Alerts, activity and limits
The Overview page lists alerts and activity. Owners and admins also get each alert by email, at most once an hour for each kind.

| Alerts | A campaign paused itself; an automation switched itself off; somebody marked an email as spam; many sign-ups came from one place on a form; a daily, feed or RSS email was not sent; a plan change switched features off; a new API key was made; an app was connected. |
|---|---|
| Activity | Sign-ins and sends. Not emailed. |
Notices from the Mailfly team
We tell you about changes to the service, new features and planned work. A notice comes by email to the owners and admins, or as a blue banner at the top of your pages, or both. Press Hide to hide a banner in that browser. We may also write to you about your account; reply to that email and the answer comes to us.
If our team pauses your account (see the Terms, section 12), a red banner gives the reason, and the owners and admins get an email. Nothing is sent while it is paused. Sign-in, forms and the API still work.
