Getting through spam filters
Any of you have any advice on getting through spam filters when emailing your users? I know Return Path helps improve the success rate but not sure how much they charge.
There's no one way to avoid spam filters, even big corporations have issues getting emails into inboxes. There are some ISPs who block emails based on many they receive from an address in a period of time, but that's just something you have to deal with and figure out when it comes to sending out bulk emails.
