Forwarders are included with Rise and Roar. Spark doesn't include them.
A forwarder passes email sent to one address on to another, without storing it in a mailbox. For example, you could forward sales@yourdomain.com to your own email account.
sales.Forwarding to Gmail, Outlook.com or Yahoo? These services sometimes treat forwarded email as spam or reject it, especially forwarded spam. For important mail, create a mailbox and add it to your email app instead. See Creating an email account.
Spark includes 10 autoresponders and Rise 20. Roar has no limit.
An autoresponder sends an automatic reply to everyone who emails an address, for example to confirm you've received an enquiry.
