Factors Affecting Email Deliverability

Factors decide if your emails go to the inbox or spam, affecting email delivery. Let's explore some of the key factors that affect email deliverability and discuss strategies to overcome them:

Factors Affecting Email Deliverability

A. Sender Reputation

ISPs and Email service providers check the quality of your email address and domain. They do this to determine where emails should go.

This verification determines if the inbox receives your emails or if they go to the spam folder. If you have a good reputation, people trust you more, and your emails are more likely to reach their destination. It's like having a golden ticket for email delivery!

  • Avoid high bounce rates and regularly remove invalid email addresses.

  • Authenticate your emails using SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to improve trust and verify sender identity.
  • Regularly review and manage your email-sending practices to adhere to best practices.
Tips for Maintaining a Good Reputation:

B. Email verification

SPF, DKIM, and DMARC are verification protocols that help validate the authenticity of your email messages.

SPF (Sender Policy Framework) determines the IP addresses that can send emails on behalf of your domain.

DKIM (DomainKeys Identified Mail) applies a digital signature to your emails, guaranteeing that they remain untampered with during transit.

  • Monitor email metrics, such as open rates and click-through rates, and act on non-responsive subscribers.
