Suppression lists

The Suppression Lists functionality within BrotherMailer allows you to manage both suppressed contacts and domains, manage your bounce thresholds and even process your contacts against the BrotherMailer Global Suppression List.

Select Contacts from the left-hand navigation pane and then Suppression Lists from the sub-menu that appears. The Manage suppression lists screen is displayed which consist of five tabs.


Suppressed contacts

The Suppressed contacts tab displays a list of all your contacts who have unsubscribed from your communications plus those who have been automatically unsubscribed by reaching their bounce threshold or registering as an ISP Spam complainant.

You can manually add a contact to this list by clicking on the button. See Add suppressions section for more detail.

Suppressed domains

The Suppressed domains tab displays a list of all domains that have been suppressed. By adding suppression at a domain level, all email addresses in your address books for that domain are automatically suppressed. This saves you a lot of time when a company asks to be removed as a whole from your lists.

To add a new domain to this list, click on the   button. See Add suppressions section for more detail.

Add suppressions

The Add suppressions tab enables you to upload or manually add any email or domain addresses you would NOT like included in your campaign sends.

To manually add new addresses simply type the email address into the area provided ensuring you enter only one email address per line as shown in the example. Each of these email addresses will be added to your Suppressed contacts list and excluded from any future email sends.

If you wish to suppress all email addresses at one company then simply add the domain instead as shown here. Again, make sure there is only entry per line.

If you have a lot of email addresses and/or domains, you may prefer to upload a .txt or .csv file.

Use the Browse button to select the file on your computer.

You can enter an email address to be notified once the import has finished – this is particularly useful if you are uploading a large list.

Once you have entered your addresses or selected your file, click on the button. Your entries are processed and a summary report is displayed.


Regardless of the method you choose; manually entering, pasting text or uploading a file, email addresses suppressed will appear on the Suppressed contacts tab. Domains will appear on your Suppressed domains tab and any email addresses relating to those domains will appear on the Suppressed contacts tab.

Bounce thresholds

Selecting the Bounce thresholds tab displays the following screen.

A bounce threshold represents the number of consecutive times an email campaign delivery is allowed to fail due to soft bouncing, before that email address becomes unsubscribed.

A hard bounce is an email message that has been returned to you because the recipient's address is invalid. A hard bounce might occur because the domain name doesn't exist, the recipient is unknown, or there's some type of network problem on the recipient's end. The default setting is 1 and we do not recommend this setting being altered as this can affect your deliverability.

A soft bounce is an email message that gets as far as the recipient's mail server, but is bounced back before it reaches the recipient. One of the most common causes for a soft bounce is a full mailbox. This may happen with your subscribers who use free e-mail services like Yahoo and HotMail, because they allow for very little email storage. The default setting is 3 and this can be changed by either entering a new number or using the slider control. If you never wish to unsubscribe soft-bouncers then check the box next to “Never suppress soft-bouncers”.

Once you have set your thresholds, click on the button.

Global suppression list.

This function enables you to cleanse your entire contact list against the Global Suppression List. The BrotherMailer Global Suppression List is made up of hard bounces, complainants to ISPs (Hotmail and Yahoo etc.) and inbound (ie telephone) complaints, from across the BrotherMailer client accounts.

Selecting the Global suppression list tab displays the following screen.

To execute this function, click on . Your contacts are compared and the following report screen is displayed.
