Want to learn how to send a mass email to your audience? You’ve come to the right place.

You know how to communicate with customers in the information age: SMS, social media, and, above all, email. Email communications inform customers about promotions and get them interested in new offerings from your brand.

It’s relatively easy to deploy, affordable, measurable, and effective at fostering long-term engagement.

Mass emails (or bulk emails) are the primary method of email marketing—aside from order confirmations and other individually tailored communication triggered by specific customer activities. For instance, you might send customers a mass email for upcoming event awareness or to alert them to seasonal sales.

Want to send a mass email and don’t know where to start? We’ve put together a brief guide explaining how to send mass email in 6 steps. Following this guide will ensure your messages land in your desired recipients’ inboxes without fail. 

What is a mass email?

A mass email refers to a single email message that is sent to a large group of recipients simultaneously. It’s sometimes called an email blast.

These emails are typically used for communication, marketing, or informational purposes. You often send them to a wide audience, such as your customer base, subscribers, or a list of contacts.

However, just because it’s a “mass” email doesn’t mean that it’s not segmented. You should still use some degree of segmentation and personalization to reach your intended audience and boost engagement.

Mass emails can be used to share announcements, promotions, newsletters, updates, event invitations, or any other type of content that is relevant to the recipients.

Mass emails are commonly managed through email marketing platforms (like Twilio SendGrid) to allow your businesses to personalize the content, track open rates, measure click-through rates, and manage unsubscribes.

How to send a mass email

1. Find an email service provider

Before you can send your first email, you’ll need to find an email service provider (ESP) that can meet your deliverability expectations and handle the volume of email you want to send. An effective bulk email delivery service has the power to deliver emails at scale without substantial delays.

As an industry leader, Twilio SendGrid sends over 10 million messages a month. So whether you need to send 100 emails a month or 10 million, we can help you optimize your email delivery rates and scale your email program—check out our custom pricing based on your email sending volume or business needs.

2. Get a dedicated IP Address

While you can get by using a shared IP address if you only send a few thousand emails a month, you’ll need to up your game if you plan to send hundreds of thousands of emails (or more) a month. Sharing an IP address can hurt your reputation if another sender using the same IP doesn’t send responsibly. That’s why owning and controlling a dedicated IP address(es) is a must to protect your reputation as you scale.

3. Create an email list

Next, you need to know who you want to receive your message. An ESP like SendGrid can help you build your email list and grow your business with simple sign-up forms placed directly on your website. 

Just remember that no matter how easy and tempting it might seem, never buy an email list. Purchased email lists won’t help you achieve your marketing goals because the users aren’t expecting to hear from you—and may not want your emails.

Not only will purchased email lists experience poor recipient engagement, but these also damage your sender reputation, impact your sender score negatively, and can get your email account shut down potentially. Again, never buy an email list.

To grow your email lists the right way, create multiple ways for individuals to sign up for your emails, optimize your opt-in pages, and provide an email preference center for subscribers to determine the types of messages they want to receive from your brand and how often they receive them. 

4. Draft the content of your bulk email

Now it’s time to determine what you want your email to say. At SendGrid, we like to put ourselves in our customer’s shoes, so before you draft your email copy, consider what value your email has for recipients—or why they should want to receive your messages. 

If you were a customer, would this email be valuable to you? Thinking about your email from your customer’s perspective can help you tailor your tone, copy, and content to your recipients’ interests better, which can help increase your engagement.

Here’s what you’ll need to include in your email copy draft: 

Of course, you can always choose to use a plaintext email as well. 

However you decide to format your message, ensure that every email you send has one clear call to action (CTA). Multiple CTAs confuse your readers, so your CTA needs to detail the next step you want your recipients to take, like downloading an e-book, browsing your newest products, or shopping for your latest sale.

For instance, let’s say you’re drafting a mass email for upcoming event awareness. Include all the vital details—what the event is and when and where it’ll happen. Also, include a form for customers to RSVP. It’s common sense and effective.

5. Start small and work your way up

Unfortunately, you can’t just dive right in and start sending a million emails a day. So before you can start sending bulk emails, you need to warm up your IP address and sender domain to prove to internet service providers (ISPs) that you’re a reputable sender.

How do you kick off the process of warming up an IP for large volumes of email traffic? Start by sending a small number of emails and increasing gradually in volume. You’ll also want to monitor your lists as you go, removing any unengaged or invalid contacts to increase the likelihood of your recipients opening and clicking your messages. 

If you have strong engagement and few spam complaints, you can continue to slowly increase the number of emails you send over time until you reach your desired volume. The key is patience and consistency. Focus on producing good emails and sending them to an audience that will find them relevant.

And there you have it! Now you know how to send bulk email blasts successfully. But before you press Send, keep these additional points in mind to avoid making the most common mistakes—you don’t want to depress engagement and fall into the same traps.

The most important thing to remember is not to send too many emails because the more emails you send, the fewer returns you’ll see. Customers might even relegate your emails to the spam folder, which is the last thing you want.

6. Use an appropriate follow-up method

Once you’ve sent out your bulk email, stay on top of your sales funnel and ensure customers follow through on the offers. 

However, your sales funnel doesn’t have to be a complicated web. It can be pretty straightforward: Where are your various customers engaging with your brand, and what steps do you need to take to bring them further along?

Also, consider which methods might be most effective for keeping in touch with consumers after an event concludes. Email is certainly one way to continue the conversation with customers, but in some cases, it may make sense to target individuals across channels, including social and text marketing in your strategy. 

Remember, even though you’re sending many emails, taking the time to track individual preferences and email engagement levels can help you get the most out of your mass email campaigns long term.

Pros and cons of mass email campaigns

Mass email campaigns, like any marketing strategy, come with their own set of advantages and disadvantages. They should be a powerful part of your email marketing program, but they have a special time and place.

Here are some pros and cons to consider:

Pros of mass email campaigns:

  1. Wide reach: Mass email campaigns allow you to communicate with a large audience quickly and efficiently.
  2. Cost-effective: Sending emails is generally more cost-effective than traditional advertising methods.
  3. Personalization: While mass emails are sent to multiple recipients, you can still personalize the content using recipient names, segmentation, and dynamic content, making the messages more relevant and engaging.
  4. Analytics: Email marketing platforms provide detailed analytics, allowing you to track open rates, click-through rates, conversion rates, and other metrics to measure the effectiveness of your campaign.

Cons of mass email campaigns:

  1. Deliverability challenges: Mass emails can sometimes be flagged as spam or end up in recipients’ spam folders, affecting deliverability and visibility. You’ll want to properly warm up your IP and follow email-sending best practices.
  2. Unsubscribes and opt-outs: Some recipients may choose to unsubscribe from your emails (especially if they aren’t personalized or segmented enough), reducing your overall reach and potentially impacting your sender reputation.
  3. Content overload: Your message might get lost among other emails (especially if you send automated messages, newsletters, and other campaigns), leading to lower open rates and engagement.
  4. Segmentation complexity: Properly segmenting your email list and creating targeted campaigns can be time-consuming and requires a thorough understanding of your audience.
