Testing is one of your fastest routes to achieve #NoFailMail. But, every day, we see emails in our inboxes with fails that are so obvious, it\u2019s clear nobody took a second look before hitting \u201csend.\u201d<\/p>\n

Whenever you touch a live email, you introduce the chance that something could break. Plus, email clients drop or change support for HTML, CSS, and other key components without notice. That\u2019s why every email deserves to have an email QA test<\/a>, even if you use a template that you just tested yesterday.<\/p>\n

Testing helps you spot and fix problems in your email messages before they go out to your subscribers. It\u2019s something you should build into your email workflow so that it\u2019s part of your regular process, not something you do haphazardly or if time allows.<\/p>\n

Anatomy of a Broken Email<\/h2>\n

Email issues that make marketers shudder\u2014and how email testing<\/a> helps you catch and fix them before you send.<\/p>\n

Here are five potential trouble spots to test for:<\/p>\n

Email Fail #1: Broken links<\/h2>\n

Don\u2019t miss out on a conversion opportunity by sending your subscribers to a 404 page or an outdated landing page. The broken link that sent your customers to no-man’s-land is one of the most obvious errors to spot and fix through careful testing.<\/p>\n

Unlike URLs in plain-text emails, the URLs in HTML messages usually hide behind hyperlinks within your copy, images, or call-to-action buttons, so they can\u2019t just be checked with a scan of the eye. You\u2019ll have to click each one of them to ensure they\u2019re sending the subscriber to the intended destination\u2014and to ensure that click-throughs are being tracked so you can measure your campaign\u2019s performance.<\/p>\n

Automate your link checks with Litmus Checklist<\/h3>\n

Manually checking each link can be a cumbersome process, especially when you\u2019re sending complex campaigns with many links. Litmus Checklist<\/a> automates this step for you.<\/p>\n

Link checking made easy in Litmus Checklist<\/figcaption><\/figure>\n

Our link check feature automatically checks all of the links in your email to make sure that they are valid and lead to the right landing pages, and runs the link against the Google Safe Browsing database to check for suspected phishing and malware pages. Plus, Checklist verifies that click-throughs are being tracked and makes it easy for you to double-check your Google UTM parameters in case you\u2019re using them for performance tracking.<\/p>\n

Email fail #2: Broken dynamic content<\/h2>\n

Ah, yes\u2013the “Hello, %%first_name%%” fail. Dynamic content is great when it works. When it doesn’t, you look silly, and you’ve lost a great conversion opportunity.<\/p>\n

Don’t operate on faith that your data integrations are working in emails with dynamic content. Always test your emails to ensure that your ESP\u2019s merge or personalization tags are working properly and pulling in the correct information. Also, make sure you have a good fallback to cover instances where you are lacking subscriber data.<\/p>\n

If you have switched ESPs, it\u2019s especially important to test. ESPs often have different merge tags, so you\u2019ll have to verify that your dynamic content is still working.<\/p>\n

Email Fail #3: Email not rendering correctly<\/h2>\n

Every email client, whether it\u2019s a desktop, webmail or mobile version, displays the same email contest a little\u2014or a lot\u2014differently<\/a> from the others. Plus, email clients can modify or drop their support for HTML and CSS without notifying anyone beforehand. The template that looked so great last week (or yesterday) can be a broken mess today.<\/p>\n

Testing your message across different devices and email clients will help you spot and correct rendering issues before you hit send, and ensures that your email looks great and works well everywhere.<\/p>\n

Email Fail #4: Emails caught in a spam filter<\/h2>\n

Once again, this is an area where something can change without warning and without any action on your part. The domain you use to send email could end up on a blocklist\u2014even though you\u2019re a legit sender<\/a>. If you share a server with other senders at an ESP, anything sketchy they do could end up hurting your ability to reach the inbox. Though your template might not be changing, any changes to your IP address, email authentication methods, or your content can affect your deliverability.<\/p>\n

Email Fail #5: Broken images and incorrect ALT text<\/h2>\n

Great visuals can elevate your email\u2019s design and strengthen your message, but image fails can cause the exact opposite: a jarring subscriber experience. The good news is that most image errors can easily be caught through proper testing.<\/p>\n

Test to be sure you have replaced default, outdated or placeholder images with the correct images, that the images are in the right places in the emails, and that the URLs pointing back to the image sources on your site are correct.<\/p>\n

Even if you use a template, test your emails every time to catch potential mix-ups. Someone could have moved files around and broken the link to the image source. Anything is possible!<\/p>\n

Another key part of image testing is making sure that your email looks good in case images are not supported<\/a>. ALT text (short for alternative text) are the words that show up in the email client to describe an image that’s broken or blocked. A description with well-chosen words can encourage your recipient to turn on images or click a linked image to check it out on your site. Always test your emails with images disabled to ensure that you\u2019ve replaced placeholder ALT text, it\u2019s spelled correctly, and it\u2019s appropriate for the image it\u2019s representing.<\/p>\n

Make your images fail-proof with Litmus Checklist<\/h3>\n

With Litmus Checklist<\/a>, you can preview your email in popular email clients to ensure that your images render as intended. Plus, you\u2019ll get previews of your emails with images off, and we\u2019ll notify you if any of your images are missing ALT text.<\/p>\n
