Thanks for flagging this! It sounds like you're unable to change stages from within the email template, which is not expected behavior. We'll look into it for you.

In the meantime, as a workaround, you can try changing the stage manually from the pipeline view by selecting the prospect(s) and updating their stage directly there. If the automated stage change after sending an email is also not triggering, please double-check that the "Automate this Task" option is enabled and that the timing is set correctly in your task settings.

If the issue persists, feel free to share more details (such as which pipeline and template you're using) so we can investigate further!
