SH Consulting
Deliverability Audits and Remediation: SH Consulting performs a full diagnostic of your email program. We analyze engagement data, database health, and third-party reputation sources to produce a complete picture of your performance and sender reputation. Our audits cover triggered emails, automations, and broadcast sends. We analyze templates for conversion, review sending schedules and frequencies, and deliver insights built around your actual data, KPIs, and operating model - not generic recommendations. ‎‎ Domain and IP Strategy: Customer.io recommends separating transactional and marketing traffic onto different subdomains. We design and implement that split correctly. We optimize shared-to-dedicated IP migrations, transactional IP pool usage, and warming schedules that protect your reputation. ‎ DMARC Enforcement: We move domains from p=none to p=reject without breaking legitimate mail - including complex environments where Customer.io is one of several sending platforms on the domain. ‎ Migrations into Customer.io: Platform migrations are where deliverability breaks most often. We handle subdomain planning, authentication setup, warming schedules, and reputation transfer so your migration doesn't start with months in the spam folder. ‎ Email Security: DNS hardening, spoofing and domain hijacking protection, MTA-STS, and TLS reporting. Our security research on subdomain takeovers at MIT, Harvard, and Stanford has been covered by Ars Technica and others. The same techniques attackers use against universities are what we protect commercial domains from. ‎ Our Team: Audits and remediation are overseen by our Head of Deliverability, Luke Martinez. Luke spent a decade at SendGrid building their deliverability consulting and architecture teams, then helped build the Everest platform at Validity. We know how mailbox providers make filtering decisions because we've worked inside the platforms that send the email.
