MailWizz | Smartlead | Instantly | PowerMTA | Postal | SMTP | Inbox Placement Email deliverability is not about sending more emails it's about sending safely, consistently, and landing in the inbox every time. With 8+ years of hands-on experience, I specialise in email deliverability and cold outreach infrastructure for businesses that need real inbox placement not warmup tool scores, not shortcuts, not guesswork. I have diagnosed and fixed deliverability problems that other consultants couldn't find. I've built cold email infrastructure from scratch domains, IPs, SMTP servers, warmup strategy — and managed systems sending millions of emails per month. When something is broken, I find the real cause. When something needs building, I build it to last.

🏆 Top Rated · 100% Job Success · 109 jobs · 7+ years · Google Cloud–certified (Professional Cloud Architect) If your emails are landing in spam, your DNS is a mess, or you’re moving to Google Workspace and can’t afford downtime — I get it fixed properly and verify it’s actually landing in the inbox. Most “SPF/DKIM/DMARC setups” stop halfway — the records exist but don’t align, so your mail still hits spam — or get flipped straight to enforcement and break your real email. I do it the right way, and I don’t stop until your mail reaches the inbox. ✅ Why clients work with me: 🏅 Google Cloud Professional Cloud Architect + Associate Cloud Engineer + Workspace Administrator certified — credentials most “email guys” simply don’t have 🎯 Top Rated with a 100% Job Success Score across 109 completed jobs 📧 Staged DMARC done right — I monitor your reports first and enforce only after every legitimate sender passes, so your real mail is never blocked 📥 I talk inbox placement, not vanity warm-up scores — verified with live headers + placement tests (MXToolbox, Mail-Tester, GlockApps, Google Postmaster) 🔁 Zero-downtime migrations to Google Workspace — from Microsoft 365, GoDaddy, Bluehost, Zoho, cPanel/IMAP — nothing lost 🌎 Fully bilingual (English / Spanish) 🛠️ What I can do for you: • Fix emails landing in spam — SPF, DKIM, DMARC with proper alignment, verified • Stage and enforce DMARC safely (p=none → quarantine → reject) for high-volume sending • Build cold-email infrastructure (Instantly, Apollo, GoHighLevel) — domains, mailboxes, auth, warm-up • Migrate your company email to Google Workspace with zero downtime • Set up Google Postmaster Tools + ongoing monitoring so you never drift back to spam ⭐ Recent reviews: “Leo was fast and knew his stuff. Great job and would definitely hire again!” “Knowledgeable and responsive. Helped me diagnose my email issue and was easy to work with.” 📩 Send me a message with your domain and I’ll tell you exactly what’s wrong with your email — before you pay me a cent.

At A Glance: Postfix
Whether it’s wishing Mom a happy birthday with a celebratory e-card or sending an urgent message to the boss, email is an important part of everyday life and an essential form of communication. An undeliverable email is a breakdown in communication, and when a critical message doesn’t reach its destination, it can send the day into a tailspin. Similarly, an inbox cluttered with potentially virus-laden spam mail causes congestion and makes a computer more vulnerable to malware or other viruses that may be contained within innocuous-looking junk messages. Postfix is a free, open-source mail transfer agent that can help protect users from potentially harmful spam mail by accepting emails only from trusted sources. Postfix runs on a variety of systems, including AIX, BSD, HP-UX, IRIX, Linux, MacOS X, Solaris, Tru64 UNIX, and other UNIX systems. Postfix is particularly useful for businesses, as it allows office users to securely communicate amongst themselves without fear of widespread damage to the network.
A Postfix SMTP server professional can assist you or your business in implementing this valuable, free tool. On Upwork, you’ll be able to browse through a global network of experts who can offer their support in a variety of ways. If you’re having trouble with an existing Postfix system, these professionals can troubleshoot the problem to quickly get you back on track. If you’re looking to install Postfix, any one of the multitude of freelancers you’ll find on Upwork’s global marketplace can help you do so. Or if you simply require help managing Postfix or navigating its features, these specialists are there to help too.
