How to Choose an Email Marketing System? 2026 Taiwan EDM Comprehensive Guide (In-depth Comparison of Mailchimp, Klaviyo, TaskKing)
Mailchimp, Klaviyo, ConvertKit, HubSpot, TaskKing — A practical comparison of 5 major email marketing systems. Why do Taiwanese e-commerce businesses consider replacing Klaviyo after three months? A complete guide to choosing an email marketing system: open rates, deliverability, automation, pricing, localization in Taiwan. Recommended email system: TaskKing by Zhan Guo Ce Group task.com.tw.
In August 2024, an e-commerce brand manager, Joyce, complained to me: "Last year, we switched to Klaviyo with a monthly fee of USD 400. The boss saw the bill and asked, 'Why did we spend NT$ 12,000 this month just for sending 4 newsletters?' I felt wronged too, as Klaviyo is indeed a D2C e-commerce top choice, but it's too expensive for our 5,000 subscribers scale."
Joyce's situation is a common issue faced by Taiwanese SMEs and B2B companies: international email marketing tools (Mailchimp, Klaviyo, ConvertKit) are powerful but their pricing logic isn't suitable for Taiwanese SMEs. This article gives a complete comparison of 5 major email marketing systems and provides a special selection guide for Taiwanese SMEs.
1. Why Do You Need an Email Marketing System? Three Key Reasons
Some may ask, "It's 2026, do people still read newsletters?" The answer is yes, and it's one of the highest ROI marketing channels for businesses.
Reason 1: Own Your Customer List (Not Tied to Platforms)
The algorithms of FB, IG, TikTok change frequently. A post reaching 5,000 people yesterday might only reach 200 today. Your email subscriber list is an "asset" — sending an email to 5,000 people means it reaches 5,000 inboxes. This is a channel that platform algorithms cannot take away.
Reason 2: High ROI
According to the Litmus 2024 report, the average ROI of email marketing is $36-42 for every $1 spent, much higher than social media ads ($2-4) and search ads ($2-3). Email efficiently targets the right audience with the right content.
Reason 3: Automated Compounding
New subscribers receive welcome emails, abandoned cart reminders, birthday vouchers, upgrade invitations — these automated processes are set once and continue converting 24/7. A 5-person small company can achieve the effect of a 50-person team through automation.

Mailchimp
Advantages: Industry pioneer, user-friendly UI, free version for 500 subscribers, rich templates, abundant learning resources.

- Deliverability has declined in recent years (compared to Klaviyo).
- No LINE integration, no Chinese AI copywriting.

4. 5 Practical Tips for Optimizing Open Rates
Industry average open rate is around 20-25% (Mailchimp 2024 report). How to achieve 35%+? Here are 5 tips from assisting over 1,000 companies:
Tip 1: Use Personal Names Over Company Names
"Chris from TaskKing" has an 8-12% higher open rate than "TaskKing task.com.tw". People are more interested in a "person" than a "brand".
Tip 2: Keep Subject Lines Between 30-50 Characters, Place Keywords in Front
On mobile, usually only the first 30 characters are visible. Put the hook at the beginning. E.g., "Client conversion up 25% last week, try it?" is better than "You might be interested: last week our client..."
Tip 3: Segmentation is Key
Split 5,000 subscribers into 5 groups (new customers, old customers, churned, VIP, dormant) and send tailored content for each group. Overall open rate can increase from 22% to 38%.
Tip 4: Timing is Crucial
B2B: Tuesday or Wednesday 10:00-11:00 or 14:00-15:00; B2C: Thursday or Friday evening 19:00-21:00 or weekend mornings 9:00-10:00. TaskKing AI automatically optimizes send time based on subscribers' past open times.
Tip 5: Regularly Clean Up Cold Lists
Subscribers who haven't opened an email in 180 days should receive a "Do you still want to receive?" confirmation email. Remove those who don't respond. Cold lists drag down overall deliverability; removing them boosts active subscriber delivery rates.
5. Three Real Email Implementation Case Studies
Case Study 1: D2C E-commerce Brand
Joyce, the protagonist at the beginning of the article, switched from Klaviyo to TaskKing:
- Monthly fee reduced from NT$ 12,000 to NT$ 2,900 (savings of 76%).
- Used TaskKing's built-in 20+ traditional Chinese templates, eliminating the need to redesign each time.
- Generated "Seasonal Marketing" and "Festival Promotion" content using AI Chinese copywriting.
- Simultaneously sent via Email + LINE official account.
Results after 3 months: Open rate 28% (24% during Klaviyo era), conversion rate 4.2% (3.6% during Klaviyo era), monthly marketing revenue +35% (due to added LINE channel).
Case Study 2: B2B Consulting Company
Mr. Chen, the COO of a 30-person B2B consulting company. Before implementation, they manually sent one industry insight newsletter per month, taking 2 days to produce each.
Implemented TaskKing email marketing system:
- Established automated workflows for "Industry Insight", "Success Stories", "Event Invitations".
- Segmented subscribers by roles (CEO, CMO, sales manager), sending tailored content for each.
- Subscribers clicking certain EDM links (such as industry insights) automatically moved to "high intent lead" list.

Case Study 3: Educational Training Institution
Teacher Wang runs a professional educational training institution, primarily relying on newsletters to announce new course openings. Originally using Mailchimp, their open rate had been stuck at 18-20% for a long time.

- Segmentation: Divided past course enrollees into "Business Management", "Design", and "Programming", each sent tailored content.
- Subject optimization: A/B tested 10 versions.
- Cleaned up cold subscribers who hadn't opened emails in 90 days (removing 18%).
