    Experienced marketing automation specialist fluent with data modeling, automation, CRM design, systems integration and implementation. ActiveCampaign oriented 6 years and ActiveCampaign Certified Consultant 5 years. Plus another 15 years’ experience with other front office systems. Event Automation, Event Tracking, Lead Scoring, Reporting, ‘Smart Templates’ using conditional content, CRM Pipeline and Stage development, Forms development and deployment, Date Sentinels, Logic, Sorting/Segmentation to match messaging, Email Templates, and more are some of the items we have experience with and can assist on. We design and implement your events and outcomes into ActiveCampaign so to fully utilize features and functions. All development work is well documented and done in a modular fashion. Typically, we provide; • Data Dictionary • Video Development Library • Design Journal • Lucid Chart schematics If we need data from another application in the tech stack (which we can help define), we first try and use native (free) connectors, then Zapier and can provide the optional custom programming to bridge the systems via the API if needed. If ActiveCampaign is the core of your marketing automation and you experience any of the following pain points, we can help; • Cluttered and hard to manage pipelines. • Lack of metrics and attribution to measure success. • Haphazard system development work without documentation. • Inefficient data integration or data capture. • Off-the-shelf automations that lack logic and are ineffective. • Data disorganization and system entropy. If there is continued interest, please send a message and we can discuss the options. Thanks for your interest. - Steve
