How do I fix missing text replacements?

Let's say you want to use the replacement {{first}} in your emails, but you're finding out that some of your prospects don't have that field. Here's a reminder on how replacements work. 

There's an easy fix! Just edit your message and tweak your text replacement to include fallback text like so: {{first:there}}. This will make your message read "Hi there" for people without a first name

Alternatively, if you have multiple missing text replacements for a prospect, you can personalize their individual emails manually.
