How to send a certified email with Aruba: Now that you too have a certified mailbox purchased on, it’s time to use it to send important communications to colleagues, professionals or public administration bodies. The fact is that you have no idea how to do this and therefore, being afraid of making some mistakes, you would like a hand to understand how to proceed.

There is no need to worry, because I am here to help you. In fact, in this guide of mine, I will show you how to send a PEC with Aruba , in order to communicate with other PEC owners, both through the use of the service’s Webmail panel and through an e-mail client and app for smartphones and tablets.

Are you eager to get started, aren’t you? Very well: sit comfortably and carefully read all the tips I have prepared for you in this guide of mine. Are you ready? Let’s get started right away! All that remains for me is to wish you a good reading and a good job!


Send a certified email via Webmail

After purchasing an Aruba PEC, you need to log in to the Webmail panel to start using it and, therefore, to send messages through it.

To access the PEC mailbox, start the web browser and go to the Webmail web page for Aruba PECs. At this point, fill in the fields you see on the screen to log in: type your complete PEC address (for example ) in the  PEC address field  and enter the  password  associated with it, in the field you find at to follow. Then activate the Complete checkbox   or, in case you want to try the interface under development, the one called  Try the new webmail in beta . Once this is done, click the  Login button  to login.

After logging in, you will find yourself in front of the Webmail panel for managing incoming and outgoing messages. The main screen is composed, just to give you a few examples, of some panels that have the purpose of informing you about the state of use of the PEC and the latest messages received. In order to be able to send a PEC to a recipient, locate the New button , which you find at the top of the left pane and click on it, so as to start composing the certified mail message.

The PEC composition panel is simple and intuitive: in the From field you can find your PEC address, while in the To field you must type the recipient’s PEC address. If you need to send a PEC to several recipients, click on the wording Show CC and fill in the field that is shown to you, with the other PEC addresses to which to send the communication.

Now you have to fill in the Subject field , essential to make the recipient understand, in short, the purpose of the message you are sending. Try to be concise, indicating in the subject the necessary information that can summarize everything you want to communicate in a few simple words. For example, if you want to send a communication for the cancellation of a contract with a company, as the subject you must indicate something like “Cancellation of contract no. Xxxxxxx – Surname Name”. Although the Subject field is optional, it is good practice to fill it in, also in order to allow both the recipient and the sender to be able to identify the communication among the many present in their mailbox.

Once this is done, choose whether to activate the High Priority and Confidential buttons , so that the recipient can receive the message with the respective flags defined by these buttons. In the drop-down menu on the side, called Type of receipt , choose the type of receipt for the delivery confirmation to the recipient.

Finally, to fill in the message, use the HTML Text and Plain Text tabs . This last tab allows you to write a message without any formatting, while if you choose HTML text you can use different fonts of the character, change its size and set other parameters that you find in the style bar above the typing box.

If you need to attach documents, click on the Attach button at the top to explore the folders on your computer and search for files. Before sending the PEC, you can also save a draft, using the Save button , so that you can resume it at a later time. When you are done, you have to press the Send button  (above) to send the certified e-mail message to the recipient.

In the Inbox folder , you will receive two communications from the server regarding the status of acceptance and that of successful or unsuccessful delivery of the message. Always be careful to check this last communication, to be sure that the message has reached its destination. Otherwise, check the correctness of the recipient’s PEC address and try again, following the same instructions given in the previous paragraphs.

Send a certified email via the app

If you need to send PEC while you are away from home or office, you can use the official Aruba PEC Mobile app , available for free for  Android  and  iOS . Unlike other apps for sending emails, the advantage of using the official one is that you don’t need to configure any IMAP or POP3 parameters to manage email from a mobile device.

If you are interested in using this app, reach the links I have provided you: on  Android , tap the  Install button  and then  click Open . On  iOS , on the other hand, presses on  Get , unlock the download and installation via the Face ID , the Touch ID or the password of the iCloud account and, finally, press the  Open button .

At this point, start the Aruba PEC Mobile app , using its quick start icon that you find on the home screen. Once this is done, press the  Accept button  in order to access the Aruba PEC login screen. Then type the PEC address and the  password associated with it, using the text boxes you see on the screen. Then confirm the data by pressing the Login button , which will allow you to access the PEC.

After reaching the main screen of the app, to compose a certified mail message, tap on the icon with the  pencil symbol  located at the bottom. In the New message section , fill in the To field relating to the address of the recipient to whom you want to send the PEC and then type the subject of the communication in the Subject field .

