Our take
Pick Klaviyo if ecommerce / lifecycle teams who will stay on Free at $0 (250 profiles, 500 emails / month, $5 mobile, $5 Composer) while they open a first campaign, then pay the usage calculator on the same pricing page once profile count leaves the Free cap. Pick OneSignal if product teams who will stay on Free at $0 / month (3 active journeys, all channels) while they open a first Journeys canvas, then buy Growth
