Make sure, you will have safe but usable e-mail address instead
Harvestors (bots) can see only bunch of code parts, thus cannot harvest your email addresses.
Once implemented, bots won't be able to gather the addresses at all. It will not be required to use (at) unprofessional chars.
Place the part of the code to any web page with support of HTML, CSS or JS.
The implementation is such quick, that it won't take pretty much none of your time at all.
