Automated Event Registration & Reminder System | Zapier
Built an automated event registration system using Zapier to streamline attendee registration, confirmations, and event reminders with minimal manual work.
The workflow starts when an attendee submits a Google Form with their full name, email, phone number, company role, preferred event, session, ticket quantity, and referral source.
The submitted information is automatically formatted, added to a Google Sheets attendee database, and processed through Zapier Paths to determine the appropriate event. Based on the selected event, the workflow automatically sends a personalized confirmation email and handles the appropriate follow-up communication.
The system also includes scheduled delays for reminder emails, helping ensure attendees receive timely updates as the event date approaches without requiring manual follow-ups.
What it does:
Collects attendee information through a clean registration form
Automatically formats submitted data
Adds new registrations to the attendee database
Routes attendees based on their selected event
Sends automated confirmation emails
Schedules reminder emails before the event
Eliminates repetitive manual follow-ups
Result:
A streamlined registration system that keeps attendee information organized and ensures confirmations and reminders are sent automatically, allowing the event team to focus on the event rather than administrative follow-ups. AI-Powered Email Classification Workflow | n8n Automation
Built an intelligent email automation system using n8n that automatically reads incoming emails, classifies them by department using AI, and forwards them to the right team without any human input.
The workflow connects directly to Gmail and triggers the moment a new email arrives. A JavaScript node extracts the key email details, including sender, subject, body, and date, before passing them to an AI Agent powered by GPT-4o-mini. The AI reads the email content and classifies it into one of six departments: Sales, Customer Service, HR, Finance, Operations, or Other.
A Switch node then routes the email down the correct branch, and a Gmail node automatically forwards it to the right department inbox with a clear label in the subject line.
What it does:
Monitors a Gmail inbox in real time
Extracts and cleans email data automatically
Uses AI to classify emails by department
Routes and forwards emails to the correct team
Fully automated with zero manual sorting required
Result:
Emails that would normally sit unread or require manual sorting now reach the right department within seconds of arriving. Managed a Meta Ads lead generation campaign for a roofing and exteriors company targeting the Atlanta market, running multiple ad sets to test creative and audience performance.
Results (30-day period):
Generated 62 leads at a cost of $106.87 per lead, on a spend of $6,625.76
The top-performing ad set outperformed the industry benchmark conversion rate by 75.27%
Identified the 25-34 age group as the strongest-converting audience (0.30 conversion rate vs. 0.12 for 55-64), informing budget allocation toward that segment
Used Meta's Advantage+ Audience targeting to let the algorithm continuously refine audience delivery based on real conversion data
Creative used a mix of founder-led video content and on-site job photos, which outperformed generic stock-style ad imagery for this audience. Designed and wrote a 6-slide educational carousel for an Australian immigration law firm, breaking down what new migrants can expect across their first five years in the country — from initial settling-in to reaching permanent residency.
The goal was to build trust and engagement with a nuanced, non-legal audience by framing the immigration journey as a relatable timeline rather than a list of visa rules. Each slide covers a specific stage (getting your bearings, merging experience, stepping into growth, finding a permanent home) with practical tips, tying back to the brand's core message on evidence and long-term planning.
Published as an Instagram carousel to drive saves, shares, and DM inquiries for eligibility consultations.
