Aliases
Set aliases on entries to help find them in the search and in mentions. Free campaigns can have 2 aliases set for the whole campaign, while premium campaigns have unlimited aliases.
Defining an alias
To add an alias to an entry, navigate to that entry’s Edit form. From there, you can add any number of aliases

Each alias has a visibility option to control who in the campaign find the entry using the alias.
Mentions with an alias
When adding a mention to an entry through the alias, the alias’s name is used to render the mention.
