ScaleKit

Fast-growing B2B SaaS Platform • Series A • 25,000+ users

"How a new domain nearly killed our $50K product launch — and how AutoInbox saved it"

Saved $50K Launch
52% open rate achieved

The Challenge

ScaleKit was just weeks away from launching their new AI-powered analytics feature — a $50K investment that would make or break their Series A momentum. But there was one massive problem: their new corporate domain had zero sender reputation.

Critical Issues:

  • 0% inbox placement on launch announcement emails
  • New domain triggered aggressive spam filtering
  • $50K launch investment at risk of complete failure
  • 10,000+ prospects wouldn't receive launch notifications
  • 2 weeks to fix before launch deadline

The AutoInbox Solution

We deployed a rapid-fire reputation building strategy combining our Email Warm-up Engine with technical optimization to transform their domain reputation in record time.

1

Fixed SPF, DKIM, and DMARC records for maximum authentication score
2
Aggressive Warm-up Engine (Days 2-10)
24/7 reputation building with 2,000+ warm-up emails daily across all major ISPs

Verve Style Co.

Direct-to-Consumer Fashion Brand • $50M revenue • 500K customers

"How we cleaned 100K bad emails and increased revenue by 25%"

+25% Email Revenue
98% bounce reduction

The Challenge

Verve Style's email list had grown to 500K subscribers over 5 years, but their promotional campaigns were underperforming. High bounce rates were damaging their sender reputation and wasting significant marketing spend.

Critical Issues:

  • 24% hard bounce rate on promotional campaigns
  • 100K+ invalid emails in their database
  • $85K monthly waste on sending to bad addresses
  • Declining open rates due to reputation damage
  • ISP blocking during peak sales periods

The AutoInbox Solution

We implemented a comprehensive list hygiene and reputation recovery strategy, combining our Email List Validator with AI-powered content optimization to maximize revenue potential.

1
Complete List Validation (Week 1)
Deep-cleaned 500K emails, removing 124K invalid/risky addresses

Growth Spark Digital

Digital Marketing Agency • 150+ clients • $25M managed spend

"How we saved 40+ hours monthly and achieved 100% client retention"

40+ Hours Saved
100% client retention

The Challenge

Growth Spark managed email campaigns for 150+ clients but had no scalable way to monitor deliverability issues. A single blacklisting could damage client relationships and consume hours of technical troubleshooting.

Critical Issues:

  • No centralized monitoring across client portfolios
  • 45+ hours monthly spent on deliverability troubleshooting
  • Client complaints about poor campaign performance
  • Reactive problem-solving instead of prevention
  • Lost clients due to undetected blacklist issues

The AutoInbox Solution

We implemented a comprehensive agency dashboard with automated monitoring, instant alerts, and performance optimization tools to transform their deliverability management from reactive to proactive.

1
24/7 Blacklist Monitoring (All Clients)
Automated monitoring across 50+ blacklists for entire client portfolio
2
Instant Alert System
Real-time notifications with automated remediation recommendations
3

Customer Testimonial

"AutoInbox transformed how we manage deliverability for our entire client portfolio. What used to consume hours of manual monitoring is now completely automated. Our clients see better results, and we can focus on strategy instead of technical firefighting."
