Worth knowing

HubSpot's Marketing Hub Pro starts at ~$800/month — sticker shock is real for small teams.
Klaviyo claims its users generate an average of $85 for every dollar spent on the platform.
HubSpot connects to 1,500+ integrations via its marketplace; Klaviyo focuses on ~300 but goes very deep on e-commerce ones.
Klaviyo's predictive analytics can estimate a customer's lifetime value before they even buy a second time.
HubSpot offers 24/7 phone support on higher tiers; Klaviyo's support is email/chat only and gets mixed reviews at scale.

Klaviyo once calculated that abandoned cart emails sent within the first hour recover 3x more revenue than those sent after 24 hours — meaning your email tool's timing is literally worth money while you sleep.
