Unable to receive email

I have a domain www.codezlabs.com. The website is hosted on AWS, I have successfully saved and updated MX records and SPF entries  and also checked records in mxtoolbox inspite of this I am unable to receive any email from sender. 

Here is my MX records set on AWS:

10 mx.zoho.com.
20 mx2.zoho.com.
50 mx3.zoho.com.

SPF Entries

"v=spf1 include:zoho.com ~all"

I am also attaching the screenshot of MX records and SPF entries.
