Hello, please look into the following and also DMARC record:

SPF​

The SPF record for your domain should include all email senders for your domain. If your third-party senders aren't included in your SPF record, messages from these senders are more likely to be marked as spam.


DKIM​

Important: Sending to personal Gmail accounts requires a DKIM key of 1024 bits or longer. For security reasons, we recommend using a 2048-bit key if your domain provider supports this.


DMARC​

DMARC tells receiving servers what to do with your messages that don’t pass SPF or DKIM. Set up DMARC by publishing a DMARC record for your domain. To pass DMARC authentication, messages must be authenticated by SPF or DKIM, or both. The authenticating domain must be the same domain that appears in the message From: header.

Please also setup a DMARC record as google is quite strict lately
