I'm not getting my newsletters.
To ensure our newsletter get to you, please add our newsletter's "from" address to your "safe senders" or "approved senders" list. If you don't have something like that, you may need to chat with your IT folks so they can allow our messages through your mail server. For more information about our mail servers, please see the 'Mail Administrator' section below. As always, feel free to send an email to email@example.com or submit a request on our feedback page.
I am receiving multiple copies of the same newsletter.
If you are receiving two identical SmartBriefs each day, it’s probably because you are subscribed with two or more separate e-mail addresses. (Our distribution system doesn’t send multiple copies of a message to the same address.)
You can check your subscription address by looking at the “created for” information at top of your newsletter. From there, you can stop delivery to one of the addresses using the Unsubscribe link in the corresponding SmartBrief e-mail’s footer, or submit a support request if you continue to experience problems.
We’re receiving a large volume of messages from SmartBrief.
SmartBrief has the ability to throttle connections on a per domain basis, and we'd be happy to lower the connection speed and/or number of connections for your domain. Please send your request to firstname.lastname@example.org with the domain name and your full contact info.
