1. Skinny Fizz
Challenge:
Skinny Fizz, a New Zealand beverage company stocked in major supermarkets, started 2023 with minimal email marketing infrastructure. They had just three basic automations and sent only one campaign per month. This limited approach meant they missed key touchpoints in the customer journey, no cross-selling, minimal upselling, and few opportunities for customer feedback. For a perishable product, their low repeat order rate was particularly concerning, and list growth had stagnated.
Solution:
In-box implemented a three-stage optimization strategy:
- Created in-depth automation sequences targeting each stage of the customer lifecycle
- Developed strategic pop-up forms to always add new subscribers
- Launched weekly educational campaigns that positioned the brand as an authority in health and sustainability
The team worked closely with Skinny Fizz to align all communications with their brand voice and core values. Each automation was customized to speak directly to their health-conscious audience, while campaigns balanced promotional content with valuable education about health and sustainability.
Results:
The transformation happened in just 30 days:
- Email revenue jumped by 921%
- Click rates improved by 101.49%
- Placed order rate increased by 50.16%
- Email deliveries rose by 999%
- List growth expanded by 28%
- Achieved a 337.5% return on investment

Solution:
The team implemented a comprehensive strategy focusing on three key areas. They started by creating detailed customer segments to better target their messaging. Next, they launched a series of experimental promotional campaigns to identify what resonated best with their audience.
When emails weren’t getting opened, they developed smart re-engagement automations to bring customers back. Each email was thoughtfully designed to align with their brand values while speaking directly to customer needs.
Results:
In just one year, Neurogan’s email strategy delivered remarkable results:
- Year-over-year revenue grew by 76%

Solution:
The company revolutionized their approach by implementing precise email segmentation strategies. They developed comprehensive A/B testing protocols, experimenting with everything from call-to-action buttons to email send times. A particularly innovative move was testing how removing their brand name from subject lines affected open rates, a strategy that proved highly successful.

Solution:
The team crafted a strategic lead generation campaign centered around a high-value lead magnet, “The 125 coding terms for beginners” ebook. This resource was specifically designed to attract beginners while establishing InfoShare’s expertise.

Challenge:
Good & Fugly, an Australian company fighting food waste by delivering “imperfect” produce boxes, had basic email marketing foundations, just a few standard automations like abandoned cart and welcome series. Their campaign strategy lacked sophistication, and they weren’t fully leveraging their unique mission in their communications. As a subscription-based business, they needed a strategy that could handle both one-time purchases and recurring customers.
Solution:
The team developed a comprehensive approach that touched every part of the customer journey. They built sophisticated automation flows that acknowledged different purchasing behaviors between subscription and one-time buyers.

They needed a fresh approach to present offers that would capture attention and drive action, without seeming overly promotional or diminishing their premium brand positioning.
Solution:
The company developed an innovative “forgotten discount” strategy. Instead of including promotions within regular emails, they sent follow-up emails claiming to have “forgotten” to include a Rent the Runway discount code in the previous communication.
This approach leveraged psychological principles of exclusivity and urgency while maintaining a personal, authentic tone in their communications.
Results:
This effective strategy yielded some solid results:
- Higher click-through rates compared to standard promotional emails
- Increased redemption rates for discount codes

They needed a way to generate excitement and sales before products hit their warehouses.
Solution:
They started a pre-order strategy using the email newsletter that involved opening orders a month before the release. This meant consistently promoting the offers leading up to the launch which helped create excitement and desire and incentivized fast action.
