We have an application here that delivers monthly newsletters for our clients. The subscribers add the newsletter campaigns through our customers websites.
My question revolves around proper delivery of newsletters to ensure that we are not breaking SPAM rules and not being flagged as spammers.
Currently the newsletters that are sent out have the FROM: field set to the clients email address (ie. JoeShmoe@aol.com) To my understanding this would violate SPF rules as our servers are not allowed to send on behalf of AOL. We also do not have any bounce tracking as the bounce path remains the same as the FROM address, what would we need to change in order to be able to receive the bounce-backs?
How do companies like Constant Contact, Vertical Response, Net Atlantic do it this way and they seem to always ensure the message will get through?
I hope there is someone out there that has experience with this subject that can shed some light on our situation.
