I love this sketchnote by Selina Wragg .
This is one of my favourite sketchnotes! I created it after watching a joint webinar between Kissmetrics and Campaign Monitor, about how to create a high-converting email campaign. It lists some crucial points that every marketer should include on their checklist when creating campaigns, and it's really helped me in my job. I went into more detail in this accompanying blog post: http://selinawragg.com/sketchnote-blog/how-to-design-a-high-converting-email-campaign.
Well done Selina!
