Problems in connecting zoho to shopify

Problems in connecting zoho to shopify

I had 2 emails and I wanted to add an email and it could seem to work.
So I disbaled Zoho then tried enabling it again. Now I cant receive any email and still couldnt add a third email. Verification codes are not reachinh.

My domain is silabela.com.

Can I please get some help on what I have done wrong? 
1. Not receiving emails anymore
2. Can receive verification code for my third email.


Thanks
