Polished Website & Reliable Emails

My site, https://buildin-house.com/, is up and running but still feels rough around the edges. The first headache I need solved is email: messages from the contact form either never arrive, slip into spam, or lose their formatting on arrival. I want every inquiry to land cleanly in my inbox—no bounces, no junk-folder detours, and the layout intact. While you are in the code, I also need the mobile experience tightened up for smartphones and the overall load time brought down to something users won’t notice. I’m just getting started, so please keep solutions pragmatic and budget-sensitive rather than enterprise-level overhauls. Deliverables • Configure and validate email so all form submissions are delivered, bypass spam filters, and render correctly. • Implement responsive tweaks focused on common smartphone breakpoints; tablets can follow later. • Apply sensible performance optimizations (caching, image compression, minification) that noticeably reduce page-load time without rebuilding the entire stack. I’ll consider the job done once test emails reach my Gmail and Outlook accounts flawlessly, the site scores well on a mobile-friendliness check, and initial lighthouse audits show faster load metrics. Let me know your approach, estimated timeline, and any lightweight tools or plugins you plan to use.
