SPF · DKIM · DMARC — done for you
Your emails should land in the inbox — not in spam.
ByteShield Pro sets up SPF, DKIM, and DMARC for your store, audits your email infrastructure, and fixes deliverability issues so your campaigns actually reach your customers.
Email infrastructure secured for growing e-commerce brands.
The problem
Is your email costing you sales?
Most store owners don't find out their email is broken until revenue drops. Here are the four most common warning signs.
Your emails go to spam
Your newsletters, order confirmations, and win-back campaigns silently land in the junk folder. Customers who wanted to hear from you never do — and every campaign underperforms.
Criminals can spoof your domain
Without DMARC, anyone can send emails that look like they come from your store. Your customers get fake “your order is delayed” phishing emails with your name on them — and blame you when it goes wrong.
Gmail and Outlook show warnings
Browsers and inbox providers flag unauthenticated email with “be careful with this message” banners. That single warning destroys the trust you spent years building.
You're losing revenue without knowing it
A store sending 50,000 emails a month with a 30% spam rate is losing thousands in orders every month — while competitors with clean setups win the inbox by default.
