They send so much "follow-up" e-mails from chats that it's basically indistinguishable from real spam?

#4Every email service provider has to deal with this from time to time, but well-designed email operations and infrastructure should generally limit the impact to a small subset of customers - usually, especially with a known high-volume sender, Spamhaus will list as narrow of a range as possible to prevent false positives.
The fact that this applies so broadly implies that Intercom may need to rethink some of the details of their email operations, and/or beef up their anti-spam enforcement efforts.
As an aside, it appears Intercom uses Mailgun with dedicated IPs, judging from recent samples.

My personal mail server kept getting IP blacklisted, but only on Microsoft Outlook. I kept submitting it as non spam, they kept accepting and then couple days later it was back on. No mail relay, no unwanted traffic, nothing.
They seem to have some weird way of blacklisting whole IP ranges. In the end what helped was moving the machines at hetzner to more expensive ones, which put them in different IP ranges.
Even before the age of Mailgun I remember outlook being a problem at a startup I worked at. There's also dnswl, but dnswl doesn't help for low volume senders.

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.

#7I’ve received spam from Intercom many times. They have always responded swiftly when forwarding the messages to abuse@. No spam at all would be better.

#8Rightly so. Intercom are, in my experience, a facilitator of spam, dressing themselves up as some sort of communication revolution. I've had their IPs blacklisted on my own mx for two years or more.
