Several Logic Tags are used to evaluate strings and output results to the content.

| Tag | %%eval length STRING%% |

| Example | %%set strLength = "string"%% %%eval length $strLength%% |
| Results | 6 |
| Tag | %%eval lower STRING%% |
| Parameters | STRING: Variable, Custom Data, or Contact Data |
| Output | Output the defined string in all lowercase characters. |
| Example | %%set evalLow = "LOWERCASE"%% %%eval lower $evalLow%% |
| Results | lowercase |
| Tag | %%eval proper STRING%% |
| Parameters | STRING: Variable, Custom Data, or Contact Data |
| Output | Output the defined string in all lowercase characters except convert the first character of the string to uppercase. |
