GTM Conversion Tracking Setup

I need a quick, clean Google Tag Manager implementation on my website so every valuable interaction is captured and reported. The essentials are:

• Contact form submissions: fire an event when a user hits “Send,” trigger an email alert to me, and log the event in my GA4 dashboard.
• Phone-to-call clicks and other key button or link clicks: record the event in GA4 and Tag Manager so I can see which pages drive calls or high-intent actions.

I already have the site live and GA4 created; you just handle the container configuration, data-layer triggers if needed, and verification that real-time events appear in the GA4 interface. A brief hand-off doc explaining the tags, triggers, and variables you used will complete the job.
