Setting Up SPF, DKIM & DMARC Records for BigChange Email Authentication

To ensure that emails sent via BigChange are not incorrectly marked as spam, it is essential to setup SPF and DKIM records for your domain. This guide will walk you through the steps required to configure these records, ensuring that your emails are authenticated and delivered successfully.

Understanding SPF, DKIM and DMARC Records

DKIM, SPF and DMARC are email authorisation methods that increase deliverability of your emails and decrease the chance they end up in spam, helping to make sure that your email reaches their intended recipients, as well as helping to improve your security and protect your brand reputation by preventing others from sending spoof emails using your domain.

• SPF (Sender Policy Framework) is an email authentication technique used to prevent
  unknown entities from sending messages on behalf of your domain by specifying
  exactly which IP addresses are allowed to send mail from that domain.
  
  
• DKIM (Domain Keys Identified Mail) is utilised to provide an additional measure of
  email authentication, giving confidence that the email received is from a pre-authenticated source/application by applying an encryption key and digital signature
  to verify that an email message was not forged or altered.
  
  
• DMARC (Domain-based Message Authentication Reporting and Conformance) is an
  email security policy that allows email senders to specify policies for how their email
  should be handled if it’s received by a receiving server.

Why BigChange Requires SPF and DKIM?

BigChange uses Amazon Simple Email Service (SES) to send emails on behalf of your domain. Setting up SPF and DKIM records ensures that spam filters do not block these emails, as the FROM address in your email must match the origin of the email (AWS SES for BigChange).

Requesting DKIM Records

To implement DKIM, you need to request DKIM records from BigChange by contacting the BigChange Support Team. The quickest way to do this, is to submit a ticket via the BigChange Help Centre; select the "Request a Change" form and the "DKIM Request" option. Ensure that the provided domain matches the domain you are using within the white labelling section of BigChange.

Conclusion

Setting up SPF and DKIM records is crucial for ensuring that your emails sent via BigChange are authenticated and not marked as spam. Follow the steps outlined in this guide to configure these records for your domain.
