Hi, the plugin works great, thanks for your help.
I would like to customise this message that new subscribers see on the website after clicking in their email:
Congratulations! You've successfully subscribed!
Back to homepage »
I'll probably only change the text at this stage but later I may want to add other links.
Is this message set within WordPress itself or a file within the plugin? I've searched everywhere but I'm guessing you'll know straightaway.
