Thank you @prashantrai.
I will look into configuring an SMTP plugin. However, I’m still curious why notifications would be received initially and not now.
Additionally, I have filled out the contact form (as a test) and submitted from my personal computer 4 weeks ago and it was received at the “send to” email address. Now when i do the same test (from the same computer) it is NOT received by the same “send to” address. Neither in the inbox nor spam folder.
As a further test, I sent an email from my personal email box to the “send to” email and it was received.
In short, the “send to” email address received both the contact form and personal emails from my computer 3 weeks ago; but now only receives personal emails and not contact forms–and no changes were made to the contact form or settings…
Any ideas?
