Acumbamail
Free plan: Acumbamail vs Mailrelay
Acumbamail is a Spanish email marketing and SMS tool, founded in Ciudad Real in 2013 and owned by the Italian group TeamSystem since 2023.
It is a well-known option among SMBs, online stores and agencies in the Spanish-speaking market. It stands out for combining email and SMS on the same platform and for its support in Spanish.
But its free plan is small. Let’s look at what it offers, how it charges in 2026 and when another option suits you better, such as Mailrelay, which lets you send 80,000 emails a month without paying.
What is Acumbamail and what is it used for?
It is cloud-based software for creating, sending and measuring email campaigns. You can use it to design a newsletter, send it to your subscriber list and see who opens it and where they click.
It also lets you send SMS, create landing pages and forms, and connect your website or store to send transactional emails, such as order confirmations.
Its value proposition boils down to three ideas: simplicity, prices in euros and support in Spanish.
Who is behind Acumbamail?
The company was founded in Ciudad Real by several engineers who studied at the University of Castilla-La Mancha, including Ignacio Arriaga and Rafael Cabanillas. Its legal entity is Acumbamail S.L.
In 2018 it was bought by Growens, the Italian group that owns MailUp. And in February 2023 it passed into the hands of TeamSystem, another Italian business software company, along with MailUp and Contactlab.
According to Forbes, at that time it had more than 5,000 paying customers in Spain and Latin America and around 140,000 free users.
Today it still operates under its own brand, with its office in Ciudad Real.
What features does Acumbamail have?
The platform brings together everything you need to do email marketing without coding. These are its main features, according to its website and help center:
- Drag-and-drop editor with more than 850 templates.
- Automations with emails, SMS, delays, conditions and webhooks, from the Basic plan.
- A/B tests, full reports and contact segmentation.
- SMS in campaigns and automations, with prepaid packs or a monthly plan.
- Landing pages and forms, with a custom domain and white label on the PRO plan.
- Transactional SMTP to connect your store or app.
The PRO plan adds features designed for agencies and larger teams: agency accounts, automatic resending to those who didn’t open the campaign, list cleaning, Facebook Ads audiences and surveys.
How do Acumbamail automations work?
An automation is a flow of messages that is sent automatically when a condition is met.
The most common example is the welcome email each person receives when they subscribe.
In Acumbamail, every flow starts with a trigger. It can be a new subscriber to a list, a new subscriber to a segment or a specific date.
From there, you add steps. You can send an email or an SMS, wait a few days, split the flow based on what each contact does or notify another application with a webhook.
Automations are not included in the free plan. They come with the Basic plan, and PRO expands their options.
How much does Acumbamail cost in 2026?
Acumbamail has a free plan and three paid ones: Basic, PRO and Enterprise. What sets it apart is that it lets you choose how to pay.
| Payment option | How it works | Who it suits |
|---|---|---|
| By emails sent | Monthly plan based on the emails you send, from 20,000 a month | Large lists that send in moderation |
| By subscribers | Monthly plan based on contacts, from 2,500 | Small lists that send frequently |
| Prepaid credits | Email packs with no subscription fee, valid for 2 years | Those who send occasionally |
| SMS | Prepaid packs or a monthly plan with a 4-month minimum commitment | Those who combine email and SMS |
It doesn’t publish a fixed price table. The price comes from a slider on its website and changes with volume, which is why comparison sites give different figures.
If you pay annually, you save 20%.
Prepaid credits cost more per email than the monthly plan, and if you use up your plan, extra emails are charged separately.
For comparison, at Mailrelay the Standard plan costs €48 a month for 100,000 emails and 20,000 contacts. You can see all the tiers on the pricing page.
Is Acumbamail free?
Yes, it has a permanent free plan. It allows 2,000 emails a month to a maximum of 250 subscribers, with no commitment and no card required.
It’s enough to learn how to use the tool or for a very small list. But it has three clear limits.
Your emails carry the Acumbamail logo. The plan doesn’t include automations, A/B tests or SMTP. And phone support starts with the Basic plan.
With 250 contacts, as soon as your list grows a little, you have to pay. With Mailrelay, on the other hand, you can send up to 80,000 emails a month to 20,000 contacts without paying, without logos and with automations included.
Are 250 subscribers not enough for you?
With Mailrelay, you can send up to 80,000 emails a month to 20,000 contacts for free, with automations included and no logos in your emails.
Acumbamail support: how do they help you?
Support is one of its strong points, and the reviews reflect it. It provides support in Spanish by email, chat and phone.
However, phone support is only included from the Basic plan up. The PRO plan adds a monthly email marketing consultation, and Enterprise adds priority support and an account manager.
It also has a help center with guides and videos to answer the most common questions.
Acumbamail and the GDPR
Acumbamail is a Spanish company and, according to ComparaSoft, hosts its data on servers in Spain. It’s an argument it uses against US tools such as Mailchimp.
Even so, complying with the GDPR also depends on you. You need your contacts’ consent, ideally with double opt-in, and a visible unsubscribe link in every email.
Acumbamail pros and cons
It’s a solid tool for companies that sell in Spain and Latin America. But it’s worth knowing its limits before choosing it.
| Advantages | Disadvantages |
|---|---|
| Email and SMS on the same platform | Free plan of only 250 subscribers and 2,000 emails |
| Support in Spanish, with phone support from the Basic plan | Brand logo in emails on the free plan |
| Several ways to pay: by emails sent, by subscribers or prepaid | Not very transparent pricing, calculated with a slider |
| White label and agency accounts on the PRO plan | Fewer integrations than international tools |
| Spanish company with data in Spain | List cleaning and dedicated IP only on higher plans |
Acumbamail: user reviews
On Capterra it has a rating of 4.6 out of 5, from 155 reviews. Users particularly appreciate its value for money, ease of use and fast support.
Many compare it with Mailchimp and point out that it works out cheaper for them.
The most frequent complaint has to do with billing: several users report problems when downgrading their plan.
Its own help center makes clear that, when you change plans, any emails you haven’t used are lost.
ComparaSoft gives it a 7.5 out of 10. It scores high on support and price, and lower on integrations.
How is Acumbamail different from Mailrelay?
Both are Spanish, both charge mainly by emails sent and both offer SMS. The difference lies in what you get without paying and what each plan includes.
| Acumbamail | Mailrelay | |
|---|---|---|
| Contacts on the free plan | 250 | 20.000 |
| Free emails per month | 2.000 | 80.000 |
| Provider’s logo in your emails | Yes, on the free plan | No, not on any plan |
| Automations | From the Basic plan | Included in the free account |
| Phone support | From the Basic plan | On all plans, including the free one |
| List cleaning | From the PRO plan | On all plans |
Imagine you have 3,000 contacts and send a newsletter once a week: around 12,000 emails a month.
With Acumbamail, the free plan won’t work for you, so you need a paid plan. With Mailrelay, you can do it with the free account, with automations and phone support included.
