Most tools use a one-size-fits-all approach, but Upfluence instead uses an approach that concentrates on flexibility. While it is a bit more complex than other influencer relationship management tools, its interface is still easy to understand and use. All things considered, it is one of the best tools to use, especially if you rely on Instagram a lot. For easy reference, all email correspondence is archived into Upfluence and team members can view any messages sent to and from each influencer.
