Hi Donna,
For default submit, InfoPath enforces one data connection. To work around this, change the Action to "Rules and Custom Code" and add a rule with two or more actions:
1. Double click on the button and change the dropdown from Submit to "Rules and Custom Code".
2. Click Rules.
3. Click Add.
4. Click Add Action.
5. Select "Submit using a data connection" from the Action dropdown.
6. Choose the first data connection that you want to submit to, for example "SharePoint submit".
7. Repeat step 4-6 for another submit data connection (for example "E-mail submit").
8. Click OK 3 times.
9. Preview form.
10. Click on button
11. InfoPath will sequentially submit to multiple data connections
Good luck!
