Pros & Cons
Klaviyo
Pros

- A free plan with 250 profiles and a 20 USD entry plan make it cheap to start.
- Since July 2026, SMS uses dollar-based plans with over 70 tiers, so gaps between plans are smaller and larger plans get lower per-message rates.
- A broad product suite covering reviews, helpdesk, personalization and AI agents can replace several separate tools.
Cons
- Billing by active profiles and uneven tier steps cause cost jumps, for example from 150 USD at 10,000 profiles to 350 USD at 15,000 on the Email plan.
- Many features, such as Reviews, Helpdesk, Personalization and Composer, are separately priced add-ons that raise the total bill.
