SendGrid & Email Deliverability Specialist — Multi-Brand Sender Infrastructure Email deliverability and sender-infrastructure expert focused on SendGrid, Mailgun, Postmark, DMARC, SPF, DKIM, return-path, DNS, dedicated IPs and multi-brand sender setups. If your emails are getting blocked by Gmail, Microsoft / Outlook, iCloud, GMX, Web.de or other mailbox providers - or your inbox placement is dropping - I diagnose the exact cause, separate symptoms from root causes, and document the exact fix. WHAT I FIX • SendGrid, Mailgun and Postmark account audits • Sender authentication: SPF, DKIM, DMARC, CNAMEs, return-path and branded sending domains • Microsoft / Outlook / Hotmail 5.7.515 authentication-level rejections • DMARC alignment failures where SPF and DKIM exist but DMARC still fails • Gmail “likely unsolicited mail” blocking and reputation issues • iCloud, GMX, Web.de, Mailcom, T-Online and DACH provider-specific blocking • Return-path / bounce-domain DNS problems, including “Domain not found” rejections • Dedicated IP setup, IP pool structure and sender separation • Multi-brand / multi-domain sender architecture • Subusers, API keys, categories, suppressions, event webhooks and tracking gaps • Transactional vs marketing send separation • List hygiene, suppression management and QA/test traffic leaking into production • Provider-aware dedicated IP warmup and sending ramp-up plans WHO I WORK WITH I work with SaaS, iGaming, fintech, eCommerce, agencies and multi-brand operators sending high-volume email through SendGrid, Mailgun, Postmark or hybrid setups connected to upstream CRMs and marketing platforms such as Smartico, Iterable, Customerio, Braze, HubSpot, Klaviyo, in-house systems and third-party platforms. I am especially useful when the issue is not obvious: SPF and DKIM look “green” but Microsoft still rejects the mail. Gmail says the message is “likely unsolicited.” A return-path subdomain suddenly fails. Clicks or unsubscribes are missing from SendGrid reports. Subusers show no volume while the parent account is sending. A dedicated IP warmup plan is needed, but the current sending path is unclear. WHAT YOU GET • A specific root-cause diagnosis with evidence, not a generic best-practices PDF • A provider-by-provider remediation plan for Gmail, Microsoft, iCloud, GMX/Webde and other major mailbox providers • Clear “do this / don’t do that” priorities • A safe sequence of fixes so you do not damage reputation by changing IPs, DNS or tracking too early • A documented audit your CTO, CRM team, ESP admin or DNS team can execute against • A practical IP warmup or ramp-up plan when dedicated IPs are part of the solution WHY I DO THIS I built and exited Optinize, a marketing-automation SaaS that delivered 3+ billion personalized messages globally and was ranked Top 20 globally by Capterra/Gartner. Before that, as CDO/CTO at a global health brand, I owned email and CRM infrastructure across the US, Europe and Israel. I have spent 15+ years operating sender systems at scale - not only writing campaigns, but managing the infrastructure behind them: authentication, DNS, sender reputation, CRM integrations, API delivery, suppressions, tracking, IP strategy and deliverability recovery. WHAT I DON'T DO I do not do generic email marketing, campaign design, social media, paid ads or “make my newsletter look better” work. I focus on deliverability, sender infrastructure, authentication, DNS, ESP setup and remediation. If that is your problem, send me your sending domain, ESP, recent rejection sample, and a short description of what changed. I will give you an initial read and tell you what I would check first.

Founder of two 7-Figure eCommerce Stores. Just starting out on Upwork. Recent win: increased sales by 41% in 2 months for a 2M/year Shopify store (same media budget). I've been in eCommerce for 15 years, my strong suit would be combining Paid ads with Email marketing, these two have to work together and then great things happen. Each business is different, I've grown stores to 7 figures with SEO only and others with paid ads. One thing in common, email always works well. Originally a Web Developer and now an all-around eCommerce Marketer. I usually like to start with an audit 1) Where can you marketing be made more efficient? 2) What can be automated? 3) Which way and how can it scale? 4) Where to put your next $$? Highly experienced in Magento, running it, growing it and surviving it. It looks like Magento may be a thing of the past, I've been mostly working with clients on Shopify and Klaviyo for email marketing. Learnt the hard way how to hire remotely and now operating a team of 10 in the Philippines for my eCommerce stores. Freelancing myself, not delegating anything for clients. I live and breath spreadsheets. Cannot imagine life without them and am capable of automating and analyzing pretty much anything with them. If you are a business owner and wished you had that expert beside you that has gone through it all and you can just consult with and pick his brain, I would love to help. Taking on interesting clients only, for hourly consulting or a flat monthly ads / email marketing fee. 60 min intro call is free so we can get to know each other, I promise to give value in the call, no strings attached.

I help businesses turn their websites into revenue-generating products — not just visually impressive portfolio pieces. For 15+ years, I’ve worked with startups and e-commerce brands, improving conversion, customer experience, retention, and overall product quality. I focus on what actually impacts business performance: clarity, trust, usability, speed, and scalable design systems. I’m not a template installer or a designer creating trendy concepts for Behance that never go live. I work on real products with real customers, real constraints, and real business goals. What I help businesses with: • Increasing conversion rates through better UX, clearer structure, and stronger product presentation. • Creating premium-looking e-commerce experiences that feel trustworthy and easy to buy from. • Improving retention through cohesive customer journeys — from landing pages to email flows. • Reducing friction in shopping experience and making stores easier to navigate and scale. • Building websites that are fast, maintainable, and designed for long-term business growth. • Turning outdated or inconsistent stores into polished, conversion-oriented products. What I can handle end-to-end: • UX/UI audits with actionable business-focused improvements. • Full website redesigns and development. • Shopify and WordPress websites from scratch. • Custom landing pages and product pages focused on sales performance. • Email templates and retention-oriented customer experience systems. • Design systems and scalable UI architecture for growing brands. • Front-end implementation with clean, lightweight code instead of bloated builders. I combine strategy, design, and development to create fast, scalable websites that look premium and perform in the real world.
