Hi, Koha will generate emails triggered by various actions (overdues, holds, suggestions), but there is currently no way to email all patrons from inside Koha for a message from the library. I think the easiest way might be to export all email addresses using an SQL report and use the data for creating a mailing list. There is also a system preference to display a message in all patron accounts in the OPAC - OPACMySummaryNote. Hope this helps, Katrin Am 03.04.2015 um 07:21 schrieb Habibullah Helal:

Dear All, I would like to know that, is there any option that I can send a notification (message) to all patrons from KOHA by one mail (by 1 Click)? Please inform me..
