Thank you for reaching out to the Community. That is a great question! We do have a survey tool available. You can click here for information on our surveys. Once you have created and published your survey, you can certainly add a link to the bottom of your email for your contacts to access.
In the meantime, if you have any further questions please feel free to reach out to us here. We are always happy to assist you in any way we can!
We do have different pricing options you can choose from. If you would like to use surveys on an individual basis, that costs $50 per use. However, we do offer the Email Plus plan, and you get many more benefits when you upgrade.
Since you have never created a survey before within your account, I have provided you a one time free use of our survey product! That way you can decide if you like it and it's right for you.
Let us know if you have any other questions, have a great day!
