All the form entries submitted by visitors are stored with your website. You can view all your forms and their entries from Content - Forms. From the upper menu, you can choose between all of your forms to view entries of each form.
You can click on each entry and see the content of it as well as where it was submitted from. Also, you can download the entries as a .csv-file. For that, open that very form which entries you want to download and click on the Download button situated on the right upper corner
Voog also tries to help you out by marking truly suspicious entries as "spam". Naturally you can also delete the posts manually by clicking on the Recycle bin icon next to the entry.
But of course. For that, navigate to the page on your website where the form is located at. Click on the settings icon at the top of your form and you can see the settings view pops up. Insert your e-mail address to the field of Receive entries to email and all your future entries will be sent your e-mail address as well.
