Email Deliverability Consultant

Mailchimp • Part-time

Aug 2024 - Sep 2025 • 1 yr 1 mo

As an Email Deliverability Consultant at Mailchimp, I diagnosed and resolved complex inbox placement issues for high-volume senders, marketing agencies, and SaaS platforms. My core responsibility was auditing sender reputation, analyzing authentication protocols, and implementing technical fixes restoring email open rates from spam-folder collapse to industry benchmarks. I conducted comprehensive deliverability audits encompassing SPF, DKIM, DMARC, and BIMI record analysis, IP warming strategies, domain reputation monitoring, and blacklist remediation. I managed email infrastructure for over 80 client accounts, many experiencing catastrophic deliverability drops after CRM migrations. I successfully recovered sender scores for 65 accounts, restoring average inbox placement from 12% to 94% within 30 days. My toolkit included Mailchimp analytics, Google Postmaster Tools, Microsoft SNDS, and custom scripts for bounce classification and list hygiene automation. I worked extensively with GoHighLevel users who had misconfigured sender domains, resulting in bulk emails routed to Gmail and Outlook spam tabs. I developed a proprietary 15-point deliverability checklist for CRM-integrated email systems reducing complaint rates by 60% and improving engagement metrics. My most significant achievement involved rescuing a digital marketing agency's entire email program, which had dropped from 42% open rates to 8% following a GoHighLevel migration. Through systematic DNS repair, dedicated IP allocation, and reputation warmup, I restored their program to 38% open rates within 21 days, preserving an estimated $180,000 in annual recurring revenue.

Marketing Automation Engineer

Adobe • Full-time

Sep 2022 - Jun 2024 • 1 yr 9 mos

As a Marketing Automation Engineer at Adobe, I worked within Adobe Experience Cloud and Marketo to design, build, and maintain enterprise-grade automation infrastructure for B2B technology clients. I translated business requirements into scalable CRM workflows, lead scoring models, and nurture sequences aligning marketing engagement with sales readiness. I architected automation frameworks processing over 2 million lead records annually, implementing dynamic list segmentation, behavioral trigger logic, and progressive profiling personalizing the buyer journey at scale. I managed API integrations between Adobe Experience Cloud, third-party tools, and client databases, ensuring real-time data synchronization across marketing, sales, and customer success platforms. I built custom automation rules using Marketo's engine, designed drip campaign logic based on engagement thresholds, and created dashboards tracking MQL-to-SQL conversion rates and pipeline velocity. I led the migration of three enterprise clients from legacy platforms to Adobe Experience Cloud, managing data mapping and operational continuity. I developed expertise in email authentication protocols and sender reputation management foundational to my CRM deliverability specialization. My key achievement involved redesigning a global software company's lead nurture system, reducing their sales cycle by 22% and increasing marketing-influenced revenue by $1.2 million in the first year. I also created internal training modules adopted by the broader consulting team.

CRM Automation Specialist

HubSpot • Full-time

Aug 2022 - Jun 2024 • 1 yr 10 mos

As a CRM Automation Specialist at HubSpot, I architected and optimized complex marketing automation workflows for enterprise clients migrating to integrated platforms, with primary focus on GoHighLevel ecosystem implementations. I designed end-to-end automation sequences that captured leads from paid traffic sources, nurtured them through multi-touch email campaigns, and routed qualified prospects into dynamic sales pipelines based on behavioral triggers and engagement scoring. I managed the full workflow lifecycle from client discovery and requirement mapping to technical build-out, testing, and post-launch performance monitoring. During my tenure, I successfully rebuilt over 120 broken automation workflows that were hemorrhaging leads due to platform update conflicts, misconfigured triggers, and deprecated API connections. I developed standardized workflow templates that reduced deployment time by 40% while increasing lead-to-customer conversion rates by an average of 28% across client portfolios. I spearheaded integrations of third-party tools including Zapier, Stripe, Twilio, and Mailgun into GoHighLevel sub-accounts, ensuring seamless data flow between payment processors, communication platforms, and CRM pipelines. My role required deep technical knowledge of conditional logic, tag-based segmentation, custom field architecture, and pipeline automation rules. I collaborated directly with sales and marketing teams to audit existing automation gaps, eliminate redundant sequences, and implement fail-safe triggers that prevented leads from stalling in dead pipeline stages. Additionally, I trained junior team members on GoHighLevel best practices and created internal documentation that became the agency's standard operating procedure for CRM onboarding. My achievements include reducing client churn by 35% through proactive workflow maintenance and delivering a 3x return on automation investment for mid-market SaaS clients within their first fiscal quarter.
