Siteline - Notice history

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.

As of 7am PT on Aug 16, Microsoft has confirmed that our IPs have been unbanned. We have not seen reports of delivery failures since Aug 15 at 7:10pm PT. We will contact users that have been affected with a list of failed notifications / submissions.

Deliverability issues are still ongoing. We attempted to contact Microsoft directly to no avail.

Emails to Microsoft/Outlook are now getting delivered properly. We will contact affected customers for re-submission of pay apps, lien waivers, and other documents.

Sendgrid/Twilio has confirmed that there is a widespread issue where emails to Microsoft/Outlook are not getting delivered. You can visit https://status.twilio.com/incidents/f8vsxj0hk5by for more information. We'll monitor the situation and email affected users once the problem is resolved.
