Short answer: If you sell online in Chile, the best Klaviyo alternative depends on what you need: Isi for email, Google Ads, and Meta Ads in one place, in CLP, with local support and aligned with Law 21,719; Mailchimp for basic email; Doppler for multichannel with WhatsApp. Klaviyo is powerful but expensive, priced in USD, and English-only.
Klaviyo is one of the best-known email marketing tools, but for a Chilean SMB it comes with three concrete points of friction: it charges in USD, support and the interface are in English, and it leaves you on your own with the new data protection Law 21,719. Below, the real alternatives for the Chilean market, sorted by use case.
Quick comparison
| Tool | Language / Currency | Strong at | Best for |
|---|---|---|---|
| Isi | Spanish · CLP | Email + Google Ads + Meta Ads in one place, real measurement | SMBs that want all their marketing measured in one place |
| Klaviyo | English · USD | Advanced email/SMS for large e-commerce | Brands with a technical team and a USD budget |
| Mailchimp | English · USD | Basic email, templates | Beginners who only need to send emails |
| Doppler | Spanish · USD/local | Multichannel (Email + WhatsApp + SMS) | Anyone who needs WhatsApp marketing |
1. Isi: all-in-one, in your language and your currency
Isi measures and creates marketing for your business: it connects your store, your email, Google Ads, and Meta Ads, measures real ROAS against your Shopify (not the inflated number each platform claims), and proposes your next campaign: you approve it, Isi runs it. In Spanish, in CLP, with human onboarding, and aligned with Law 21,719. Unlike Klaviyo, it isn't just email: it's one place to see "How are we doing?" Start free, no credit card and no time limit.
2. Mailchimp: the basic option to get started
Well-known and cheap on its entry-level plan, but it falls short on advanced automation and sales attribution, and it's also in English and USD.
3. Doppler: multichannel with WhatsApp
A good option if your priority is adding WhatsApp and SMS on top of email. It doesn't manage your Google and Meta Ads campaigns or measure blended ROAS against your store.
Why not just stick with Klaviyo?
Klaviyo is very capable, but for a Chilean SMB it's more complex and more expensive than you need, and it doesn't solve Law 21,719: starting December 1, 2026, your business is responsible for how it processes customer data, and a global tool leaves you to figure out compliance on your own. The advantage of a local solution isn't being "more" than Klaviyo: it's being simpler and having your back, in your language, your currency, and your law.
Key takeaways
- The "best" alternative depends on the use case: all-in-one (Isi), basic (Mailchimp), multichannel/WhatsApp (Doppler).
- For Chile, three things matter that Klaviyo doesn't solve: CLP, Spanish, and Law 21,719.
- If you want email + ads measured in one place, an integrated local solution saves you from jumping between platforms.
Frequently asked
Does Klaviyo have a free plan?
It has a free plan capped by contacts; as you grow, the USD cost scales fast.
Does Isi replace Klaviyo?
Yes for email, and it adds Google Ads and Meta Ads measurement in one place, in CLP and in Spanish.
Do I need technical skills to migrate?
No: Isi comes with 1-on-1 human onboarding and integrates with Shopify/Justo in a few clicks.
What about my data and Law 21,719?
Isi works only with your database, doesn't train models on your information, and aligns with the Chilean law. This is not legal advice.
