Google Workspace Email Authentication (SPF/DKIM/DMARC)

Portfolio project
Corwin Ott
A home-services company in North Carolina had a critical problem: a previous developer moved its website to a new host, changed the DNS, and left without handing over any credentials. Every incoming business email was bouncing.
What I did: recovered access to the domain and DNS and fixed mail routing so Google Workspace email worked again. Then I migrated the WordPress site (files, database, themes, plugins and media) from Hostinger to SiteGround, so hosting and DNS now live in one account the owner controls.
Verification: nameservers, MX, SPF, DKIM, DMARC, site verification records and www were all checked after the move and confirmed working. The site files and database were removed from the old host.
Result: email restored, the site running on the new host, new admin access handed to the owner, and full backups of both the old and new WordPress installs.

Set up MX, SPF, 2048-bit DKIM and DMARC for Google Workspace in Namecheap. Every check passed, and the website records stayed untouched.
