Emails may get filtered out due to multiple reasons:
- Spammy Content: Words and phrases commonly associated with spam, such as "Buy now" or "Free," can trigger spam filters. - Poor Sender Reputation: Email servers track the behavior of senders. A poor reputation can cause your emails to be marked as spam. - High Bounce Rates: A high number of undelivered emails can negatively impact your sender score. - Lack of Authentication: Emails that are not authenticated using DKIM, SPF, or DMARC protocols are more likely to be flagged.
