Rising Talent
Project details
Most companies "play" with AI; I build revenue engines. As a Fractional CAIO and former CDO, I bridge the gap between AI hype and measurable business ROI.
I am the architect behind ChiefWizard.AI and PeakIQ.ai. I deliver production-grade systems that turn raw data into automated decisions. My experience is backed by proven enterprise results:
17x Revenue Growth: Led digital transformations scaling revenue from $200K to $5.5M .
Massive Scale: Architected systems handling 3 billion+ messages for global brands .
Proven ROI: Deployed "Decision Agents" saving $500K annually in operational costs .
Using my GROW methodology, I conduct a deep-dive audit of your tech stack and data readiness. I don't just find "use cases"; I design an AI workforce. By applying HBS Negotiation Mastery principles, I ensure your multi-agent systems reach deterministic, hallucination-free outcomes.
I bring the discipline of an Ironman athlete to your roadmap—relentless focus, endurance, and flawless execution. Let's stop experimenting and start scaling.

Bee IT Apollo subdomains remediation
Itai was a great support for our Apollo setup and email infrastructure work. He helped us with the triage and mapping of our Apollo configuration, with a strong focus on subdomain remediation and improving the overall setup for sending domains and mailboxes.
His work covered key technical areas including SPF, DKIM, and DMARC implementation, DNS record configuration and checks across MX, A, CNAME, and TXT records, as well as troubleshooting authentication and deliverability issues. He also supported us in monitoring domain reputation, reviewing email deliverability health, and reading and interpreting DMARC reports.
What stood out most was his structured approach, clear communication, and ability to quickly understand the problem, map the right priorities, and guide us toward practical fixes. Itai was reliable, knowledgeable, and very easy to work with throughout the process.
We would highly recommend him to any team that needs hands-on support with Apollo, sending domain setup, mailbox configuration, DNS remediation, and email deliverability.

DMARC Setup Support in Apollo
Itai helped our company a lot to stabilize massive Apollo challenges, triaging all potential challenges step-by-step, and delivered solutions above our expectations way ahead of milestone deadlines. Great communicator and tech expert - we would proceed working with him as the initial part of our need was just a part of a broader deliverability and mailbox/domain project that will remove all the bottlenecks and challenges we were facing in previous years. Warmest recommendation!

About Itai
Email Deliverability Expert | SendGrid, DMARC, Sender Authentication
Ariel, Israel - 5:11 pm local time
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.
