Regular promotional email

[محروم.كوم]

I have a community with circa 8K members, just over 1.1K active.
I thinking of doing a monthly email to members.

With some product reviews, forums news, pictures, etc...

I'm very well aware of this being considered as spam. And anything I do would have full opt out facilities and would come from a monitored mail box.

I'm interested in what experiences others have had.

Plus any recommendations on software solutions / services / mods to do this?

Thanks. __DEFINE_LIKE_SHARE__
