How do you make sure email you send programmatically is not automatically marked as spam?

Hi people,

I want so send every week an update by email. But Im afraid that if there are too many emails sent, they will be marked as spam. Any of you has experience sending many emails (thousands) weekly? What techniques do you use?

Thank you
