Every quarter we anonymize and publish what's actually working for African tour operators reaching US, UK, and EU travel agents. Reply rates by corridor. Subject-line patterns that land. The send day that doubles your response rate. No vanity metrics, no sales fluff — just the table.
Drawn from 4,588+ outbound touches across the Karibu cohort. Every metric is aggregated and anonymized; no tenant data is ever published.
Most tour operators selling Africa to Western agents are flying blind. You write a cold email and hope. You send on a Tuesday because someone on Twitter said Tuesday. You pitch gorillas because you sell gorillas — never knowing whether that's the hook that lands or the hook that gets you ignored.
Karibu sits on the volume to know. We see what subject lines outperform across hundreds of operators. We see which corridors reply fastest. We see the trip types that pull 1.3x ahead of the average. We're publishing it — quarterly, in plain numbers — because everyone in this industry deserves to operate with data, not folklore.
Each row reflects an anonymized aggregate across operators in the cohort. Sample size tells you how many emails or contacts the number is based on — we publish nothing below n=100.

Methodology: metrics are computed from anonymized aggregates of customer outbound activity. Reply rates count the first inbound message from a unique agent within 14 days of first send. We exclude operators with fewer than 50 sends from the denominator. Segments below n=100 are not published.
UK agents reply at 13.2% to luxury East Africa pitches. US agents reply at ~11% but the average deal value on a US-routed booking is 1.7x what we see on UK. Use UK to build a meeting pipeline; use US to fund the year.
Subjects with 5–7 words pull 1.8x the reply rate of subjects with 10+ words. Anything under 4 words reads as marketing and goes to spam. Keep it specific: a place, an agent name, a number.
Across US recipients, Tuesday morning EAT (catches end-of-Monday US morning) is the highest-reply send window. Friday afternoon EAT is the lowest. Schedule accordingly.
When you have a gorilla product, lead with it. The specificity is the hook. 'East Africa safari' as a subject pulls flat; 'Bwindi for your Audley clients' pulls.
