INBOX INFRASTRUCTURE

All Your Sending Inboxes. One Control Center.

Scale outreach volume safely without managing dozens of separate logins and dashboards.

Connect Any Provider

Google Workspace over OAuth; Microsoft 365, Amazon SES, Elastic Email and any other host over SMTP, with the right port and TLS preset already filled in.

Automated Sending Limits

Set per-inbox daily limits (e.g. 40 emails/day) and randomized sending delays to mimic natural human behavior.

Continuous Deliverability Health

Real-time monitoring of SPF, DKIM, DMARC, and custom tracking domains to keep mailboxes healthy.

Domain Protection & Isolation

A campaign auto-pauses once its bounce rate passes your threshold (2% by default), and an inbox is pulled from rotation on its own when hard bounces and complaints drive its health score down.

INTELLIGENT ROTATION

Distribute Outreach Automatically

Outtricks smoothly balances email dispatch across all active inboxes to maximize deliverability.

PERFORMANCE METRICS

Know What's Driving Replies

Every campaign reports the same figures, computed from its own send and event log — not from a sample or an industry average.

Sent & delivered

Per campaign, per step and per sending inbox.

Opens & clicks

Tracked through your own verified tracking domain.

Replies

A reply ends that prospect's sequence and lands in the Master Inbox.

Bounce rate

Classified from the bounce mail itself, and the trigger for auto-pause.

OPERATIONAL CONTROLS

Built for Reliable Outbound Operations

Intelligent safety rails engineered to safeguard your sending infrastructure.

Ramp-Up Scheduling

Set a target daily volume and a ramp length (30 days by default); the inbox's enforced ceiling climbs to the target over that window.

Threaded Follow-ups

Ensure all follow-ups stay within the same email thread for natural context and higher engagement.

Bounce & Spam Detection

Inbound bounce mail is parsed and classified, hard bounces suppress the address, and the campaign auto-pauses once the bounce rate passes your threshold.

Timezone Smart Delivery

Schedule emails to arrive during your prospect's local business hours (9:00 AM – 4:30 PM).
