How to create an email blast

Email blasting is a powerful tool for any organization. It allows you to quickly and effectively communicate with your supporters to promote action.

Learn how to create a blast – add recipients, choose a theme, and enter content. Preview your blast before sending or schedule it for a later time.

Create a blast

1. Select the Broadcaster you want to use to send the blast. Click “Email.” You will see a list of previously drafted and sent emails, if any exist. Select “New blast.”

2. Enter a slug and description. A slug is the name of your email. Leave an optional short description or note in the “Description” text box.

3. If you are including links to your website in your blast, consider checking the provided checkbox. When checked, forms on your website will auto-populate with information from the recipient’s profile. This could increase the number of people who complete the form, but could cause confusion if the email is forwarded to another recipient. 

For example, you send an email blast with a link to your website's online petition. When Jane Doe opens your email and clicks on the link to sign the petition, the form will already have her name and email fields filled out. She only needs to click "Sign petition" in order to take the action.

Alternatively, you may choose “All” and select all supporters in your nation, or all prospects. Remember that it is good practice to segment your email list in order to increase your email deliverability.
