Here are some steps you can take to ensure emails from your learning platform are sent 

You should have come here from the process to Customise the address your learning platform emails come from - if not, have a look at that process before you proceed.

How to configure the SPF Record

To achieve this, Create a new DNS TXT record and copy/paste the below:

v=spf1 ?all

I've gone to configure SPF, but there's already an SPF record!

That's good news! You'll instead need to amend that existing record by adding the below into the existing record (before the last operator, which is usually ?all) 

What's this "mandrillapp" thing I see above?

Your learning platform uses a third party service called Mandrill that specialises in delivering email quickly, reliably and in high volumes when required. CourseGenius uses this service so we can focus on creating a great online learning platform instead of reinventing the wheel when it comes to email.

How to configure the DKIM record

To achieve this, add a new TXT record with the name (just replace with the domain you're setting up). and copy/paste the below:
v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB;
