About the client

Crust Microfinance Bank is a digital bank based in Nigeria that focuses on providing financial solutions to citizens at the personal and business levels. They provide various services such as loans, savings products, POS terminals, etc, to bridge multiple gaps in the Nigerian financial economy. They also have a foothold on the Nigerian agricultural sector, as they offer banking services to various farmers and agritech businesses across the country

Business goals

Crust Microfinance Bank was looking for an email marketing platform that had an aesthetic, simple, and easy-to-use interface, provided easy access to customer insights and the performance of their messaging, and allowed them to subscribe in the naira to easily track and review their marketing spend.

They evaluated Zoho, and they quickly realised that sending campaigns comes with a lot of restrictions, as emails have to be pre-approved, which causes delays and friction in sending campaigns.

They were also looking for a platform that enables automation and segmentation, which aids in personalizing their messaging.

They found all that and more with Circle.

How Crust uses Circle

Crust Microfinance Bank uses Circle as its primary email marketing platform. With Circle, they send periodic security and product updates, discounts, bonus services, and marketing copy to thousands of online subscribers.

With Circle, Crust Bank bridges the communication gap between its users and its products and services end-to-end, obtains real-time feedback, and educates its audience on how its products fit into their lives and businesses. It sends personalised emails to the various segments and demographics in its email list, helping it effectively nurture its customer relationships with different segments.

With simple, aesthetic templates, they stay on brand while delivering their marketing information in ways that will help them stay on top of the minds of their users. They push out a lot of engaging content on the go and can focus more on their messaging than on complex email building tools.

They also effectively measure ROI and make informed choices due to the robust analytics and reporting on the Circle platform, backed by enterprise-grade access controls suited to a regulated financial institution.

According to Roshah Idok (Communications Lead, Crust MFB):

"The Platform is beautiful, the Circle Support team is very accessible. And we can make data-driven decisions at a glance with Circle."

Frequently Asked Questions
Why did Crust Microfinance Bank switch away from Zoho?
Zoho's campaign approval process required emails to be pre-approved before sending, which caused delays and friction. Crust needed a platform that let its team move faster without sacrificing control.
Is Circle suitable for regulated industries like banking and financial services?
Yes. Crust Microfinance Bank, a regulated digital bank, uses Circle as its primary email marketing platform for security updates, product communication, and customer engagement across its retail and agritech customer segments.
Can Circle handle billing in local currency instead of USD?
Yes, Circle supports naira billing for Nigerian teams, which was one of the deciding factors for Crust, since it removed the currency-fluctuation risk that came with USD-only competitors.
How does Circle help banks personalize communication across different customer types?
Through segmentation and automation. Crust uses this to send different messaging to its personal banking customers versus its agricultural and agritech business customers, rather than one generic message to everyone.
What kind of emails does a bank typically send through a platform like Circle?
In Crust's case: periodic security updates, product updates, discounts and bonus services, and general marketing copy, sent to thousands of subscribers across different segments.
How does Crust measure whether its email marketing is working?
Through Circle's analytics and performance review data, which lets Crust's team measure ROI and make informed decisions rather than relying on guesswork.
Does switching email platforms require a lot of technical setup for a bank?
Crust's own experience suggests not: the deciding factors were ease of use and interface design, not a lengthy technical migration, and the team was able to start sending personalized, segmented campaigns relatively quickly.
