I can't read messages from influencers without a prompt requesting me to upgrade. So, I can't read my messages at all. The e-mail notifications don't even show what the messages say so that doesn't work. Not a fan.

Mother Erth

In some ways a great app. But recently discovered a huge flaw that is deceptive. It sends messages automatically to influencers on our behalf and has the "sent from" address as our email address. Responses from influencers get locked behind the paid inbox and not displayed. This has caused us to miss influencer messages.

This may seem small, but is devastating to a small brand that needs to make sure it is responsive and provides an incredible customer experience. It's also misleading to the person to get an email that appears that it is "from" our company email address but their response gets sent to a dashboard somewhere.

This app is a great way to launch an influencer program for a new business. Their user interface is super user friendly and their invite landing page is very straightforward. I got 10 influencers out of my first 25 customers contacted! They also offer new influencers $5 for their first 10 clicks. It's great to include that as a bonus in boarding incentive. Their customer service has been very quick to respond and helpful with all of my new user questions. Love Growsumo!
