6 Advanced Runtime Execution Modes & Sandbox

ARCHITECTURAL ADVANTAGE

Why Legacy Cold Outreach Tools Fail — And How We Solved It

A direct architectural teardown of cloud-relayed SMTP risks versus client-native browser dispatch.

⚠️ The Legacy SaaS Trap

Cloud IP Blacklisting & Dirty SMTP Relays

Most cold outreach software offers only one rigid method: direct cloud blast. You have no way to safely dry-run your template or save emails as editable drafts for manual review.

Result: Emails get flagged into Spam/Promotions tabs, domains get blacklisted, and monthly subscription bills pile up.

Email Campaign Sender provides 6 distinct operational modes tailored for different sales team workflows, compliance audits, and deliverability safety levels.

How 6 Execution Modes Operates Inside Your Webmail

Engineered for complete automation while strictly preserving human behavior heuristics.

STEP Mode 01

Direct Live Dispatch

Injects, composes, and dispatches directly from your browser webmail tab with Gaussian human pacing.

STEP Mode 02

Save as Drafts

Populates genuine drafts in your webmail Drafts folder with personalizations filled in, letting sales reps manually review and hit send.

STEP Mode 03

Stealth Jitter Pacing

Extends delay gaps (60s–180s) with simulated mouse movement and random typing cadences for maximum stealth.

STEP Mode 04

Dry-Run Simulation Sandbox

Simulates the entire campaign run in a live terminal window with zero emails actually sent—perfect for verifying variable tokens and spam scores.

STEP Mode 05

Automated Warm-Up Ramp

Starts with 20 emails on Day 1, ramping up by +15 emails daily until reaching your target sending quota.

STEP Mode 06

Business Hours Schedule

Automatically pauses delivery outside of target recipient working hours (e.g. 9:00 AM – 5:30 PM local timezone).

Frequently Asked Questions About 6 Execution Modes

Everything you need to know regarding compliance, throughput, and safety limits.

Q. Why would I use "Save as Drafts" mode?

Many SDR managers want junior reps to generate personalized emails, but have an account executive review them before sending.

Q. Does the Dry-Run Sandbox count against my Google limit?

No! Dry-Run Sandbox does not send any emails or make network requests to Google, so your sending quota remains untouched.
