Office 365 blocking campaign emails


Office 365 blocking campaign emails

Hi there, a client has recently complained about our email campaigns getting trapped when receiving through Office 365. It appears that it is being flagged as a potential spam item. Is this a greater issue with office 365 users? How do you suggest I reasonably respond to the following comment?.... "In your line of business, you need be sure that the services you use on behalf of clients manege their reputation properly – evidently that is not the case with – see trapped (Office 365)" .


Re: Office 365 blocking campaign emails

Hi @MichelleT0 


I apologize this is happening with your email campaign! Is your contact receiving any warning messages? Is this happening with any other contact using Office 365? Does this happen with every campaign you send to this contact? The ccsend that appears in you email's header is the email authentication Constant Contact provides to help Internet Service Providers (ISPs) identify your email as being legitimate. I would suggest having your contact whitelist Constant Contact in their security settings. If you have any further questions, please feel free to also reach out to our Deliverability Specialists. These support agents can help look further into this contact and the deliverability of your campaign.
