Full Guide On Mass Email Campaigns in 2024 [+Best Mass Email Service Platforms]

Initially viewed as an indispensable tool for mass communication, it eventually garnered a reputation for being somewhat outdated and less effective, particularly amid concerns over spam and the rise of social media marketing. However, declaring bulk emailing obsolete would be a hasty judgment. The strategy hasn’t died – it has metamorphosed.

Let’s picture this:

You’re a savvy marketer eager to connect with your audience and drive results. You’ve heard whispers that mass email campaigns are a thing of the past, but we’re here to tell you that they’re not just alive—they’re thriving. You get it right! They are alive and kicking. 

With the right approach, mass email campaigns can be your secret weapon, delivering personalized messages that resonate with your target audience and skyrocketing your ROI. Are you ready to supercharge your mass email marketing? Let’s start with some basics.

Mass email definition and short guide

Mass emails, often referred to as bulk emails, are a form of marketing communication that involves sending a single email message to a large group of recipients simultaneously utilizing BCC for mass email.

The traditional purpose behind mass emailing was to reach as broad an audience as possible with minimal effort and cost, usually for promotional or informative purposes. This approach typically involved generic, one-size-fits-all content, aiming to appeal to a wide array of individuals within a company’s database or mailing list.

However, the concept and practice of mass emailing have evolved significantly over time. With advances in technology and a deeper understanding of consumer behavior, marketers are now moving towards a more personalized and targeted approach to mass emailing.

Instead of sending the exact same message to all recipients, companies now use data analytics and segmentation techniques to tailor their emails according to diverse audience interests, behaviors, and preferences. This modern email mass marketing enhances engagement, effectiveness, and the overall perception of the emails, shifting from being seen as mere spam to becoming valuable and anticipated communications by the recipients.

What is the difference between an email blast, mass or bulk email?

While marketers often use the terms “email blast,” “mass email,” and “bulk email” interchangeably, subtle distinctions in their connotations exist that hint at the evolution of email marketing tools and strategies. Each term refers to the practice of dispatching a single email message to a broad audience, which can include both sales-qualified and marketing-qualified recipients.

In some cases, cold emails and mass emails are also lumped together, but they serve distinct purposes and follow completely different strategies. But to cut a long story short, check out our free guide on cold emails to maximize the effectiveness of your email marketing campaigns. 

However, we need to split the hair and discuss the nuances among them reflect varying degrees of sophistication, personalization, and strategic intent behind the mass communication efforts:

  • Email blast: Historically, this term has been associated with sending out a mass email to extensive lists, with speed and volume taking precedence over the relevance and personalization of the content. The notion of an “email blast” conjures images of indiscriminate sending, where messages are delivered regardless of the recipients’ individual interests or behaviors. This approach has often been criticized for its spray-and-pray nature, suggesting minimal engagement or genuine connection with the audience.
  • Mass email: The term “mass email” suggests a layer of strategy beyond the basic concept of an email blast. It implies that while the email is still sent to a large group, there is an element of segmentation or targeting involved. This means that even though one message reaches many, efforts have been made to ensure that the content is somewhat tailored or relevant to various segments of the audience. Thus, “mass email” carries a connotation of being both broad in scope and considerate in execution.
  • Bulk email: Similar to “mass email,” the term “bulk email” denotes the capability to send communications to a large number of recipients simultaneously. Yet, in modern marketing narratives, it also hints at the inclusion of customization and personalization strategies enabled by advanced email technology. Bulk emails today are characterized by the use of data analytics and segmentation, making it possible to address a vast audience with messages that feel personalized and relevant. This approach represents a move away from the generic casts of the past towards engaging significantly more effectively with the audience.

The current digital marketing landscape advocates a shift from traditional, undifferentiated email blast tactics to more refined, targeted, and personalized email campaigns. Despite the variability in terminology, the focus lies on enhancing the relevance and engagement of email communications.

By doing both cold emails and mass email campaigns, marketers not only achieve higher effectiveness in their campaigns but also foster stronger relationships between brands and consumers, thereby elevating the perceived value and impact of their email marketing efforts.

Mass emails ≠ Spam emails

Let’s address the elephant in the room.

The misconception is that mass emails are synonymous with spam. While it’s true that poorly executed mass campaigns can veer into spammy territory, a well-crafted and targeted email blast is far from junk mail. The key lies in understanding your audience, segmenting your list, and delivering value with every message.

In fact, according to a study by HubSpot, segmented email campaigns have an open rate that is 14.31% higher than non-segmented campaigns. By tailoring your content to specific groups within your audience, you can ensure that your mass emails are eagerly anticipated rather than promptly deleted or unsubscribed.

