I've tried to send it to three testers- all complain that they're not receiving the mail. I tried sending it to my own gmail and hit the same problem.
I'm a little worried that when we send the campaign we might face the same problem.
Maybe I should run a spam test.
Advice would be appreciated.
Just to add to this I ran a spam test and it showed that it is being delivered okay to Gmail. However I then checked my Gmail Spam folder & found the newsletters there.
Yes, typically it will be your content being flagged by Gmail as junk - it can be a pain to work out why, as you may need to do some trial and error testing to see what is triggering it.
