When you create a campaign in Boma, it automatically saves to your drafts folder until you are ready to send.
If you need to go back and edit a draft campaign, click on your Campaigns link in the top menu. Here you'll see a list of all your campaigns.
You can filter on the left hand menu by Drafts to see all campaigns that are in Draft status.
To edit, click on the name of the campaign to open it.
The campaign will open at the beginning of the campaign setup area. Follow the steps through the setup to complete and send your campaign.
If you need to leave your campaign in the middle of setup, make sure you click the Save & Continue button, and then exit your campaign. The campaign will be sitting in drafts waiting for you to come back.
