Hi there, here is everything new this month, plus a quick note on what is coming next...
Pricing that rewards growth
Stop paying for contacts you have not emailed
Most tools charge more as your list grows, even for the people who never open a thing. SimpleNewsletter365 bills on emails sent, so your whole audience costs nothing to store.
The old way
Billed by contacts
- Price climbs as your list grows
- You pay for inactive subscribers
- Cleaning your list saves money, so you hesitate to grow it
SimpleNewsletter365
Billed by sends
- Store unlimited contacts for free
- Pay only for the emails you actually send
- Grow your audience without growing your bill
Why your mailbox
Your domain already has a reputation. Use it.
Marketing platforms send from shared IPs that inbox providers treat with suspicion. SimpleNewsletter365 sends as you, from your tenant, so trust carries over, on every plan.
Send from your own mailbox
Newsletters go out through your Microsoft 365 mailbox over Microsoft Graph, from your real address and domain. Better deliverability than a shared marketing IP, on every plan.
Unlimited contacts, always
Store your entire audience at no cost. You are billed on emails sent, never on list size, so growing your list never grows your bill.
Your domain, your links
Add a custom domain for branded tracking links and short URLs that carry your name, not ours.
Delivery and click reports
See delivered, bounced, and unsubscribed for every send. Add a custom domain and get click analytics on every link.

FAQ
Questions, answered
Still unsure? The free plan needs nothing but a Microsoft sign-in.
Do you really not charge per contact?
Correct. Every plan has unlimited contacts. You pay for the emails you send each month, and Free includes 10,000 sends. Grow your list as large as you like without growing your bill.
Where do my newsletters send from?
Your own Microsoft 365 mailbox, through Microsoft Graph, using your real address and domain. There is no shared sending pool and no new identity to set up.
Do I need a Microsoft 365 business subscription?
Yes. SimpleNewsletter365 is only compatible with Microsoft 365 business subscriptions that include a mailbox. Personal Microsoft accounts are not supported.
Will my email land better here?
Sending from your own mailbox and domain generally lands better than shared marketing IPs, on every tier including Free, because recipients and inbox providers already trust your domain.
Are there sending limits?
Microsoft enforces per-mailbox limits, around 10,000 recipients per day. We pace sends to stay within them and spread large sends over time. High-volume senders can connect more than one mailbox.
Can my whole team use it?
Yes. Growth and Scale add team roles, multiple seats, and shared mailbox or alias sending, so a group can run one newsletter together.
