Antispam policy

Gumbamail offers a software service to their customers so they can send messages to their current and potential clients based on permissions. Therefore, sending unsolicited mail through our system is forbidden. Acumbamail considers an email message to be unsolicited if the recipient has not given clear and categorical permission to the sender to receive email messages from said sender. Thus, we forbid our clients from using bought, shared, commercialised or added lists. It is also forbidden to send mail with third-party content. All of our customers must comply with this policy. If Acumbamail discovers that a customer is sending unsolicited emails, we will stop providing our services to said customer.

As a means of avoiding Spam we have to check that the customer owns their domain. We also have two mechanisms to allow the user to unsubscribe quickly and easily, or when receiving the email using a visible link or marking the email as Spam (if the ISP returns us that information). The platform manages unsubscriptions automatically.

1. Current Legal System

1.1. Commercial messages and promotional offers will be governed by their current regulations on commercial materials and advertising, as well as by Law 34/2002.

1.2. In addition, Organic Law on Data Protection 15/1999 of 13 December, governing the Protection of Personal Information, will be applied, as well as its regulations regarding the collection of personal information, informing interested parties, and creating and maintaining personal data files.

Below is an analysis of the different articles of Law 34/2002 or LSSI:

2. Constraints on the piece or communication being sent

According to article 20 of Law 34/2002 or LSSI, any communication sent should include certain information and comply with the requirements outlined below:

2.1. Commercial messages sent electronically must be clearly identifiable as such and they must indicate the physical or legal person on behalf of whom they are made.

2.2. In the case of promotional offers, such as those that include discounts, prizes and gifts, and contests or promotional games, following the corresponding authorisation, it should be ensured that, aside from the requirements in the previous section and the regulations governing trade management being complied with, they are clearly identified as such and the conditions of access and, if applicable, participation, are expressed clearly and unequivocally.

3. When sending communications via email is forbidden

According to article 21 of Law 34/2002 or LSSI, it is forbidden to send promotional or advertising messages via email or any other equivalent medium of electronic communication that have not been previously requested or expressly authorised by the recipients of said messages.

In the event that the recipients have had a commercial relationship with the sender, sending messages via email is authorised, as long as the emails refer to products or services offered by the sender and that are similar to those which were initially the purpose of the contract.

Therefore you may send communications via email to your customers, both current and those which which you have had a commercial relationship in the past, as long as you respect the conditions regarding the messages or communication being sent and the rights of the recipients, as explained in section four of this document.

4. Rights of the recipients

According to article 22 of Law 34/2002 or LSSI, the rights of the recipients of commercial messages via email are as follows:

4.1. If the recipient of the services were to provide their email address during the contracting or subscription process for a service and the seller or service provider intends to use it to send commercial information at a later date, they must notify the customer of their intention to do so and request their consent to receive said communications before the contracting procedure is complete.

There are several procedures for doing this:

Double Opt-in: Registration system by which the user accepts and confirms their express consent expressly and unequivocally (generally through a validation done by email), though it can always be revoked, to receive messages via email.

Notified Opt-in: Registration system by which the user subscribes via the Opt-in system and immediately afterwards receives a message giving them the option to unsubscribe. If the user opens the message but does not unsubscribe but remains subscribed, it is a notified Opt-in.

Opt-in: (Authorisation) It is given when the user expressly and unequivocally gives their permission to a company to use their email address with the purpose of receiving commercial information, even if they do not confirm the subscription from their own email account (as is the case generally with the double Opt-in).

In addition, the Organic Law on Data Protection 15/1999 of 13 December establishes the requirement that when personal information is collected, such as email addresses, the existence of the file should be notified to the Spanish Data Protection Agency (

4.2. The recipient may remove their consent to receive commercial information at any time by simply notifying the sender of their wish to do so.

To this end, service providers must put simple and free procedures in place so that the recipients of the services can withdraw the consent they have given.

In addition, they must provide accessible information on electronic platforms regarding said procedures.

* Note: This text is for information purposes only, and in no case should this information be considered legal advice.

Warning about legal consequences

If you take part in any illegal activity by violating the laws which govern the sending and content of mass emails, or if you try to take advantage of any feature of the platform which violates our Terms of Use by taking actions such as using our servers to store images, or send emails created using Acumbamail but sent using a different service, or not paying a pending invoice, we have the right to charge a pre-established amount, calculated by estimating the real damages that your conduct would probably cause, including lawyer fees. We offer complex and powerful tools at a very low price. In exchange, we expect our customers to act with integrity, following our rules in order to help us maintain our reputation.
