National E-Commerce Brand: Product Email Marketing Case Study

Meet National E-Commerce Brand

WHO THEY ARE: A national e-commerce brand (name changed under NDA)
BUSINESS TYPE: E-Commerce
PLATFORM: Klaviyo
TIMELINE: Two years
SERVICE(S): Enhanced E-Commerce Email Package + Monthly Retainer


+289% placed order rate, plus a brand-new SMS revenue stream within 6 months.

The Challenge

The brand was sending emails, but without a strategy behind them: no segmentation, no A/B testing, and no content optimization. Email was underperforming, there was no SMS program, and the team didn't have dedicated email expertise in-house.

What I Did

  • Added audience segmentation, A/B testing, and content optimization

  • Launched SMS as a second revenue channel

  • Built targeted replenishment flows

  • Improved tracking and deliverability

  • Coordinated email and SMS into multi-channel customer journeys

In Their Words

“Besides the obvious leap in our growth KPIs, I just feel a sense of peace knowing that our email and SMS channels are handled so effectively with [Jess]. I wish I could hire Tails & Emails for all our openings; the team makes it so easy to get things done.”
- Alicia Westphal, Director of Marketing
