Before we support you with your switch to us, we'd like to point out a few important points:
Use your move to Quentn to do a proper tidy up and get more visibility back into your business and campaigns.
Which campaigns do you need in the future? You shouldn't transfer old or inactive campaigns. Maybe you have a campaign to promote a webinar, but don't currently have a webinar? You can always import our campaign templates.
Can't see the contact for the tags? Delete all tags that have become irrelevant (such as smart tags). Who cares if someone once visited your website or clicked a link? Every tag you don't need helps you to keep an overview and makes Quentn easier to use. Always remember that you can build campaigns in Quentn without tags at all, and they only serve as information for later selection anyway.
