Adding DNS Records for Sending Domains
Cool Life CRM requires that all sending domains have the proper SPF and DKIM records in place in order to send marketing email via Mandrill, our third-party email service provider. SPF and DKIM records are special DNS records which verify your ownership of the domain, and give Mandrill permission to send mail on your domain's behalf, which is essential for optimal deliverability. To add the SPF and DKIM records for your sending domains, you'll need to add records of type TXT through your hosting provider, domain registrar, or DNS provider.
If you don't yet have an SPF record, add one for your domain. At a minimum, the value should be the following if you're only sending mail through Mandrill for that domain:
v=spf1 include:spf.mandrillapp.com ?all
If you already have a TXT record with SPF information, you'll need to add Mandrill's servers to that record by adding include:spf.mandrillapp.com in the record (before the last operator, which is usually ?all, ~all, or -all).
Add a new TXT record with the name mandrill._domainkey.yourdomain.com (just replace yourdomain.com with the domain you're setting up).
The value for the record should be one of the options listed below. There are two options because the record contains semicolons, and some DNS providers escape semicolons for you while others require you to do it when setting up the record.
With semicolons escaped:
v=DKIM1\; k=rsa\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB\;
With semicolons unescaped:
v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB;
Here are links and information for several hosting and DNS providers.
Many hosting providers offer CPanel to manage your domain. CPanel instructions are often similar among hosts that offer this option.
|DKIM record typically escaped automatically.
The 'name' of your DKIM record should be
mandrill._domainkey.yourdomain.comwhere yourdomain.com is replaced by the domain name where you're adding the record. Most hosts that utilize cPanel don't automatically add the domain name to the end of the record name.

If your host or DNS provider doesn't appear here, contact their customer support or help files for more information. Each host may handle the adding or editing of records differently, so your host's technical support or documentation is the best resource for any limitations or formatting specific to that provider.
After you've added the appropriate DNS records, it can take up to 24 hours for the changes to take effect. If there's still errors when validating your domain, there are some third-party resources you can use to check your records or for other details if needed:
Check the SPF validator here. Enter your domain name in the first text box and click Get SPF Record for a diagnostic of your SPF records.
Check whether your DKIM record is valid using the DKIMCore validator. Enter mandrill as the selector and your domain name.
The SPF validator looks for a TXT record with the appropriate SPF information. If your domain has an SPF type record, it's best to add a matching TXT record for compatibility.
If you already have an SPF record, edit that record instead of adding a new one. The specs for SPF require that there only be one TXT record with SPF information.
If you've added the DKIM record and are still seeing that it's missing, your DNS provider may require the record be formatted differently. The DKIM record Mandrill provides has semicolons escaped with a backslash, so the record starts with this:
and ends like this:
Some DNS providers don't require semicolons be escaped. If you see issues, try removing the backslashes right before semicolons at the beginning and end of the record.
Some DNS providers take longer than others to publish and push the record. If you're adding a completely new record, those often validate within 10-15 minutes. Changing records can take longer, but can vary based on your DNS provider and TTL for the record.
