Top 7 Mass Email Services for High-ROI Email Marketing Campaigns in 2025

Handling mass email campaigns can get complex because, unlike regular B2B emails, they deal with a much larger number of users, personalization, and automated triggers.

Also, aspects like spam scores and even your emails being blocked by specific domains are always a possibility! 

But if you are a D2C brand that is an E-Commerce Store or even a SaaS company, mass email services drive conversions. So to help you out, here are the top services to look at…

What is a Mass Email Service?

Mass email services or bulk email marketing is email marketing done on a much larger scale than traditional B2B business and is more regularly done for D2C brands to help sell directly to consumers, where a huge number of touch points may be needed to convert.

That said, getting emails to inboxes and not being marked as spam has become more difficult with the February 2024 spam update. This is why choosing the right mass email service is all the more important.

Features to Look for in Mass Email Services

• Customization: Being able to customize your email to your brand guidelines easily using drag-and-drop features, as well as unique templates that fit your branding needs or even conversion goals, is essential.
• Analytical Tools: In mass email segmentation, analytical data based on who is responding to your mail is the foundation of everything. To have email campaigns that constantly improve, having access to email and customer insights is non-negotiable.
• Dedicated IPs: With many email services, when you send mass emails from specific domains, they often come from the same IP address. If an email service has blocked that IP address as a spam IP, it will affect your deliverability and how well you can manage your spam score.
• User Email Segmentation and Personalization: If you segment users based on purchase history, location, or even the amount purchased, you can create much better campaigns that are more successful. For this, a mass email service that has easy segmentation and micro-segments users based on this can be invaluable.
• Automation Triggers: Email is not a one-time thing; it needs a lot of personalization based on actions. With automation triggers, you can decide what type of email and message to send to users with specific, hyper-personalized, and relevant messaging to convert better and retain brand loyalty.
• Support for AMP: This allows for dynamic, interactive content directly within emails, enhancing user engagement
• Low spam scores: This is a major part of what affects the deliverability of an email! 

A lot of this depends on the domain and whether these mails are from dedicated IP addresses specific to you. Without a good spam score, your emails will not be delivered, and you’ll even have trouble getting clicks that are at 0.5% of your email list.

G2 Score for OmniSend: 4.6/5

5. ClickFunnels

For individuals looking to have very small email marketing campaigns and are in the starting stage of the business, ClickFunnels is a good option as it is easy to use.

That said, it is not a reliable option for scaling up past a certain point. Also, users have stated that their customer service is not as reliable as some of the others on this list.

6. Hubspot

Easily one of the best CRM software for tracking and following up with users, Hubspot as a mass email service and marketing tool is another popular option. 

If budget is not a constraint, Hubspot is definitely a top mass email service worth consideration. However,  if you are looking to be a little conservative with your spending, we’d recommend looking at Brevo or ZEPIC as they come with the same features but with a lot less investment.

G2 Score for HubSpot: 4.4/5

7. MailChimp

Mailchimp has long been one of the top solutions for mass email marketing. However, in recent times, many email marketers have noticed consistent price increases and a lack of transparency regarding billing—specifically, being charged for all contacts, regardless of whether they are active subscribers or not.

While Mailchimp remains a powerful tool, we recommend considering alternatives that are more affordable and scalable, especially for companies just starting out or those looking to allocate budgets to other marketing channels as well.

G2 Score for MailChimp: 4.4/5

How to Choose the Right Bulk Email Service

• Email Deliverability: Email deliverability is one other aspect that is a huge part of bulk email marketing. Is your email even hitting the inbox? Or is it automatically being sent to spam? Choosing an email service that has a reputation for good deliverability can play a major role in your email marketing success.
• Pre-built Email Templates: Pre-built email templates make your job a lot easier by limiting the amount of time you need to spend on creating your email flow and letting you focus more on ULM triggers.
• Customization: With email templates, customization is also a huge aspect of selection. This is in terms of email personalization that is in line with your brand guidelines and colors. On the other hand, services that also allow hyper-personalized emails that use attributes are definitely worth looking into when selecting your email marketing service.
• Granular Email Throttling and Limiting Control: Email spam scores are low, and to maintain deliverability, granular email throttling and limiting control is one functionality that email marketers need to watch out for. 
• Reliable Customer Support: With email marketing, where there are usually a lot of API integrations, having a reliable customer service representative to walk it through can help save you time and make sure your campaign stays on track
• Transparent Billing and Overage Charges: A lot of high-profile email marketing services exploit users based on overage charges and not paying close attention to billing. Choose an email marketing service where the pricing is transparent and affordable for your business to scale.

Mass Email Services and Bulk Email Senders Compared

The Top Mass Email Service for B2C Email Marketing

We would put ZEPIC as a top email mass service due to its omnichannel approach and how easy it is to execute and track campaigns across ALL channels.

More than that, it also comes with AI tool Zenie that lets you create automation flows in almost 1/10th the time other tools require. The tool itself also helps with not overwhelming users with content that’s irrelevant to them with the help of micro-segmentation.

After this, we would also mention Brevo for how reliable yet affordable it is; however, it is better suited for more medium or small-sized companies.

The Most Suitable Mass Email Service for B2B Email Marketing

In terms of B2B mass email marketing, Hubspot is a reliable choice, both suitable for smaller and larger enterprises.

However, for some companies new to the world of email marketing, MailChimp is also a good option considering you only use limited emails. But the caveat here is that as it scales and it can become significantly more expensive.

In terms of customization and personalization for better engagement, ZEPIC would be a solid choice to customize any complex B2B customer journeys.

Picking the Most Suitable Bulk Email Service for Your Businesses

An omnichannel marketing solution in 2025 makes a lot more sense than just a mass email service. This goes especially as email is unpredictable in some ways and can be influenced heavily by spam updates from different email hosting websites.

For organizations and eCommerce businesses, omnichannel marketing with a platform that enables this is what will help you stand out and have consistent revenue in the long run.

In terms of omnichannel marketing and mass email services, ZEPIC stands out as an easy-to-use tool. Want to see just what it can do? Let us know by reaching out for a free trial.
