Persistent Gmail Spam Classification

I am experiencing a persistent email deliverability issue with my Outlook account, ******@outlook.in.

Emails sent from this address are being classified as spam by Gmail, even when they contain only simple text without links or attachments.

I have examined the original email headers and confirmed the following:

• SPF: PASS

DKIM: PASS

DMARC: PASS

ARC: PASS

Microsoft BCL: 0

Sending IP: 2a01:111:f403:d405::2

Despite successful authentication and delivery, Gmail continues to classify these emails as spam, stating that the messages are similar to previously identified spam.

I request your technical team to:

Investigate whether my account has any sender-reputation or deliverability restrictions.

Check whether the outlook.in domain or associated outgoing infrastructure has any known Gmail deliverability issues.

Review whether any account-level remedial action is required.

Escalate this to the relevant Outlook.com deliverability team if necessary.
