It is permissible to send "mass emails" (my company does it), but I'm not sure what the limits are. It also depends on what your definition of "mass" is. There will be limits for total allowed to send and total allowed to send per minute/hour.

This might get you started, and I'm sure there are other solutions in this forum that could be found with a simple search.
