How to resolve email delivery problems

Mail-List.com delivers email discussion group messages.

The nature of how these group emails are sent can cause ISPs or Spam Filters to classify your Mailing List email as Spam or choose to block delivery altogether.

When this happens, our system sends messages to you advising of the situation.

Example message

Subject: Your newsletter is being blocked

Dear Mailing List Subscriber:

Your email hosting company blocked the following messages(s) that you signed up for:

What does this email mean?

When you receive the above message, that means emails from Mail-List.com are being blocked by your ISP.

How am I affected?

Because of the delivery problems, your Mailing List email is being "throttled", meaning we are not sending all messages to your address. We add a note at the top of new emails indicating the problem.

If your email address is rejected too many times, then your email will be removed from the Mailing List. By skipping a few emails, we give your ISP time to solve the problem.

What can I do to fix this problem?

File a support ticket with your ISP. Be sure to include the entire email we sent you with your support ticket. The email contains helpful information for your ISP.

Our email includes instructions for your ISP to whitelist all Mail-List.com IP addresses, which are listed here: https://mail-list.com/whitelist/.

My ISP solved the problem. How do I resume regular delivery?

Once the problem is fixed, you can "reset" the throttling feature.

Open a recent email from the Mailing List. Click the link at the top of the email (example below). This tells our system to resume deliveries with the next message to the Mailing List.
