SPF Records

To send notifications to your customers through Teachworks using your own company's email address, it's important that you add an SPF text record to your domain to maximize deliverability.
​
SPF stands for Sender Policy Framework. It's a method to prevent sender address spoofing by verifying sender IP addresses. Basically, when a sender adds an SPF text record to their domain (say, example.com), they are authorizing an email service provider, like teachworks, to send emails from @example.com. Non-authorized IPs will not be permitted to send from @example.com.
​
Without this record in place, receiving ESPs like Gmail and Yahoo are more likely to flag the email as spam.
​
In order to improve deliverability of your emails sent from teachworks, add the following SPF text record to your domain's DNS records:
​
​“v=spf1 include:mailgun.org ~all”
​
Changes to DNS records can take up to 24-48 hours to propagate.
