1. Don’t send unsolicited emails to people that didn’t subscribe to your site.


2. Send emails using an authenticated SMTP server e.g smtp.example.co.za or mail.example.co.za


3. Write enough text. Spam filters dislike emails with more than 3 or 4 images.


4. Avoid “spammy” words, such as:


– “free”

– “unbelievable”

– “Dear”

– “Viagra”


5. Include a legitimate physical address in your footer.


6. Be clear of where you send from:


– SMTP providers can be authenticated as legitimate senders of emails using your domain name. That’s done with a an SPF record.
