When notifications do not arrive

If a document was read but no notification came, the cause is almost always one of the following. Work through them in order.

The notification settings screen, where notification timings are selected as chips

1. Have you signed up?

View notifications are available after signing up for a free account. While using the trial without an account, you can still see reading states in the document list, but no notifications are sent.

Documents and share links from the trial carry over to your account.

2. Is a notification timing selected?

Notifications are only sent for the moments you select. Check Default notification timing on the notification settings screen.

TimingSent when
OpenedThe link is opened
Half readThe reader reaches the halfway point
Fully readThe reader reaches the last page
RevisitThe same person opens it again
High interest signalPages are read deeply and for a long time

Opened and High interest signal are enabled by default.

If no timing is selected, nothing will ever notify you. Check whether the settings screen is showing a warning.

Notifications can also be set per link. If a link has notifications turned off, it stays silent even when default timings are selected.

Open the document and check the settings of the link you sent. When a link specifies nothing of its own, the default from the settings screen applies.

4. Is the email arriving?

Notifications go to the email address registered with Terasu.

  1. Check your spam folder
  2. Allow the @koromo.io domain
  3. If you use a company address, ask your administrator whether a filter is quarantining the messages

5. If you use Slack

Slack notifications only reach connected workspaces. Without a connection, notifications are email only.

See Slack integration to connect one.

Still nothing

The view itself may not have been recorded. If the link still shows "Not viewed" in your document list, either the recipient has not opened it, or the link has expired or been stopped.

See Share link settings for expiry and stopping.
