Hi there
New to the forum and looking for some help
Is it possible to send an email to everyone in my Address Book?
Thank you in advance
The simplest way would be to create a group and add all of your contacts to that group and then to send to that group. Keep in mind that while Roundcube will allow to send to your whole address book, your mail server may (and most likely does) have some sort of sending limits set that will mean your email may get blocked or not be send to all recipients.
