I have searched IP blocklist lists, and Constant Contact is still showing as blocklisted for this IP range. 208.75.123.0 - 208.75.123.255 here: matrix.spfbl.net here: IP Blacklist Check - Email Blocklist Checker (dnschecker.org) Our IT department has tried to resolve this issue through Constant Contact, as have we through several phone calls. We either cannot get through by phone as it is a lengthy VR and a wait to talk to someone or cannot resolve the issue in general. It is also not easy to find the phone numbers for the department you need to speak to, so if you do call, you may experience a wait and an additional wait after your transfer. Our deliverability went way down, and over 60% of our contacts no longer receive our emails, more than 600 subscribers. It happened all at once, so we are not sure why that many connections went down other than a spam list. Can anyone assist, or has anyone had the same problem that got it resolved?
