Marketing Campaign Email blocked for my shop?

[VDG]

When I try to send a marketing campaign email I get the following:

"Your email couldn’t be sent

Shopify Email is blocked for your shop. Contact Support to troubleshoot the issue."

Since I can't actually contact anyone at Shopify right now, what am I supposed to do?  This feature worked last week, and doesn't work all of a sudden?

Ambiguous messages like this are extremely annoying, as they could have just sent an email saying the reason or something along those lines.

Hi,
Don't worry it seems like any misjudgment or policy violation case or any change in the policy of Shopify. Which may get resolved
You can directly contact Shopify support through twitter: https://twitter.com/ShopifySupport or I would suggest you can directly ask any of the Shopify staff members from the community, like @Dani @Hyde, they both can help you better in this matter.
Thanks

Don't have a twitter account and not going to start one for this purpose.

Amazing how I can't get in contact with support that I literally pay a monthly fee for.

Hello,
you can ping @Dani and @Hyde in person.
Thanks

Hi did you get any help on this? It's just happened to me too!

[VDG]

Nothing.

This is becoming very annoying.

Yes it is annoying, I sent my first Email last week with no problem and
just now when I go to make the next one is says 'Shopify Email is blocked
from your store'. I have contacted support will revert back if I get any
reply.

This just happened to me. This is getting annoying. First Google Ad Words blocks me the first day I opened an account and now this. How am I suppose to advertise?
