You might have a great marketing message and a strong call to action. However, if your email looks bad in the inbox of your subscriber, it won’t do much good. Emails look unprofessional when emails don’t display properly. They can lower how many people engage with them. This can also hurt your reputation as a sender. This is making it harder for your emails to get delivered in the future.
On average, about 83–85% of marketing emails actually reach the inbox. That means nearly 1 in 6 emails never get through because of spam filters, low engagement, or technical issues.
When emails don’t show up correctly, readers might get confused, buttons might not work, or the content might be hard to read. If people keep deleting, ignoring, or marking your emails as spam because they look bad, email providers notice and think your messages are not wanted. Over time, this lowers your email deliverability. This is making it more likely they will end up in the spam folder. Email rendering is here to help in such situation.
What is Email Rendering?
Email rendering means how an email looks when someone opens it in their email app or program. Email apps don’t all show emails the same way unlike websites. Each app reads the code of email differently.
Big email apps like Gmail, Outlook, and Apple Mail all use different systems to display emails. So, an email might look perfect in one app but messy or broken in another. For example, Gmail often needs special coding to show things correctly. On the other hand, Outlook uses an older system that can’t handle some modern designs.
Marketers can’t expect an email that looks good in one place to look good everywhere because of these differences. They need to make sure their emails work well on different apps, whether people check email on their phone, computer, or online.
How Bad Rendering Hurts Your Reputation?
When your emails don’t show up properly, it is more than just annoying for your readers. It can actually hurt your reputation as a sender in three big ways:
- Less Engagement
- More Spam Complaints
- More Unsubscribes
If your emails look messy, have broken layouts, or hard-to-read text, people are less likely to open or click on them. Email providers watch these actions closely. When fewer people interact with your emails, providers think your messages are not important and may send them to spam in the future.
Badly displayed emails can look suspicious or broken. This is making people mark them as spam instead of reading them. Spam complaints are one of the strongest reasons email providers lower your reputation and email delivery as well.
If subscribers keep seeing confusing or poorly displayed emails, they are more likely to unsubscribe. A lot of unsubscribes tells email providers that your list is not healthy.
All these things together tell email companies that people don’t want your emails. This makes it harder for your messages to reach the inbox.
The Proactive Shield: How to Prevent Rendering Issues
Here are some easy steps to keep your emails looking good and protect your sender reputation.
Strategy 1: Foundational Coding Best Practices
Good email display begins with simple, solid coding. Using tools like MJML or Foundation for Emails can help make sure your emails work well across different email apps.
Keep your code simple and use inline CSS which most email apps support. Avoid fancy layouts or complicated styles that many email clients don’t handle well. Always add helpful alt text for images and use backup background colors. If images don’t show up, your message still makes sense this way.
Using simple, careful coding helps prevent email display problems and keeps your content easy to read no matter where it is opened.
Strategy 2: Rigorous Pre-Send Testing (The Critical Step)
Just sending a test email to your Gmail is not enough. Emails can look very different in Outlook, Apple Mail, or on phones and tablets. That is why using inbox preview tools is so helpful.
These tools show you screenshots of how your email will look on many different apps and devices before you send it out. You can catch problems like broken layouts, missing buttons, cut-off text, or image issues in the email apps your audience uses most this way.
Services like Aurora SendCloud have Inbox Preview features that let you check your emails across Gmail, Outlook, iPhone, and more. Testing your emails this way helps avoid surprises and keeps your emails reaching inboxes.
Strategy 3: Maintaining a Clean List & Getting Feedback
Having a clean email list makes your campaigns work better. Regularly remove email addresses that don’t open or respond to your emails. Watch for bounce rates and feedback from email providers to spot if certain issues are causing people to complain.
Pay attention to feedback from your subscribers or your email stats. This helps you to find and fix any display problems quickly before they hurt your results.
Common Beginner Mistakes to Avoid
Even experienced email senders can run into common problems with how their emails show up:
- Outlook uses a special system to display emails. It often does not handle modern designs correctly unless you test carefully.
- Many email apps block images by default. If your email relies only on images without backup text, people might miss your message.
- A button might look perfect in one email app but lose its style or stop working in another.
- Custom fonts can get replaced by basic ones in some emails. This will be messing up the look and spacing of your email.
- Users may have to zoom in orscrollsideways without testing for mobile. This makes the email hard to read and less engaging.
Avoiding these issues helps your emails look better to subscribers and improves your chances of getting them into the inbox.
Conclusion
If an email often gets low engagement, spam complaints, or unsubscribes, Internet Service Providers (ISPs) see it as a sign of a problem sender. Email display is not just about how it looks. It also affects how ISPs judge your reputation as a sender and where your emails end up.
Putting effort into good email design is essential. This is true including solid coding and necessary pre-send testing like Aurora SendCloud’s Inbox Preview. It is not just a nice extra. It is crucial for running successful email campaigns and ensuring your emails get delivered.
Make sure to include inbox preview testing as a regularstep in your process before sending your next email. Your reputation and how many people open your emails depend on it.
