Merge Word

A combination of words referring to custom fields, which can be used for personalizing your messages. If merge words are inserted throughout the message, the brackets [ [ ] ] must be used, and the word “custom” needs to be followed by an underscore “_”. Therefore, if you have added the custom fields: industry and company name, your merge words will look like this:
[ [custom_company_name] ] is a leader in [ [custom_industry] ].
