How can we help?

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.

Your own Microsoft 365 mailbox, using your real work address. Your newsletters are never relayed through a third-party sending service, and there is nothing new to set up.

Yes. SimpleNewsletter365 is only compatible with Microsoft 365 business subscriptions that include a mailbox. Personal Microsoft accounts are not supported.

Generally, yes. Your newsletter goes out from your own work address, the same way you send everyday email, so inboxes treat it like mail they already trust. Email sent from newsletter platforms' own servers is more likely to be filtered. This applies on every tier, including Free.

Microsoft enforces per-mailbox limits, around 10,000 recipients per day. We pace sends to stay within them and spread large sends over time, and the live send view shows exactly which batch is going out and when a paused send resumes. High-volume senders can connect more than one mailbox.

Yes. Growth adds up to 3 team members and shared mailbox or alias sending; Scale removes the seat limit. Everyone on the team shares the same access, so a group can run one newsletter together.

Automatically, and you cannot get it wrong. Every newsletter carries a working unsubscribe link, and a send is blocked if that link is missing. Opt-outs take effect immediately, including for a send already in progress, and they survive a contact being re-imported later. Each one is recorded as permanent subscriber history. Readers can unsubscribe from one type of email rather than all of them, and you can host the unsubscribe page on your own domain and write the wording yourself.

Yes, by design. Newsletters are sent through Microsoft 365 as ordinary email from your own mailbox, and a copy is filed in the sending mailbox. Your organization's existing retention policies, litigation hold, eDiscovery, and data loss prevention rules apply to newsletters the same way they apply to everything else you send. Your newsletters are never relayed through anyone else's sending servers.
