Some of our clients faced an increased bounce rate over the weekend. It was not related to infrastructure issues, it appeared to be a false-positive block from Spamhaus on some of our IP addresses. We immediately contacted Spamhaus, and the issue was resolved; they confirmed it was a mistake and not related to Mailtrap. We are sorry for your inconvenience, we treat deliverability very seriously.
