Influencerbit allows you to capture social media of your customers. Then you can use Klaviyo / Send-in-Blue / MailChimp (any other ESP) to fully automate your interactions with these influencers. Influencerbit then provides you the analytics on their posts / stories when they mention you - Reach, likes, User Generated Content, impressions, etc.
To do anything commission / tracking based, you need refersion.
We embed an Instagram field in your Refersion form for the affiliates. This instagram username is passed to Influencerbit and we track these affiliates on Instagram in Influencerbit dashboard.
