Emails being stopped by IT department

[rooter]

Hi all,

I am having increased problems with several of my larger clients whose IT departments are filtering out emails after they arrive on their servers.  In other words, the emails are not being BLOCKED (they do not showup on my blocked reports), but NONE of the emails going to some clients are being opened.

I am not able to gain access to an actual IT person within these companies.

Am I dead in the water?

Hi @rooter 

We certainly understand how important deliverability is. One troubleshooting step was always suggest is sending your contact a blank test with an altered subject line. This allows you to see if emails are not being delivered due to content. Were any of your contacts able to receive this email?

Whitelisting Constant Contact in their security system is another great step for troubleshooting. However you mentioned being unable to gain access to an IT person within these companies. Because of this I would suggest reaching out to one of your contacts directly with the steps for whitelisting. This contact can then internally reach out to their IT department with the steps you have provided. Feel free to also reach out to our Deliverability Specialists. These support agents can help look further into these contacts or any other emails that not be received.
