This is particularly important if you use Outlook and know that a large percentage of your audience does also. Outlook is one of the trickier email clients to work with and it has a number of formatting quirks.

Nearly all of the email clients will display your HTML slightly differently, this is because each email client has been coded in its own bespoke and unique way, which means they also interpret HTML in different ways.

This interpretation can cause some of your emails to look a little skew whiff in various email clients and perfect in others. For example, you may acquire some unwanted white space in Outlook but in Gmail is looking pixel perfect.

Swift Digital templates are designed and tested to compensate for these quirks, but it’s always a good idea to check that your content looks neat and tidy in Outlook, too.

Emails look different across different email clients. What might look ok in Yahoo may not look right when received in Outlook. We recommend testing to a couple of different email clients to check your email is looking the same across the board. Check for broken links – Test by clicking them all, do they take you to the correct destination?

If you use Outlook as your work email which is often the case for corporate organisations, then send a test to your personal yahoo or gmail account.

Your email marketing provider will have testing tools for you to use but if you want to test your emails at a more granular level then there are a range of email testing tools out on the market that can cross-check your emails against all email clients and recent versions as well as check across popular mobile devices, tablets and desktops.

They can also cross-browser check which means they can check your emails against different browsers such as Chrome, Forefix and Safari.
