Email and SMS marketing
Klaviyo
Email, SMS and customer data platform for consumer brands, with a free plan.
Klaviyo combines email and mobile messaging with a built-in customer data platform, and describes itself as a B2C CRM. A free plan covers up to 250 active profiles and 500 email sends a month; paid plans scale with profiles and messages. Klaviyo is listed on the New York Stock Exchange and publishes SOC 2 and ISO/IEC 27001 audit reports through its trust centre.
Where it shines
- A free plan with no monthly cost while under its profile and send limits.
- SOC 2 and ISO/IEC 27001 audit reports can be downloaded from its trust centre.
- A publicly listed company that reports its results each quarter.
Check before signing
- Free-plan emails carry Klaviyo branding, and email support ends 60 days after sign-up.
- Sending is blocked or the plan upgrades when the free limits are exceeded.
