Vitrazza — New welcome flow drives $564K

About the company: Vitrazza is a brand making luxurious glass chair mats.

Solution: The welcome flow was completely redesigned to include customized messages that showed off Vitrazza’s unique selling point. 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.

Results: Email sales went up by 55%, click-through rates went up by 20%, and open rates for usual campaigns and the welcome flow went over 30% and 50%, respectively. The welcome email series generated $564,200 in revenue in less than four months. The Memorial Day effort stood out from the rest of the emails and brought in over $90,000.

Key takeaway: Vitrazza’s story shows how small changes to important flows can completely change a business’s email marketing results. Customized, data-driven strategies mixed with real brand stories and smart campaigns can greatly increase online sales and keep customers interested.

About the company: Turn Me Royal is a unique service that turns pictures of their customers into bespoke Renaissance-style portraits.
