Problems with newsletters and Gmail

Hi Guys,

I am now starting to create an affiliate strategy for new client and have a kind of side problem with Gmail. Probably you all know that Gmail started to sort all emails to categories like Primary, Social networks and Promo. My client has a around 90K subscribers for his newsletter, who requested to get it, so no SPAM, but his newsletter now appears in Promo section at Gmail, which is definitely not good at all.

Nevertheless some newsletters I am personally subscribed to are able to break this sorting and appear among my Primary emails (it is not because I set them to be shown in Primary section), so there is probably some way how to fool this crazy Gmail sorting. So please, does anyone have any idea or experience, how to do it?

Thanx a lot guys ;-)

Try changing the wording and subject around, change email addresses too if you can.

Other than asking subscribers to drag and drop emails to primary and having them reply to an email.. I haven't heard of anther way.. would be interested to learn something new. Marketers who use private servers are doing a lot better it seems.
