• Email batch size: When sending invitations or reminders to survey participants, this setting helps the administrator determine how many emails can be sent in one bunch. Different web servers have different email capacities, and if your script takes too long to send many emails, the script could time out and cause errors. Most web servers can send 100 emails in one go within the default 30 second time limit for a PHP script. If you get script timeout errors when sending large numbers of emails, reduce the email batch size using this setting. Clicking the 'send email invitation' button that is located on the survey participant toolbar sends one batch of invitations, displaying a list of the addresses to which the email was already delivered and a warning that "There are more emails pending than could be sent in one batch. Continue sending emails by clicking below. There are ### emails still to be sent." and provides a "Continue" button to proceed with the next batch. So, the user determines when to send the next batch after each batch gets emailed. It is not necessary to wait with this screen active. The admin could log off and come back at a later time to send the next batch of invitations.
