GDPR For Email Verification Cusomters! (Get Ready By May)
Why is authorisation so important?
SPF and DKIM are like a signature proving that the email was actually sent by the sender and is not a scam. Even the best email sender is unable to deliver your emails without the correct authorisation settings from your domain. To be able to deliver and inbox your emails you must authorise your email sender with well formatted SPF and DKIM settings. It is also recommended to have a DMARC to keep checking if your SPF and DKIM are passing.
Contact your email sender support for these details. Without having correctly set SPF and DKIM records 5-10% of your emails might bounce.
Be aware when you set up a new DNS record for any of these, you need to wait 72 hours for the DNS changes to fully propagate.
SPF: Sender Policy Framework
SPF is a simple email-validation system designed to detect email spoofing by providing a mechanism to allow receiving mail exchangers to check that incoming mail from a domain comes from a host authorised by that domain's administrators. You will need to add a value to your domains DNS lising servers and IP's that are allowed to send emails on your behalf.
Never send an email without correctly set SPF. Contact your email sender for further information and help on how to set up your SPF. Alternatively you can use the following pages to create and verify your SPF:
DKIM: Domain Keys Identified Mail
DKIM is an email authentication method designed to detect email spoofing. It allows the receiver to check that an email claimed to come from a specific domain was indeed authorised by the owner of that domain. It is intended to prevent forged sender addresses in emails, a technique often used in phishing and email spam.
While DKIM is important, generally correctly set SPF is enough to deliver your emails. Contact your email sender for further information and help on how to set up your DKIM.
DMARC: stands for "Domain-based Message Authentication, Reporting & Conformance". It is an email authentication protocol. It builds on the widely-deployed SPF and DKIM protocols, adding a reporting function that allows senders and receivers to improve and monitor protection of the domain from fraudulent email.
