Is Bulk Emailing Useful and Worth the Attention?

Is bulk email marketing becoming obsolete? Absolutely no.

Mass emails are typically sent to an unfiltered contact list who may or may not be interested in what you offer. Customers today expect personalized emails with information and unique offers tailored to their needs. As a result, marketers are turning to email automation and personalization to send bulk emails and fulfil their marketing objectives.

According to a McKinsey study, emails are 40 times more effective than social media at acquiring new clients.

In the last decade, especially after the pandemic, bulk email marketing has come a long way. Previously, opening and viewing emails required a desktop, but today we have mobiles that readily provide people access to emails.

  • 1.7 billion individuals use their mobile phones to send emails. With so many people using their phones to check their email, it’s no surprise that the number of emails opened on mobile devices currently accounts for 60% of all email engagement.
  • For 85% of users, smartphones have become the primary device for checking email. That rate is much greater for individuals aged 25-34, at 90%.

Therefore, bulk email marketing campaigns’ impact on your business is immense. It quickly reaches a broad segment of the audience, irrespective of where they are, what they do or which device they use to access their emails.

Today’s bulk email marketing strategy uses machine learning and automation to provide personalized information at scale. People are tired of hearing duplicate old emails. Thus, personalization and relevancy are now the top priorities. A marketing campaign’s visual diversity and accessibility are crucial to its success.

You can still send bulk emails to your list, but dynamic content tools allow you to substitute specific portions of a bulk email with content that varies depending on the recipient.

Challenges with Mass Emails

Deliverability: Ensuring that bulk emails reach the intended recipients’ inboxes can be a challenge. Factors such as spam filters, email reputation, and authentication protocols play a crucial role in determining deliverability. 

Email List Management: Managing a large mailing list requires careful attention to maintain its quality and relevance. It’s essential to regularly update and clean the email list to remove invalid or inactive addresses. Segmenting the list based on user preferences and engagement levels helps in targeting specific audiences and increasing campaign effectiveness.

Personalization: Personalizing bulk emails is key to engaging recipients and driving conversions. However, tailoring each email to individual recipients can be a daunting task. 

Email Content and Design: Creating compelling and visually appealing email content can be a challenge, especially when dealing with a large volume of emails. Bulk email service providers often offer customizable email templates and drag-and-drop email builders to simplify the process. 

Email Tracking and Analytics: Tracking the performance of bulk campaigns is essential for evaluating their effectiveness. Metrics such as open rates, click-through rates, and conversions provide insights into audience engagement and help optimize future campaigns. 

Compliance with Regulations: When sending bulk emails, it is crucial to comply with relevant regulations, such as anti-spam laws like CAN-SPAM or GDPR. Adhering to these regulations helps maintain a good sender reputation and ensures legal compliance. 

Reputation Management: Building and maintaining a positive email sender reputation is vital for successful bulk email marketing. High bounce rates, spam complaints, or being identified as a source of spam can negatively impact deliverability. Choosing a reliable bulk email service provider like Mailercloud, which actively manages sender reputation, can help maintain a good standing and ensure high inbox placement rates.

What’s the best time to send a bulk email campaign?

Determining the optimal time to send a bulk email is crucial for maximizing its impact and engagement. While there is no one-size-fits-all answer to this question, several factors can help guide your decision. Consider the following aspects when deciding the best time to send a bulk email:

  1. Understand Your Audience: Take the time to understand your target audience’s preferences and behaviours. Analyze their demographics, geographic location, and time zones. This information can provide valuable insights into when they will most likely be active and receptive to your emails.
  2. Test and Analyze: Conduct A/B testing by sending your bulk emails at different times and days of the week. Track the performance metrics for each test group, such as open rates, click-through rates, and conversions. Analyzing the results will help identify patterns and determine the optimal time for your specific audience.
  3. Consider Industry Standards: Research industry benchmarks and best practices for email marketing. While these standards can serve as a starting point, remember that every audience is unique. Adapting and tailoring your strategies based on your specific audience’s behaviour is essential.
  4. Time Zone Considerations: If your audience is spread across different time zones, segment your email list and schedule email sends accordingly. This ensures that recipients receive your emails at a time that is most convenient for them, increasing the chances of engagement.
  5. Experiment and Iterate: The optimal time to send bulk emails may evolve over time as your audience and their preferences change. Continuously monitor the performance of your campaigns, and be open to adjusting your email schedule based on the insights you gather.
  6. Leverage Automation: Utilize email marketing automation tools provided by bulk email service providers like MailerCloud. These tools allow you to schedule emails in advance, ensuring they are delivered at the desired time without manual intervention.

Remember that the best time to send a bulk email may vary depending on your industry, target audience, and campaign goals. Regularly evaluating the performance of your emails and making data-driven decisions will help you refine your approach and achieve better results.

How to Send Bulk Emails without Spamming?

The main reason why marketers sometimes dread bulk emailing is that there are high chances of them getting flagged as spam. However, if you know what are the main reasons behind it and take some mindful action while creating and sending bulk emails, you can easily achieve high email deliverability rates.

Reasons why bulk emails may land up in the spam folder

1. No permission from the email recipient to send email

Getting permission from the recipient is the best approach to ensure that your bulk emails do not end up eventually in the spam folder. This indicates that you respect the recipient’s privacy and ensures that you are only sending emails to people who have expressed an interest in hearing from you. Emailing people without authorization is against all major email marketing platforms’ acceptable usage policies. As a result, you may be banned from these platforms as well.

