Best way to analyze subject lines?

[Anonymous]

Hi Marketo Community!

What do you think is the best way to analyze subject lines (without having to go back to each email to 'preview the email' then copy and past this into another document)?

Would like to analyze the performance of subject lines that perform best around a certian campaign theme. 

Thanks

Hey Amanda,

Marketo is working on a really cool subject line testing feature (I think it's supposed to be released in the next few months).

The way I currently do this is I have monthly reports I pull with all kinds of metrics and subject lines is included. We have did have to originally put subject lines into this spreadsheet but now its just adding the numbers monthly from an email performance report... pretty quick.

Hi Kim,
How did you put the subject lines into the spreadsheet?  Was this manually done?
Thanks!
