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

To fix the issue with your emails being blocked, you need to update your DKIM and SPF settings in your Ionos email server. Start by checking your DKIM records to ensure they're correctly set up. Then, adjust your SPF record to include the IP address from which you're sending emails (74.208.4.197). You can find detailed setup instructions on the Ionos website or by reaching out to their customer support.


After making these changes, give it some time for the updates to take effect.