According to Statista, 45.1% of all email traffic is constituted by spam, with advertising efforts representing 36% of these unwelcome communications. But there is a golden stone—personalization. Sending out emails with personal names can significantly improve the open rate of your email campaigns. 

The shift from generic blasts to personalized, targeted approaches has revolutionized the email marketing landscape. By leveraging customer data, such as purchase history, browsing behavior, and demographic information, you can craft mass emails that feel like one-on-one conversations. Sending out an email with personal names not only improves engagement but also fosters a deeper connection between your business and your audience.

It doesn’t matter how good your template is or how personal your emails are, if your emails are destined to the SPAM folder.

Can I use Gmail to send mass emails?

For sure, you can use any email provider, and Gmail as well, to send mass emails. Still, there are a few important steps and considerations to keep in mind, especially given Gmail’s sending limits and best practices for mass emailing. However, Gmail could be the best way to send a mass email for free. Here’s how to address some of the key actions you mentioned:

How to create a mass email list in Gmail

To create a mass email list in Gmail, you essentially need to create a contact group (now called “labels” in Google Contacts). Here’s a simplified process:

  • Go to Google Сontacts: Open Google Contacts in your web browser.
  • Select contacts: Click on the contacts you wish to add to your email list. You can search for specific people or sort by criteria.
  • Create label: With your contacts selected, click on the label icon and choose “Create label”. Name your label; this acts as your email list.
  • Add contacts to the label: Once the label is created, your selected contacts will be added to this group.

How to create a mass email group in Gmail

Creating a mass email group in Gmail follows the same process as building a mass email list. Once you’ve created a label in Google Contacts or Google Sheets and added the desired contacts to it, you can easily send an email to this group by typing the label name in the recipient field of a new email in Gmail. All contacts under that label will be added as recipients.

How to delete mass email on Gmail

To delete mass emails in Gmail, you can use Gmail’s search and selection features:

  • Search: Use Gmail’s search bar to find the emails you want to delete. You can search by mass email sender, subject, or other criteria.
  • Select emails: Check the box at the top left corner above the email list to select all emails displayed on the page. If you have more emails than displayed on one page, you can click on the option to select all conversations with designated mass email senders that match your search.
  • Delete: Click on the trash bin icon to delete the selected emails.

How to send a mass email and hide recipients in Gmail

To send a mass email in Gmail while hiding the recipients’ email addresses, use the BCC (blind carbon copy) field:

  • Compose email: Open Gmail and click on “Compose” to start a new email.
  • Use BCC: Instead of adding recipients to the “To” field, click on the “BCC” field to the right and add your recipients there. If you’re emailing a group, you can type the label name here to send mass email without recipients seeing each other.
  • Send: Fill in the subject and body of your email, then send it. Recipients will not be able to see the email addresses of other recipients.

Can you send a mass email individually using Gmail?

Sending mass emails individually in Gmail requires a bit of creativity and a punch of true magic since Gmail doesn’t natively support sending individual emails without showing the addresses to a list of recipients in the same way that a dedicated email marketing tool or the Mail Merge feature in Microsoft Word does. However, you can use Google Sheets and Google Docs in conjunction with Google Scripts or third-party extensions to achieve similar results.

Can I use Outlook to send mass emails?

Like any other email platform, Outlook can be used to send mass emails. Here’s how to send mass email in Outlook individually:

How to send a mass email in Outlook

  • Create a new email: Open Outlook and start a new email by clicking “New Email”.
  • Add recipients: You can add recipients in the “To” field. If you’re sending to a large group and don’t need the email to be sent individually, you could add all the addresses here. For a more organized approach, especially if you plan to reuse the list, consider creating a contact group in Outlook beforehand and then adding that group to the “To” field.
  • Compose and send: Write your email subject and message, then send your email as usual.

How to send mass email in Outlook individually

To send mass emails in Outlook as if they were sent individually to each recipient (so they only see their own address), you can use the “Mail Merge” feature with Word and Outlook:

  • Start with MS Word: Open Microsoft Word and create a new document. Then, go to the “Mailings” tab and select “Start Mail Merge” > “E-mail Messages.”
  • Select recipients: Still, under the “Mailings” tab, choose “Select Recipients” and pick your list. You can use an existing list, select from Outlook contacts, or type a new list.
  • Write your email: Compose your email in Word. You can use “Insert Merge Field” to personalize the email for each recipient (e.g., by inserting their first name).
  • Finish & Merge: Click “Finish & Merge,” then select “Send Email Messages”. In the To field, choose the email field from your list. Set the subject line, select  HTML as the mail format, and click “OK”.

