About
Email security for people who'd rather run their store
The founder story
I spent years in email marketing and deliverability — building campaigns, fixing inbox placement, and managing the technical side of email for growing businesses. Over and over, I saw the same thing: good stores losing real money to problems they couldn't see.
Campaigns landing in spam. Customers receiving phishing emails sent from the store's own domain. Deliverability quietly degrading while everyone blamed “the algorithm.”
Almost every time, the root cause was the same: email authentication that was never set up properly — or never set up at all. SPF records with errors. DKIM keys missing on half the sending platforms. No DMARC, leaving the door wide open to spoofing.
ByteShield Pro exists to fix exactly that. We do one thing and we do it properly: we make your email verifiably yours, land where it should, and stay that way.
What we stand for
Transparency
You'll always know what we changed, why we changed it, and what it fixed. Every change is documented in plain English.
Practical results
We're not here to sell you security theater. We measure our work the way you do: open rates, inbox placement, and customers not getting phished in your name.
Education
We'd rather you understand your setup than depend on us forever. Everything we build belongs to you, documented, in your accounts.
