2022-09-26: We recently made a change to our mail sending configurations to allow for better performance long-term. Some users have reported that confirmation emails are not going through. We have identified that Office 365 is marking emails from our new IP addresses as spam. We are working on getting this resolved on Microsoft's end. Adding our email domains to trusted lists is the best practice to make sure that we're always trusted, even when we add more email servers.

springshare.com (for getting emails from us)
libapps.com
libguides.com
libanswers.com
libcal.com
libconnect.com
libstaffer.com
libinsight.com
libwizard.com

In the meantime, we recommend asking your IT/mail team to allow emails from the following IP addresses through, as these are used by us to send emails:

69.72.32.253
69.72.34.120
69.72.41.2
69.72.41.28
69.72.45.120
69.72.47.188
159.135.226.248
159.135.233.165