How to send mass email without showing addresses in Outlook

For sending a mass email without showing recipients, use the BCC field:

  • Compose a new email: Start composing your email in Outlook.
  • Use BCC: Enter all the recipient addresses in the “BCC” field. This way, recipients will see only their own email address and not the entire list.
  • Send your email: Complete your email and send it.

Is there a way to send a mass email individually in Outlook?

Yes, as mentioned, the most effective way to send a mass email individually in Outlook is through the “Mail Merge” feature, using Microsoft Word and Outlook together. This method allows each recipient to receive the email as if it were personally addressed to them, without seeing other recipients’ addresses. It’s especially useful for personalized mass email communications like newsletters, invitations, or updates, where personalization is key to engagement.

Remember, such email service providers limit the number of emails you can send daily to prevent spam, so for very large lists, you need to use the help of mass email service providers like Reply. Also, ensuring your communication complies with email marketing laws and guidelines, such as the CAN-SPAM Act, is crucial to avoid penalties and maintain your email’s reputation.

Can I use Salesforce for mass email?

Yes, you can use Salesforce for mass email campaigns, integrating it with various tools and platforms, including Google Sheets, to streamline your email processes. But still, Salesforce isn’t one of the dedicated mass email programs. It is a robust Customer Relationship Management (CRM) platform that offers comprehensive features for managing and executing mass email campaigns. Here’s how to send mass email in Salesforce:

Mass email from Google Sheets and Salesforce

While Salesforce does not directly integrate with Google Sheets for mass emailing, you can use third-party integration tools (like Zapier or Salesforce’s own Data Loader) to import contacts from Google Sheets into Salesforce. Once imported, you can leverage Salesforce’s email tools to send mass emails to those contacts.

How to send out mass email in Salesforce

Salesforce allows you to send mass emails to various segments, including leads, contacts, or custom lists. You can create personalized email templates, track the effectiveness of your campaigns, and manage your email lists directly within Salesforce. This functionality is particularly useful for businesses looking to maintain strong relationships with their customers through regular and targeted communication.

Mass employee email via Salesforce

For internal communications, Salesforce can be used to send mass emails to employees if their contact records are stored within Salesforce. This is beneficial for large organizations using Salesforce as their central CRM platform, ensuring that important announcements, updates, or company-wide messages are disseminated efficiently.

Mass unsubscribe from email and Salesforce

Salesforce includes features to manage email preferences and ensure compliance with email regulations, such as CAN-SPAM. Users can include unsubscribe links in their mass emails, allowing recipients to opt-out of future communications. Salesforce can automatically update contact records to reflect these preferences, maintaining the integrity of your mailing lists and minimizing the rates of mass unsubscribe from email.

Salesforce mass email limit

Salesforce imposes daily limits on the number of emails that can be sent through its mass email feature. As of my last update, the limit varies depending on the Salesforce edition and whether you’re sending emails to leads/contacts or using the “Send Email Through Salesforce” functionality.

The limit can range from 1,000 to 5,000 emails per day for most standard Salesforce editions. It’s important to note that these limits are subject to change and can be different based on your specific Salesforce configuration or any additional email management features you might be using.

Avoiding mass email fails

Not all mass email campaigns are created equal. Some fall flat, failing to engage subscribers and drive results. To ensure your campaigns don’t end up in the digital dustbin, it’s crucial to understand the common pitfalls that lead to unsuccessful mass emails:

Lack of segmentation

Sending the same message to your entire list is a surefire way to miss the mark. By failing to segment your audience based on their interests, behaviors, and preferences, you risk sending irrelevant content that fails to resonate.

Poor list management

A healthy email list is the foundation of a successful campaign. Neglecting to regularly clean your list of inactive or invalid addresses can harm your deliverability and reputation.

Ignoring personalization

In an age where consumers expect tailored experiences, generic mass emails simply won’t cut it. Failing to personalize your content, subject lines, and calls-to-action can lead to disengagement and unsubscribes.

Skipping on A/B testing

Before hitting “send” on your mass email, it’s essential to test every element, from the subject line to the layout and functionality. Neglecting to test can result in embarrassing mistakes or technical glitches that undermine your campaign’s success.

Сut back on an SMTP server for mass email 

Setting up an SMTP server for mass email campaigns is a crucial step in ensuring the efficient and reliable delivery of your emails. However, when it comes to sending mass emails, there are specific considerations to keep in mind to maintain high deliverability rates and comply with anti-spam regulations.

By understanding and avoiding these common pitfalls, you can craft mass email campaigns that actually resonate with your audience and drive meaningful results. But how to refine your mass email campaign and maximize its potential?
