6 Best Mass Email Senders for Bulk Email Blasts

A bulk email is the process of sending one email template to a large number of addresses at once. This can be a powerful marketing tool, allowing you to semi-personalise emails with marketing information, promotions, campaigns, or other news. But first, you need to decide which platform to use.

With so many email marketing platforms on the market these days, picking the right one for your needs can be tricky. For bulk email, quantity is obviously going to be a key consideration. You want to be able to send as many emails as you need - without restrictions - for the lowest possible price.

That’s not the only thing you need to consider, though.

What makes a good mass email sender?

Simply blasting emails at everyone you can doesn’t count as a marketing strategy - nor is it very legal, for that matter.

You also need to think about how you’re going to track those emails, check how users engage with them and automate your follow up email, depending on how people respond (if at all).

Constant Contact is the bulk email sender I’d start with if your list is growing faster than your sending volume. Its Starter Email plan costs $6/month, includes unlimited contacts and caps you at 2,500 email sends per month.

That trade makes sense for small businesses, solo entrepreneurs and seasonal projects. You can collect contacts without watching the bill climb every time the list grows, although one full-list campaign to 2,500 people uses the whole monthly allowance.

I tested Constant Contact across eight areas in August 2026, including its editor, AI, automation and deliverability. The default email scored 9/10 in Mail Tester and the editor was easy to use, but the automation builder is better suited to simple welcome sequences than behavioural campaigns.

If you send less than 2,500 emails a month, Constant Contact’s Starter Email plan is awkward to beat on price. If you blast a large list every week, the cap stops being clever and becomes the problem.

02ActiveCampaign

ActiveCampaign is arguably one of the best email marketing tools on the market. With over 150,000 small business customers, they came out #1 in our annual study of 100+ email platforms.

Sending bulk emails is one of the many things you can achieve with ActiveCampaign. This platform makes more sense for businesses that need an all-in-one CRM, email marketing and automation system.

You can send unlimited emails on every plan, with pricing based on the number of contacts and user accounts you need. More expensive plans also get you access to more advanced features like A/B testing, machine-learning and dedicated support.

For 500 contacts, pricing starts as low as $9/month for up to three users, with a $49/month version also listed. At 10,000 contacts, ActiveCampaign remains competitive, with prices ranging between $111/month and $399/mo.

At $199/mo, ActiveCampaign’s Plus package covers you for 10,000 contacts, unlimited emails and up to 25 user accounts — plus a lot more marketing and automation features than you’ll get from most platforms in this price bracket.

Some other options in this list give you more mass email power for the money, but ActiveCampaign makes sense if you want email marketing, automation and CRM in one place.

Among the providers we’ve looked at, ActiveCampaign is strongest on automation, sales tracking, reporting and integrations. The trade-off is that you’re paying for a fuller marketing stack, rather than the cheapest way to blast a list.

03Brevo

Brevo is a truly sophisticated piece of email marketing software offering one of the best email builders on the market. Aside from editing templates, you can create your own design from scratch, using its drag-and-drop builder.

Brevo’s pricing is unique, too. Instead of charging you based on the number of contacts you’re sending to, Brevo sets its prices based on the number of emails you’re sending.

So you can send up to 300 emails every day for free, Brevo Lite starts at 10,000 emails per month for £16.5/monthup to 100,000 emails per month for £59.5/mo. Brevo Premium starts at 20,000 emails per month for £41.5/monthup to 1,000,000 emails per month for £424.15/mo. All plans come with unlimited contact storage

Once again, custom pricing plans are available if you need to send higher volumes.

Those prices are incredibly competitive and you’re getting a lot of additional email marketing features in terms of automation, contact segmentation and reporting. Brevo also has some of the best transactional email features we’ve come across, which we’re still using today here at Venture Harbour.

Brevo isn’t only there to help you send emails, either; it’s packed full of features to help you generate more leads and increase your email marketing list. Its form builder aims to turn your website into a stronger lead gen tool and improve the results of your inbound marketing efforts.

This is also the first platform we’ve looked at that offers serious reporting tools - crucial for gauging the performance of your emails after they’re sent out and optimising campaigns for better results.

Brevo still has its limitations, though.

While it offers some great automation and lead generation features, it doesn’t match the industry leaders on this front. For example, there’s no customer relationship management (CMS) platform included and its lead tracking capabilities aren’t as advanced as some of its competitors (most of which are more expensive, though).

04Moosend

Moosend is a beginner-friendly bulk email sender.

While not nearly as powerful as ActiveCampaign on features, what I do like about Moosend is that you can access all of their features from as little as $10/month. ActiveCampaign, on the other hand, separates their more advanced features onto higher-priced plans.

Moosend also offers unlimited email sending regardless of which plan you’re on.

Their platform is easy to use, albeit has a slightly dated feeling to it. Your email recipients will never see this platform, so it’s debatable how much of an issue this is.

A major benefit with Moosend (right now) is that they offer each customer agency-level support, to help you with anything from strategy to delivery optimisation.

