Why Is Verifying the Sender Important?
Verifying the sender in email marketing is crucial for maintaining
trust and credibility with your audience. It ensures that your emails are authentic, reducing the risk of your messages being marked as
spam or, worse, being involved in a phishing attack.
SPF (Sender Policy Framework): This verifies that the email comes from an authorized server.
DKIM (DomainKeys Identified Mail): This adds a digital signature to your emails, confirming that the content has not been altered.
DMARC (Domain-based Message Authentication, Reporting, and Conformance): This policy helps prevent email spoofing by aligning SPF and DKIM.
What Are SPF, DKIM, and DMARC?
SPF: SPF is a record published in your DNS that specifies which mail servers are permitted to send email on behalf of your domain.
DKIM: DKIM provides a cryptographic signature that verifies the email content is authentic and has not been tampered with during transit.
DMARC: DMARC builds on SPF and DKIM by adding a layer of policy enforcement, giving domain owners the ability to instruct email receivers on how to handle unauthenticated emails.
Set up an SPF record in your DNS settings.
Configure DKIM by generating a public-private key pair and publishing the public key in your DNS.
Create a DMARC policy to specify how email receivers should handle messages that fail SPF or DKIM checks.
How Does Sender Verification Impact Deliverability?
Proper sender verification significantly improves email deliverability by ensuring your emails reach the inbox rather than the spam folder. ISPs and email providers use SPF, DKIM, and DMARC records as part of their spam filtering criteria, so having these records in place can enhance your
sender reputation.
Not updating SPF records when adding new mail servers.
Incorrectly configuring DKIM keys, leading to verification failures.
Setting overly aggressive DMARC policies without proper monitoring.
Conclusion
Verifying the sender in email marketing is not just a best practice; it’s a necessity for ensuring the security and effectiveness of your campaigns. By implementing SPF, DKIM, and DMARC, you can mitigate risks and improve your
email deliverability, ultimately leading to better engagement and trust with your audience.
