Several factors can cause emails to go to the spam folder instead of the recipient's inbox. Here are some common reasons:
Spam Trigger Words:
Using words or phrases that are commonly associated with spam in the subject line or content of the email can trigger spam filters and cause the email to be flagged as spam.
Poor Sender Reputation:
If the sender's email domain or IP address has a history of sending spam or engaging in suspicious activities, email providers may consider their emails as spam and route them to the spam folder.
Lack of Permission:
Sending emails to recipients who have not explicitly granted permission or have not opted in to receive emails from the sender can result in emails being marked as spam.
Low Engagement:
If recipients consistently delete or mark emails from a particular sender as spam without opening or engaging with them, email providers may begin filtering future emails from that sender into the spam folder.
Misconfigured Emails:
Emails that are not properly formatted, contain broken links, or have technical issues can be seen as suspicious or spammy by email providers.
High Complaint Rate:
If recipients frequently mark emails from a particular sender as spam, it can negatively impact the sender's reputation and result in future emails being sent to spam.
Absence of Authentication:
Emails that lack proper authentication, such as SPF (Sender Policy Framework) or DKIM (DomainKeys Identified Mail) records, may be more likely to be flagged as spam.
Blacklisting:
If the sender's email domain or IP address is listed on a spam blacklist maintained by email providers, their emails are more likely to be filtered into the spam folder.
It is important to follow best practices, such as avoiding trigger words, obtaining permission from recipients, maintaining a good sender reputation, and ensuring proper email authentication, to minimize the chances of emails being marked as spam

Use Spam Trigger Words Sparingly and Within Context
So long as you use email marketing best practices and use spam trigger words within context, you can bypass spam filters.
Spam filters have become much more sophisticated in recent years. Using one or two phrases won’t hurt you, but make sure to only email customers who want to hear from you and to always personalize your emails. Doing so will optimize the results of your campaign and keep you out of spam folders.
