Sometimes called a “blacklist”, this is a list of customers that have unsubscribed from receiving emails.

If the customer clicks the unsubscribe link in a message and unsubscribes they will be added to this list.

You can also use the "ADD" button to add an address one at a time, or import a file:

Import unsubscribed contacts:  the file must be in a CSV format.

NOTE: When you click Choose File the system will ask you to specify the column header:

If you indicate that the column will contain the Amazon Order ID, you can also specify if it is an Amazon opt-out.  This would be used if the list is a group that has electively unsubscribed with Amazon from receiving any further emails from 3rd party sellers.


NOTE: There is one other option for unsubscribing a user, and it is a manual option.

When responding to an email from a buyer, if you want to unsubscribe the buyer from future emails there are two unsubscribe email addresses you can use:

These can be used in the bcc field in an email reply to a customer.   Doing so will trigger the appropriate Unsubscribe.

‚ÄčThe first address,, adds the customer to the unsubscribe list, and no further SellerMail emails will be sent (on either the current or on subsequent orders).  This is a more terminal option, and is used typically when a customer responds in such a way that you want to make sure they get no more communications from the automated systems in ManagebyStats.

The email address will cancel any remaining scheduled SellerMail emails only for that particular order.  This is useful for the above mentioned circumstance, when you want to stop automated emails for a particular order, but you don’t want to unsubscribe the customer from all future emails.  Sending a reply to accomplishes this.

NOTE ALSO: Rather than needing to watch for customer replies and respond quickly to remove them from future, scheduled emails, we’ve automated the process.

All you need to do is set up email forwarding, and a rule to send customer replies to  Incoming emails from your customers are then forwarded to the address, and all replying customers are automatically processed.

For example, let’s say you have a customer service email address of   You send your SellerMail emails using this email address and your customers reply to this email address.   If you go to your email service provider and set up a rule that all emails coming in to have a copy of the email forwarded to, then, when a customer sends in a reply, this rule will send a reply to the unsuborder address and automatically cancel all remaining SellerMail messages relating to that particular order.

You can then go in and reply to the customer when able, but you don’t have to worry about them getting more automated messages.

In other words … if the customer sends a reply, the above rule will ensure SellerMail stops sending any more SellerMail messages on that order.

Amazon Opted-Out Customers

Amazon has made it so customers can opt-out of receiving 3rd party communications. In most case the customer does not even realize this cuts the ability of the companies they buy from to reach them. When a customer has “opted out” and you try to send a SellerMail message, Amazon notifies you with an email:

“Your message to a buyer could not be delivered”

This means the SellerMail message did not go through. If you want to then unsubscribe that customer so SellerMail no longer tries to reach them, you can do so by forwarding that email notice from Amazon to this address:

Doing that will mark them as blocked and they will not be sent any further messages from SellerMail.

Note that you can also set up a rule with your email provider (Gmail, for example -- see below for How-To for Gmail) to automatically forward these notifications to that email. In that way these customers will be automatically unsubscribed without the need for your intervention.

Note Also: Be sure the email address you are forwarding these from is listed in the SellerMail | Settings profiles in your ManageByStats. If not, simply add it there by clicking the ‘+’ button and adding your email address there.


How To Set-up a Gmail Rule

Create a Gmail account if you haven’t already.


Set your Gmail account as the recipient of Buyer Opt-Out Emails from Amazon.

Create a profile in your MBS with your Gmail. You can disregard this step if you already have your Gmail address in an existing profile.

Create your forwarding setting from your Gmail to ManageByStats.



To: (Your Gmail address)

Subject: Your message to a buyer could not be delivered





You’re all done! This will then forward new emails that fit the criteria to us and be automatically unsubscribed in MBS.
