Approve your sending domain

As of 27th April 2016, sending any emails from a custom email address requires you to verify and configure SPF and DKIM records for all active sending domains. This change has been brought on by MailChimp, more information about which can be found here.

This means that any email style that has a different sending address from '' must be approved before you can send emails from that address.

After the 27th of April any email sent using an email style with an unapproved email address will have the "from" address replaced with

There are two steps to approving your domain:

We can provide assistance to users in setting up their domain in TutorCruncher as part of our dedicated support package.

DNS Settings

Two DNS records are required to prove that you have the right to send emails from your domain. These records used to just be best practice but MailChimp are now making them required. To change them you'll need to log into your DNS provider, eg. GoDaddy , 123-reg or namecheap (this is generally the website where you bought your domain).

How do I find out where to add my DNS records?

We recommend using this free tool to look up your domain host provider. All you need to do is enter your company's domain name, e.g., to verify where your nameservers are hosted.

Once you have this located, you will need to log into the interface for your domain host provider and add create new TXT records. If you've done this kind of thing before you should be able to just copy & paste the values into your DNS, but please take notes of the caveats below.

Once you've set these values you can check to see if your domain is approved by going to your email style and clicking "Check Domain Status", you may need to refresh the page to view the result. Note that you may need to wait up to 24 hours after you update your DNS, but it generally takes minutes or seconds.

Type Host Value
TXT @ v=spf1 ?all
TXT mandrill._domainkey v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB;

As with so many things, it might not be quite that simple, there are a couple of possible things that could trip you up:

Only one SPF record is allowed

If you already have a TXT record with SPF information, you'll need to add Mandrill's servers to that record by adding in the record before the last operator (which is usually ?all, ~all, or -all) instead of adding a new record as shown above.

For instance, if you currently have a record that looks like:

v=spf1 -all,

you will need to change it to read

v=spf1 -all.

However, if you insert a new SPF record so your records read:

v=spf1 -all
v=spf1 -all

Then the sending domain will not be approved.

Some DNS providers require DKIM semicolons to be escaped

Some DNS providers escape semicolons for you while others require you to do it when you set up the record.

If the value above doesn't work, you might try adding \ before all ;:

v=DKIM1\; k=rsa\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB\;

Email Domain Verification

  1. Go to System > Settings > Email Styles, and select your Default Email Style so that you can add your domain details (e.g.
  2. Submit these changes and then refresh the page
  3. Click "Send Domain Verification email to ""
  4. The specified email address will now receive an email from Mandrill. You need to forward this email within 7 days to so that it can be verified.
  5. Once you have received confirmation from TutorCruncher (within 2 business days) that your sending domain has been verified, you can proceed to the last step.

The last step!

Please note you must now go to each of your email styles and click 'Check Domain Status'. If you do not do this, the domain will not approve itself!

If your email style has been approved, then you will be able to see a tick beside it from the email style list, and when you click on an email style, it will have 4 ticks:
