How to Improve Email Deliverability: A Practical Guide for Better Inbox Placement
April 18, 2025 | Bhumika
Email marketing is still one of the most powerful tools for business growth. But no matter how compelling your message is, if your emails land in the spam folder, your campaign fails before it even begins. Improving your email deliverability is essential to ensuring your emails actually reach your audience’s inbox.
Here’s a practical guide to help you get there:
- Warm Up Your Email Domain
If you're starting with a new domain or haven't sent emails in a while, gradually increase your sending volume. This builds a positive sender reputation and reduces the chances of being flagged as spam.
- Authenticate Your Emails
Use essential email authentication protocols:
SPF (Sender Policy Framework)
DKIM (DomainKeys Identified Mail)
DMARC (Domain-based Message Authentication Reporting and Conformance)
These help email providers verify that your messages are legitimate and not spoofed.
- Use a Clean Contact List
Avoid using purchased or outdated lists. Focus on verified contacts who have opted in. Emailing people who didn’t ask to hear from you is one of the fastest ways to get marked as spam.
- Verify Your Email Addresses
Use tools to remove invalid or fake emails from your list. High bounce rates can severely damage your sender reputation.
- Personalize and Segment
Segment your audience and send relevant, personalized content. Sending the same email to your entire list can hurt engagement, which in turn affects deliverability.
- Monitor Engagement Metrics
Track open rates, clicks, bounces, and spam complaints. If you notice low engagement, test and adjust your subject lines, content, and sending times.
- Avoid Spam Triggers
Stay away from spammy language like “Buy now,” “100% free,” or using all caps and too many exclamation marks. Keep your design simple and mobile-friendly.
- Let People Unsubscribe Easily
Making it hard to unsubscribe frustrates users and increases spam complaints. A visible unsubscribe link is not just a good practice - it’s a must.
Improving email deliverability isn’t just a technical challenge - it’s a strategic move. By keeping your list clean, sending quality content, and maintaining your sender reputation, you set your campaigns up for success.
