There isn't much to say here. It was advertised as 'Unlimited content generation for individual prospects via the Chrome extension', but after the AppSumo campaign ended, the limits were reduced to 150 credits in total, for both bulk and individual messages!
With 2 credits per message, that makes a meager 75 messages if you only write individual messages. Quite a difference from 'Unlimited'. Moreover, and this is worth noting, the current Free Plan from Autobound already offers 250 credits - 100 more than what was sold in Plan 1 here.
This approach by Autobound is deceptive and lacks ethics to an extreme degree. This is a rip-off! I contacted Autobound and, unsurprisingly, received no response as yet.
I have also reported this issue to AppSumo support, and I'm confident that they have established policies in place to punish this kind of behavior.
