You certainly can! And there are few varieties: The simplest is to just send / forward an email to multiple FollowUpThen addresses For example, sending an email to: firstname.lastname@example.org, email@example.com, firstname.lastname@example.org will schedule 3 separate followups.
You can also use this to schedule private followups for yourself before automatically following up with another. For example you are sending an email to email@example.com cc: firstname.lastname@example.org bcc: email@example.com. This will remind only you after 2 business days. Your recipient will receive another reminder after 3 days.
