Their terrible marketing ethics. MobileMonkey sent me numerous emails (after I had unsubscribed several times), bot messages on Facebook, and auto-mated e-mail marketing newsletters. It's as if they either don't give AF or their 'unsubscribe' link is fake and does absolutely nothing. They have called me 6 in the morning twice already (all within 4 days!!). Every time they email me I reply with please unsubscribe. Not only they haven't replied to my concerns, but the same person, David Mercurio, their "Senior Account Executive" has continued to spam me, trying to upsell me with his template messages. This is just absurd! I wouldn't recommend them to anyone. I have received less spam from signing up on unknown shady websites than I have from MobileMonkey. Shame on them for creating such an image for our industry!
