Free Email Marketing Services for High-Volume Sending

You can send email campaigns to thousands of subscribers without paying from day one.

Many email marketing tools offer free plans so you can start sending bulk emails with no initial cost.

However, not all of these services truly allow you to handle large volumes of emails for free.

The differences between the capabilities of their free plans can be enormous.

That’s why it’s important to know which services allow you to send large volumes of emails with no initial cost.

And it’s also advisable to understand what their limits are.

Here, we’ll analyze email marketing platforms with free plans, comparing how many contacts and emails they allow you to send for free.

We will see that some free plans are quite restricted, while others leave more room to grow.

Lastly, we will highlight how Mailrelay excels with the most generous free account on the market.

This may seem biased to you, however it is something you can check and compare without any problem.

Email marketing services with free bulk sending

We present the main services that allow you to send bulk emails for free (no initial cost).

Below, we will detail the conditions of their free plans:

· Mailchimp – 500 contacts and ~1.000 emails/month for free

Mailchimp’s free plan allows you to manage up to 500 contacts and send about 1,000 emails per month in total.

This plan also has a daily sending limit of 500 emails.

This cap can slow down your campaigns as soon as your list grows a little.

It is a popular option to start in email marketing.

However, its limited capacity is a major drawback for any project looking to grow its subscriber base.

Another factor to consider is that the free version displays Mailchimp’s branding on the sent emails.

It adds a small banner with its logo in each email.

The platform also doesn’t provide continuous technical support.

As a free user, you only have some self-help resources.

In practice, after the initial phase you will be on your own if a problem arises.

· Brevo (Sendinblue) – unlimited contacts but 300 emails/day

Brevo (formerly Sendinblue) offers unlimited contacts in its database even on the free plan.

But it limits sending to 300 emails per day (about 9,000 per month in total).

This daily restriction prevents you from sending an email to your entire list at once.

This happens if your list exceeds 300 subscribers.

For high-volume sending, the daily cap of 300 emails simply falls short.

On the free plan, Brevo adds its logo to the footer of your newsletters.

Your emails will include a note indicating that you use their platform.

To remove that branding and send without advertising, you will have to sign up for a paid plan.

Customer support is also very limited on the free tier.

Basically you will have to resort to documentation and other self-help resources.

· Acumbamail – 250 subscribers and 2,000 emails/month for free

Acumbamail offers a forever free plan with up to 250 subscribers and a maximum of 2,000 emails per month.

Additionally, it imposes a limit of 250 daily sends within those parameters.

In practice, it is designed only for very small lists and for testing the basics of the tool.

With 2,000 monthly emails, the quota can be exhausted quickly even with a modest contact base.

With the free account, all the emails you send include an Acumbamail notice.

It is a text or link that indicates the email was sent through its platform.

This advertising addition can detract from the professionalism of your newsletters.

To remove that branding and increase the sending limit, you will have to switch to a paid plan.

On the other hand, Acumbamail reserves personalized support for its paid customers.

As a free user, you basically have tutorials and FAQs as your main help.

· Teenvio – 5,000 contacts and 5,000 emails/month for free

Teenvio allows you to handle higher volumes for free than many other tools.

Its no-cost plan supports up to 5,000 contacts and 5,000 emails per month.

In pure numbers, it is more generous than most competitors.

Additionally, it includes technical support even on the free plan, an important plus if you value having direct help.

However, 5,000 monthly emails are still a limit to consider if your base grows.

You will also fall short if you need to send campaigns more frequently.

For example, with 5,000 subscribers you could only send them one bulk email per month within this free plan.

In summary, Teenvio offers a good margin to start.

However, it may fall short if you need to send more emails.

It also becomes insufficient if you plan to expand your list beyond 5,000 contacts.

· FromDoppler – 500 contacts, unlimited emails (90-day trial)

Doppler takes a different approach: it offers a temporary free plan as a trial.

It allows up to 500 subscribers and unlimited emails to those contacts, but only for the first 90 days.

