Best certified mail: For business needs you would need to open a Certified Electronic Mailbox , as you are aware of the fact that the PEC allows you to send and receive emails having the same legal value as a registered letter with return receipt, thus avoiding very long lines in the mail for send a paper copy.

How do you say? That’s the way things are and, therefore, would you like to clarify which is the best certified mail for you? If so, know that you have come across just the right guide. In the course of this tutorial, in fact, I will provide you with more details on how certified mail works and I will talk to you in depth about the characteristics of the PEC mailboxes that you can subscribe to with various companies that offer this type of service.

Therefore, I invite you to take a few minutes of free time and sit comfortably, so as to carefully read the information I will provide you in the next chapters. You will see that, in the end, you will be able to easily identify the PEC service that best suits your needs. At this point, I just have to wish you a good read and wish you a big good luck for everything!


Preliminary information

Before seeing in detail which companies offer the purchase of a certified mailbox , it is necessary that I help you to understand some relevant issues about this service.

First of all, you must know that there is no better certified mail in absolute terms, as each of the companies I will talk about in my tutorial offers a valid PEC service with different characteristics and target audiences. Therefore, the choice depends on your needs.

That said, what I suggest you evaluate before purchasing a PEC mailbox is the relationship between storage space and price of the service and services included (e.g. access from mobile app, archive, etc.).

A clarification, then, must be made on the obligation to use this type of e-mail. Since 2013, the PEC has become a mandatory tool for all businesses, sole proprietorships and freelancers enrolled in an order or college . Consequently, if you fall into one of these cases, you will certainly need a certified mail.

For private citizens, the PEC is not mandatory. In reality, however, in my opinion, it can also prove to be very useful for private individuals: for example, you may need it if you have to send official communications or request information from public offices or if, in any case, you wish to communicate with another person (also with PEC) and give legal validity to your messages.

As for how it works, you will be interested to know that the PEC basically works like a traditional email address, allowing you to send and receive email messages. However, what distinguishes it from a traditional mailbox is its system for sending emails in a certified manner, but everything happens “behind the scenes”, without the user having to do anything in particular or use particular devices / software.

After sending a PEC email, in fact, the message is checked by the sender’s provider, sent to that of the recipient, validated again and finally delivered to the destination PEC box. Following these steps, notifications are sent certifying the sending and delivery of each message. The functioning of certified e-mail can therefore be compared to sending a registered letter with return receipt: the legal value is, in fact, the same.

To use a PEC, as already mentioned, it is not necessary to download particular management software. Many companies that provide PEC services offer the possibility of using it through a Webmail service , therefore from any Web browser. In some cases, this service is accessible and optimized to be used also from mobile, or usable through special apps for Android and iOS / iPadOS .

Alternatively, if you already use a client for managing e-mails (eg Microsoft Outlook or Apple Mail), you can configure the sending and receiving of e-mails in this, using the traditional IMAP protocol (or even the POP one , even if now dated and not recommended).

Finally, it is necessary to clarify a fundamental issue: certified e-mail is a service that can only be obtained by paying for a subscription . At the time of writing, in fact, there is no completely free certified e-mail service.

As I will explain to you in this guide, some companies offer the possibility of using a PEC for free, but only for a few months, as a trial version . Once this test has expired, the use of the PEC is subject to payment with monthly or annual billing.

Best free certified mail

Having made the necessary premises regarding the functioning of the PEC , we can begin to review what I believe are the best certified e-mail services, starting with the companies that offer the opportunity to try the service for free .


Create a PEC with Register

Among the companies that offer the subscription of monthly subscriptions, for the purchase of a certified e-mail box with the possibility of trying the service for free for a limited duration, there is Register , a well-known hosting and domain company.

The PEC service of the website is called Agile PEC and, among its most prominent features, there is a PEC mailbox with 2GB storage space with SMS notifications . The consultation takes place from a specific Webmail service with an optimized user interface even when browsing on mobile devices.

If you wish to purchase this certified e-mail service, you have the opportunity to try it for free for 6 months , being able to take advantage of all the features listed. After the trial period, the subscription cost is 33.90 euros per year + VAT. In case of non-renewal after the free trial, however, 9.90 euros will be charged as a setup cost.

Clearly this is a certified email service designed for private individuals; for companies, on the other hand, there is a dedicated plan which, called PEC Unica , allows you to have access to a certified 3 or 5 GB mailbox with all the characteristics of Agile PEC : the price starts from 43 per year + VAT.



Another company that offers the opportunity to try its PEC service for free is Legalmail , which has a subscription plan that can be activated free of charge for 6 months.

