If you want to use SugarCRM’s email marketing features, the first 
step is to create Target Lists containing all of the people you would 
like to receive your email. You can use the built-in querying tools of 
SugarCRM – search and reports – to identify your recipients by any 
characteristics stored in your database.
First, take a few moments to decide who you would like to target with
 your next email message(s). Then, think about how you could identify 
these targets using characteristics stored in your database. For 
example, we recently invited all of our SugarCRM customers to attend a 
webinar about the release of SugarCRM version 7.0. We identified these 
recipients because they are attached to Account records classified with a
 type of customer and a sub-type of SugarCRM. As you think about 
identifying your targets, feel free to consider standard and custom 
fields, as well as fields stored in related modules.
Once you have identified the characteristics of your targets, 
determine whether you should use search or reports to make your list. 
Are all of the characteristics available on a single advanced search 
screen? Great, use search! Otherwise, use report filters to search by 
any field in your database.
If you are using search, select your desired characteristics and  click Search. Then, use the checkbox tool to select all of the results.  (Be careful to select all, and not just the first page.) Then, use the  action button to add the selected records to a Target List. In the  pop-up window, create a new target list and then select your new list.
 If you need more advanced searching capabilities, create a Rows and Columns report instead. Use the filtering capabilities  to search by any criteria needed, including fields in related modules,  custom fields, and combinations of and/or logic. Once your report is  ready, go to the Target Lists module and create a new Target List. On  the appropriate subpanel, i.e. Contacts or Leads, select the option to  “Select from Reports”. Choose your report, and everyone listed in the  report will be added to your Target List. 
 SugarCRM makes it easy to create target lists and target segments of  your database using the available querying tools that you already use  throughout the system. One caveat: target lists in SugarCRM are not  dynamic. That “SugarCRM Customers” target list you made 2 months ago is  not going to include any of your new customers. You’ll have to manually  update your list using search or reports, or create a new list, when you  want to use it again.
