Sending cold emails can be nerve-wracking, but Mallory Contois credits them with launching her career.

Over her 15-year career working with startups, cold emails have helped her find jobs, make connections and launch new ventures like her popular networking community Old Girls Club.

In fact, a cold email landed Contois her current role as vice president of growth at Maven, an online learning startup – a position that was created just for her, she says, after pitching herself to the company.

Contois wasn’t always this outgoing. But when she was 25, she was diagnosed with non-Hodgkin’s lymphoma, an experience that “really changed” her mindset, she says.

“For me, going through that health crisis really just opened a new reality,” Contois says. “No one’s going to be upset at me for asking for help. The worst thing that happens is they don’t respond, or they say they can’t help me.”
