Pricing

Its Free plan covers 250 active subscribers and 2,500 emails per month (reduced in mid-2026). SimpleNewsletter365 keeps contacts unlimited and bills on emails sent, so storing a large list never raises your bill; Free includes 10,000 sends per month.
Deliverability and scope
MailerLite sends from its own shared infrastructure with domain authentication you set up, and offers automations, landing pages, and websites. SimpleNewsletter365 sends through your own Microsoft 365 mailbox over Microsoft Graph, from your real address and domain, and focuses on newsletters within Microsoft 365, including team roles and shared-mailbox sending.
Who each is best for
SimpleNewsletter365 suits Microsoft 365 teams that want newsletters sent from their own mailbox and domain, with pricing that does not scale with list size.
MailerLite suits small businesses and individuals who want an inexpensive, easy general email tool and are not tied to Microsoft 365.
Switching
