Zoho not processing web site contact form emails

Zoho not processing web site contact form emails

I recently switched to zoho and ever since I stopped getting my contact form submissions from website to my zoho email. The form processor is using php. 

I removed the SPF records in my DNS as well to see if that solves the issue, it did not.

I really need some help here.. The form submissions are successfully being delivered to my gmail account, but not the zoho email.
