Newsletters are the bane of my existence. Luckily, our team at Hanely Wood no longer has to work on them. Here are some tidbits we learned during the time we spent managing the design of our HTML newsletters.
Newsletter Testing
A newsletter is a great way to stay in touch and provide useful and interesting information to your subscribers. But you don’t want to publish your newsletter without checking whether it looks good on all devices.
Testing newsletter HTML is an important step in the process of creating a web-friendly version of your email. Simply viewing the .html file in a web browser isn’t good enough.
To test your newsletters and verify that they appear properly on today’s most popular email clients, you should use an email testing tool. You can use the tools below to test how your HTML newsletter is going to look on different devices, browsers, and email clients.
Email on Acid
For the past few years, we’ve relied on Email On Acid to test our newsletters.
Here’s what we like about it:
Many Options for Email Clients
Email on Acid allows you to test with multiple email clients on different browsers, desktop email clients on different operating systems, and mobile email clients on different devices. You’ll be amazed (and frustrated) to learn how different (and potentially jacked up) your newsletter can look in the same email client, but on different operating systems.
Mobile Emulator
The browser and desktop tests only provide screenshots, however, the mobile tests can be viewed in a mobile emulator, allowing you to interact with your newsletter. This can be helpful in determining the usability of your newsletter on a mobile device.
Tips and Tricks
This feature is great for troubleshooting issues with your newsletter. Maybe you can’t use floats or your embedded CSS is getting stripped out. Here’s an example of the Tips and Tricks section for Outlook 2010 on Windows 7:
Starting here will help you save time in fixing issues with your newsletter.
Sharing Results
Email on Acid allows you to share your test results, which is useful for sharing with someone who doesn’t have an account. We use this to share with our stakeholders so they can take a look themselves in case we missed anything during QA.
Litmus
One drawback of Email on Acid is that the screenshots are not always an accurate representation of how the newsletter looks on a particular client. There have been times when we’ve been alerted to a visual issue with our newsletter that didn’t appear in an EOA test, but on the actual email client on a given operating system. To recreate these issues, we’ll use Litmus Putsmail to send off a test email to one of our email addresses, then open it in the email client on the operating system in question (usually using some type of VM software such as Parallels).
In addition to Putsmail, Litmus has a suite of email testing features that are comparable to Email on Acid. I have not used Litmus myself, but you can check it out at https://litmus.com/ to see if it’s a better option for you.
Tips
Use a Boilerplate
Don’t start from scratch. Use a boilerplate because it’s likely been implemented in such a way that the quirks specific to each email client have already been worked out for you. We used a boilerplate off of Emailology.org and customized it from there. Though Emailology no longer exists, I’ve been able to find a gist of the boilerplate at https://gist.github.com/cemerson/4495931.
I’ve copy-pasta’d the HTML below, just in case the gist URL disappears from the internet as well:
<!-- ***************************************************
********************************************************
HOW TO USE: Use these code examples as a guideline for formatting your HTML email. You may want to create your own template based on these snippets or just pick and choose the ones that fix your specific rendering issue(s). There are two main areas in the template: 1. The header (head) area of the document. You will find global styles, where indicated, to move inline. 2. The body section contains more specific fixes and guidance to use where needed in your design.
DO NOT COPY OVER COMMENTS AND INSTRUCTIONS WITH THE CODE to your message or risk spam box banishment :).
It is important to note that sometimes the styles in the header area should not be or don't need to be brought inline. Those instances will be marked accordingly in the comments.

<!-- Using the xHTML doctype is a good practice when sending HTML email. While not the only doctype you can use, it seems to have the least inconsistencies. For more information on which one may work best for you, check out the resources below.
UPDATED: Now using xHTML strict based on the fact that gmail and hotmail uses it. Find out more about that, and another great boilerplate, here: http://www.emailology.org/#1

Hate Outlook.com’s Contextual Highlighting?
Use the following snippet to override Outlook.com’s contextual highlighting:
/* Overrides Outlook.com Contextual Highlighting */
span {
color: #000;
border-bottom-width: 0;
border-bottom-style: none;
}
Avoid Deeply Nested Tables
At some point, our newsletter layout was a little more complex than they are now. This resulted in some nested tables that were affecting Outlook. We ended up with a huge gap of whitespace in the middle of our newsletters. We followed the tips from Email On Acid, however, nothing worked. So don’t do this.
I actually don’t recall if we ever fixed this issue. We moved on to a simpler template shortly after.
Include Both Embedded CSS and Inline CSS
Embedded CSS
Embedded CSS is useful for mobile design and overriding the styles of extra elements inserted by the email client.
Here’s a snippet that ensures all your links are the desired color and style, taking into account that Yahoo inserts a span.yshortcuts inside all links:
/*Yahoo adds span.yshortcuts inside all links*/
a:link,
span.yshortcuts {
color: #000; /* Link color must be set inline for Gmail*/
background-color: none;
border: none;
text-decoration: none;
}
p a:link,
p span.yshortcuts {
text-decoration: underline;
}
p a:active,
p a:visited,
p span.yshortcuts:active {
text-decoration: underline;
}
a:active,
a:visited,
span.yshortcuts:active {
color: #000;
background-color: none;
border: none;
text-decoration: none;
}
a:hover,
span.yshortcuts:hover,
span.yshortcuts:focus {
text-decoration: underline;
}
Inline CSS
Gmail does not supported embedded CSS. Use either of the following inline CSS tools to convert your embedded CSS into inline CSS:
- https://www.campaignmonitor.com/resources/tools/css-inliner/
- https://putsmail.com/inliner
- https://foundation.zurb.com/emails/inliner-v2.html
Learn How to Walk Away
Depending on the complexity of your newsletter, the time and frustration to get it to look exactly the same on every supported email client for each platform are simply not worth it. Maybe your link shows up purple in Gmail despite the styles setting them to blue. Maybe the spacing between paragraphs in Outlook 2016 is a little more than desired. If your content is still readable and still maintains the basic layout, do away with the nuances if you haven’t been able to solve them within a reasonable amount of time.
That’s all I have and I hope I never have to experience the pain of creating newsletter templates ever again. Good luck!
