I spent most of my day last week trying to set up and test a lead magnet--a calendar template with tips/tools for marketing. When I tested the automation, it took 20 minutes for the email to be delivered.
I did not have a delay timeframe on the automation so it should have been immediate. I had to rework the entire workflow.
This is definitely strange. You may not have had a delay in place, but did you check the workflow runtimes in the workflow settings? If you set the workflow to function only during set times, that could have been the reason it was delayed.
Were you able to test the workflow again and see the actions execute as expected? If not, I strongly recommend opening a ticket with HubSpot Support so that they can help you further troubleshoot the issue.
