Some of his emails never arrived anywhere. Not in the inbox. Not in spam. Gone. Weeks before a major program launch, a DNS-level audit surfaced 4 separate failures stacked on top of each other. We migrated the full mailbox to Google Workspace, rebuilt authentication from scratch, and verified delivery live in 48 hours.
The client, a UK based author and coach, came to us weeks away from launching a new program. Emails from his main address were landing in spam. In at least one confirmed case, a message vanished completely, with no bounce and no error. Replies from real people were hitting his own junk folder too. His primary email address could not be trusted to deliver a single message, and nothing inside his email tools explained why.
His mail ran on a shared hosting platform, so his sending reputation depended on every other customer using the same servers. DKIM was switched on in the control panel but never published to DNS. Gmail and Yahoo now require DKIM, so receivers were silently dropping his mail, which explained the emails that vanished without a trace. His spam filter rejected suspected messages at the server before they reached any folder, so legitimate mail was being refused and nobody knew. Everything then forwarded to a personal Gmail, which rewrites the delivery path and breaks authentication. That is why replies from real humans landed in junk. DMARC had no enforcement and no reporting, so all of this had been invisible for years.
Complete mailbox backed up before anything changed, with 1,600+ emails secured. Google Workspace set up and the domain verified. Full mail history migrated with 0 emails lost. MX records cut over from the old host to Google in a single sequenced change. Correct SPF, a 2048-bit DKIM key, and a DMARC policy with reporting published. Authentication verified live at Gmail, Outlook and Yahoo, with test messages hitting the inbox in 12 seconds.
Full audit run before touching anything. The diagnosis took under an hour and surfaced 4 separate failures: shared hosting reputation, DKIM enabled but never published, server-level rejection of legitimate mail, and forwarding that broke authentication.
Complete mailbox backed up before any change was made. 1,600+ emails secured, including 400+ legitimate messages sitting in spam that the client had never seen.
New Google Workspace account configured and the domain verified. The client moved off shared infrastructure onto a sending reputation he alone controls.
Inbox, sent, drafts and spam migrated to Workspace and reconciled against the backup, folder by folder. 0 emails lost.
MX records moved from the old host to Google in a single sequenced change, timed so mail in transit kept flowing during the switch.
Correct SPF record published, a 2048-bit DKIM key generated and published to DNS, and a DMARC policy with aggregate reporting put in place so future failures show up in reports instead of staying invisible.
Test messages authenticated and delivered at Gmail, Outlook and Yahoo. Inbox arrival in 12 seconds. 10/10 on an independent deliverability audit and no blocklist listings.
SPF, DKIM and DMARC all pass. Test messages reach the inbox in 12 seconds. The domain is not listed on a single blocklist, and the independent audit came back 10 out of 10. The full mail history survived the move down to the last message, including the 400+ legitimate emails that had been stuck in spam. The client now sends from his primary address with confidence, right on schedule for his launch. Deliverability problems rarely have one cause. This client had 4, and any single fix on its own would have failed.
10/10 deliverability. 1,600+ emails migrated. 0 lost. 48 hours start to finish.30 minutes. No pitch. Walk away with a specific diagnosis and fix plan for your setup.
