To guarantee a secure delivery rate, Quentn always automatically authenticates your emails with DKIM and also ensures that your emails pass SPF checks.
Email authentication - what does this actually mean?
Individual Internet Service Providers (ISPs) take extensive precautions to protect their networks from spam.
If the sender address was sent by a Freemailer (such as gmail, yahoo, web.de, gmx etc...), the provider knows that Gmail & co. certainly did not send this email themselves and will issue warnings to the recipient, or immediately label this email as spam.
This process is called email authentication: ISPs can determine whether the incoming email is really from the sender named in the email.
DomainKeys is based on asymmetric encryption. A digital signature is added to the header of the emails, which is assigned to your domain and is used for all outgoing emails. The receiving server then queries the official key, which is available in the Domain Name System (DNS) of the domain.
The SPF (Sender Policy Framework) is another spam protection method used for sender authentication. Additional information (detailed information about the sending mail servers) is stored in the DNS records of a domain in the form of SPF records. The receiving email server can use the SPF record of the domain to check whether the received emails are from an authorised email server or not. In the latter case, the email can be identified via the SPF spam protection and declared as spam.
The benefits of Quentn's standard authentication
All emails are always protected with Quentn's standard authentication. This has several benefits for you:
- Your emails have DKIM and SPF authentication.
- You don't have to worry about anything or perform any advanced DNS settings on your shipping domain.
It isn't possible to turn off Quentn's standard authentication. However, you can choose to set up your own authentication in addition to Quentn's. This can provide you with additional advantages when sending emails.
Your own domain verification
If you are the owner of your own domain, you have the opportunity to set up your own DKIM and SPF verification. This way, you allow Quentn to use your domain information in the email header. This improves the delivery rate of your emails and helps you to look more professional.
To achieve this, you need to make some changes to the DNS settings of your domain. It might be worth consulting your trusted technician for this.
Benefits of your own domain verification
- Quentn's authentication information ("sent via m-2.eu-1.quentn.com") disappears for the recipient and is replaced with your domain name. (This is not true for all email websites and programs, but certainly for most).
- The probability of your emails ending up in the recipient's advertising or spam folder is reduced.
Requirements for your own domain verification
If you fulfill all of the below criteria, we recommend that you verify your domain with Quentn:
- You own your own domain (e.g. "Example.de").
- You already have an email address for your own domain (e.g. John.firstname.lastname@example.org).
- You (or a trusted technician) are able to carry out a few DNS settings on your domain.
Verifying your own domain
Before you get started, we would like to give you some information:
- Although verifying your domain is recommended for Quentn users, it is an optional step!
- To verify your domain, you must carry out the Name server settings (DNS) on your domain. If you don't know where to find the DNS settings on your domain, contact your domain service or ask an online specialist.
Step 1: Create the domain
- In the menu, click on Email on the item Verified domains.
- Click on the button + Create domain
- Enter your domain here and click on Create.
Step 2: Verify the domain
- In the overview of the verified sender domains for the domain you just created, click on Actions -> Verification info.
- You will now be shown DNS entries. Open a new tab and log into your host (e.g. 1&1 or GoDaddy etc...) and go to the corresponding menu item to carry out the two TXT records (SPF and DKIM).
- Log into your domain and open the DNS settings.
- Insert the DNS records.
- If the domain has been verified, a note will appear in the overview of your verified sender domains.
Set DNS entries
This article will share some examples of setting the necessary DNS entries for your domain verification.
