DKIM, SPF and DMARC to avoid the trash can and get higher opening frequency

The settings below are made by your domain name provider. If you are sending email campaigns/mailings from multiple domains, follow these steps for each domain. 

To set the DKIM:

DKIM stands for "DomainKeys Identified Mail" and is an email authentication technique that verifies that a message was sent from a legitimate user of an email address. It is designed to prevent e-spoofing or spoofing (communication sent from an unknown source that is disguised as a source known to the recipient).

Rule supports DKIM and to set it up you need to add a CNAME.

A Canonical Name record (abbreviated CNAME record) is a type of resource record in the domain name system (DNS) that is used to indicate that a domain name is an alias for another domain (the canonical domain) in your DNS. 

The following is added:

keyse._domainkey.xxx.se pointing to keyse._domainkey.rulemailer.se

xxx.se =your domain, for example. alright.se

See here:

1. Click "Add subdomain" and fill in: Subdomain: keyse._domainkey

2. Select CNAME and then Data: keyse._domainkey.rulemailer.se

To set the SPF:

The Sender Policy Framework (SPF) is a simple and smart way to increase the chances of the newsletter being placed in the recipient's inbox instead of being flagged as spam. 

In short, it's a system to increase security by email and prevent others from sending you email in your name. With SPF in place, your domain will decide who has the right to use your domain as the sender.

Domain name: Public services of organisations (such as e-post And webbplatser) and individual computers can often be accessed by using the domain name. 

When you send emails via Rule, it is good that you "authorize" our server to send emails in your name. Example: nyhetsbrev@dittföretag.se

Since the change should be made on your domain name, you need to log in to your DNS hosting, ex Loopia.se that we use in this example. It is usually the IT department internally who has an eye on the company's domain and can assist with setting up SPF or check that it is set up correctly.

1. Log in to your DNS and select the domain name that you want to use as the sender.
2. Click DNS Editor.
3. Click "Add Record".
4. Select the type "TXT"
   TTL (Time to live) determines how often the value is checked in seconds, the default is 3600 and it is just fine.
5. In the Data box, add the following:v=spf1 a mx include:_spf.rulemailer.com ~all 
   

   

6. If you also have other mail servers, which you use to send emails in your name, it is only include:_spf.rulemailer.com that you should add to your existing SPF.

To set DMARC:

Domain-based Message Authentication, Reporting and Conformance (DMARC) is another way to verify incoming mail by authenticating the sender's domain. DMARC is especially important for mail sent to Outlook/Hotmail.

1. Log in to your DNS and select the domain name that you want to use as the sender.
2. Click DNS Editor.
3. Click "Add Record".
4. Select the type "TXT"
   TTL (Time to live) determines how often the value is checked in seconds, the default is 3600 and it is just fine.
5. In the name box, add the following value: _dmarc
6. In the data box, add the following: v=DMARC1; p=none; rua=mailto:dmarc@rule.se; ruf=mailto:authfail@rule.se
