Vouchers as a present

Posteo vouchers for printing out

In just a few clicks, you can generate a voucher in your email account settings. It can then be sent via email to other Posteo accounts. If you’d like, you can add a personal message to the email. You can also write down the voucher code in a gift card that you can personalise.
If you would like a gift card with a Posteo design, you can also use our templates which can be found at the bottom of this blog post. These templates can be printed using a photo printer or a photo station at a retail store and then glued into a greeting card.

If you would like to print at such photo stations, save the images on a USB stick. You can then print out the desired template using the stick. We recommend using the size 10 × 15 cm (4 × 6 inches). This allows your printout to fit in most standard greeting cards. Paste your printed template inside or on the front of the card where you will write the voucher code and a personalised text.

You can find our templates below. Simply download the desired images on your hard drive or your USB stick.

Some tips for gifting vouchers

  • We recommend gifting our vouchers to people who already have an email address at Posteo. They will surely be happy to receive a voucher – and will also see it as a practical gift.
  • If you want to gift a voucher to a person who does not yet have an account with Posteo, first ask them if a Posteo voucher is a desired gift.
  • A new email account can also be opened using a gift voucher. However, once the gifted credit has run out, it will then cost 1 EUR per month. Therefore, you should consider this aspect with a bit of sensitivity.

Using vouchers for adding credit to email accounts

By the way, vouchers are not only suitable as birthday and holiday gifts. You can also use vouchers to add more credit for family members like children or your partner.

You can find instructions for generating and redeeming vouchers in our help section:

New from Posteo: Create S/MIME certificates and start using right away

Created on 30. April 2024, 15:00 | Category: Info

Dear Posteo Customers,

We’re adding to our offerings for end-to-end encryption and email signing: effective immediately you can use our service to easily obtain inexpensive S/MIME certificates for your Posteo email addresses with a single click.

S/MIME is a standard for end-to-end encryption that is used around the world and is already integrated into many email clients. An S/MIME certificate issued by a recognized certificate authority is displayed as trustworthy in email clients – and verifies the authenticity of an email address and the contents of an email. That means: more security in email communication.

For private users, obtaining certificates has for years been relatively complicated and cost-intensive, even though S/MIME certificates can play an important role in ensuring secure communication across email platforms. We want to encourage the use of S/MIME, and so effective immediately we are offering inexpensive certificates for your Posteo address(es) that you can create with just one click and start using right away. The S/MIME certificates come from a recognized certificate authority (Certum); emails signed with the certificates are displayed as trustworthy in email clients. The certificates are valid for one year and cost €3.65. You will be notified before the expiration date and given the option to renew. Certificates can also be obtained for aliases. You’ll find the new option in Settings under “My S/MIME certificates”.

S/MIME signatures are verified in Posteo webmail
S/MIME signatures are verified in Posteo webmail

To sign your emails with S/MIME, only you need a certificate; for encryption all recipients must also be using S/MIME. S/MIME works with almost all email clients (such as Thunderbird, Apple Mail, and Outlook) and effective immediately you can start using certificates obtained through Posteo with these clients.

We are currently at work on a browser plug-in for Posteo webmail and the Posteo web app. With this plug-in you’ll be able to sign your emails directly in Posteo webmail and the web app. You’ll also be able to encrypt and decrypt emails – without us, the email provider, storing your private key on our servers. This is the only way to ensure real and trustworthy end-to-end encryption.

S/MIME signatures are already verified and displayed in Posteo webmail and the Posteo web app. Some large companies, like DHL, and some government agencies as well have begun signing their emails with S/MIME, so that you can recognize the authenticity of an email at a glance.

For those interested in the technical details: here’s what happens when you generate a certificate “with a single click.”

Certificates are not server-generated at Posteo: if you create an S/MIME certificate in Settings, a key pair is automatically generated locally in the browser on your device. Your browser then generates a certificate signing request, and only this request (not the private key) is transferred via Posteo to the certificate authority (Certum), where it is signed and sent back, again via Posteo, to your browser. The browser then saves the certificate together with your private key in a file on your computer’s hard drive. The certificate can be installed in email clients. To do so you will need the installation password provided when you created the S/MIME certificate – please store it in a safe place. Throughout this process the private key continues to be stored locally on your device at all times. Or to put it another way: private keys, which are used to sign and decrypt emails, are never at any point in time available to either Posteo or the certificate authority (Certum) and are not saved by Posteo. To reiterate: This is important, because real end-to-end encryption means the email providers never have the end users’ private keys.

