Why is it free?
The first reason has to do with the fact that our business is to automate cold email outreach.
If more people get good results with cold email, more people will use our product. This means it's in our interest to make our users successful at cold outreach, and providing a free deliverability-enhancing tool is a great way to do that.
The second reason is simply improving the quality of our Auto-Warmer. The more inboxes are in our Auto-Warmer group, the better the quality of the Auto-Warmer, and the more advantageous it is for its members.
Currently, there are over 4000 real-people inboxes in our Auto-Warmer group, and the number is rapidly growing.