It is, in fact, the PEC Silver plan , which allows you to activate an 8 GB PEC mailbox whose characteristics are the security archives , access from mobile devices and notifications via SMS . At the end of the trial period, the cost of activation is € 39 plus VAT per year.

Alternatively, there are the PEC Bronze and PEC Gold plans which, however, cannot be activated as a free trial.

Best paid certified mail

Now let’s move on to what are the offers for the purchase of a paid PEC , through an overview of the services offered by the most famous companies in the sector.


PEC Aruba

Among the best PEC services we must also include the service offered by Aruba , a well-known Italian company that operates in the sectors of Web hosting, cloud and online practices.

The PEC Standard plan costs 5 euros + VAT / year the first year and then 7.90 euros + VAT / year and offers a 1GB PEC mailbox valid also for the digital home (mandatory from 1 October 2020 for companies and professionals, for receive communications from the PA) with receipts of successful / non-delivery, legal validity and non-repudiation of messages sent / received.

It supports messages with a maximum size of 100MB and with a maximum of 500 recipients in a single sending.

The PEC Pro plan costs 25 euros + VAT / year and adds 2GB of space, SMS notifications and the security archive with 3GB of space to the features of the Standard plan. Finally, the PEC Premium plan costs 40 euros + VAT / year and includes all the benefits of the Pro plan, but with 8GB of storage space. It is also possible to activate the PEC on domain (from € 7.90 + VAT / year).

Aruba’s PEC service is accessible from the latest generation Webmail , very easy to use and full of interesting features (including viewing electronic invoices ); from a mobile app for Android and iPhone / iPad (with practically the same functions as Webmail) and from third-party email clients (via the configuration of the IMAP protocol ). In any case, it guarantees high security standards, with multiple antivirus and antispam, constant vulnerability control, blocking of non-secure attachments, use of the secure TLS 1.2 protocol for communications and compliance with all the rules of the GDPR for the processing of personal data.


PEC mail

Among the best certified e-mail services it is right to include PosteCert offered by Poste Italiane.

For individuals it is possible to subscribe to the Basic PEC plan for individuals : at a cost of € 5.50 + VAT per year, a PEC mailbox with 100 MB space is activated , which allows you to send a maximum number of 200 emails per day.

Alternatively, there are the PEC Base Business plan and the PEC Base Business plan : both concern the activation of 5 PEC mailboxes with a duration of 1 to 3 years, 1 GB space and a maximum sending of 200 emails per day.

Business users interested in subscribing to a plan to obtain a PEC must contact the local commercial managers relating to the business market and the Public Administration, as the prices of the business PEC must be budgeted with a consultant.



Among the PEC services that I would like to recommend there is also the one offered by the KOLST company . The prices of the subscriptions are in line with those of other companies and there are several possibilities for activating a certified e-mail.

The basic plan is called Smart and, at a cost of € 5 + VAT per year (which becomes € 6 + VAT / year for subsequent renewals), it offers the possibility of obtaining a certified e-mail box with 1 GB of space. ‘storage.

This plan includes a PEC with 5GB storage on a customizable domain. It includes notifications of receipt and the ability to send emails in an unlimited manner.

The third KOLST offer is the Dominio 10 plan which costs € 30 per year + VAT (€ 40 + VAT per year for subsequent renewals). The subscription of this annual subscription offers a certified mailbox with 10GB storage space. Activation on a custom domain is also included; moreover, the notifications of receipt can also be activated via SMS.

Best certified mail app

Send PEC with Gmail from iOS

Have you purchased a PEC mailbox and, now, would you like to know which is the best app for certified mail , as you need to use it from smartphones and tablets?

In this case, you must know that there is no absolute best app for managing the PEC as, as explained, some managers offer the possibility of using it through a special dedicated app for Android and iOS / iPadOS.

If, however, the service you have activated does not have a default app for using the PEC , don’t worry: you can easily configure it in the main apps for managing e-mail on mobile devices, such as Gmail (for example ) ( Android / iOS / iPadOS ) and Mail ( iOS / iPadOS ).

In fact, if for example you want to configure the PEC in the Gmail app , you must first have the IMAP configuration parameters, which you can easily find by consulting the website of the PEC provider you have subscribed to.

Therefore, if you have the parameters in question, all you have to do to configure the PEC in the Gmail app is to press the Login> Other items located on the main screen of the app in question.

Then, type your PEC email address in the appropriate text field and click Next , in order to indicate the incoming and outgoing server settings , such as, for example, the password and data of the IMAP and SMTP server . Finally, click on the Next button to finish the configuration procedure.
