The promotion was more compelling because it was based on customer segmentation and targeted content that included customer reviews and personal messages from the CEO.

Turn Me Royal — Full email funnel lifts revenue to 30%
About the company: Turn Me Royal is a unique service that turns pictures of their customers into bespoke Renaissance-style portraits.
Challenge: The business needed to create an all-encompassing email marketing plan, but first, it had to build an email list and earn customers’ trust. After this, the main challenge was segmentation and making the content relevant to different groups of clients.
Solution: Email marketing experts created a full welcome flow for the brand. The efforts were mostly focused on big sales events like Black Friday and Cyber Monday. Email campaigns were designed to target specific groups, such as VIP customers. The brand also started dynamic email campaigns to show how fun it is to give personalized portraits as gifts.
Results: Before the changes, email marketing brought nothing but a mere 5% of total income. Within the first month, this metric jumped to 15% and then settled at an average of 30% per month. The email list grew to over 25,000 people.

Eternity Modern — Automation scales to $289K/month
About the company: Eternity Modern is a furniture shop customers love for its mid-century modern sofas, high-end lighting, and wooden items.

Solution: The company made a welcome series, a cart abandonment sequence, and an upsell/cross-sell sequence, as well as 6 other email flows. Next, Eternity Modern separated the subscriber base into groups and amped up the email frequency. Moreover, the company cleaned the email list saying goodbye to uninterested and disengaged customers with a sunset campaign. Together, these strategies reduced spam complaints and made deliverability more consistent.
Results: Starting from zero, email marketing revenue grew to $80K per month in just three months, hitting $289K/month by the 11th month.
