A Practical, Scalable Guide Using SMTP Relay and the Gersuz Email Marketing Platform
Sending 100,000 Emails Per Week is not about pressing a “send” button harder. It is about infrastructure, reputation, configuration, and discipline. Businesses that succeed at this level treat email as an engineered system, not a mass blast tool.
With the right setup—SMTP Relay Services like Amazon SES, proper daily sending limits, and Gersuz’s built-in Anti-Spam system and tracking system, sending and monitoring 100,000 emails weekly becomes not only possible, but sustainable and measurable.
This article explains how to do it correctly, Step By Step.

1. The Core Principle: SMTP Relay Is Non-Negotiable
If you are sending high volumes of email, direct SMTP from a single server is a dead end. ISPs simply do not trust it.
This is why professional platforms rely on SMTP relay services, such as:
- Amazon SES
- SendGrid
- Mailgun
- Postmark
These services:
- Maintain strong IP reputations
- Handle ISP feedback loops
- Scale delivery safely
- Protect you from sudden blacklisting
Gersuz Email Marketing Platform is designed to integrate directly with these SMTP relay providers, allowing you to use enterprise-grade infrastructure without managing it yourself.
2. Why 100,000 Emails per Week Is the Sweet Spot
100,000 emails per week breaks down cleanly into a safe daily sending pattern:
- ~14,000 emails per day
- ~600 emails per hour
- ~10 emails per minute
This pacing:
- Keeps ISP trust intact
- Prevents spam-triggering spikes
- Allows real-time monitoring and adjustment
High-volume success is not speed, it’s consistency.
3. Configuring SMTP Relay Inside Gersuz
Once you connect an SMTP relay (for example, Amazon SES) to Gersuz, the platform becomes Your Control Center.
Key Configuration Steps:
Authenticate Your Domain
- SPF
- DKIM
- DMARC
Assign a Dedicated Sending Identity
- Verified domain or subdomain
- Clean sender reputation
Set Hourly and Daily Limits
- Daily cap aligned with your weekly goal
- Gradual increases if the domain is new
Gersuz allows these limits to be enforced automatically, removing human error from the process.
⚠️Controlled Warm-Up Is User-Driven
Gersuz does not force warm-up behavior by default. Gradual sending logic is activated only when the user enables Warm-Up mode from the Advanced menu. This design allows professional senders with pre-warmed domains and established SMTP relay reputations to send at scale immediately, while still offering automated protection for new or cautious users who prefer a gradual ramp-up.
4. Smart Daily Distribution (The Real Secret)
One of the biggest mistakes in bulk email sending is uneven volume.
Gersuz solves this by letting you:
- Schedule campaigns in controlled batches
- Distribute sends evenly across the day
- Pause automatically if risk signals appear
Instead of “sending a campaign,” you are operating a delivery pipeline. This is how you scale without burning domains or IPs.
5. Gersuz Anti-Spam System: Protection at Scale
Sending 100,000 emails weekly without an internal Anti-Spam System is reckless.
Gersuz includes a multi-layer anti-spam engine, designed specifically for high-volume senders.
Core Anti-Spam Features:
- Engagement-based filtering (Possibility to separate low-interaction recipients)
- Automatic removal of invalid addresses
- Pre-sending content pattern analysis by artificial intelligence
This means:
- Bad data never reaches the SMTP relay
- Sender reputation improves over time
- Inbox placement stays stable
Anti-spam is not a checkbox. It’s an active defense system.
Tracking, Analytics, and Feedback Loops
At 100,000 emails per week, tracking is not optional.
Gersuz provides full visibility into:
- Delivery status
- Opens and clicks
- Bounces and complaints
- Engagement trends over time
This data feeds back into:
- Future campaign segmentation
- Sending speed adjustments
- Content optimization
The result: every week becomes smarter than the last.
Warm-Up Still Matters (Even at Scale)
If you are starting fresh:
- New domain
- New SMTP relay
- New sending identity
You must warm up.
Gersuz automates warm-up logic by:
- Gradually increasing daily volume
- Prioritizing engaged recipients first
- Protecting your domain reputation during early stages
Skipping warm-up is the fastest way to fail.
Why Gersuz Is Built for This Use Case
Many email tools are designed for “campaign sending.” Gersuz is designed for email operations.
Key advantages:
- Native SMTP relay integration
- Enforced sending limits
- Built-in anti-spam intelligence
- Scalable analytics and reporting
- Designed for long-term sender reputation
This makes 100,000 emails per week a baseline, not a stress test.
Scale Is a System, Not a Feature
Reaching and sustaining high-volume email delivery is not achieved by forcing restrictions, but by giving users intelligent control. In Gersuz, warm-up behavior is not applied by default. Gradual sending logic is activated only when the user explicitly enables Warm-Up mode from the Advanced settings. This design reflects a clear philosophy: experienced senders with pre-warmed domains and trusted SMTP relays should not be slowed down by unnecessary throttling, while newer or cautious users can intentionally opt into warm-up for protection. In practice, this means Gersuz can immediately operate at the user-defined daily and hourly limits when warm-up is disabled, or intelligently ramp up volume when warm-up is enabled. That flexibility is what turns scale into a repeatable system rather than a one-time capability. True email scalability comes from combining infrastructure, reputation awareness, and user-driven control—not from rigid platform limitations.
