Emails to Microsoft 365 / Outlook are not going through
  • Update

    Update

    Some of our customers are still reporting failed email deliveries. Although our email provider shows no failed delivery on our end, it is possible that our emails are ending up in Spam, due to harm in IP reputation during this incident. To ensure delivery of our emails, please check your spam folder and mark any Siteline email as non-junk. You might need to ask your IT team to whitelist our domains and IPs to ensure delivery moving forward:

    Sending domain: em3219.siteline.com
    IPs: 168.245.95.55, 159.183.87.133
    Senders: *@siteline.com, support@siteline.com, account@siteline.com, documents@siteline.com, notification@siteline.com, submissions@siteline.com


    We'll keep monitoring the situation and post here with more updates.
