I have created a workflow for my signups to get a ‘coming soon’ email automation and it’s not sending the emails at all. I have signed up with different emails to see it ‘work’ but nothing is working! Could someone help please?
Thank you for your response. Yes I have checked all these things. It’s really weird as a few weeks ago I had one set up and it was all working perfectly and I deleted it to set up a new one and now it’s not working! 
Just to add, it’s all been set up the exact same way with the same triggers and the same actions etc.
same here. Support is workin on it, but it costs sales

You cannot be using a 3p form, and the customer needs to be subscribed to email marketing.
It worked for several month correctly. Since Monday it does not work anymore.
I reported this yesterday to the team that owns that marketing event. Turns out there was an issue with a recent release that was causing issues with double opt-in. The issue should be fixed now, if you all want to give it another try.
