It is very common for spam emails to claim to be from one place, when in fact sent from completely different mail servers. The same behaviour is what happens when your sender email address is sending mail through our mail servers. It can be perceived as a negative thing by a spam filter when it tries to assess your email.
The spam filter looks through many other parameters as well before it classifies a mail as spam or not.

To reduce the risk of being perceived negatively by a spam filter, it is possible to add a SPF and DKIM setting on the domain used by the sender address. It works as a confirmation on the domain that the mail that are sent through our mail servers are not “fishy” in any way.

To do that you need to go into the DNS-settings, also called name server settings, of your domain and add the following:

  • SPF record

  • DKIM

  • Sender ID

We will guide you through the steps for each setting. Step one is to make sure that you, someone in your team or the support of your web host has access to the DNS settings of your domain.

Step 1. Find out who is managing your domain / name servers

(1) Go to www.who.is

(2) Enter your domain name and click on the magnifying glass

(3) Scroll down to “nserver”. There you can see exactly where you need to go to add the correct settings.

Once you know where your domain is managed, you can either choose to contact the support of your web host and ask them to help you add SPF, DKIM & Sender ID according to the instructions below or log in to the control panel of your web host and add it yourself under the domain's DNS settings.

Step 2. Add SPF-Record


What is SPF Record?

SPF-Record (Sender Policy Framework) is a simple email-validation anti-spam technique designed to reduce the risk of being marked as spam by the receiving mail exchanger (e-mail client). The mail exchanger checks that incoming mail from a domain (the sender) comes from a host authorized by that domain’s administrators (Get a Newsletter).

The list of authorized sending hosts for a domain is published in the Domain Name System (DNS) records for that domain in the form of a specially formatted TXT record. By adding an SPF record you have the ability to specify which servers are allowed to send email from your domain, eg, Get a Newsletter. This makes it harder for someone to prevent spammers from using your domain as a sender of spam

How to add a SPF-record

The SPF-Record should be added to the DNS settings of your domain should include the following text:

include:spf.gansend.com

The exact order and approach to to this may look different for different web hosts but the information that needs to be added in the different fields is:

Type: TXT

Data: include: spf.gansend.com

The rest of the fields can be left as they are.

Example of what the SPF Record can look like if it's entered correctly:

v=spf1 mx a include:spf.gansend.com ~all

Check that SPF is entered correctly

You can double check if your SPF record is entered correctly by:

  1. Go to http://www.kitterman.com/spf/validate.html

  2. In the "Domain name:" field, type your domain and click Enter

  3. Under "Found v = spf1 record for domain.com:" SPF-Record for your domain will appear. Make sure the text "include: spf.gansend.com" is included.

  4. If it is not there, try to enter the SPF record as above once more, or ask the support of your web host to help you. Note that it can take up to 48 hours for DNS settings to go through.

Step 3. Add DKIM


What is DKIM?

DKIM stands for Domain Keys Identified Mail, and is a verification that helps the receiving server to verify that the email was actually sent from the domain that is the sender. It works as a digital signature that confirms that it's really you who sent the email and that no one has changed the email since you sent it.

You could say that DKIM is like that silver thread or water mark on banknotes, which proves that it is genuine.

How to add DKIM

The DKIM setting is made in the DNS settings of your domain and should be entered as a subdomain. The exact order and approach to to this may look different for different web hosts but the information that needs to be added in the different fields is:

  • Subdomain: getanewsletter._domainkey

  • Type: CNAME

  • Data: key1._domainkey.gansend.com

The rest of the fields can be left as they are.

Example of what DKIM would look like if Get a Newsletter had implemented it:

getanewsletter._domainkey.getanewsletter.com CNAME key1._domainkey.gansend.com

Check that DKIM is entered correctly

1. Go to the Google Admin Toolbox

2. Delete "domännamn" and fill in your domain instead. For example, if you would like to check the DKIM for example.com, type: getanewsletter._domainkey.example.com

3. If the DKIM setting has been set correctly, you will see a long text below ;ANSWER


Example for Get a Newsletter:

getanewsletter._domainkey.getanewsletter.com. 3598 IN CNAME key1._domainkey.gansend.com.

key1._domainkey.gansend.com. 28 IN TXT "k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC6cEgZWVkOA8vU/rSpaLNoLvW83+NXzYVWvqlvkfYuoRTlfw36vnTUK2o+2Yp4cgbB4F9m9G/qKAlLBsrpb4d5RIouz83BswBYzFzxQOevUiIoyXWkeAy4q9DOuGw8v0G467pN7z+/4iGgxxr2bad1UbIctKyuY9MLvHpBG697BQIDAQAB"

4. If DKIM is not added correctly, you will not see anything below ;ANSWER. Make a new attempt to enter the DKIM setting as above, or ask the support of your web host to help you out. Note that it can take up to 48 hours for DNS settings to go through.

When the DKIM is registered on your domain - send an email to support@getanewsletter.com, and we will fix the last thing needed from our side for the verification to take full effect.

Step 4. Sender ID

What is Sender ID?

Sender ID is based on and very similar to SPF record, and is also done in the DNS settings, but looks at a few other things so they complement each other.

How to add Sender ID


Sender ID is also added to the DNS settings as well and what needs to be added is:

Type: TXT

Data: spf2.0 / mfrom, pra a mx include: spf.gansend.com ~ all

The rest of the fields can be left as they are.
