When using conditional merge tags, you may see unwanted line breaks in the plain-text version of your campaign. You can add extra commas to prevent these line breaks.
For example, if you use the following conditional tags in your campaign:
Dear *|IF:MMERGE3|* *|MMERGE3|* *|ELSE:|* *|FNAME|* *|END:IF|*,
When you send out your campaign, your output may turn out like this:
To fix those line breaks, add extra commas into your conditional merge tags as follows:
*|IF:MMERGE3|* Dear *|MMERGE3|*, *|ELSE:|* Dear *|FNAME|*, *|END:IF|*
That should clear up those pesky line breaks.
