HIE 5 enables you to schedule your emails, sending them at a specific date and time - ideal for marketing mailshots, newsletters or seasonal greetings. You can also send emails in batches (e.g. 50 mails at a time).
See Scheduling eMails for instructions on how to schedule your emails.
Send in batches. If you have a large mailing list, use the Scheduled eMail Manager to send out your emails in smaller batches (e.g. 50 contacts at a time). This may help reduce the likelihood of your targeted emails being incorrectly marked as spam or junk mail.