Best regards,
Your Posteo Team

Girls'Day 2024 at Posteo

Created on 26. April 2024, 15:45 | Category: Blog

Making coding exciting for girls: This is what our team set out to do again in 2024 for Girls’Day.
It was a great experience once again for us to welcome female students interested in computer science at the Posteo Lab located on top of Berlin’s Kreuzberg – and to give them insight into the job of a software developer.

Email workshop at Girls'Day 2024
Email workshop at Girls’Day 2024

Starting steps for computer science

After a round of getting to know each other, our developer Monika shared how she trained for her profession. She told the girls what subject matter should be expected when studying computer science and what job possibilities exist afterwards. She then answered questions regarding choosing a profession and everyday life on the job.

Workshop: How email protocols works

Afterwards, there was a more detailed look into working as a developer. Our team explained to the students what protocols are, what role they have in the global exchange of information – and how the SMTP protocol (Simple Mail Transfer Protocol) is used for transferring emails.

Finally, it was the girls’ turn: With help from Anne, a team leader from our technical support, they could communicate with an email server using SMTP protocol, enter commands and deliver emails from the command line.

Choosing a field of study or profession without gender stereotypes

Our Girls’Day Team enjoyed the day very much. “The girls were awesome and it was nice to see how motivated they are”, said Posteo developer Monika. “It was not just important for us to give them insight into software development. As women working in IT, we also wanted to show that they are not bound by antiquated gender roles. We hope that they had just as much fun as we did and that they have become even more confident about their potential career choices.”

Girls’Day is a day of action for career guidance in Germany. On this day, girls in the 5th grade and higher can gain more insight into jobs that are primarily chosen by men.
This includes software development. Posteo’s development team has a balanced ratio between men and women. Many of our features were programmed by women: for example the Posteo migration service, our mobile user interface, the attachment browser with photo stream – and also our new dark mode. But it’s not like that everywhere: In computer science studies and in the technology sector, women in Germany are still strongly under-represented.

New security certificate

Created on 23. February 2024, 11:35 | Category: Info

Dear Posteo customers,

We are updating our main security certificate. Security certificates are only valid for a specified time period and need to be renewed from time to time.

In most cases, you will not notice any change.
All current clients like Thunderbird or Outlook will automatically find the new certificate. You do not need to do anything. However, should your client display a certificate error during this changeover process, please restart your client. This should fix the error.

If you manage the trustworthiness of certificates manually, you can find the fingerprint for the new main certificate below. You can also find complete fingerprints for all certificates in our legal notice.

New fingerprint for the TLS security certificate for posteo.de:

SHA1: ED:87:9A:C6:E6:2E:72:82:42:AD:30:D9:05:38:30:34:7C:47:2F:24

Now available: posteo.com and additional Posteo domains

Created on 15. December 2023, 13:45 | Category: Info

Dear Posteo customers,

We are expanding our range of services: From now on, accounts can also be registered with the email domain @posteo.com. Additionally, we offer the domains @posteo.us, @posteo.ca, @posteo.uk, @posteo.ie, @posteo.es, @posteo.at, @posteo.ch, @posteo.nl, @posteo.be, and @posteo.lu.

#more#

Previously, accounts could only be registered with either @posteo.de or @posteo.net endings. Many of you have asked for these additional options.

If you prefer one of the new domains for your existing account, you can now rename it easily in the settings via “Email aliases”. Your previous address will then be converted into an alias, so that you can continue to receive emails to that address.
If necessary, you can find further information in our help section.

There are many other top-level domains (the address part after “@posteo.”) also available for Posteo email aliases, such as .me or .eu.

By the way: Your Posteo address can only be registered by you for the other Posteo domains. For example, if you have the address mymail@posteo.de, only you can register the address mymail@posteo.com.

Best regards,
Your Posteo Team
