If you are sending out email marketing or emails to several addresses, it is important to understand why an email might get flagged as spam. This will allow you to avoid including some 'triggers' with your emails and make sure your emails get delivered without delay. The following are some points you should bear in mind.
1. Authenticate your email: Implement SPF, DKIM and DMARC authentication to prove the authenticity of your emails.
2. Avoid spam trigger Words: Words like "Free", "Earn Money Fast" and "RE:" (in the subject line) are common triggers for spam filters.
3. Keep the subject line short and descriptive: Avoid using all caps and excessive punctuation.
4. Provide a clear Opt-Out method: Include an unsubscribe link in every email to allow recipients to opt-out of your mailing list.
5. Use a consistent sending address: Sending emails from a consistent address increases the likelihood of future emails being delivered to the inbox.
6. Avoid including attachments: File types such as .pdf, .docx, .xlsm, etc. can trigger spam filters, so avoid including them if possible.
7. If you are sending attachments, .zip the files before sending them.
8. Avoid sending large emails (this includes all the content of the email, images, body text, attachments, etc.)
9. Maintain a Clean Email List: Remove inactive subscribers and bounced email addresses from your list to improve your overall sending reputation.
10. Keep the design simple and text-based: Avoid using too many images or graphics, and stick to a clean and simple text-based design.
11. Personalize your emails: Use the recipient's name and other personal details in the email to increase engagement and avoid looking like spam.
12. Test before sending: Use an email testing tool to check if your email is likely to be flagged as spam before sending it to your subscribers.

14. Avoid sending bulk or mass emails: Instead, segment your email list and send targeted and relevant content to each group.
