Not to be trusted

1) After updating to ver 5.2.1 the plugin disappeared from the WordPress menu. Basically Mailjet made its plugin unusable and abandoned it. 3 weeks since I opened the support topic “Error Update 5.2.1” and still no answer from Mailjet.

2) I believe Mailjet had a security breach. I have two new emails registered in Mailjet and both are spammed only by addresses impersonating Mailjet’s domain. Mailjet lost it’s customer data (at least their emails).
