What is a mass email?

A mass email, also known as a bulk email or email blast, is an email campaign sent to a large list of recipients.

Mass email marketing is typically used to promote a brand, product or offer at scale. It can also be used to nurture relationships with new and existing customers over time.

Some common types of mass emails include:

• Newsletters. Keep subscribers up to speed about the business, including insights, guides or notifications.

• Promotional emails. Promote your sales, attract customers, suggest products to prospective and existing customers and build brand awareness.

• Retention emails. Boost brand loyalty and keep long-term customers engaged.

• Acquisition emails. Convince potential customers to make a purchase and generate sales.

It’s possible to send mass emails for free using tools like Gmail, but those workarounds come with limits around volume and deliverability.

Most growing teams eventually turn to dedicated mass email software for tracking, automation and support with larger lists.

6 best mass email software solutions for sending bulk messages

A great mass email service will allow you to track your emails, monitor your open, engagement and email delivery rates, automate follow-ups and control the entire campaign from one spot.

Here are our picks for the six best mass email senders.

1. Pipedrive

Pipedrive is an intuitive CRM with built-in mass email functionality, ideal for teams that want a full suite of features and powerful integrations to boost sales and marketing efforts.

Because emails are tied to contacts and deals, you can segment your mass email lists based on real-time pipeline data and see how emails affect responses and deal progress.

With email automation and contact management, your sales team can easily follow up at the right time and keep communication organized as your list grows.

2. Campaigns by Pipedrive (paid add-on)

If you want to go beyond simple sends, Pipedrive also offers its Campaigns email marketing platform as a paid add-on.

This specialized tool is designed for more structured mass email campaigns and in-depth insights.

Add engaging touches to dynamic content in your high-volume emails, warm up a new domain quickly and increase deliverability with this handy platform.

What to consider when choosing a mass email service

The right software for bulk email marketing should support how your team works today and scale with you as your list grows and your business goals take a new direction.

Below are several factors to keep in mind when choosing a mass email platform.

• Ease of use: Hard-to-use tools can hinder campaign effectiveness. Look for a user-friendly platform with features like content blocks, customizable templates and drag-and-drop editors that make building, sending and updating campaigns simple, even for non-technical users.

• Core features: At a minimum, you need list management, campaign creation, automation and reporting. Avoid paying for extras and advanced features you won’t use, but don’t compromise on capabilities that support your goals.

• Email deliverability: Ensure your emails land in inboxes instead of spam folders. Choose software that can boost your deliverability rate and protect your sender reputation with features that improve targeting, ensure clean contact lists and offer spam detection.

• Scalability: Mass email software costs often rise as your list grows. Choose a service with pricing that stays predictable and reasonable as you send more emails and add contacts. Make sure higher volumes don’t quickly push you into expensive plans.

• Integrations: Email works best when it connects to your existing tech stack, including CRM, analytics, e-commerce and other platforms. Integrations reduce manual work and switching between tools and help you send more relevant, timely campaigns.

• Customer support: When something goes wrong, fast support matters. Look for responsive customer service, clear documentation and onboarding help if you’re new to mass emailing.

Prioritizing these basics will help you choose a tool that supports both your current campaigns and long-term growth.

Mass email best practices

Mass email campaigns once involved sending identical emails to your entire subscriber list.

As spam filters evolved, that approach stopped working and began to harm deliverability. Marketers now know that personalization, automation and tracking make mass emails far more effective.

Using the following best practices, you can learn how to send mass emails to the right people at the right time and make sure that you’re hitting their inbox.

Know the CAN-SPAM Act

The CAN-SPAM Act defines what you’re allowed to send in marketing emails and who you’re allowed to send them to and all mass emails must comply with the act.

Under the CAN-SPAM Act, you’re not allowed to send misleading, deceptive or false information. You also have to identify promotional emails as an advertisement and allow recipients a way to unsubscribe from specific lists (or opt out completely) should they wish to.

For every email that violates CAN-SPAM, you could face fines up to $53,088. Knowing it thoroughly is essential for any marketing team.

For more information, see the FTC’s page on the Act.

Have an eye-catching design

Strategically designing your email to resonate with your target audience is a great way to increase the chances of your email getting read and the links it contains being clicked.

When it comes to great email design, there are two key factors:

1. Clear, easy-to-read format. Keep your email simple. Use a basic, clean font and a font size that’s easily readable on all devices. If your email is too dense, cluttered or confusing, people simply won’t read it.