In the area below, called Write email , type the body of the message. Unlike the version from Webmail, you are not allowed to use formatting styles. Once this is done, if you need to attach documents in the smartphone’s memory, press the icon with the symbol of a paperclip .

By tapping on the icon with the symbol , you can access a context menu to add other recipients to whom you want to send the message in copy ( Show CC ), add an attachment ( Add attachment ) or save a copy of the message to send it in a next moment ( Save draft ).

When you are ready, you simply have to tap on the icon with the symbol of an airplane , which you find located at the top, so as to immediately send the message to the recipients.

Send a certified email via e-mail client

You can also send a PEC from Aruba via an e-mail client. If you are looking for software suitable for this purpose for your computer, I can recommend Microsoft Outlook or Thunderbird , which are available for both the Windows operating system and macOS. On macOS, however, you can also use the pre-installed Mail client .

On the move, however, via smartphone and tablet you can use the official Aruba PEC Mobile app , which I told you about in this chapter , or use other apps such as Spark for iOS or Gmail and Outlook , available for both Android and iOS. If you want to know these software and apps in detail, I suggest you read my guide on e-mail programs or the one on e-mail programs.

In this tutorial, however, I will talk to you about the free Thunderbird software , to configure your certified mailbox via the IMAP or POP3 protocols of Aruba. First, download the client via the official website by clicking the Free Download button . By doing so, the .exe file on Windows or .dmg on macOS will be downloaded.

On Windows , double-click the .exe file and then click Yes in the User Account Control window. In the screen that is shown to you, click on the Next button twice consecutively and confirm the installation by clicking on the Install button . Finally, press the Finish button to close the screen. On macOS , on the other hand, double-click on the .dmg file and drag the Thunderbird icon into the Applications folder , as indicated on the screen you view.

Now, start Thunderbird via its quick launch icon, in order to access the main screen. Upon opening the program, you will be shown a window for setting up an e-mail account. In the Name field , type the name to display for the PEC and enter the PEC address and the password associated with it. Once this is done, click on Continue , for the software to automatically detect the IMAP / POP3 and SMTP data from the server.

I advise you to use the IMAP protocol instead of the POP3 one , so as to be sure of being able to access the PEC from any platform and device, finding all the messages received (the POP3 protocol, unlike the IMAP one, in fact provides for the use on a single device and deletion of messages from the remote server after they have been downloaded to the client). In addition to this, check if the data detected by the server is correct by clicking on the Manual configuration button and comparing it with those indicated below.


Full Name : Your name or certified mail address

Account name : the certified email address (e.g. or others with domain @, @, @, @, @, @pecditta. com)

Password : the password assigned to the PEC box

Use SSL : Activate

Authentication : Password

Protocol Type : IMAP

Host of the incoming mail server (IMAP) :

Incoming mail server (IMAP) port : 993

Outgoing mail server (SMTP) host:

Outgoing mail server (SMTP) port : 465


Full Name : Your name or certified mail address

Account name : the certified email address (e.g. or others with domain @, @, @, @, @, @pecditta. com)

Password : the password assigned to the PEC box

Protocol Type : POP3

Host of the incoming mail server (POP3) :

Incoming mail server port (POP3) : 995

Outgoing mail server (SMTP) host:

Outgoing mail server (SMTP) port : 465

Now, click on the Done button and then on the one called Skip integration , to complete the configuration procedure.

To write a new certified mail message, click on the Write button , which you find in the toolbar at the top and fill in the fields that are shown to you in the screen that opens. Then type recipients in the To field and indicate a subject in the respective text box. Then fill in the message in the box below, using the formatting tools that you find in the appropriate bar on the top margin.

If you need to save a local copy of the message, click the Save button . In case you want to attach documents, click on Attach , at the top right. After filling in all the necessary fields, click on the Submit button , located at the top left. It was easy, wasn’t it?

If, on the other hand, you intend to set up your Aruba account in another email client, please follow the instructions below.

  • Outlook (Windows) – click on the File button located at the top left and, in the screen that opens, presses the Add account button . If you don’t see the button in question, first press the  Account Settings  button twice in a row and then  click New .
  • Apple Mail (macOS) – select the Add account item from the Mail menu located at the top left. In the window that opens, choose  Other mail account…  and follow the instructions on the screen to configure your Aruba PEC account.
