If you see this addition to your signature at the bottom of the Compose/Reply windows, it means that you are on the Ambassador plan. The Ambassador plan is a free version of Hiri with a catch. And this is the catch.
In return for getting to use Hiri for free, "I'm getting my email under control" will be appended to the bottom of every email you send. You are basically paying for Hiri by helping us spread the word.
The Ambassador plan is experimental and is not available to everyone. We limit the amount of free licenses we give out. We might pull this plan if it's not really helping with our marketing. Don't worry though - if you are on the Ambassador plan now, you will be for life.
I want to remove this signature - what can I do?
If you want to remove the signature, you will need to pay for Hiri. Just click on the 'x' and you will be brought to the pricing page where you can purchase Hiri. Once you have purchased Hiri, just restart and the signature will disappear.
