Why do you need it?

Here are some cases when email preview helps you see and fix issues prior to sending newsletters out to avoid negative impact.

Missing alternative text

Sometimes images can don't load due to a bad connection or can be blocked by email clients by default. You want to make sure that you have the alt text instead, thus even without images your email makes sense. Alt text also prevents from being reported as SPAM and is one of the cardinal rules for email accessibility.

Custom fonts

A custom font can become a part of your brand's style. Don't let it become ruined with a poor rendering of some email client. Using email testing tools can ensure you that everything looks right in any email client.

Buttons

Some email clients, such as Outlook, might display rounded buttons just like squares or even without any frame at all. That means, that button can even become invisible if its font color matches with the email background color. Testing your emails can help you to avoid losing your CTA buttons.

Issues with background image

When background complements entire email design and makes it look complete, email testing tools are necessary, because email client test shows if your email looks well and if all email elements render correctly across multiple email clients.
