I help U.S. businesses navigate SMS approval, deliverability, and compliance requirements - reducing the risk of carrier rejections, blocked traffic, and regulatory issues. I specialize in A2P SMS compliance and deliverability, including 10DLC registration, Toll-Free Verification (TFN), and TCPA/CTIA consent audits, as well as diagnosing carrier-level delivery problems. My work focuses on aligning SMS programs with current carrier and regulatory expectations so they can operate and scale responsibly in the U.S. market. If your messages are being rejected, filtered, or delayed - or you’re unsure whether your consent flow and use case will withstand carrier or legal review—I can help assess and correct the underlying issues. What I Do • 10DLC brand & campaign registration (new submissions, rejections, reclassifications) • Toll-Free Verification (TFN) setup and resubmissions • TCPA / CTIA compliance audits (opt-in flows, disclosures, opt-out handling) • SMS deliverability diagnostics (carrier filtering, content flags, throughput limits) • Platform-specific guidance (Infobip, Twilio, GoHighLevel, ClickSend, SimpleTexting) • Compliance-aware SMS automation (webhooks, triggers, rate-limiting, quiet hours)

Are you spending money on leads that go nowhere? Tired of cold callers who cannot book quality appointments? I build and run end-to-end lead generation systems for real estate investors, wholesalers, and acquisition teams across the US and I handle everything so your team can focus on closing. Over the past several years my team has generated 50,000+ motivated seller leads, booked 5,000+ verified seller appointments, and helped investors close deals across 30+ states. One client closed 14 deals in a single month from campaigns we ran. Our clients have collectively closed millions in assignment fees from leads our system produced. Here is what I deliver for your business: Motivated Seller Lead Generation: Pre-foreclosures, vacant properties, absentee owners, tax delinquent, FSBO, probate, tired landlords, and high-equity homeowners. I pull targeted data, build segmented lists, and run campaigns that reach the highest-motivation sellers in your market. Cold Calling and Appointment Setting: Trained callers using proven scripts, rapport-based conversations, daily QA-reviewed recordings, and verified appointments delivered to your acquisition team. Every call logged, every appointment documented. SMS Campaign Management: 10DLC and A2P-compliant setup, message templates tested for response, follow-up sequences, and response handling. I have maintained 100% approval rates on all A2P registrations. Campaigns typically run 15,000+ messages per day per market. Data and List Management: Targeted list pulls from PropStream, BatchLeads, and ForeclosuresDaily with motivation-layered filters. Skip tracing, list cleaning, segmentation, and CRM upload handled on our end. CRM and Pipeline Management: Full campaign tracking inside Podio, KVCore, FollowUpBoss, and REISift. Lead sheets and call recordings shared daily so you have complete visibility. Why investors keep working with my team: I run real estate lead generation exclusively. No generalist work. Every system, every script, and every campaign is built specifically for US wholesale and acquisition operations. I understand seller motivation, investor psychology, and what it takes to produce leads that actually close, not just leads that respond. My team has the capacity to handle multiple clients simultaneously. You get daily reporting, consistent output, and a team that operates as an extension of your acquisition operation. Tools my team works with every day: Dialers: CallTools, Aircall, Mojo Dialer, SmrtPhone SMS Platforms: LaunchControl, BatchLeads, REI Reply, TextMagic CRMs: Podio, KVCore, FollowUpBoss, REISift Data: PropStream, Lead Sherpa, ForeclosuresDaily, BatchLeads If you are ready to build a consistent motivated seller pipeline without managing the process yourself, let us talk about your market and what a campaign would look like for your team. Let's connect for a free strategy zoom call.

🟩🟦 PERFORMANCE MARKETING | TRACKING | FUNNELS 🟦🟩 I help businesses acquire more customers by combining accurate tracking, high-converting funnels, and data-driven performance marketing into one scalable growth system.

Most specialists manage tracking. Most CRO experts optimize landing pages. I connect all three. Instead of optimizing isolated parts of your marketing, I build an integrated acquisition system where campaigns, tracking, funnels, and conversion optimization work together. The result? ✔ More qualified customers ✔ Lower acquisition costs (CPA) ✔ Higher conversion rates ✔ Reliable attribution you can trust ✔ Better ROAS and marketing efficiency ✔ A scalable system built for long-term growth 🟩🟦 PERFORMANCE ARCHITECTURE & TRACKING 🟦🟩 Know exactly where every conversion comes from.

