Your emails won’t book meetings if they don’t land in the inbox

Your emails won’t book meetings if they don’t land in the inbox

Deliverability at throxy is the email infrastructure we set up and run so your campaigns land in decision-makers’ inboxes, not spam. We send from separate domains that protect your main brand, rotate across more than 150 mailboxes and multiple IPs, warm every mailbox for two weeks before launch, match Google to Google and Outlook to Outlook, and test inbox placement every day. It is for B2B teams that need outbound volume without putting their main domain at risk.

Why do cold emails end up in spam?

You can have the best leads and strongest copy, but if your emails hit spam, reply rates drop to zero. Most teams never realize this is the root issue.

Most outbound systems are fragile

Most outbound systems are fragile

They rely on a single Google Workspace domain, have no warmup, no monitoring, and no fallback when inboxes get flagged. One bad mailbox can tank the entire campaign.

Spam filters keep evolving

Spam filters keep evolving

Without dynamic infrastructure, even well-written messages get caught in filters. Most teams don’t update their system fast enough to keep pace.

Generic content gets flagged

Generic content gets flagged

Sending the exact same message over and over triggers spam filters. Without message variation and warmup, campaigns get throttled before they start.

How does throxy protect your domain and sender reputation?

How does throxy protect your domain and sender reputation?

We run your campaigns across domains like trythroxy.com and getthroxy.com. This protects your core brand and isolates any deliverability issues.

Rotated IPs and inboxes scale safely

By rotating across more than 150 mailboxes and multiple IPs, we maintain deliverability while keeping volume high.

Real-time oversight

We monitor every layer of the system from domains, IPs, to ESPs to ensure nothing breaks at scale.


Multiple ESPs

We match email provider to recipient, Google to Google, Outlook to Outlook. That simple detail helps us avoid unnecessary spam triggers.

How are mailboxes warmed and rotated?

How are mailboxes warmed and rotated?

Every mailbox goes through warmup

We run a two-week warmup before launch, then keep warming in the background to build trust with email providers.

Spintax keeps messages fresh

Each message is slightly varied using Spintax logic. This avoids content fingerprinting and improves inbox placement.

Volume adjusts automatically

Our ramping engine increases or reduces send volume based on real-time inbox performance, so no single mailbox gets overused.

Mailboxes rotate and recover

When a mailbox shows signs of fatigue, we pause it and bring in a fresh one that’s already warmed and ready.

How is inbox placement monitored?

How is inbox placement monitored?

Inbox placement is tested daily

We run inbox placement tests every day to track where your emails land and optimize for better performance.

Reputation is constantly checked

We check IP and domain reputation across providers to detect early signs of issues before they affect reply rates.

Volume is managed dynamically

If a mailbox performs well, we scale it up. If it dips, we scale it down or swap it out entirely.

New inboxes are always ready

When older inboxes burn out, we deploy new ones immediately. There’s always a warm sender standing by to keep your campaigns moving.

The best messaging fails if it never gets seen
