How do I link a LWS domain name to the Mailjet service?

Procédure

This guide explains how to connect your domain name managed at LWS to Mailjet in order to validate your [ADDRESS] domain and authenticate your emails with SPF and DKIM.

This setup allows Mailjet to be recognized as an authorized service to send emails with your domain. It also helps limit the risk of your messages being [PERSON_NAME] suspicious or placed in spam.

Before you begin

You must have the information provided by Mailjet for your domain. [PERSON_NAME] are found in your Mailjet account, in the management of sending domains and SPF/DKIM authentication.

Mailjet may ask you to add several DNS records, generally:

• a TXT record for domain validation;
• an SPF record;
• a DKIM record.

Retrieve the records to add in Mailjet

Log in to your Mailjet account.

Then go to the section for managing your sending domains. Depending on the Mailjet interface used, this section may be found in:

Account settings > Sender domains and addresses

Add [PERSON_NAME] not already done.

Then open the domain validation or authentication options.

Mailjet then displays the DNS records to create. Keep this page open: you will need to copy the Name, Host or Value fields indicated by [ADDRESS] LWS DNS zone.

Access your domain's DNS zone at LWS

Log in to your LWS customer area.

From the list of your services, click Manage next to the relevant domain name.

In the Domain management section, click DNS zone.

You will arrive on the page where you can add, modify, or delete the domain's DNS records.

Add the Mailjet validation record

In the [ADDRESS] DNS zone, add a new record of type TXT.

In the Name or Host field, enter the value requested by Mailjet.

In the Value field, paste the TXT value provided by Mailjet.

Choose a standard TTL, for example 6h, [PERSON_NAME] Add.

Once the DNS record has been created, click the “Verify now” button in the MailJet interface.

The “Validation successful” screen appears. It allows you to configure your SPF and DKIM records for your domain or return to your domain list.

Add or modify the SPF record

SPF makes it possible to indicate which services are authorized to send emails with your domain name.

In the DNS zone, first check whether there is already a TXT record starting with:

v=spf1

If no SPF already exists

Add a new record of type TXT with the following information:

Then save the change.

If an SPF already exists

Do not create a second SPF. Modify the existing record to add Mailjet.

For example, if your current SPF is:

v=spf1 include:exemple.com ~all

you can complete it as follows:

v=[PERSON_NAME] include:exemple.com include:spf.mailjet.com ~all

Add the Mailjet DKIM record

DKIM allows Mailjet to sign emails sent with your domain. [PERSON_NAME] helps email services verify that the message has not been altered and really comes from an authorized service.

In the [ADDRESS] DNS zone, add a new record of type TXT.

Fill in the fields with the information provided by Mailjet.

The DKIM name usually looks like:

mailjet._domainkey

The DKIM value is a long key often starting with:

k=rsa; p=...

Copy this full value from Mailjet, without adding spaces or modifying the text.

This key is found in your Mailjet account under the SPF/DKIM Authentication section

Then click Add or Save.

Verify the configuration in Mailjet

After you have [PERSON_NAME] DNS records in the LWS Panel, go back to your Mailjet account.

Go to Account settings > Sender domains and addresses.

Select your domain and you [PERSON_NAME] SPF and DKIM are correctly configured.

If your domain is properly authenticated, you will see a green mark next to SPF and DKIM.

Do the domain MX records need to be changed?

In most cases, no.

Mailjet is mainly used for sending marketing or transactional emails. MX records are used to receive emails for the domain.

Do not modify your domain's MX records unless Mailjet or your email configuration explicitly asks you to.

Common issues

Mailjet does not validate my domain

Check that the validation TXT record has indeed been added in the DNS zone actually used by your domain.

If your domain does not use the [ADDRESS] DNS servers, the [ADDRESS] DNS zone of the LWS Panel will not be taken into account. In that case, add the record with the provider managing your DNS.

Also check that the Name and the Value fields match [PERSON_NAME]>

SPF is rejected or shown as invalid

Check that there is only one SPF record for the domain.

If an SPF already exists, it must be modified to add:

include:spf.mailjet.com

You must not create a second TXT record starting with v=spf1.

DKIM remains in error

Check that the DKIM record name was not entered twice.

For example, if Mailjet displays:

mailjet._domainkey.yourdomain.com

in the LWS Panel, generally enter:

mailjet._domainkey

Also check that the DKIM key has been copied in full, without any added line break or removed character.

My emails [ADDRESS] must also continue to work

If you also use [ADDRESS] emails to send messages with the same domain, the SPF must authorize both LWS and Mailjet.

In that case, do not replace your existing SPF without checking its content. [PERSON_NAME] Mailjet authorization in the existing SPF record.
