Email Marketing Strategist at WRK Marketing (2022-01 – 2025-04)

Promoted twice in under two years, from Copywriter to Email Marketing Specialist to Strategist. Managed five concurrent accounts across a roster of 20+ DTC eCommerce brands.

• Owned end-to-end Klaviyo lifecycle programs — welcome, cart and browse abandonment, post-purchase, winback, and replenishment — built on API-fed Shopify data. On one account, automated flows generated $1.03M of $1.57M in annual attributed revenue (66%) at a 3.59% placed-order rate.
• Grew monthly campaign revenue 48.9% and conversions 54.8% for a DTC apparel brand by rebuilding the calendar around wedding season instead of a single Valentine's peak, with Klaviyo driving 27.6% of total store revenue that month.
• Ran weekly A/B tests across five concurrent accounts on subject lines, offers, and send timing, measured against conversions and revenue per recipient rather than open rate.
• Analyzed 15 months of campaign data in Python to map open rate, click rate, and revenue by day and time block, surfacing underused morning and weekend send windows and resetting cadence accordingly.
• Built engagement-based segmentation (30, 60 and 90-day engaged, VIP, lapsed) with 180-day suppression rules, recovering inherited accounts from 20-30% open rates into the 40s.
• Presented monthly performance reviews to clients and coordinated creative with designers in Figma and ClickUp.

• DEN Outdoors: built the site pop-up and welcome series end to end, designing in Figma and deploying the templates, across a two-sided funnel routing homeowner leads to a builder network.
