I’d also like to be able to use Bank Holidays as triggers.
Our customers never remeber to change their call routing for Bank Holidays. It would be great to have a trigger send, for example, 7 days BEFORE [Bank Holiday] send email [Bank Holiday reminder].
Being able to manually set, with Hubspot, a list of dates that are exceptions to normal days might be the way. Then you can also have an option in Workflows to send, not send, or pause for manual triggering, on those days.
