.read has also been deprecated, but bear in mind it returns 3 values, you have to get the .value an example shown here:

> [@Problem adding variable in email body](http://forum.inductiveautomation.com/t/problem-adding-variable-in-email-body/45846/2):
>
> value = newValue.value if value == 1: variable = system.tag.read("[default]TagTest") variableQV = variable.value body = "TagTestValue: " +str(variableQV) system.report.executeAndDistribute(path="MyPath", project="MyProject", action= "email", actionSettings = {"to":["myEmail"], "smtpServerName":"EmailSetting", "from":"myCompany", "subject":"MySubject", "body":body})

but as you are on ignition 80/81 you should use the new functions [system.tag.readBlocking - Ignition User Manual 8.0 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC80/system.tag.readBlocking)