In practice, it is like an extended trial to evaluate the platform with real use.

After those initial 3 months, you would have to sign up for a paid plan to continue sending emails.

In summary, FromDoppler does not offer a permanent free solution.

It can be useful if you only want to test all its features in the short term.

During those 90 days you will have no sending restrictions (beyond the 500-contact limit).

However, it is not a viable option in the long term.

This affects projects looking to send large volumes of emails at no cost on a continuous basis.

As you can see, most tools significantly limit the capacity of their free plans

Even other popular options have significant restrictions.

For example, MailerLite allows about 12,000 emails/month with ~1,000 subscribers in its free version.

It’s more than some of the mentioned alternatives, but it still falls far short of Mailrelay’s figures.

Furthermore, in many cases advanced features are out of reach in the free modality. We are talking about complex automations, deep segmentation, or detailed reports.

So, is there any platform that truly allows you to send large volumes of emails with no initial cost, with fewer limitations?

Yes, there is. Mailrelay offers the most extensive free plan on the market in terms of sending volume.

Additionally, it includes premium functionalities from the very first moment.

Mailrelay: The Highest Free Sending Volume and Much More

Among the services analyzed, Mailrelay stands out as the best option for sending large volumes of emails without paying anything upfront.

The free plan is exceptionally generous and far surpasses the alternatives.

But it’s not just about the volume.

Mailrelay also provides advanced functionalities and quality support at no cost. These are aspects that most competitors don’t offer in their free accounts.

· Extremely generous free plan (up to 80,000 emails/month)

Mailrelay offers the most generous free account in the sector.

It allows you to manage up to 20,000 contacts and send up to 80,000 emails per month at no cost.

These figures surpass those of any other mentioned provider.

This means you can reach a large audience at no cost.

This generous free plan is ideal for entrepreneurs, bloggers, or growing SMEs.

It allows them to send newsletters on a large scale at no cost.

Even large companies can use this free account to test the platform’s high-volume capabilities.

Mailrelay allows you to test bulk email without commitment and without worrying about hitting sending limits.

Furthermore, this free plan has no expiration date or fine print.

Other platforms offer only temporary trials or reduce the free tier over time. Mailrelay, on the other hand, maintains its free plan forever, without expiration as long as you use it actively.

You won’t have to worry about it expiring in a few months.

In summary, you will be able to send bulk emails for free on a sustained basis.

There will be no immediate pressure to switch to a paid plan.

· Dedicated technical support even on the free plan

Mailrelay provides another differential benefit: it offers customer support even to free users.

Support is offered by phone, online chat, and a ticket system.

An expert team handles all inquiries.

If you have technical questions or need help with the configuration, you will not be alone.

The Mailrelay team guides you personally in your language.

This level of support is uncommon in free plans.

Many competitors drastically restrict customer service, or don’t even offer it, to those who don’t pay.

In contrast, Mailrelay does help even the users of the free version.

Thus, you will be able to solve problems and make the most of the tool from the beginning.

Knowing that you have human support from day one gives you peace of mind to launch your campaigns.

You won’t have to deal with only documentation or forums if any inconvenience arises.

· Automations and A/B tests without restrictions

The Mailrelay platform includes advanced automation features even on the free plan.

This is something you would normally find only on paid plans.

You can create complete automation flows, for example autoresponders or welcome sequences.

It is possible to configure conditions, segmentations, and waiting times according to your needs.

Contact segmentation by tags or custom fields is also available.

This allows you to send personalized messages to different groups within your list.

Mailrelay also allows you to run A/B tests on your campaigns with the free account.

You can test different versions of a subject or content on a small part of your list.

After that, the platform automatically sends the winning version to the rest of the subscribers, thus optimizing the results.

Having advanced automations and A/B tests from the beginning helps you build a more effective email marketing strategy. And all without having to pay for a higher plan.

The best part is that all these features are easy to use.

