I have a bunch of emails from my newsletter that aren't making it into my CC list. Some of them are ".ru," which makes me wonder if it's not a spam filter. But I haven't been able to find anything while searching.
Some emails ARE making it into the list. Which is weird (but would be explained by a spam filter).
Thank you for reaching out to us! I would be happy to assist with this question. For the new sign-ups that aren't making it to your list, are you checking the unsubscribed folder to see if they landed in there? If they aren't in there we might need to take a closer look at this. Please email your username and a few examples of email addresses that didn't make it into the list. Social_Support(at)ConstantContact(dot)com. Thank you for your time!
