Is there some Indy best practice to avoid to generate email marked as spam?

Question

This question is the non spam bible.

Anyway in addition to that when generating programmatically emails with Indy which are the best practices to follow to minimize the possiiblity of being marked as SPAM?

Answer 1

In general, I would say:

• Fewer recipients (more emails, if necessary)
• Avoid symbols in the subject
• Avoid excessive symbols and spelling mistakes in the body
• Keep all HTML properly formatted with end tags and proper headings
• Avoid profanity and questionable phrases
• Make sure all required email headers are filled in correctly (including "Content-Type", "Precedence", "From", and "Reply-To")

That's just the general stuff off the top of my head.
