However, Not only are our open rates insanely low (we average 30-50% open in Mail Chimp and are getting .9% opens with the few campaigns we have sent) but I am not even getting my test emails to my @gmail address from campaign.

Does anyone have advice on who can help us?  Support has been zero help troubleshooting this issue (have submitted several tickets but they say it's fine) , we feel we followed all of the proper set up steps but we literally can not send anything from zoho right now. 

TIA for your replies and help!
