Email Deliverability Explained
Email deliverability is the ability of an email message to successfully reach your subscribers’ inboxes without being flagged as spam or landing in a junk folder.
It is presumably the most critical aspect of email marketing, as the primary goal of sending emails is to ensure the message actually reaches the intended recipient before they can read it.
Let’s understand the main factors that impact email deliverability:
- Email sender reputation: Your sender reputation, which includes the reputation of your email ̛IP address as well as domain reputation, plays a significant role in email deliverability. ESPs and mail services assess it to determine whether your email should be delivered to the inbox or filtered as spam.
- Email authentication: Implementing authentication protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) can help verify your authenticity and reduce incidents of email spoofing.
- Email engagement: Your email content and the level of engagement it receives matters. Irrelevant, poorly formatted, or excessively promotional content can trigger spam filters.
- Email list hygiene: Maintaining a clean email list is crucial. Besides cleaning your lists, you should segment them and use an email segmentation strategy to make your emails more relevant to subscribers. This translates to better engagement, which then gets you better deliverability.
- Sending spam emails: High numbers of recipients marking your emails as spam can negatively impact your sender reputation and email deliverability. It’s important to provide a one-click unsubscribe option and honor such requests promptly.
- Email bounce rates: A high rate of bounced emails, whether due to invalid email addresses or other issues, can affect your deliverability in the future.
- Frequency and consistency: Sending emails too frequently or inconsistently can lead to deliverability problems. Spread it out and be patient!
- Compliance with CAN-SPAM and GDPR: Adhering to email marketing regulations is essential for email deliverability. As a bonus, it helps build trust with your subscribers.
To maintain good email deliverability, you need to monitor and improve these factors, stay informed about industry best practices and changes in email technology, and use email deliverability tools.
