Can't send Sequences during contact's working hours??

Hey all,

We are sending sequences through a workflow.

When I discovered that many seq steps being sent during night hours of the recepients, Hubspot support told me the send time is determined by IP TIMEZONE.

The problem is - many contacts in our CRM don’t have IP TIMEZONE as they didn’t fill any form. Rather they were loaded from field events , etc

This is severely hurting our outreach, do you have any ideas? How did you overcome this? Did anyone hear of API solution for that?

The most practical workaround is to manually populate the contact’s “Time zone” property in bulk using an import or workflow, based on the country/region field you likely captured at those field events. Once that property is set, HubSpot’s sequence send-time logic will use it over the IP timezone fallback.
