Brevo Sendinblue by Combidesk

This app imports bot (fake) accounts from Shopify and messed up our Black Friday campaign causing thousands in lost sales. They will not take responsibility for it either. No support on Black Friday to fix it, really?
We managed our SendingBlue account manually and it's as simple as importing accounts who actually placed an order as opposed to taking everything in. If you can't tell a robot-created account from a real one, then find another job.
Stay away from this company.
