Integrate $\Sigma \frac{1}{n!}\int z^{n}e^{1/z}dz$

2. Relevant equations

3. The attempt at a solution

Wrote out the first couple of terms, with $\frac{1}{z}=w$, making the integral $\Sigma \frac{1}{n!} (-w^{2-n}e^{w}+(2-n)(w^{1-n}e^{w}+(1-n)(w^{1-n}e^w)-(1-n)^2(w^(-n)e^w)...)$

But wasn't sure how to go from here.
