Few Question - Zoho Campaigns

Few Question - Zoho Campaigns

In a trial send - Some issues
1) I seem to get the.com emails, but not the .net - checked spam/junk - not there - report shows sent no bounce. i do get the mails when sent as a Test
2) Once a campaign is reviewed and sent, if one needs to edit or make slight changes, is the only way to do so by cloning?
3) Can the embedded videos be played in the same video/email?
