I think everybody will benefit from it as not only can you change the text in your own language, but you can change into your own text.
Dear friends,
We're happy to announce that an option to change the button text is added! 🎉
This is where you will find it:
Go to the widget's Settings tab
Choose Language section
Name the fields the way you need
Check out the widget and the new option in our Subscription Form online demo!
And your feedback is always welcome in the comments below 🙂
