Sending Mass Emails From Salesforce

Image
Create a Email Template  Then you either go to the Lead Tab or the Contact Tab and scroll down the page until you see the Mass Email link in the Tools section. On the first step of the mass email wizard is to create your target list. To do this you have the option of leveraging an existing View that is available on the Leads tab, or you can create a new View from within the wizard. In this example we will create our target list from within the wizard by clicking the   Create New View   link. In my example I’m   creating a quick View   to grab any Lead that is in the State of California. Notice in Step 2 of the View you can use a Campaign to filter (handy if your Campaign has your target list as Campaign Members!).

Spring Batch 2.0 -Basic Concepts

There is always a healthy debate when talking Java and batches. When I heard  Spring Batch , I had to try it out.  On a previous project, many eons back, I did some batch processing in Java. What hurt me there (after a lots of optimizations) was a call to another persons module. His module happily loaded up an entity bean. You can guess where that ended. Next release I went through the code and replaced the entity bean calls with ONE update SQL statement. That fixed things. I was processing 200k records in 15-20 minutes, with an extremely small memory footprint. Even this I could reduce further if I tuned another module. But the performance was deemed enough and we moved on. What I personally felt from that experience was the need of a decent Java-based Batch processing framework. Of course having this does not mean use Java for batches. Sometimes for bulk processing doing it in the database may be the right approach. In this blog I want to go over Spring Batch processing. We wi
