Market Trends Overview For Financial Advertisers and Wealth Managers

2025–2030 marks a pivotal era for financial email deliverability in Hong Kong, shaped by three dominant trends:

Heightened ISP Security Measures: ISPs such as Gmail, Outlook, and Hong Kong-based providers (e.g., Yahoo! Hong Kong, Netvigator Mail) leverage more sophisticated machine learning models to detect phishing and spam, directly affecting deliverability rates.

Mobile-First Email Consumption: Over 70% of emails in Hong Kong are opened on mobile devices, necessitating mobile-optimized content and quick-loading email templates to reduce unsubscribe rates.

Trend	Key Impact on Deliverability	Priority Action
ISP Security Enhancements	Increased risk of emails marked as spam or phishing	Implement SPF, DKIM, DMARC, and monitor sender score
