You may have spent some time building an email campaign and you've sent it out to your recipients. You need to re-use that campaign to save you time and then to re-edit it to be relevant for your next campaign?
All your sent campaigns can be re-cycled in the following way:
1. Create a new email campaign on Step 1 and include a campaign name and subject line. Proceed to Step 2...
2. On Step 2 click on the "past emails sent" tab and you will see your sent campaigns to re-use. Click on the campaign name to re-cycle it, then you can edit further on Step 3.
If you have any further questions about this please raise a support ticket.
