Estimates use each free plan where your subscriber count fits, otherwise the cheapest paid tier that covers your list size. Turn on the automation toggle to bump providers to their advanced automation tier. Brevo is priced by monthly email volume rather than contacts, so its cost changes with the Emails /mo input. Enter your current monthly cost to see your savings against each provider.
Independent, side by side breakdowns of the matchups merchants ask about most.
Our team can help you evaluate your options based on your subscriber volume, automation needs, e-commerce platform, and whether you need SMS marketing.
