A simple plugin to store Elementor Pro Form submissions
This plugin stores contact form submissions from the Elementor Pro Form Module in a handy interface on the back end of WP.
To make things even better, this plugin both notifies admin users of unread messages via a banner but also allows you to convert these contact form requests into any other post type. This means you could use a contact form to get people to submit testimonials, case studies or even front end submitted content.
It makes a simple contact form into a very versatile module indeed.
You can also export your stored contact form data to a CSV file by page submitted on or by form name (if specified in the form module).

The plugin is great! Saved life before Elementor added native form submission save, but still :)

For anyone, who facing the Critical error issue in wp-admin panel, check the count of the saved submissions. While I have 3k+ saved submissions, WP memory limit was set to 768M and it hardly handled it.
There are 3 simple solutions:
1. Delete old submissions you don't need
2. increase WP_MEMORY_LIMIT more, like: define( 'WP_MEMORY_LIMIT', '512M' ); (add or update it in your wp-config.php)
3. in the wp-content/plugins/sb-elementor-contact-form-db/sb_elementor_contact_form_db.php file in line 564 change posts_per_page to 50 instead of -1
'posts_per_page' => 50,//- 1,

Plugin slows down the admin panel -- solution inside!

DeveloperWil

If you need to prevent email addresses or entire email domains from being sent on an Elementor Form, this plugin will do that.
Stop unwanted Elementor Forms spam and create an email or domain name block list for your forms.
This is for Elementor Pro users only. This will not work with the free version of Elementor as it doesn’t support forms.
