In digital marketing for businesses, email marketing is widely used and serves as a primary channel for B2B digital marketing. However, many companies find that their carefully crafted bulk emails are often flagged as spam by recipients’ email systems. This not only damages brand image but also significantly reduces marketing effectiveness.

Bulk emails ending up in spam folders are mainly influenced by factors such as email content, sending methods, and technical settings. The key reasons can be summarized as follows:

1. Lack of Targeted Marketing Management
   When sending bulk emails, using the same content for all recipients may irritate those who find the message irrelevant. If users report the email, it can affect the deliverability of the entire batch.

2. Low Sender Reputation
   If the sender’s domain or IP address associated with the email marketing platform has a history of sending spam or has been reported multiple times, email servers may automatically lower its reputation, causing emails to be directly classified as spam.

3. “Spam-like” Content Characteristics
   Many users of bulk email tools tend to use excessive promotional language, exaggerated phrases, and too many external links or images—all of which are red flags for spam detection systems. Frequent use of words like “free,” “limited-time offer,” or “click to claim” can trigger the system to mark the email as promotional.

4. Poor Quality Recipient List
   Many users of email marketing platforms import large numbers of unverified email addresses or even purchase third-party email lists. These lists often contain invalid, inactive, or spam-trap addresses, leading to high bounce rates or reports, which harm overall deliverability.

5. Excessive Sending Frequency or Volume
   Sending a large number of emails at once or frequently dispatching bulk emails may be flagged as “suspicious activity” by email servers, triggering spam filters automatically.
