Understanding e-mail Deliverability and Tracking e-mails

Email Deliverability refers to the ability of your email to successfully reach recipients’ inboxes, rather than being filtered into spam or blocked altogether. High deliverability rates mean that more of your emails land in recipients’ inboxes, leading to better visibility, engagement, and conversion potential. Deliverability is distinct from “Delivery Rate,” which simply indicates that an email was accepted by the recipient’s server. Deliverability focuses specifically on whether an email reaches the primary inbox.

Factors Affecting Email Deliverability:

• Sender Reputation

Sender reputation is one of the most critical factors affecting email deliverability. Email service providers (ESPs) evaluate sender reputation based on previous email behavior (such as bounce rates, spam complaints, and engagement). A positive reputation results in higher inbox placement rates, while a poor reputation often leads to messages being filtered as spam.

• Authentication Protocols

Authentication protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) help verify that an email is genuinely from your domain. Implementing these protocols enhances deliverability by preventing your emails from being marked as suspicious.

• Email Content Quality

The quality of your email content affects deliverability. Avoid spammy words or excessive punctuation, especially in subject lines (e.g., “Buy Now!!!” or “FREE!!!”). Include a balanced mix of text and images, use proper grammar, and maintain a professional tone. Content that appears “spammy” can trigger ESP filters, resulting in a lower deliverability rate.

• Clean Subscriber Lists

Regularly cleaning your email list is crucial for maintaining good deliverability. Remove inactive or invalid email addresses to reduce hard bounces, which can harm your sender reputation. A high bounce rate signals ESPs that your list may contain outdated or irrelevant contacts.

• Email Frequency and Consistency

Consistency in email frequency builds trust and familiarity. Sending too many emails in a short period may overwhelm recipients, leading to unsubscribes or spam complaints. Similarly, if you send emails too infrequently, subscribers might forget about your brand, increasing the likelihood of spam reports.

Tracking Email Performance: Key Metrics

Tracking email metrics provides insights into how your audience engages with your content and allows you to refine future campaigns. Here are the essential metrics to consider:

1. Open Rate

Open rate is the percentage of recipients who open your email. It’s a basic indicator of engagement and largely depends on your subject line and sender name. A low open rate may suggest that your subject lines need improvement or that your emails aren’t reaching the primary inbox.

2. Click-Through Rate (CTR)

The click-through rate measures the percentage of recipients who clicked on links within the email. CTR helps gauge the effectiveness of your content, CTAs, and design. A higher CTR indicates that your content resonates with readers and encourages action.

3. Conversion Rate

Conversion rate is the percentage of recipients who completed the desired action after clicking on an email link (e.g., purchasing a product, signing up for an event). Tracking conversions can help you determine the ROI of your campaigns and understand which content drives conversions.

4. Bounce Rate

Bounce rate is the percentage of emails that were not successfully delivered to recipients’ inboxes. There are two types: “hard bounces” (due to invalid or non-existent email addresses) and “soft bounces” (temporary issues, like a full inbox). High bounce rates can negatively impact deliverability and sender reputation, so it’s crucial to clean your email list regularly.

5. Unsubscribe Rate

The unsubscribe rate indicates the percentage of recipients who opted out of future emails after receiving a particular campaign. A rising unsubscribe rate may signal that your content is not meeting audience expectations or that you’re emailing too frequently. Monitoring this metric helps you maintain a healthy list of engaged subscribers.

6. Spam Complaint Rate

Spam complaints are flagged when recipients mark your email as spam. High complaint rates harm deliverability and sender reputation. To minimize spam complaints, offer an easy-to-find unsubscribe option and ensure that your content aligns with subscriber expectations.

7. Email Read Time

Some email tracking tools provide insights into how long recipients spend reading your email. Understanding read time helps assess whether your content is engaging or too lengthy. A higher read time generally indicates more interest, while short read times suggest that readers may find the content irrelevant or uninteresting.

Improving Deliverability and Performance:

• Build and Maintain a Healthy Email List:

Focus on growing a list of engaged, interested subscribers and regularly clean the list to avoid invalid contacts.

• Use Double Opt-In:

Double opt-in requires subscribers to confirm their interest, ensuring only interested individuals are added to your list.

• Monitor Performance Metrics Regularly:

Review open rates, CTR, and spam complaints to identify trends and improve future campaigns.

• Test and Optimize:

Use A/B testing for subject lines, content, and design elements to see what resonates with your audience.
