I am having problems with Gmail blocking emails altogether.

I am having problems with Gmail blocking emails altogether. They aren't even going to spam. GMAIL just won't receive them at all? Will creating a filter help with this? My emails are forwarded from a separate server and they are received there but some are just not received by gmail. How can i fix this?

I tested a form with my Gmail account, but I wasn't able to replicate any problem, the submission arrived.

Could you please let us know which form you tested and did you try with some other Gmail email?

Thank you!