Mailrelay offers an intuitive automation interface, suitable even for those with no experience.

The automation editor works by simply adding actions to build your flows.

You can define simple triggers (for example: when a user subscribes, send a welcome email).

It is also possible to establish conditions without complications.

In short, Mailrelay’s automation is powerful but easy to use.

It is ideal for companies that want to save time with automatic emails but don’t need overly complex solutions.

· Real-time reports with heat maps

To optimize your campaigns, Mailrelay provides real-time statistics included in the free plan.

You will be able to consult all the key data of your bulk sends.

For example, you will know who opens your emails and who clicks on the links.

You can also track unsubscribes and identify which email addresses bounce.

The platform even generates click maps or heatmaps on your newsletters.

It visually highlights which links subscribers interact with the most.

With these free, detailed reports, you can measure the impact of your emails and improve your strategy.

For example, you can identify which subject lines get higher open rates.

You will also be able to see which calls to action generate more clicks. Even for free accounts, Mailrelay gives you the necessary analytical tools.

With this data you will be able to optimize the ROI of your email marketing campaigns.

Many other platforms limit the statistics in their free accounts.

Mailrelay, on the other hand, offers you a complete picture of results from the very first moment.

· Easy integrations and large-scale list management

Mailrelay is designed to integrate seamlessly into your marketing ecosystem.

The platform has an official WordPress plugin.

This plugin makes it easy to connect your account with your website or online store.

For example, you can capture subscribers directly from a form on your page.

You will also find a robust REST API so that developers can integrate Mailrelay with other systems or custom CRMs.

This way, even if you are starting with the free version, you can integrate Mailrelay into your workflows.

All without complications.

On the other hand, the platform simplifies contact importing and the administration of large lists.

You can easily upload your subscriber databases through CSV files or other sources.

This works even if it involves tens of thousands of contacts.

The Mailrelay system automatically detects duplicate entries to avoid repeated emails.

It also manages unsubscribes, bounces, and inactive subscriptions to keep your list clean.

In other words, it offers the necessary facilities to handle large volumes of subscribers efficiently.

This is essential when it comes to sending bulk emails.

· Intuitive interface and newsletter editor with AI

When it comes to creating your emails, Mailrelay provides a very complete and easy-to-use newsletter editor.

The interface was designed with simplicity in mind.

Everything is accessible in a few clicks and with clear menus.

Even if it’s your first time using email marketing, you won’t feel overwhelmed by the tool.

The email editor includes customizable templates and “drag and drop” options.

You can add images, text, and buttons without touching a single line of code.

In addition, it integrates Artificial Intelligence capabilities to help you write content.

If you don’t have much time or experience to write attractive texts, don’t worry.

The AI-assisted writing feature can generate drafts of your newsletters or suggest phrases, saving you work.

This incorporation of AI is a very uncommon added value in the free plans of other services.

In short, the Mailrelay dashboard is simple but powerful.

The platform combines very high usability with innovative tools like the smart editor.

Thanks to this, creating and sending campaigns is an agile process.

You don’t need to be an expert to achieve professional newsletters with this tool, even using only the free version.

· High deliverability and sending reliability

Lastly, Mailrelay has earned a solid reputation for its high email deliverability.

It’s of little use to send tens of thousands of emails if they end up in the spam folder.

That’s why the platform takes special care of this aspect.

Mailrelay operates with optimized infrastructures. It has its own IP ranges and advanced systems (powered by AI) to maximize deliverability.

Additionally, it allows you to easily configure security authentications like SPF and DKIM.

This improves the trust of the email providers that receive your messages.

Thanks to these measures, even the free account helps your emails reach the inbox.

You can expect a high inbox delivery rate.

The reliability of the service is key when you handle large volumes.

Conclusion

As it could not be otherwise, we suggest you create your free account on Mailrelay.

Take advantage of its high free-sending volume to reach your marketing goals at no cost.

Create your free account and send up to 80,000 free emails per month, to a list of up to 20,000 contacts.
