2. On the next page, select "Save as a Template."
3. Once saved, click the back button in the upper left of the screen (next to your email blast title). Then click the back button in the bottom right of the screen.
4. Then click '+ New Blast' to create a new email blast. Make sure to select the template you created and then click '+Create Blast' in the bottom right.
5. Next, navigate to the Recipients tab to add your recipients manually, upload a CSV file of your recipients, or choose from an existing Contact list. Please refer to this support article if you have questions about adding a Contact list.
