Transforming Email Deliverability for Mid-Sized Firm

The Challenge

A mid-sized firm was grappling with significant email deliverability issues. Their emails frequently landed in recipients’ spam folders, severely impacting client communications and marketing campaigns.

  • Low Email Open Rates: Recipients were not engaging with the firm’s emails due to them being marked as spam.
  • High Bounce Rates: A substantial number of emails were being returned as undeliverable.
  • Frequent Spam Reports: Many recipients flagged the firm’s emails as spam, further harming their sender reputation.


RealBytes implemented a comprehensive email authentication strategy to address these challenges. The strategy included:

  • SPF (Sender Policy Framework): Defined authorised mail servers allowed to send emails on behalf of the firm’s domain.
  • DKIM (DomainKeys Identified Mail): Enabled cryptographic signatures for emails, ensuring message integrity and authenticity.
  • DMARC (Domain-based Message Authentication, Reporting & Conformance): Implemented a policy that aligned SPF and DKIM mechanisms and provided feedback on email authentication.

The Outcome

  • Email Deliverability Rate: Increased from 70% to 95%, ensuring more emails reached their intended recipients.
  • Open Rates: Improved by 30%, indicating higher engagement from recipients.
  • Spam Reports: Reduced by 50%, enhancing the firm’s sender reputation.
  • Bounce Rate: Decreased by 40%, indicating a more effective email delivery system.

By implementing these email authentication protocols, RealBytes significantly improved the firm’s email deliverability, leading to better client communication and more effective marketing campaigns.
