No worries,
Their servers aren’t amazing, but they’re incredibly cheap so I thought they might be good for affs, you do need a registered office to sign up though, even though they’re quite lenient with bounce rates etc. Basically old lists that you haven’t cleaned in a while are fine. So around the 30% mark no worries. (so in theory you could get away with quite a spammy list – not that I’m endorsing that behaviour just giving a point of reference).
