As many of you here know [0], mailgun recently got rid of their permanent free trial of 10k emails/mo and replaced it with a 3 month trial with 5k emails included per month. Well, I guess someone realized that transaction fees have a fixed component (or, less sarcastically, they were probably just trying to get people who had no intention of ever paying off), and they now offer 1250 emails/mo for free.
There was a pretty big thread [0] about this a few months ago when they got rid of the free plan so I thought people might be interested.
