For 20 years, I've been obsessed with one thing: making sure every email and text message actually lands in the inbox, not spam, not promotions, not blocked entirely. If your emails are going to spam, your open rates are dropping, or you're building your sending infrastructure from scratch, I can fix it. Here's what I do: EMAIL DELIVERABILITY - Set up proper domain authentication (SPF, DKIM, DMARC) so your emails don't get flagged - Warm up new IPs and domains from scratch, the right way - Fix inbox placement issues: promotions tab, spam folder, bounces - Manage list hygiene and sender reputation so your deliverability holds long-term - Dealt directly with Yahoo, Hotmail, and Apple to get IP blocks lifted SMS DELIVERABILITY - Set up SMS/text systems for reminders, follow-ups, and customer replies (Twilio, Infobip, and similar platforms) - Fix carrier filtering issues and compliance problems - Build email and text sequences that run themselves, without dropping deliverability PRIVATE EMAIL SERVERS - Build and manage your own dedicated mail servers: your own IP, your own infrastructure, fully under your control - Set up business email systems you fully own, instead of renting from expensive monthly SaaS platforms - Full setup from scratch: server provisioning, DNS, SSL, security, done right the first time 20 years of hands-on experience with email infrastructure, DNS, sender reputation, and everything standing between your message and the spam folder. Let's talk about what's landing in spam, and fix it.

When something on your site, email, or infrastructure is broken or compromised and nobody can tell you why, that's the work I do. I'm a solo cybersecurity and web infrastructure consultant with 10+ years of hands-on experience...a forensic troubleshooter for web, email, DNS, ad-account, and access-control failures. Whether it's a hacked site, marketing or transactional email that won't reach the inbox, or systems behaving in ways nobody can explain, I trace problems back to their root cause rather than patching symptoms. Most of my clients are small business owners who've already tried the obvious fixes and need someone who can actually dig into the details. I work directly on the systems( WordPress, Shopify, WooCommerce, custom application stacks, and self-managed VPS environments on) rather than handing the work to a third party. That's a deliberate choice...I own the work end to end. Where I'm usually brought in: - WordPress malware removal and incident response — SocGholish/FakeUpdates, Magecart skimmers, SEO spam injection, card-testing and form-spam attacks - Email deliverability and authentication — SPF, DKIM, DMARC, MTA-STS, and inbox-placement diagnosis across Gmail, Microsoft 365, and others - Managed VPS hosting, migrations, and performance — Nginx, PHP-FPM, MariaDB, Redis, Cloudflare, CrowdSec, plus plugin audits, cache conflicts, and production-cutover validation - DNS configuration and forensics - Ad-account and access-control investigations — Google Ads/MCC compromise, click and lead fraud, tracking abuse, rogue or retained admin access, and OAuth/login review - Shopify and hosted-platform security — malicious redirects, third-party app and script review, blacklist and false-positive diagnosis Where it matters, I turn messy logs and partial evidence into a formal post-incident report you can hand to an insurer, agency, vendor, or counsel, so not just a fix but a defensible account of what happened and why. You'll get clear explanations written so you can actually follow them, documentation of what was done, what to watch for going forward, and anything else you'd want or need. I'd rather you walk away understanding your own systems than dependent on me.

Email Marketing Automation & B2B Lead Generation Specialist | Boost Your Outreach & Protect Your Domain Stop sending emails to invalid addresses. Start filling your calendar with qualified meetings. Most lead gen freelancers just scrape a spreadsheet and call it a day. That’s why your bounce rates are high, your domain reputation is suffering, and your sales team is chasing dead ends. I don’t just build lists; I engineer outreach-ready pipelines that protect your domain and drive replies. I specialize in building hyper-targeted B2B datasets with a focus on data integrity and cold email deliverability. My workflow ensures you are talking to real decision-makers who are actually looking for solutions like yours. The Problems I Solve for You: 1. High Bounce Rates: I use multi-layered verification to ensure <1% bounce rates. 2.Poor Data Quality: No generic "info@" emails. I target specific decision-makers (C-Suite, VPs, Heads). 3. Wasted Time: You get a clean, structured CSV/Sheet ready to import into your tools (Instantly, Smartlead, Lemlist) immediately. 4. Domain Blacklisting: I segment lists by domain health to keep your sender reputation safe. ⚡ How I Work (The "Inbox-First" Approach) 1. Precision Prospecting (ICP Matching) I don’t guess. I use a data-driven approach to find your Ideal Customer Profile. Tools: Apollo io, LinkedIn Sales Navigator, Google Maps, Custom Databases. Filters: Industry, Revenue, Tech Stack, Headcount, Location, and specific triggers (funding, hiring). 2. Advanced Verification & Enrichment Before a single email is added to your list, it passes a rigorous check. Syntax & MX record checks. SMTP validation (catch-all detection). Enrichment with direct emails (not generic ones) and company metadata for personalization. 3. Campaign-Ready Formatting I deliver data that works with your stack. Structured for Instantly, Smartlead, Lemlist, Mailshake. Custom fields for dynamic personalization (e.g., First Name, Company Pain Point, Recent News). Clean CSV/Google Sheets with zero duplicates. My Tech Stack: Sourcing: Apollo io, LinkedIn Sales Nav, Crunchbase, BuiltWith. Verification: NeverBounce, ZeroBounce, MillionVerifier. Outreach: Instantly.ai, Smartlead, Lemlist. Data: Advanced Excel/Google Sheets, Airtable. Industries I’ve Served: SaaS, Real Estate, Marketing Agencies, Fintech, Healthcare, and E-commerce. Why Clients Hire Me: 1. Accuracy First: I prioritize quality over quantity. A list of 500 verified leads is better than 5,000 bad ones. 2. Fast Turnaround: I respect deadlines and keep communication transparent. 3. Results-Oriented: My goal is to help you book meetings, not just send emails. Ready to Scale Your Outreach? Don't let bad data kill your campaign. Send me a message with your ICP details (Industry, Role, Location), and I’ll send you a free sample of 10-20 verified leads so you can see the quality difference. Let’s get your inbox full of qualified leads
