What is an email blast?

An email blast (or e-blast) is a single email sent to a large list at the same time, usually with little or no segmentation. Marketers use blasts for announcements, promotions, and newsletters.

The name says it all: one message, fired at everyone at once.The recipients are not typically targeted in a strategic manner—hence why it is referred to as a "blast" and frequently associated as a spammy email.

Email blast definition: to send one email to many people without strategy or segmentation.

Blasts work. They’re cheap, fast, and reach your whole list. But the word blast suggests zero targeting, and that’s exactly how recipients experience a bad one. Sending to your whole list is fine. Twilio SendGrid handles sends like that every day. The trick is making a big send feel like it was written for each reader.

How to send an email blast

First, choose an email service provider. You won't be able to get the appropriate segmentation and timing without one. Then, import your permission-based list and segment it. Now, you're ready for sending an email blast (the right way).

1. Stop calling it an email blast

Take a step back before sending your next email campaign. Think about the meaning behind the email blast.

Does getting blasted with email (or anything for that matter) sound like a good experience? This tip should lay the foundation for how you should think about your email marketing campaigns during the conception phase of your email marketing strategy.

Consider and respect your email subscribers’ time and interest in your brand, and always keep them front of mind when you are designing campaigns. You’re not blasting your recipients—you are providing them with valuable content that may persuade them into paying your brand money.

Did they subscribe to your email newsletter or new product updates? Then don’t call it an email blast—call it your email newsletter campaign or product newsletter.

I, personally, don’t want to be part of any brand’s email blasting strategy—I’d unsubscribe in a heartbeat.

2. Use an email service provider

Now that you’re creating email blast campaigns designed to benefit, not irritate, your recipients, you’ll need to verify that your email reaches their inbox and isn’t getting sent to the spam folder or bounced entirely. Email Service Providers (ESPs) reduce the hassle related to email delivery so you can focus on your campaign’s content and strategy.

The larger your list grows, the more important it is to rely on dependable and fast ESPs. ESPs also monitor the IP that you send email from and let you know if something is up and may be affecting your email deliverability.

From the get-go, you might send email blasts to learn more about your audience. Once the data starts rolling in, you can begin segmenting your recipients into different lists based on their behavior (more on that soon).

Email service providers can also provide you with:

• Pre-built email templates
• Landing pages
• Drag-and-drop design editors
• Email automation tools
• Digital marketing tools
• Customer relationship management (CRM)

3. Send to a clean email list

By now it should go without saying—but it’s always worth reemphasizing—any email list you haven’t built with permission marketing tactics jeopardizes your ability to send any email at all (not to mention it kills your relationship with your recipients).

SendGrid doesn’t allow customers to send email to purchased email lists. This protects you and everyone who uses SendGrid to send email. For strategies on list building, read How to Build an Email List From Scratch.

4. Personalize your list with segmentation

A pillar of content and copywriting is to write as if you’re speaking to one single person at a time. This isn’t feasible with mass email marketing, but segmenting your list and messages helps attain the same sort of feeling. Email marketing segmentation transforms generic emails into personalized and tailored messages more likely to resonate with your recipients.

It doesn’t matter if you’re a huge ecommerce brand, small business, or a local mom-and-pop shop—the way you speak to your customers matters.

Luckily, it’s never been easier to accomplish this. Modern email marketing software allows you to efficiently segment your messages to recipients based on a number of factors and metrics, such as:

• Age
• Gender
• Region
• Past email
• Open rate
• Click-Through rate
• Conversion rate

Use A/B testing to see what resonates most with your audience. Creating multiple email subject lines and content with different email designs automatically shifts it from a blast to a more personalized experience.

Start segmenting from the get-go with a well-designed welcome email.

Twilio SendGrid offers all of these segmentation capabilities in our own email marketing tool, Marketing Campaigns. If you're interested in learning about how to leverage your segmentation with automation, try out SendGrid's Marketing Automation tool.

5. Include a clear call to action

If you’ve managed to convince your recipient to open one of your promotional emails, nice work. Take 3 seconds to celebrate. But this is only the start. What are you asking them to do once you’ve grabbed their attention?

Without a compelling call to action (CTA), all your effort and planning will sadly be for nothing. How you craft your CTAs will depend on the action you want the recipient to take. And yes, there’s a guide for creating strong email CTAs. Download it here.

6. Authenticate your domain

In 2024, Gmail and Yahoo starting enforcing bulk sender rules. If you're sending more than 5,000 emails a day (easy to do with blasts), then you'll need:

• Authentication: SPF, DKIM, and a DMARC policy on your sending domain.
• One-click unsubscribe: A visible unsubscribe link plus the one-click unsubscribe header, with requests honored within two days.
• Low spam complaints: A spam complaint rate under 0.3%. Lower is better.

Miss these, and your emails might not even make it to even the spam folder.
