Privy

Privy's onsite tools (popups, banners, spin-to-win wheels, exit-intent overlays) are its original strength and remain the main way merchants use it to grow a list before ever sending a campaign. From there, the email and SMS builder handles welcome series, cart recovery, and broadcast sends using the same visitor and customer data captured on-site.

Pricing is based on monthly site traffic rather than contact count alone, starting at $24 a month for up to 10,000 monthly pageviews on the Convert plan for list growth tools only; the Starter plan adds full email sending, and the Growth plan folds in SMS credits, with 1,500 email contacts and 1,250 SMS credits on its entry tier. SMS runs about $0.007 per message for US recipients on top of the plan price. A 15-day free trial covers the popup and email tools. It fits a store that wants to grow its list and email it from one dashboard without a heavier platform like Klaviyo.
