Still deciding between Constant Contact and Klaviyo?
Constant Contact and Klaviyo take different approaches to pricing and feature access. Constant Contact offers tiered plans (Lite, Standard, Premium, Multi-Account) priced by contact count, with SMS bundled into Premium ($68/month, includes 500 SMS) or available as an add-on starting at $10/month on lower tiers. Its AI copy generator is available from the entry Lite plan, and an AI campaign builder is added at Standard. Klaviyo's only documented plan is a Free tier covering up to 250 profiles, 500 emails/month, $5 of mobile messages/month, and 10,000 Composer credits for its AI subject line generator; paid tier pricing is not listed in the data available. Teams that want predictable tiered pricing, bundled SMS at scale, and automation templates should look at Constant Contact. Teams with a small contact list who want to test email, SMS, and AI features at no cost before committing budget should start with Klaviyo's Free plan and confirm paid pricing directly with the vendor before scaling up.
Compare plan limits, SMS costs, and AI features side by side based on your contact list size before you commit.