They’ve advised me that this may not always be the case, but for the time being it’s a major perk that other bulk email tools charge a hefty fee for.

05Kit

Kit is the bulk email sender for individuals in creative industries, such as authors, teachers, and bloggers.

With Kit, do not expect any fancy features. There is no predictive sending, split test A/B testing, and the reporting is bare-bones. For those who just need an easy-to-use tool to send emails to a large list, it’s perfect.

Kit’s email editor is a simple drag-and-drop editor, with few bells and whistles. One major difference compared to ActiveCampaign and Moosend, is that Kit does not offer email templates — as they encourage users to send plain text emails.

Similar to both of the tools above, Kit’s pricing allows for unlimited email sends, but the price is based on the number of contacts on your list. Their pricing is reasonable — though not too dissimilar to ActiveCampaign’s, which we felt generally offers more bang for its buck.

06MailerLite

MailerLite is hands-down the most affordable bulk email sender for smaller list sizes. If you have less than 1,000 contacts, MailerLite is free to send up to 12,000 emails a month.

Starting at $15 for 2,500 contacts, it’s one of the most affordable email marketing tools out of over 100 email marketing tools that we analysed. More importantly, their software is also very easy to use and has a good set of features.

While nowhere near as powerful as ActiveCampaign from a feature standpoint, MailerLite does have all of the basic features you’d expect of a bulk email sender - from personalisation tags to sending by time-zone, and A/B testing.

Ultimately, if you’re a business looking for an all-in-one email marketing solution, I would still err towards ActiveCampaign. But if it’s a personal or side project you’re looking to send bulk emails for, where affordability trumps potential for growth, MailerLite is a brilliant option to consider.

Which is the best bulk email sender?

Each bulk email sender here has strengths in its own right. Constant Contact keeps a lightly used list cheap, while ActiveCampaign gives you a complete all-in-one sales and marketing platform.

The gist: price depends less on list size than on how often you email it.

Tool	Monthly price for 2,500 contacts	Monthly price for 10,000 contacts	Monthly price for 100,000 contacts
Constant Contact Starter Email	$6	$6	$6
MailerLite	$15	$50	$360
ActiveCampaign	$39	$111	$299
Moosend	$20	$125	$585
Brevo	$39	$66	$173
Kit	$49	$119	$679

Constant Contact’s $6 row is Starter Email pricing, which only includes 2,500 total sends per month. If you need to email the whole list regularly, compare its Core plans instead.

Brevo stands out on price once the list gets bigger: $66 at 10,000 contacts and $173 at 100,000. It’s less compelling at 2,500 contacts, where MailerLite and Constant Contact are cheaper.

Its focus on deliverability and transactional email is the reason I’d look at it when inbox placement matters as much as price.

FAQ

What is the difference between bulk email and spam?

Bulk email is a legitimate marketing tool where you send one message to multiple recipients who have opted in. Spam is unsolicited email sent without consent. Permission is the key difference — bulk email senders like ActiveCampaign and Brevo require verified subscriber lists to stay compliant with GDPR and CAN-SPAM.

How much does bulk email software cost?

Bulk email software typically ranges from free plans for small lists to £20-100+ per month for enterprise solutions. It depends on subscriber count and features. Most platforms use a tiered pricing model based on contacts. MailerLite and Moosend offer affordable options for startups, whilst ActiveCampaign caters to larger organisations.

Can you send bulk emails for free?

Yes, several bulk email senders offer free plans with limits on contact numbers and monthly sends. Free tiers typically support 500-1,000 contacts and are useful for testing. You’ll need to upgrade as your list grows — MailerLite and Moosend provide generous free options before requiring payment.

What features should a mass email sender have?

A quality mass email sender should include automation, segmentation, personalisation, analytics, and deliverability tools. The point is to help campaigns reach inboxes and perform well. Automation and segmentation matter because they let you send targeted messages at scale rather than one-size-fits-all blasts. That tends to improve engagement rates.

Is bulk email marketing legal?

Bulk email marketing is legal when you follow regulations like GDPR (UK/EU), CAN-SPAM (US), and CASL (Canada). They require explicit consent, clear unsubscribe options, and honest sender identification. Compliance is mandatory — reputable bulk email platforms like Brevo and ActiveCampaign enforce these rules automatically to protect both senders and recipients.

Which bulk email sender has the best deliverability?

ActiveCampaign and Brevo consistently achieve the highest inbox placement rates due to their advanced authentication protocols and sender reputation management. Deliverability depends on your sender practices. Even the best platforms can’t guarantee inbox placement if you’re sending to inactive addresses or using poor list hygiene.

Can you personalise emails in bulk email software?

Yes, all modern bulk email senders allow dynamic personalisation using merge tags. You can insert subscriber names, purchase history, or custom fields into templates. Personalisation can boost open rates — platforms like MailerLite and Kit make it simple to add first names or segment-specific content without manual effort.

What’s the best bulk email sender for small businesses?

Constant Contact is the best fit if you are building a list but sending fewer than 2,500 emails a month. MailerLite and Moosend give you more room for regular sending, but their pricing rises as the list grows.
