Adding variety to reminder emails

Between once and 3 times a week (depending on user's settings), something new to do on our product comes up (always on the same days at 9 am, on monday, wednesday and friday).

Until now, we have sent simple email reminders each time. We feel that we could make those reminder emails more user-friendly, basically make the user come back on our product without sounding too much like a reminder, for example:

  • Introduce features that the user could be interested in
  • Give some tips
  • even some random facts, why not.
  • etc...

The goal is to make the user come use our product.

Because those reminders alone already send between 1 and 3 emails a week, we force ourselves not to send any other emails (except the necessary ones). This would be a good way not to increase email count and still provide a better experience.

Note that we haven't received any complaint about the number of emails sent, and the power users (really motivated ones) almost all advocated for more reminders.

Advantages:

  • User should open the email more often
  • Provides useful information according to where the user is in his journey
  • Softer reminder (better UX)
  • Doesn't increase the amount of email sent

Disadvantages:

  • Mix content?
  • User could disable this channel and lose this extra useful information

Questions:

  1. Is it a good idea to mix a reminder with other information?
  2. If we do, should it still be written as a reminder with the data being extra, or just forget the reminder part, thinking about the product will be enough as a reminder so no need to mention it?
