Sending reputation

Email providers trust a sender whose readers want their emails. Two numbers decide that trust, and we watch them for every account:

• Spam rate: spam reports as a share of emails delivered.
• Hard bounce rate: emails that couldn't be delivered at all, as a share of emails sent. A mail server refusing an email on policy grounds counts as a hard bounce. Temporary bounces, addresses we found invalid before sending, and sign-in and confirmation emails never count.

The steps

We check your last 30 days every day. If either rate crosses a line, your account moves up a step:

Step	Spam rate	Hard bounces	What happens
Warning	0.04% or more	1% or more	Your newsletters leave the leaderboard, directory and recommendations. We tell you why in the app and by email
Restricted	0.06% or more	2% or more	You can send up to 500 emails a day, and inviting or importing subscribers is paused
Sending suspended	0.08% or more	3% or more	Marketing email stops. You can still sign in, clean your list, export it and ask for a review

A single email with 200 or more deliveries can also suspend sending on its own, as soon as it reaches 0.2% spam reports or 5% hard bounces.

Small senders. If you delivered fewer than 200 emails in the last 30 days, we don't use rates. Instead, 2 spam reports in 7 days is a Warning and 4 is Restricted.

New accounts. In the 30 days after your first send, each step comes one level sooner. A single email at 0.1% spam or 3% bounces suspends sending.

A second suspension. If sending is suspended twice within 90 days, we suspend the whole workspace. You can still export your data while we review it.

Getting back to normal

• Warning clears by itself after 14 days below the warning lines.
• Restricted goes back to Warning after 30 days below the restricted lines.
• Sending suspended and a suspended workspace only end after we've reviewed them. Reply to the email we sent you to ask for a review.

How to stay clear

• Send only to people who asked to hear from you.
• Remove subscribers who bounce or haven't opened in months.
• Never send to a bought or borrowed list.
• Make unsubscribing easy. Every Noosletter email already has a one-click link.

High spam or bounce rates on an email also cost it, its author and your newsletter points. See How newsletter points and rankings work.
