calculus - Convergence of $sumlimits_{n=1}^infty left(e^frac{1}{n} -1 -frac{1}{n}right)$

I've got in my assignment to show if the following series converges or diverges.

$$\sum_{n=1}^\infty \left(e^\frac{1}{n} -1 -\frac{1}{n}\right)$$

Attempt:

$$\begin{align*} \sum_{n=1}^\infty \left(e^\frac{1}{n} -1 -\frac{1}{n}\right) &=\sum_{n=1}^\infty \left( 1 + \frac{1}{n} + \frac{1}{2!n^2}+\frac{1}{3!n^3}+...-1-\frac{1}{n}\right)\\ &=\sum_{n=1}^\infty \left(\frac{1}{2!n^2}+\frac{1}{3!n^3}+...\right)\\ &=\sum_{n=1}^\infty \left(\frac{1}{n} + \frac{1}{2!n^2}+\frac{1}{3!n^3}+...\right) \end{align*}$$

At this point I'm lost. I tried using D'Alambert as follows:

$$\lim \frac{a_{n+1}}{a_n}=\lim\frac{\sqrt[n+1]{e}-1-\frac{1}{n+1}}{\sqrt[n]{e}-1-\frac{1}{n}}$$

which I tried to simplify with basic limit laws (hopefully correctly):

$$\lim\frac{\sqrt[n+1]{e}-1}{\sqrt[n]{e}-1} = 1$$

I don't know where to go from here. Thank you for all your help in advance.
