Unfortunately, this is a Gmail issue that is not under our control. Google uses their own formula to indicate where they are going to decide to truncate the content of an email. It is a combination of line count and size measurement.
One potential solution is to switch to the newer, Compact Digest. Just visit your Digest Settings and click “Switch Now” under the old Digest notice.
Or, send an email to support@sanebox.com with this request and we’ll take care of that for you.
You may also change your SaneBox Digest settings to have the emailed digest come more than once each day.
So you control the number of digests, as well as the time of day when you would like to receive them. To make desired changes, visit the Notifications section under Settings on your SaneBox Dashboard on our site.
