This form how you can add variety to your email to target actions by allowing the supporter to choose a subject line from a drop-down list, or add their own.
We have a help centre article to take you step by step through four ways to vary the subject line in your emails to your target.
You can also add variety by encouraging supporters to personalise their messages with a direct question, as we've done here. If you're using one of our provided datasets you can add data from the dataset, such as constituency or council name to the message using tokens, or add filters for tailored messages for individuals or groups.
