Newsletters that belong in Microsoft 365
Most newsletter tools ask you to move your audience into their world: a new sending identity, a shared IP, and a bill that grows with every contact you store. We thought teams already living in Microsoft 365 deserved something simpler.
Why we built it
SimpleNewsletter365 sends through your own Microsoft 365 mailbox using Microsoft Graph. Your newsletter goes out as you, from your real address and domain, so it lands in inboxes the way your everyday email already does.
Because the marginal cost of a send is close to zero when it leaves your mailbox, we could throw out the contact tax that every other platform charges. Contacts are unlimited on every plan. You pay for the emails you actually send, and nothing else.
The result is a tool that gets out of your way: sign in with the account you already have, build your list, write, and send. No migration, no new password, no second home for your audience.
What we believe
Principles
You are the sender
Your newsletter should come from you, your address, your domain, your reputation. Not a shared marketing IP you do not control.
Pricing that rewards growth
We charge for the emails you send, never for the size of your list. Growing your audience should never feel like a liability.
Quiet by design
No bloated builder, no dark patterns, no feature you have to fight. Clear labels, calm screens, and the shortest path to a sent newsletter.
Your data stays yours
We keep Microsoft tokens server-side, isolate every account, and log identifiers instead of content. Privacy is the default, not a setting.
Send your next newsletter as yourself
Free includes unlimited contacts and 10,000 sends a month. No card required.
