    Through Klaviyo, a business can increase its traffic and the loyalty of customers with the use of analytics to determine the optimum email’s details, and personalization to target customers directly, raising your engagement. It’s especially useful to those undergoing expansion, with options to reach more customers and spread a brand name more successfully.

    A comparative service is SendinBlue, which also offers resources for expanding businesses to reach a wider audience. However, the design functionality and analytical center are more comprehensive, and the pricing is divided into plans, rather than your number of contacts.
