SimpleNewsletter365 is a focused newsletter tool that sends from your own Microsoft 365 mailbox and domain.
Choose SimpleNewsletter365 if you are on Microsoft 365 and want newsletters that send as you, from your own address. Choose Brevo if you want one platform for email, SMS, CRM, and transactional messaging.

Pricing
Both tools price on sending, not on list size, so a large list does not raise your bill on its own. Brevo’s Free plan allows 300 emails per day with storage for up to 100,000 contacts, and paid plans remove the daily cap. SimpleNewsletter365’s Free plan includes 10,000 sends per month with unlimited contacts, and paid plans (Starter, Growth, Scale) raise the monthly send allowance. Compare on the volume you actually send.
Deliverability and scope
Brevo sends from its own shared infrastructure with domain authentication you set up. SimpleNewsletter365 sends each newsletter through your own Microsoft 365 mailbox over Microsoft Graph, from your real address and domain, drawing on the reputation your organization already has. Brevo’s breadth (SMS, CRM, transactional) is an advantage if you need those channels; SimpleNewsletter365 is deliberately focused on newsletters within Microsoft 365.
Who each is best for
SimpleNewsletter365 suits Microsoft 365 teams that want newsletters to send from their own mailbox and domain, with a focused, simple tool.
Brevo suits businesses that want a single platform for email, SMS, CRM, and transactional messaging, and are not tied to sending from a Microsoft 365 mailbox.
Switching
Export your contacts as a CSV from Brevo and import them into SimpleNewsletter365, where contacts are unlimited. Connect your Microsoft 365 mailbox and rebuild your recurring newsletters. Brevo-specific features such as SMS, CRM, and transactional flows do not carry over, since SimpleNewsletter365 focuses on newsletters.