2. Subscribers no longer remember you or your business

Internet service providers (ISPs) follow a simple rule for marking your emails as spam: if the email recipients mark your email as spam, ISPs will also mark them as spam over time. Any next email you send will go straight to the spam folder once the spam complaints reach a particular threshold.

The question now is why would someone who has given you permission to send them emails mark it as spam?

The reason is straightforward: they have forgotten who you are and are unaware of your business. They have no recollection of signing up for your newsletters. Perhaps you’ve given up on email marketing and are now attempting to revive it. However, those who joined the email list a year ago are likely to have forgotten about you, leading them to believe your email is spam.

To avoid this, make sure your branding is clearly evident in the email. The name of your company should be visible so that the receiver knows who sent the email. Your “from” address should be a name they are familiar with.

3. Poor engagement rates

When it comes to spam filtering, ISPs consider email engagement rates as the basis to make this decision. You risk being reported as spam if your email open rates are low or if the majority of your emails are deleted.

The ideal way to boost the chances of landing your emails in the inbox is to improve the email engagement rates.

  • Craft amazing and click-worthy email subject lines.
  • Work out the optimal email delivery time and frequency in tune with your target audience’s behavior and receptivity.
  • Tactfully implement email personalisation.
  • Create segments of your contact list and send relevant emails.

4. High complain and bounce rates

A high bounce rate (more than 4%), on the other hand, usually indicates that the email list is old, of poor quality, or bought from random web sources. ISPs treat such senders badly, and their reputation suffers as a result.

The majority of email services allow users to flag emails as spam. If there are too many complaints reported, the email may be filtered away. Your complaint rate should ideally be less than 0.1 percent, or one out of every thousand recipients. This number is automatically recorded and displayed by most email marketing services for all senders in the same domain.

5. Unclear ‘From’ address

When the ‘from’, ‘to’, or ‘reply-to’ information is imprecise or deceptive, this is also regarded as a serious act of email spamming. Keep in mind that such behavior will automatically filter your email and mark it as spam.

To avoid all of these situations, include your or your company’s name in the ‘reply from’ section of the email, so that your subscribers may readily remember it for future communications. It would be easier for your subscribers to recall if you use the same name for all campaigns. You can use either your complete name or the name of your business, or a mix of both.

Strategies for Bulk Email Delivery without Spamming

  • Regularly clean your email list to delete obsolete, stale and inactive contacts.
  • Maintain a balanced image to text ratio in the emails. Avoid sending emails which contain only images.
  • Do not create any deceptive or faulty email subject lines.
  • Follow the best HTML practices in the emails.
  • Include an easy-to-find unsubscribe link in the emails.
  • Optimize the email content to improve its accessibility and readability across different screen sizes.
  • Organically build your email list.
  • Conduct rigorous spam tests before sending bulk campaigns.

Best Email Marketing Practices

Determine who is your target audience.

Marketers should identify which demographic groups are most interested in their business’s products and services. Before establishing a bulk campaign, consider factors such as location, interests, age groups, gender, culture, and other demographic traits. The goal is to personalize marketing emails for each category of the target market.

Concentrate on the benefits.

Clearly state in your bulk campaigns what your subscribers will gain from using the products and services offered by your business or from the emails they are going to receive from now onwards. You can easily drive the customers to respond by highlighting their interests in the bulk campaigns and how your business offerings resonate with their interests and choices. A good bulk emailing tool scales with your business, offering different thresholds such as 25,000, 100,000, or even 1,000,000 emails per month.

Keep the emails short, crisp and free of bluff.

A marketing email should be brief. This way, the email recipient will be able to notice the important information quickly enough to make a decision. When reading long or intricate emails, most individuals lose the plot. Worse, such emails might be deleted immediately after being opened. As a result, marketers should create succinct emails and deliver information that focuses on a certain brand’s product offerings as well as on the recipients’ problems and needs.

Offer exclusive discounts and deals.

Marketers could tempt email recipients by offering them special offers that are only accessible to them.

Clearly make the deadlines known to the audience.

Mention the offer’s expiration date to emphasize the need for a quick response. Customers will be deterred from procrastinating, which can lead to forgetfulness, as a result of this.

Provide enough lines of communication.

Allow customers to respond to your emails. For example, a marketer can provide a phone number, a URL, or other information that allows a potential consumer to easily contact the email sender with any questions.

Features to look for in a Bulk Emailing Tool

Testing and Optimization Supporting Functionalities

  • Clickthrough rates: A good clickthrough rate will be in the range of 2 to 5%.

  • Spam complaint rates: Below 0.1% of spam complaints can be considered as acceptable.
  • Unique opens
  • Click to open rates

  • Targeted personalisation, according to 74% of marketers, boosts customer engagement.

Drag and Drop Email Builder

Drag and drop email builders make the process of creating engaging and on-brand emails easy. You can drag a component from the sidebar, such as an image, quotation, or button, to a part in your email using this simple function. This can help you save time as you figure out the ideal email flow for bulk emailing and move things around.

High Email Deliverability Rates

Imagine spending a lot of time and effort on an email campaign that never reaches the inboxes of your readers. Isn’t it terrible?

That’s why it’s critical to double-check your bulk email service provider’s delivery rates to ensure that your emails reach all of the contacts in your email list. To accomplish this, it must perform numerous technological tasks on the backend. The delivery rate of a decent bulk email software should be higher than 90%.
