Dear @IBN,  

Thank You for reaching out Q&A Forum! 

According to your screenshot, your emails were rejected by Gmail because they were suspected to be spam. The rejection came from Gmail's spam filters - exist to stop unwanted, unsolicited, or dangerous messages from reaching inboxes, which automatically block messages that appear suspicious or potentially harmful. 

Based on our research, you may try below options:  

Please check the email validation:  

SPF - Sender Policy Framework 

DKIM - DomainKeys Identified Mail  

DMARC - Domain-based Message Authentication, Reporting & Conformance

You can also check the email validation records online via MX Toolbox.
