As an Intercom customer, I just wish we had been proactively notified about the issue. I completely understand that deliverability problems will occur, especially when IP addresses are shared across all customers. I just want to know about the issues when they come up, which didn't happen in this case.

Granted, this could be a great opportunity for Intercom to roll out dedicated IPs and other options for customer to purchase add-ons to not be ensnared in these issues when they emerge.
