E, you might want to consider something similar for the "Welcome" email problem. Create an email work order queue table in the database for welcome message emails and limit the server to only being able to send a certain number of them over specific periods of time (say only 10 every hour or whatever works). That way, if load gets too high, then it will only send a fixed amount of welcome messages and the rest will fall into the queue and be processed later when load lessens and the queue starts freeing up. Alternatively it could hold ALL welcome messages in the work order queue during peak hours or show days and only send them during off peak times (weekends or 4AM for instance) You know when those times are better than I.
