No. WKAF uses custom database tables for forms, entries, entry meta, and email logs. — ### Does email failure affect form submission? No. Entries are saved even if email delivery fails. Email failures are logged separately. — ### Can I customize form styling? Yes. WKAF includes minimal default CSS. You can override styles using your theme or per-form custom CSS. — ### Is WKAF suitable for high-traffic websites? Yes. The plugin is designed for performance and scalability, with efficient database queries and no unnecessary asset loading. — ### Can WKAF handle large numbers of form entries? Yes. The admin entries list uses server-side AJAX pagination and loads only a limited number of records per request (10, 25, 50, or 100). This allows the interface to remain responsive even with very large numbers of stored entries. — ### Does WKAF support add-ons? Yes. WKAF is built with a modular architecture and supports add-ons for extended functionality. — ## Reviews ![](https://secure.gravatar.com/avatar/4d9e9b6095728f07c08187961152a32868956c7851deb81b0dcd0f45206dc4b9? s=60&d=retro&r=g) ### 󠀁[My new favourite wordpress form](https://wordpress.org/support/topic/my-new-favourite-wordpress-form/)󠁿 [mustafasabir12](https://profiles.wordpress.org/mustafasabir12/) March 6, 2026 1 reply THIS IS THE BEST!!! wordpress form plugin.
