Email Protection Proxies that don't get blocked.

Malicious links cloak by geo and device, and opening them from corporate IPs exposes your infrastructure and tips off the attacker. Detonate and inspect suspicious links and email content from disposable residential IPs in any region, so your security team sees what a real recipient would — without exposing the network.

Why you need proxies

Without proxies, email protection stalls fast.

Malicious links cloak by geo and device, and opening them from corporate IPs exposes your infrastructure and tips off the attacker.

Test real inbox placement

Check where mail actually lands — Primary, Promotions, or spam — by loading seed inboxes from clean residential IPs instead of your own network.

Check every provider & region

Gmail, Outlook, Yahoo, and regional providers filter differently by country. Test each from a local residential IP to see the real result.

Protect your sending IPs

Run reputation and blocklist checks through proxies so monitoring traffic never touches — or taints — the IPs you actually send from.

Monitor blocklists & spoofing

Continuously watch RBLs and scan for domains spoofing your brand, from enough vantage points to catch geo-targeted abuse.

Which proxy type

The right proxy type for email protection.

Residential IPs in the recipient's geo reveal cloaked, geo-targeted threats safely; rotate per check so nothing links back to you.

Common pitfalls

Four mistakes that hide deliverability problems.

By the time low opens show the problem, the send is over. These are the failures we see most.

Pitfall 01

Testing from your sending IP

Mail always lands in your own inbox, so everything looks healthy while real recipients get filtered.

Fix: load seed inboxes through clean residential IPs that have nothing to do with your sender.

Pitfall 02

Checking one provider

Gmail, Outlook, and Yahoo filter completely differently. Passing one says nothing about the others.

Fix: test each major provider separately — same credentials, different seed inboxes.

Pitfall 03

Ignoring region

A campaign that inboxes in the US can hit spam or a national blocklist in another country.

Fix: set -country-de, -country-fr etc. per region you send to.

Pitfall 04

No blocklist monitoring

By the time opens drop, you've already been on an RBL for days.

Fix: poll the major RBLs continuously through rotating IPs so a listing pages you the same day.
