In this post, I will walk you through setting up a system where anyone who emails you can be automatically added to a GMass campaign with the option of sending a sequence of follow up emails automatically. (As a bonus, I include a little bit of spreadsheet formula magic to make it easier to later personalize your GMass-sent emails!)
For example, you may have a "mailto" link on your web page stating, "send us an email if you'd like more information." Or a potential customer may just email you directly. In either case, when an email is then received, the sender is automatically subscribed to an email automation sequence.
