Maximizing Email Marketing Success: A Comprehensive guide to improve Deliverability

Email remains a cornerstone of the marketing world due to its unrivaled ability to establish direct contact with potential customers—provided your emails make it to the inbox! That’s where the concept of email deliverability enters the fray.

Understanding Email Deliverability

What is Email Deliverability?

Email deliverability, simply put, is the ability of an email to successfully land in the recipient’s inbox, rather than in the spam folder or being blocked entirely. Its relevance in email marketing cannot be overstated, as only delivered emails can be opened, read, and acted upon.

Factors Impacting Email Deliverability

Several factors can influence your email deliverability:

  1. IP Reputation: The reputation of the IP address sending the email. If many emails from this IP were marked as spam in the past, future emails are more likely to land in the spam folder.
  2. Quality of Content: Emails with poor quality content, or content containing spam-like characteristics, can trigger spam filters.
  3. Bounce Rate: This refers to the number of undelivered/bounced emails. A higher bounce rate can tarnish your sender reputation.

Consequences of Poor Email Deliverability

Highly reputed brands like ‘Brand X’ have suffered a significant dip in their return on investments for their email campaigns due to poor email deliverability. Low engagement rates, loss of reputation, and missed business opportunities can be traced back to this issue.

Strategies to Boost Email Deliverability

Crafting Compelling Subject Lines

The subject line of your email is your first point of contact with the recipient—it needs to be engaging. Stick to concise and enticing language that clearly communicates the email’s purpose. For example, instead of “October newsletter”, try “Your exclusive October update!”

Avoiding Spam Trigger Words

Common spam trigger words like “free,” “guarantee,” “risk-free,” “urgent,” among others, should ideally be avoided.

The Risks of Purchased Email Lists

Purchasing email lists may seem tempting, but it’s a route strewn with risks. These emails can have high bounce rates, which harm your sender reputation and negatively impact your email deliverability.

Experimenting With Send Times

Finding the perfect send time when your audience is most likely to engage with your email is crucial. Try different schedule times, monitor performance, and iterate.

Regular Email List Cleaning

Maintaining your email list hygiene is crucial—occasionally remove inactive subscribers or invalid email addresses to boost your overall email engagement and deliverability.

Several tools can aid in keeping your email deliverability rates optimal:

  1. MX Toolbox: Assesses your domain’s health and offers ways to improve deliverability.
  2. Sender Score: Provides reputation scores that can predict deliverability success.
  3. Mail-Tester: Tests the spamminess of your emails to identify possible improvements
