We're so excited to have you join Knock!

Every company is different, but some email servers are setup to block emails from new senders, so Knock's helpful notification emails might end up in spam folders, queued up on a server, or undelivered altogether- not good!

To ensure that all of Knock's emails get delivered properly, please have your IT department allowlist the following domains:

  • knck.io

  • bulk.knck.io

If you have any questions just chat us in the bottom right corner of this page and we'll be happy to help!
