🥇 Top 1% Upwork Email Deliverability Expert
Hey, I'm Pavel. I fix broken email deliverability for SaaS, newsletter publishers, and e-commerce teams and I keep it fixed. When your emails stop hitting the inbox, you lose revenue. I stop the bleeding.
Gmail Postmaster shows Low domain reputation. A provider is throttling your sends. A migration broke your onboarding flow and nobody knows why.
These are not mysteries. They have causes, and those causes show up in the telemetry.
I diagnose what actually went wrong and fix it. No guesswork, no speculation just headers, logs, and bounce data that point to the answer.
How I Work:
I find the exact failure point using raw signals: authentication records, Postmaster data, complaint rates, bounce behavior, and recipient engagement. If it is urgent, I can usually diagnose the issue the exact same day.
What I Handle:
Emergency recovery for Google Postmaster sender reputation and blacklists
SPF, DKIM, DMARC, and BIMI setup and strict alignment
Authentication fixes after migrations or DNS changes
Deliverability audits and inbox placement testing for Gmail, Outlook, and Microsoft 365
Domain and IP warmup strategies for new sending infrastructure
Cold email setup that isolates and protects your main corporate domain
Configuration and troubleshooting for SendGrid, Mailgun, Amazon SES, Klaviyo, HubSpot, and Brevo
Fractional Deliverability Support:
Deliverability is not a one-time fix. Reputation drifts, volumes change, and mailbox providers constantly shift their rules. I work with a small number of clients on an ongoing, fractional basis to monitoring your authentication and sending health so problems are caught before they cost you money.
The Proof:
10+ years focused 100% exclusively on deliverability.
60 completed projects on Upwork, all 5-star reviews.
Author of a weekly newsletter on inbox placement strategy.
Let's Fix It:
If something is broken right now, tell me what changed, what you are seeing, and which platform you are on. Message me your domain and a screenshot of what Postmaster is showing, and I will tell you exactly what is wrong and how fast we can fix it.

