I deleted a campaign. How to get it back
Hi @Phong_Web if you contact the support team (chat is currently available at this hour) they can assist with restoring the campaign. I must warn that Infusionsoft is unable to restore any contact back to their place in sequences, that may have been in the campaign before it was deleted, but the campaign itself can be restored.
Once support has restored the campaign, it will need to be republished, to start working correctly.
