Let's get to the basics—you want your emails to resonate well with your recipients. So, what's the primary thing involved here? It's

A preheader is the short text that follows the subject line in an email. The preheader is designed to hint at what your email message is all about. A good preheader should act as a second subject line and convince your contacts to open the email. Now, let's learn the best way to craft a preheader. Your subject line and preheader should work together and accurately convey the gist of your email. Keep

                                                              If crafting content for emails, getting creatives done, and running email campaigns is your love, then unsubscribes are the heartbreakers.  You can save your emails from being unsubscribed/trashed by adding a proper subscription-preferences option in your emails (works best at the time of signup). Giving subscribers the option to choose what they want to receive from you and decide how often (frequency of the emails) your emails should hit their inboxes will increase the reach of your campaigns manifolds.
