Campaign summary in OneNote
I often work in OneNote to summarise either my plans for the near future or to have the overview of the work done. I used to organise a startup conference and we had to market it, obviously. Email was one of the ways to let people know about the event and we needed to keep track how successful the email sending campaigns were. With this recipe, it's quite comfortable to integrate the summary of the campaign into OneNote if your whole life is basically in there, just like mine.
