One of our customers is unable to receive e-mails from campaign monitor (previews or proper campaigns). Unfortunately they have nazi network security policies which blocks all websites and mail servers unless white listed by their IT department.
I send the following mail server domains to the IT department asking for them to be white listed:
m1.createsend.com - m10.createsend.com
m1.campaignmonitor.com - m10.camaignmonitor.com
...but the e-mails are still not getting through (even tho they appear to be coming from m6.createsend.com which is supposedly white listed). Am I doing something stupid here?
it may be useful to know that we're not getting bounces, the e-mails are being delivered as far as CM is concerned.
it is hard to know from the outside, but you may also want to whitelist the IPs listed here: http://help.campaignmonitor.com/topic.aspx?t=77
I have a couple of clients with the same issues. Yesterday I had a case where an IT-departments preferred whitelisting sending domains in stead of IP's. You guys provided me very promptly with that information, so thanks for that.
Two suggestions/questions, that may be useful to other CM-fans too:
(1) Adding the sending domains information to the help topic you mention above.
(2) As with the IP-addresses, you may (?) add new sending domains in the future. It would be great if we could get updates (just a simple email notification or something like that) if and when it happens.
Deliverability being the big issue that it is, this would be a great -- and I guess easy to deliver -- service.
Or (duh).... I could just subscribe to this post and you guys could keep it up-to-date with the latest IP and sending domain info.
