The Complete Guide to Email Deliverability: Tips to Land in the Inbox Every Time

What is Email Deliverability and Why Does it Matter?

Email deliverability refers to the ability of your email to successfully reach your recipient’s inbox. It’s different from delivery, which simply means the email didn’t bounce. Deliverability is about avoiding spam filters, meeting authentication requirements, and building trust with email providers.

High email deliverability ensures:

• Increased Open Rates: Emails that land in the primary inbox are more likely to be opened.
• Improved Reputation: Consistently delivering emails builds a trustworthy sender reputation.
• Better ROI: A higher percentage of emails reaching inboxes means better chances of conversions.

Common Issues Affecting Email Deliverability

Before diving into the solutions, it’s important to understand the common obstacles businesses face:

1. Spam Filters: Misconfigured domains or spammy content can trigger filters.
2. Poor Domain Reputation: A bad reputation reduces the chances of inbox placement.
3. Lack of Email Authentication: Without SPF, DKIM, and DMARC, emails might be flagged as untrustworthy.
4. Low Engagement: Emails with poor open rates may be deprioritized by email providers.

Actionable Tips to Improve Email Deliverability

1. Authenticate Your Emails

Authentication is critical for building trust with email providers. Set up:

• SPF (Sender Policy Framework): Defines who can send emails on your domain’s behalf.
• DKIM (DomainKeys Identified Mail): Ensures email integrity by verifying it hasn’t been altered.
• DMARC (Domain-Based Message Authentication, Reporting, and Conformance): Aligns SPF and DKIM for maximum security.

SmarterOutbound offers automated SPF, DKIM, and DMARC setup, saving you time and ensuring proper configuration.

2. Monitor Your Sender Reputation

Your sender reputation determines how email providers view your domain. Regularly monitor:

• Bounce rates
• Complaint rates (spam reports)
• Blacklist status

SmarterOutbound’s real-time reputation monitoring tools can help you stay ahead of issues and protect your domain.

3. Build a Quality Email List

Avoid purchasing email lists or sending to outdated contacts. Instead:

• Use double opt-in to confirm email addresses.
• Regularly clean your list to remove inactive subscribers.

SmarterOutbound ensures only verified contacts are included in your campaigns, improving deliverability rates.

4. Optimize Your Email Content

The content of your emails plays a big role in deliverability. Follow these best practices:

• Avoid Spammy Words: Phrases like “Free,” “Win,” or “Act Now” can trigger spam filters.
• Keep It Short and Relevant: Long, irrelevant content is less likely to engage readers.
• Use a Plain Text Alternative: Include a plain-text version alongside your HTML emails.

5. Test Your Emails Before Sending

Tools like inbox testers can help you identify potential deliverability issues before launching a campaign. Look for:

• Missing headers
• Spam-triggering keywords
• Broken links or images

SmarterOutbound integrates deliverability testing directly into your campaign workflow.
