Why Zap Shield Exists
Because 90% of cold email failures come from one thing:
Your reputation goes bad faster than you can fix it.
Rotating DNS Zones for Clean Reputation
Outcome: When spam checkers look up your domain, they see a clean, safe history.
Zap Shield rotates DNS zones intelligently so your domains don't "inherit" a bad neighborhood.
This prevents:
- spam-tool fingerprinting
- domain clustering
- negative DNS neighborhood scores
Why this matters:
- Spam filters judge your domain not just by you but by your neighbors.
- Zap Shield ensures your neighbors are always clean.
Blacklist Protection
Outcome: Your domains stay clean. Your campaigns stay alive.
Zap Shield continuously monitors your domains & sending patterns across major blocklists.
If something risky shows up, Zap Shield intervenes early, fixing it before it becomes a blocklist entry.
Why this matters:
- Once your domain hits a blacklist, it tanks inboxing for weeks.
- Zap Shield prevents that keeping inbox placement stable long-term.
Enhanced Deliverability
Outcome: More emails land in inbox → more replies → more revenue.
Because Zap Shield enforces stricter setups and reputation protection, users consistently see:
- 40–60% higher inbox placement
- Less spam filtering
- More consistent warmup & sending performance
Why this matters:
Better mailbox placement = more opens → more clicks → more deals closed.
Google DNS (Best-in-Class Infrastructure)
Outcome: Your domain looks more trusted to ESPs - especially Gmail and Outlook.
Zap Shield runs all domains on Google Cloud DNS, one of the fastest DNS infrastructures globally.
You get:
- Faster DNS responses
- Higher domain trust
- Better reputation signals to Gmail, Outlook & Yahoo
Why this matters: ESPs trust Google nameservers → this directly increases your inboxing probability
Dedicated Creation & Redirection IPs
Outcome: Your reputation is isolated and other senders can't hurt you.
Zap Shield uses an isolated IP pool for creating, routing & managing domains.
You are never mixed with senders who:
- blast too fast
- get blocklisted
- spam their mailboxes into the ground
Why this matters:
- Shared IPs can get poisoned fast.
- Zap Shield isolates you → gives you a predictable, safe environment to scale.
