Reading what was sent

Yes. Under Mail settings, fill in the user name and password of a mailbox on your own domain at Own mailbox, and click Send a test mail. Without it, mails go out through the Qsite account and replies still reach your sender address.

Yes. Go to Mailing and choose New mailing. Send to one or more member folders, or to all members with an e-mail address. Every mailing has an unsubscribe link, and members who unsubscribe get no further mailings. Under Sent items you see per recipient whether the e-mail went out.

First check the addresses under Send to in the form, and your spam folder. All messages are also stored in the admin: open the form and look under Submitted. If messages are there but not in your mailbox, check Mail settings or contact support.
