I've been using EezyCollab for my influencer research, and it's been a game changer. The platform's ability to centralize everything makes managing campaigns so much quicker and easier. The accuracy of the search in my niche is around 90%, which is way above average compared to other tools I've used in the past.
I haven't used the inmail feature yet as I do DM outreach however I might give it a go since it's there.
Plus, the responsive support team is always there when I need help.
