Bring inactive users back into the fold by crediting their accounts.

If a user becomes inactive, they may just need a little nudge. Give them that nudge by crediting their accounts so that they can use the service again — on you.

If you've got dormant users, you may be able to get them back in action by crediting their accounts. Send them an email to let them know that the next month (or two) is on the house, and invite them to come back and take advantage of it. This approach of adding funds to the account can work for paid users with failed billing or cancellations. And it can work for inactive free users too, if you upgrade their accounts temporarily.
