Klaviyo

What it does

Klaviyo combines customer marketing tools with Composer, an AI agent that can draft email, SMS, MMS and push campaigns from a plain-language brief. Composer can also draft audience segments and flow structures for review.

Who it suits

It may suit a retention marketer who wants campaign drafting and audience work inside the same customer marketing platform. Composer prepares drafts; a person must review and approve marketing content before it is sent or a flow goes live. Teams using multiple channels should check each channel’s setup and charges separately.

Pricing and limits

The free plan allows up to 250 active profiles and 500 emails per month. It lists an AI subject-line generator and $5 of Composer usage per month. The lowest paid email tier was not confirmed from the pricing page during this check, and additional Composer usage and messaging costs need review against the current plan.