Optimize: Implement improvements that increase conversion rates and marketing efficiency. 4. Scale: Use accurate data to confidently increase profitable customer acquisition.

Here's a question worth sitting with: what percentage of your total revenue is email driving right now? If the answer is under 20%, you're not alone - but you are leaving real money on the table. I've seen Shopify stores doing $100K/month where email drives 8%. After 90 days working with us, that number is typically between 30-40%. Not through tricks. Through proper Klaviyo email marketing infrastructure, smart segmentation, and consistent campaign execution. That's the difference between email as an afterthought and email as your most profitable channel. My team has generated $36M+ in tracked revenue for 100+ clients across Shopify and D2C brands. We specialize in Klaviyo, and we handle the full retention channel - email flows, email campaigns, and SMS marketing - all under one roof. The problem most ecommerce brands have isn't that email doesn't work. It's that their Klaviyo setup is incomplete. Their welcome series exists but doesn't convert. Their abandoned cart flow is live but was never properly optimized. Their campaign calendar is reactive and irregular. Their SMS marketing - whether on Klaviyo SMS, Attentive, Postscript, or Omnisend - is barely being used. And nobody is watching deliverability. Every one of those gaps is revenue walking out the door. These are solvable problems. Here's how we solve them: Klaviyo Email Flows Built for Revenue We build and optimize the flows that generate passive revenue around the clock: welcome series, abandoned cart sequences, post-purchase upsells, win-back campaigns, browse abandonment, back-in-stock automations, and sunset flows. Everything is segmented by behavior and purchase history, A/B tested from launch, and optimized on an ongoing basis. This is email automation done properly for DTC and ecommerce brands - not a one-time setup that collects dust. Email Campaign Management - Done for You Consistent email marketing for ecommerce requires a real system, not a monthly scramble. We build and run your full campaign calendar: weekly sends, product launches, seasonal promotions, BFCM sequences, flash sales, VIP events, and educational content that builds long-term list engagement. You approve, we execute. That's how email stops being reactive and starts being a predictable revenue channel. SMS Marketing That Works Alongside Your Email SMS marketing is the fastest-growing retention channel for Shopify brands, and most are either ignoring it or doing it wrong. We build SMS flows and campaigns - welcome texts, abandoned cart SMS, back-in-stock alerts, promotional blasts - across Klaviyo SMS, Attentive, Postscript, and Omnisend. Integrated with email so both channels reinforce each other instead of competing. Shopify Email Marketing & Customer Retention Klaviyo's Shopify integration gives you access to behavioral data most brands never actually use. We set it up properly, build predictive segments, create flows triggered by real purchase history, and design a complete Shopify customer retention system. More repeat purchases. Higher LTV. Less dependence on paid ads. That's the goal. Klaviyo Audits, Deliverability & Optimization Underperforming on Klaviyo? We run a full audit - flows, campaigns, deliverability health, segmentation, list hygiene, and send frequency - and deliver a clear action plan ranked by revenue impact. For brands that need a reset, this is exactly where we start. Best fit: Shopify and DTC brands doing $50K+/month in supplements, fashion, beauty, pet, fitness, or food & beverage. Send me a message with your store name and where email is sitting right now - I'll give you an honest view of what's possible. Here's what you can rely on me for: These are the specific services we deliver for ecommerce and DTC brands every single week: - Klaviyo Email Marketing Strategy & Setup - Klaviyo Email Flows (All Core Sequences + Custom Builds) - Email Marketing for Ecommerce Brands - Email Marketing for DTC & D2C Brands - Shopify Email Marketing & Klaviyo-Shopify Integration - Shopify Customer Retention Strategy & Execution - SMS Marketing (Klaviyo SMS, Attentive, Postscript, Omnisend) - Email Campaign Management for Ecommerce - Klaviyo Segmentation & Behavioral Targeting - Abandoned Cart Recovery via Email & SMS - Email Deliverability & Inbox Placement Optimization - Klaviyo Audit & Revenue Gap Analysis - Post-Purchase Upsell & Retention Flows - BFCM Campaign Strategy & Full Execution - Email Copywriting & Subject Line Optimization - HTML Email Design & Template Build - A/B Testing, Flow Optimization & Monthly Reporting
