If your wildcard is not closed properly, or contains unexpected HTML code within the wildcard, your email may suddenly appear cut off when previewing or sending it.
For example, you may have a wildcard for inserting a recipients first name into an email - which would usually look something like this: %%first_name%%
However, if you miss the last percentage symbols (e.g. %%first_name), then the wildcard is opened but never closed - causing your email to break and not render correctly when previewing or sending it. In order to correct this, add the missing %% symbols to the end to correctly close the wildcard.
If this doesn't resolve the issue, then you may wish to check the HTML code of all components that have wildcards within your email message. You can do this by opening your various text components for editing, and selecting the HTML button from the floating toolbar, as shown.
On occasions, HTML code can wrap itself around the wrong part of a wildcard. The wildcard may look fine when you're editing the message visually, but when viewing it in HTML code view, you may notice that HTML is breaking up the wildcard, as shown in the example below:
<font color="red">%</font><font color="red">%first_name%%</font>
...notice how the first % symbol is split up from the rest of the wildcard by some font colouring codes? This is causing the wildcard to 'break' and not render correctly.
To correct this, ensure the wildcard appears as one element - and is not broken up by any HTML code, as per this correct version of the aforementioned example:
