Sometimes specifying who is getting your mail merge campaign is just as important as specifying who should NOT get your mail merge campaign…thanks to our new Suppression Lists feature, now you have even more control of exactly who does and doesn’t get your emails.
Any email address on the suppression list will be filtered out of the current campaign.
To set a suppression list for a campaign, just select the past campaigns whose recipients you want to eliminate from your current campaign. Each past campaign in your account can be used as a Suppression List, meaning you don’t create a Suppression List separately from campaigns.
You can select a single campaign or multiple campaigns from the dropdown. Use the CTRL key on Windows or the Command key on a Mac to select multiple lists from the Suppression select box.
Any email address that was part of the chosen campaign will be suppressed, or eliminated from, this current campaign.
When do Suppression Lists come in handy?
Let’s say you’re using GMass to invite 100 people to a party. You create a Google Docs spreadsheet with your 100 invitees. You then send a GMass campaign to the people on this spreadsheet.
The next day, you realize you forgot to invite 5 of your friends. Oh no, how can you easily re-send your invite to just those 5 missing friends?!
You could just add the 5 email addresses to your master spreadsheet, use the GMass spreadsheet button to connect to the whole sheet and send to the same list, but then the first 100 people will get the same email again, making you look sloppy. If you use yesterday’s campaign as your Suppression List, however, then only the 5 new people will receive the email.
Another use might be if you’ve collected a do-not-send list over time, and want to ensure that a particular campaign doesn’t go to anyone on this list. You could add your do-not-send list to your Unsubscribe List, but that would prevent them from getting any future email campaign from you, and you may just want to use your do-not-send list on this one particular email campaign. In that case, you can create a manual Suppression List.
To manually create a Suppression List:
Since Suppression Lists are simply the email addresses tied to your past campaigns, you can create a “fake” campaign that won’t actually send but will hold the addresses you wish to suppress. To do so:
- Enter the suppression addresses in the To field of a new Compose window. Alternately, if you have a large number of email addresses, consider putting them in a Google Docs spreadsheet and then using GMass to connect to the spreadsheet.
- Enter a name for your Suppression List as the Subject.
- Set the GMass Action to Just create drafts. This will ensure that no emails are actually sent.
- Click the red GMass button.
- After the Drafts are created, you can click the link in the email you will receive to DELETE the Drafts.
Now your Suppression List has been created and you can choose this campaign to suppress these addresses.
What’s the difference between my Unsubscribe List and a Suppression List?
They are actually quite similar, in that both lists are used to filter out recipients from a campaign.
Your Unsubscribe List, however, is universal to your account, and is used to filter out recipients for all of your campaigns automatically. You can’t control when the Unsubscribe List is used to filter out recipients, because it is always used on every campaign sent from your account. Email addresses are added to your Unsubscribe List when they click the unsubscribe link at the bottom of your emails (if you included it), or if you manually import email addresses into your Unsubscribe List.
Suppression Lists must be applied to specific campaigns where you want to eliminate that set of email addresses for just the current campaign. Any past campaign can be used as a Suppression List, which is why all of your past campaigns show up in the Suppression dropdown menu.
