AI Email Marketing Showdown: Mailchimp vs Brevo vs GetResponse (SME Guide 2026)
Email Marketing Isn’t Dead — It Just Got Smarter
Many people assume email marketing is obsolete, but the data tells a different story. According to 2026 statistics, email marketing still delivers the highest ROI of any digital marketing channel — an average of HK$36-42 return for every HK$1 invested.
The game-changer? AI has made email marketing dramatically more effective. Automatic segmentation, smart send times, AI copywriting, predictive analytics — these features let SMEs achieve the kind of precision marketing that only large enterprises could afford before.
We tested the three most popular email marketing platforms among Hong Kong SMEs: Mailchimp, Brevo (formerly Sendinblue), and GetResponse. Here’s our comprehensive comparison of their AI features, pricing, and suitability for the Hong Kong market.

Local Payment
All three accept Hong Kong Visa/Mastercard. GetResponse also accepts PayPal.
Best Send Times for HK
- Optimal: Tuesday to Thursday, 10-11am or 2-3pm
- AI smart send time features can optimise this automatically

1,000-5,000 subscribers: GetResponse
Best value for money, complete AI features, landing pages and webinar functionality to grow your list, powerful automation.
5,000-25,000 subscribers: Mailchimp or Brevo
- If you prioritise data analytics and predictions → Mailchimp

- If cost is your primary concern → Brevo (30-50% cheaper)

Frequently Asked Questions
I’m just getting started with email marketing. Which should I pick?
Start with Brevo’s free plan. Unlimited subscribers, 300 emails per day — enough to get going. Once your list exceeds 2,000, consider upgrading or switching platforms.
Can any of these tools send both WhatsApp and email?
Only Brevo natively supports WhatsApp Business API integration. Mailchimp and GetResponse require third-party connectors like Zapier. For the Hong Kong market, where WhatsApp dominates, this is a significant advantage for Brevo.
I run a Shopify store. Which is best for e-commerce?
All three integrate with Shopify, but GetResponse has the most complete e-commerce features — including AI product recommendations, abandoned cart automation, and sales funnel tools.
How good is AI-generated email copy in Chinese?
English AI copy is already excellent across all three. Chinese copy is about 70-80% ready — you’ll need human touch-ups for tone and local expressions. For tips on improving AI output, see our guide to AI assistants.