Most brands think they have an email marketing problem. In reality, they have a customer journey problem. I help solve that by building Klaviyo retention systems that turn customer behavior into repeat purchases, stronger loyalty, and predictable revenue.
I'm a Klaviyo Email Marketing Expert helping Shopify and eCommerce brands increase email-attributed revenue through advanced automation, lifecycle marketing, strategic segmentation, conversion-focused email design, and revenue-driven campaigns.
I don't just build flows or send newsletters.
I build retention systems that recover lost revenue, increase customer lifetime value, improve deliverability, and create customer journeys that continue generating revenue long after they're launched.
How I Help eCommerce Brands Grow
✔ Recover abandoned revenue with high-converting Klaviyo Flows
✔ Increase repeat purchases through lifecycle marketing
✔ Improve customer retention and lifetime value
✔ Build advanced audience segmentation based on customer behavior
✔ Optimize deliverability, list health, and sender reputation
✔ Design beautiful, mobile-first email templates in Figma
✔ Build scalable email and SMS systems that grow alongside your business
Klaviyo Flows I Build & Optimize
• Welcome Series
• Abandoned Cart
• Abandoned Checkout
• Browse Abandonment
• Post Purchase
• Customer Winback
• Replenishment
• Cross-Sell & Upsell
• Review Request
• VIP Customer Flows
• Sunset & Reactivation
• Birthday & Anniversary Flows
Every flow is built using optimized trigger logic, advanced segmentation, behavioral targeting, proper timing, dynamic content, and persuasive copy to maximize conversions throughout the customer journey
Klaviyo + Shopify Setup
I ensure your email marketing ecosystem is built correctly from the start.
✔ Complete Shopify & Klaviyo Integration
✔ Event Tracking
✔ Customer Properties
✔ Dynamic Product Blocks
✔ Advanced Segmentation
✔ Signup Forms & Popups
✔ Email Authentication (SPF, DKIM & DMARC)
✔ Deliverability Optimization
✔ SMS Automation
Email Design (Figma)
Your emails shouldn't just look beautiful.
They should convert.
I design clean, premium, mobile-first email templates inside Figma before building them inside Klaviyo with reusable sections your team can easily update.
Every design balances branding, readability, conversion psychology, and user experience.
My Process
Before making recommendations, I audit your account to identify:
• Revenue leaks
• Underperforming flows
• Segmentation gaps
• Deliverability issues
• Automation opportunities
• Customer journey friction
Then I build a strategy based on your brand goals—not generic templates.
Why Clients Hire Me
Most freelancers focus on tasks.
I focus on revenue.
That means looking beyond open rates and clicks to measure what actually matters:
✔ Email Revenue
✔ Revenue Per Recipient
✔ Flow Performance
✔ Customer Lifetime Value
✔ Repeat Purchase Rate
✔ List Growth
✔ Deliverability
✔ Customer Retention
Every optimization is made with one objective:
Help your email channel become one of your most profitable revenue sources.
Brands I've Worked With
I've helped Shopify and eCommerce brands across the beauty, skincare, wellness, fashion, food, and lifestyle industries build profitable email marketing systems, including:
• Asili Skincare
• Eye Essentials
• Nordic Mylk
• GAYA
…and several fast-growing Shopify brands focused on scaling retention and customer lifetime value.
What You Can Expect
✔ Strategic Thinking
✔ Clear Communication
✔ Fast Execution
✔ Attention to Detail
✔ Ownership
✔ Reliable Delivery
✔ Data-Driven Optimization
✔ Long-Term Partnership
I treat every account as if it were my own business. My goal isn't simply to complete projects—it's to build email marketing systems that continue generating results month after month.
If you're looking for someone who understands Klaviyo, Shopify, retention marketing, email design, automation, lifecycle strategy, and revenue optimization, I'd love to learn more about your business.
If your goal is to make email one of your most profitable revenue channels not just another marketing task: I'd love to help make that happen.

Most businesses don't have a lead generation problem — they have a follow-up problem. I'm a GoHighLevel (GHL) Expert, CRM Automation Specialist, and AI Automation Consultant who fixes exactly that: slow response times, missed appointments, disorganized pipelines, and broken workflows that let leads slip through the cracks instead of becoming customers.

I work with marketing agencies, real estate companies, healthcare providers (dental practices, medical spas), home service businesses (roofing, HVAC, plumbing, solar), coaches, consultants, insurance and mortgage professionals, law firms, SaaS companies, and local service businesses — helping each capture more leads, improve follow-up speed, increase conversion rates, and eliminate manual busywork.
My Expertise Includes:
✔ GoHighLevel CRM Setup, Optimization & Cleanup
✔ Advanced GoHighLevel Workflows & Automations
✔ Lead Generation Funnels & Sales Funnel Builds

What Clients Typically Hire Me For:
Building complete lead generation and appointment-setting systems

Organizing and optimizing CRM architecture
Designing high-converting funnels and landing pages
Implementing AI-powered customer journeys (chatbots, voice agents, follow-up)
Building reporting dashboards and attribution systems
Cleaning up broken workflows and messy GoHighLevel accounts
Migrating CRMs (HubSpot, Salesforce, Zoho) into GoHighLevel
Setting up white label / SaaS Mode for agencies reselling GoHighLevel
Integrating third-party platforms using APIs, Webhooks, Zapier, Make, and N8N
Improving lead response times, conversion rates, and operational efficiency
My Approach
I start by understanding how your business generates leads, qualifies prospects, books appointments, closes sales, and retains customers. Then I design automation systems around those real processes using GoHighLevel, N8N, Make, AI tools, and custom integrations — not a generic template. The result is a scalable system that improves lead tracking, pipeline management, customer communication, reporting, and overall business performance, while reducing manual work for your team.
