Repair WP Contact Form Deliverability

My WordPress site is throwing up security red flags; messages submitted through the contact form never reach my inbox and sometimes even trigger spam-style warnings. The first priority is to eliminate whatever is causing those alerts and restore reliable email delivery. Once the form behaves, I’d like the entire installation—core, theme, and plugins—brought up to the latest stable versions without breaking layout or functionality.

You’ll need to trace and remove any malicious code or hidden links that might be flagging filters, configure proper SPF/DKIM records or SMTP if necessary, and hard-harden the site so future warnings don’t appear. When you finish, every test message from the contact form should land safely in my primary mailbox, no warnings attached, and the dashboard should show everything fully updated and secure.

If that sounds straightforward, tell me how quickly you can start and what information you’ll need from my hosting account to get rolling.
