$S_n=\displaystyle\sum_{k=1}^n\frac1k$

You have

$\ln e^{S_n}=S_n\ln e=S_n$

so showing that $e^{S_n}>n+1$ amounts to the same as showing that $S_n>\ln(n+1)$ .

As $n\to\infty$ , you have $\ln(n+1)\to\infty$ . By comparison, then, it follows that $S_n\to\infty$ at a faster rate, which means $S_\infty$ must diverge.