2. Aesthetically pleasing design. Think about unique imagery and color schemes. Make sure your content is true to your brand and consistent with your style guide. One way to achieve this is by using trusted email templates.

Good email design reduces cognitive load, helping readers quickly understand your message and take the desired action.

Make sure your ESP can handle the volume

Most email service providers (ESPs) will have a solution for sending out mass emails, but some experience bottlenecking and lags, which can lead to inaccurate sending times, especially for large lists.

Ensuring your ESP can handle your mass emails is the first step to them reaching your recipients’ mailboxes when you want them to.

Provide value

If your mass emails don’t provide value to your customers, subscribers and prospects, there’s no reason for your recipients to opt in or read the email.

To ensure that you’re providing value, focus on your target audience. Asking yourself, “What are my customers’ needs and how can I meet them?” will help you to create a targeted marketing strategy that addresses what your customers want, providing value from the get-go.

For instance, you may want to provide educational content that teaches your customers more about the industry issues that your product can help solve. In this case, you can send out guides, FAQs or step-by-step videos.

Use personalization

When you tailor your email toward each recipient, it feels more personal, thoughtful and human, which ultimately improves its performance.

Research from Belkins shows that emails with personalized subject lines boost open rates by 31% and more than double reply rates.

Luckily, there are plenty of tools on the market that automate the process of personalization, taking most of the work out of it.

To create personalized email sequences:

• Include the recipient’s name in the subject line or salutation

• Send standout emails for customer anniversaries, birthdays or special occasions

• Send emails based on their actions, like a how-to guide for a product they bought

• Reach out at the best time based on their timezone

Personalization can turn mass emails into conversations your readers care about, which naturally leads to higher engagement.

Include a call-to-action

The CTA, or call to action, is a written directive that persuades an email recipient to do something, giving your mass email a purpose and guiding readers toward the next step.

For example, you might include a button that says “Find out more”. The goal is to get the recipient to click that button, go to your website and learn more about how your product can help them (and ultimately book a demo or make a purchase).

Consider the following factors when creating your CTAs:

• Placement. Your CTA should follow the main text or images. It shouldn’t be so far down that the recipient has to scroll endlessly to find it, but it also shouldn’t come before they know what they’re clicking through to see.

• Copy. The CTA should speak to the recipient’s needs or wishesKeep it short and sweet and have a clear idea of what you want people to do when they open your email.

• Design. Both image-based and text-based CTAs have their place depending on your email content. In either case, ensure the message stands out from the rest of the text. For example, make sure the color of the CTA button stands out while being easy to read.

Getting all three factors right is what turns a CTA into something readers can act on.

Optimize your email for all devices

With many people now accessing their emails via their phones, your email must be optimized for their smaller screens.

Pay attention to the subject line length, your pre-header text and the size of any images that you use.

It’s always a good idea to test your email before sending it out to ensure that your email is readable (and clickable) on mobile devices.

What not to do when sending mass emails

What you don’t do matters just as much as what you do when it comes to inbox placement and subscriber trust.

Making common mistakes will land your mass emails in the spam folder and annoy your subscribers. Here’s a list of what not to do when sending bulk emails.

• Don’t send mass emails from new domains. Email domains have sender reputations designated and monitored by internet service providers (ISPs). Sending an email blast from a brand-new domain increases your odds of going to the spam folder and can hurt your chances of future deliverability. Instead, warm up your domain by slowly ramping up your emails to trusted addresses first.

• Don’t send mass emails to old email lists. Old email lists are likely to be full of dead accounts and recipients who haven’t opted in to receive your emails. These issues mean you could be breaking the law (as outlined by GDPR in Europe) by accidentally spamming people. Make sure you clean up your email lists before sending a mass email.

• Don’t send mass emails to unverified email lists. Even if you use the best bulk email sender, if you use an unvalidated email list, you’re going to have a high hard bounce rate. Use an email validation service to ensure you’re only sending to real, active email accounts.

• Don’t mislead your recipients. Misleading your customers is illegal in many places worldwide. Violating these rules will quickly lead to hefty fines, losing your sender reputation and losing customers.

• Don’t use clickbait. Avoid titles designed to get recipients to open an email without delivering on the promise. Clickbait is more likely to be caught by spam filters. It’s also more likely to annoy your customers, driving them away and giving them a poor perception of your brand.

Skip the mistakes above to improve deliverability, build trust, stay compliant and keep your mass email marketing strategy healthy in the long term.
