Email broadcasting: what an email broadcast is, types and how to send one
One message for your whole list: when to use it and how to get it opened
Email broadcasting is sending the same email to an entire subscriber list, or to a segment, at the moment you choose. Each email of this kind is called an email broadcast.
It is the classic way of doing email marketing: you prepare the campaign, choose who it goes to and send it or schedule it. A newsletter, a sale offer or a webinar invitation are all examples of a broadcast.
What does broadcasting mean?
Broadcasting means transmitting the same content to a wide audience. It is the term used for radio and television: a single transmission that reaches many people at once. A broadcast is the transmission itself.
In email marketing the idea is the same: one sender, one message and many recipients. It is also called mail blasting, mass emailing or simply a campaign. An email blast is a send that goes to the entire list, without segmentation.
The term is also used on other channels. On WhatsApp, for example, broadcast lists send the same message to several contacts at once.
How do you send an email broadcast?
These are the five steps of any send:
Choose the list or segment. Decide who receives it: the whole list, a group of customers or subscribers in a specific area.
Create the email. Write the subject line and preheader, design the message and add a clear button.
Run a test. Send it to yourself and check the links, images and mobile version.
Send or schedule. Choose the day and time when your audience usually opens their email.
Measure the results. Review opens, clicks, unsubscribes and complaints to improve your next send.
What is the difference between a broadcast and an automated email?
You send this type of email yourself, to many people at once and on a specific date. An automated email goes out on its own, to each person, when they do something: subscribe, buy or abandon a cart.
| Email broadcast | Automated email | |
|---|---|---|
| When to send it | On the date you choose | When the contact does something |
| Who receives it | The whole list or a segment, at the same time | Each contact, individually |
| How often | Once | Every time the condition is met |
| Examples | Newsletter, offer, invitation | Welcome, abandoned cart, birthday |
| Tool | Campaigns | Autoresponder or marketing automation workflows |
The two complement each other. Automated workflows accompany each contact, while campaigns keep the relationship with the whole list alive.

Types of email broadcast
These are the most common sends of this kind:
| Type | What it’s for | Example |
|---|---|---|
| Newsletter | Keep in touch regularly | A monthly newsletter with industry news |
| Offer or promotion | Sell on a specific date | 20% off during the sales |
| Launch | Introduce a new product or service | “Our new collection is here” |
| Event invitation | Get attendees | A webinar or a store opening |
| Educational content | Provide value and build trust | A guide or the latest blog posts |
| Company news | Announce changes | New opening hours, prices or service |
| Important notice | Communicate something urgent | An incident or a change in terms and conditions |

Tips for sending an email broadcast
Segment whenever you can. The same email for everyone performs worse than a tailored one. Segmentation increases clicks and reduces complaints.
Take care with the subject line. It decides whether the email gets opened. Try two versions with an A/B test before sending to the whole list.
Choose the right moment. Check your statistics to see when your subscribers open their emails and schedule the send.
Keep a steady frequency. Not so rarely that they forget you, nor so often that they get tired of you.
Comply with Gmail and Yahoo. If you send in volume, you need SPF, DKIM and DMARC, one-click unsubscribe and a low rate of spam complaints.
Clean your list. Stop sending to people who haven’t opened in months: it improves your reputation and your results.

Email broadcasting, email blast and bulkmail
These terms are used almost as synonyms, but there are nuances:
Email broadcasting is the general term for any send of the same email to many recipients.
Email blast usually refers to a send to the entire list, without segmentation. It has a somewhat negative connotation.
Bulkmail focuses on volume: thousands or millions of emails sent with a specialized platform.
