What the experts say7Expert opinions
Expert from Email Geeks suggests reminding users at signup to check their spam folder and move the email to the inbox to send a strong signal.
Expert from Email Geeks explains that 1-2 spam traps a month on a transactional stream with COI isn't a huge deliverability problem and is considered normal or even low.
Expert from Email Geeks shares that delivery problems sometimes occur on COI IPs because they handle "bad" mail collection and lack consistent "good" traffic to balance it.
Expert from Spamresource.com explains that there are different kinds of spam traps (pristine and recycled). Pristine spam traps never signed up for emails, so hitting these indicates a serious list acquisition problem. Recycled spam traps are old addresses that have been converted into traps, which suggests poor list hygiene. Hitting any spam trap, even a small number, is bad and requires immediate investigation.
Expert from Email Geeks explains that fixes differ for blocking versus spamfoldering, making clarification the initial step.
Expert from Wordtothewise.com shares that Microsoft's Smart Network Data Services (SNDS) is a valuable tool for identifying and addressing deliverability issues with Hotmail, Outlook, and other Microsoft properties. SNDS can provide data on your IP reputation, spam complaint rates, and other factors that affect deliverability. Regularly monitor SNDS to identify and resolve any problems before they impact your sending reputation.
