Adding fellowships to email signature?

[cursoryevent]

So... I won a couple of fellowships this year and the titles tell a good story about my research interests. I won a third fellowship that I am proud of, but now it just feels like I would be bragging to add it to an email signature that I feel is long enough. What are your thoughts on adding fellowship titles to your email sig?

 

Thanks!

My rule of thumb is to take the example of your mentors. 

Signatures are not CVs. They should reflect who you are and provide information that it would help your addressees respond better to your inquiry. Unless your fellowship come with an appointment, I wouldn't list them.
