Web to Lead not Triggering Workflow Automations

Web to Lead not Triggering Workflow Automations

I have a few forms on my website that I set up as web to lead forms manually (I did not use the website integration tools).  All are working fine.

This morning, I set up a workflow rule that if a lead comes in with certain criteria in a field, it automatically sends an email and updates the lead status.  It is not doing either if the lead comes from my website, but if I manually enter the lead with the exact same information, it is working fine.

It is set to execute on create.

Is there a reason that it isn't working correctly when coming from the web?

Thanks
