In this guide we’ll walk you through setting up domain records DKIM, SPF, DMARC and CNAME (domain router) with the domain provider Wedos. These records are required to securely send bulk emails from the Boldem app and to prevent them from ending up in the spam folder.

1. Log in to your account in the Boldem app.
2. In the left menu, select Settings and click Domains.

3. If you didn’t enter a sending domain name when creating your account, click the + Add sending domain button. If you already added the domain when creating your account and see it in the list, continue with step 4 below.

4. Enter the sending domain name and confirm with the Create button. Enter the domain without www, e.g., example.cz.
   

5. Click the Details button for the domain in the list.
   

6. Click the Domain Settings tab.

7. The page will display the DKIM signature details, the SPF record, and the CNAME record. Keep this window open; you’ll need them shortly.
8. In the new window, sign in to your account to manage your domain with Wedos at https://client.wedos.com/dns/.
9. In the domain list, click the domain you want to edit.

10. In the left-hand menu, click Edit DNSThe Domain Name System (DNS) is a hierarchical and distributed naming system for computers, services, and other resource... Records.

11. An overview of DNS records and an option to add a new record will appear. Click new record.

12. A menu to add a record will appear.

DKIM Record Settings

1. In the Wedos interface, select TXT from the Type drop-down menu.
2. In your Boldem account, in the DKIM signature section, copy the required record from the Name custom field by clicking the copy icon.
   

3. In the Wedos interface, paste the copied value into the Name field.
4. Do not change the TTL value.
5. In your Boldem account, in the DKIM signature section, copy the required record from the custom field Value by clicking the copy icon.

6. In the Wedos interface, paste the copied value into the Data field.

7. Save the record by clicking the Save record button. The resulting record will look something like this:

SPF Record Settings

Edit an existing SPF record

If you find a TXT record in the list of domain records that contains SPF data for your domain (e.g., for example.cz), you should edit that record instead of creating a new one. Example of an existing record:

1. Click the edit icon on the row to the left of this record.

2. A new dialog to edit the data will appear. In the Data field, insert the string include:spf.boldem.cz before the ~all tag.

3. Save the record by clicking the Edit record button.

Add a new SPF record

If you don’t find a TXT record in the list of DNS records that contains SPF information for your domain, follow these steps:

1. In the Wedos interface, click the new record button and choose TXT for Type from the drop-down menu.
2. Leave the Name field empty.
3. Do not change the TTL value.
4. In your Boldem account, in the SPF record section, copy the required entry in the Value custom field by clicking the copy icon.

6. In the Wedos interface, paste the copied value into the Data field.

7. Save the record by clicking the Save record button. The resulting record will look something like this:

DMARC record settings

Edit existing DMARC record

If you find a TXT record in the list of domain records that contains DMARC information for your domain (e.g., for example.com), you should modify that record instead of creating a new one. Example of an existing record:

v=DMARC1; p=none; rua=mailto:dmarc@example.com

1. Click the edit icon on the row to the left of this record.
2. A new dialog for editing the value will appear. In the Data field, add the value you copy from your Boldem account in the Value section. Copy only the part of the string that starts with mailto. Example DMARC value in Boldem:

3. In this case, copy only the part mailto:pdgpt8b8@dmarc.boldem.cz.
4. At the end of the part of your existing record that starts with rua, add a comma and paste the copied section of the record. The resulting version of the example above would be:

v=DMARC1; p=none; rua=mailto:dmarc@example.com,mailto:pdgpt8b8@dmarc.boldem.cz

5. Save the record by clicking the Edit record button.

Add new DMARC record

If you don’t find a TXT record containing DMARC information for your domain in the list of domain records, follow these steps:

1. In the Wedos interface, click the new record button and choose TXT for Type from the drop-down menu.

2. A field to fill in will appear.
3. In the Name field, enter the value you copy from your Boldem account in the DMARC record section in the Name custom field by clicking the copy icon.

3. Do not change the TTL value.
4. In the Data field, paste the code you copy from your Boldem account’s DMARC record in the Value custom field by clicking the copy icon.

5. To save the record, click the Save record button.

CNAME record settings (domain router)

1. In the Wedos interface, click on new record again for the domain.
2. In the drop-down menu Type, select CNAME.
3. In your Boldem account, in the CNAME (domain router) section, copy the required record in the Name custom field by clicking the copy icon.

3. In the Wedos interface, paste the copied value into the Name field.
4. Do not change the TTL value.
5. In your Boldem account, in the CNAME (domain router) section, copy the required record in the custom field Value by clicking the copy icon.

6. In the Wedos interface, paste the copied value into the Data field.

7. Save the record by clicking the Save record button. The resulting record will look something like this:

Record activation

After adding all required records, you still need to apply the changes with Wedos. Click the Apply changes button above the records:

Domain Record Validation

After you set up the records, it can take some time for the information to propagate to DNS servers. For most providers this should happen within an hour, and usually no later than 24 hours.

After setting up all records, go to Settings/Domains in the Boldem app, select your domain, and on the Domain Settings tab click the Check settings button.

The ideal result of the check should be green-highlighted information for each record:

If domain changes don’t take effect after 24 hours, contact your domain provider’s support to verify that the records were entered correctly, then repeat the domain verification process in the Boldem app.

Missing certificate for HTTPS

When validating the CNAME record, you may encounter the following error:

The CNAME record is configured correctly. However, to enable full functionality you still need to set up a certificate for HTTPS.

This error occurs when the domain contains a CAA (Certification Authority Authorization) record. A CAA record allows domain owners or administrators to declare which certificate authorities may issue SSL certificates for the domain.

When using Boldem, we use a Let’s Encrypt certificate, so add a new record to your domain with this identifier. Leave existing CAA records unchanged.

Example of adding a record with provider Wedos (Vedos):

1. After logging in to the domain administration, click the domain you want to edit.
2. Select the Edit DNS records. An overview of the domain’s records will appear.
3. Check whether a CAA record containing the keyword “letsencrypt.org” exists among the records, and if not, add one by clicking new record.
4. Leave the Name field blank and keep TTL at its default. In the Type field, select CAA.
5. Enter the following in the Data field:
   0 issue “letsencrypt.org”

6. Click Save record.

The resulting CAA record:

Confirm by clicking the Apply changes button.

Wait 60 minutes and try verifying the domain records in the Boldem app again. If the error persists after another 24 hours, contact customer support.
