How can I create a random email reminder in Gmail or Inbox by Gmail?

Question

I would like to create a random email reminder in Gmail or Inbox by Gmail to for instance:

• create a reminder for myself to tag a Flickr image
• read one of my Pocket articles
• to perform other regular tasks that I want to do sometimes

Answer 1

Inbox by Gmail allows you to create a "reminder" (pin) and snooze it to "someday".
