They don't run their own autonomous system, a bad indication.</p>
<p>Senderbase shows fourteen bl.spamcop.net listings in their 46.232.183.0/24 CIDR out of seventy-seven active IPs at the time of writing. Earning full blocks by Spamcop is no minor feat, requiring direct manual filings from many people.</p>
<p>Most of the MailChannels ranges are blocked here due to residing in bad ASNs, and of the two messages bounced by the MTA 17 and 24 months ago (no ham from them ever) one was to a pristine spamtrap address and the other was from cute-girl name at bogus domain.</p>
<p>This ESP seems to have one clean netblock in a clean ASN, presumably for the better quality customers.</p>
