Rollup frequency is completely dependent on whether or not one of the email addresses that you rolled up actually sends out an email that day. If at least one of those addresses sends you an email that day, you should receive your rollup with that email and any others that were also sent that day from your rolled up addresses.
On the other hand, if you start receiving your rollup emails in your Inbox instead of inside the Rollup, it could be caused by one of the following:
1. Your rollups have been deactivated from the Unroll.Me web app settings. To fix this - open the Unroll.Me page on the web, and if you see the section “Activate My Rollup” with a green button, it means that you deactivated your rollup emails. Please click on the “Reactivate My Rollup” button to activate rollup emails again.
2. Your Unroll.Me account has been disconnected (you received an email “Unroll.Me has stopped working”). To fix this - follow the link Unroll.Me. You will be redirected to the re-authentication page, where you will be prompted to connect to Unroll.Me again.
