How can I find the ISP address of our outgoing campaigns from Marketo?

I am trying to find a way to get our campaigns through to companies that are collectively blocking our eDMs. I need to know the ISP address Marketo is using (because I know it's not my company's address). Any insights would be much appreciated!!

A lot of companies have corporate level spam screening, which will probably be blocking the email based on the keywords in the content, and the address of the sender.  If you really want to know the IP address, it will be in the header of the email - perhaps you can use this tool: http://whatismyipaddress.com/trace-email

@Andrew P Marketo may use several IPs to send your email over time.  Every email comes from one IP but that isn't guaranteed to be used later (unless you specifically pay for a dedicated IP).  

@Lorraine S Marketo sends from IPs in these ranges:

199.15.212.0 - 199.15.212.255
199.15.213.0 - 199.15.213.255
199.15.214.0 - 199.15.214.255
199.15.215.0 - 199.15.215.255
192.28.146.0 - 192.28.146.255
192.28.147.0 - 192.28.147.255
94.236.119.0 - 94.236.119.63
37.188.97.188
185.28.196.0 - 185.28.196.255
103.237.104.0 - 103.237.104.255
103.237.105.0 - 103.237.105.255

you can pull a list of people who were sent an email and check the bounced reason, or you can send yourself an email, then look at the original source for the IP of the sender.

Re: How can I find the ISP address of our outgoing campaigns from Marketo?

Yes but @Josh the IP address you are sending from at the time of your test is not necessarily the one originally used to send to the recipient. Unless you have a sample from that original send, you don't have a reliable source -- and it is frequently the case that .123 can be blacklisted while .124 is not. If you want to be reliably whitelisted by a recipient you need to give them all the ranges. That list of IPs is provided by Marketo specifically for whitelisting and/or forensics.
