    paper Hot topics video series for NGO

    The organisation had no real video strategy. Content only happened when someone was going on TV. Engagement and follower growth were flat across all platforms. I launched the Hot Topics Video Series, the organisation’s first real go at video. In house staff on camera. Mix of live crises, field stories and big moments like the Nobel Peace Prize. Published across Instagram, Facebook, LinkedIn & TikTok. As a result, the series achieved 10.7% engagement rate on Linkedin and 13.7% on TikTok, and a 37k total reach across all 4 platforms, from 8 videos at zero production cost.

    paper Email growth strategy for NGO

    The organisation had a growing contact list but no consistent email strategy in place. Campaigns were ad hoc, open rates were declining, and email wasn’t generating meaningful revenue. I built a full email marketing flow from scratch: segmentation, dynamic content, automated donor journeys, A/B testing on subject lines, CTA buttons and send times. This drove 132% email revenue growth across 2 years, 39% open rate average, and 50% decrease of unsubscribe rate in one year.
