The Importance of Email Deliverability

Email deliverability is the foundation of a successful email marketing campaign. It refers to the percentage of emails that reach your recipients' inboxes successfully. Achieving high deliverability ensures that your messages are not marked as spam, rejected, or sent to the recipients' junk folders, guaranteeing that your audience receives and engages with your content.

HubSpot recognizes the crucial role of email deliverability in successful marketing efforts and provides valuable tools and resources to help marketers optimize their campaigns for better results. By focusing on deliverability, you can increase open rates, click-through rates, and ultimately, your return on investment.

Tips to Improve HubSpot Email Deliverability

1. Build a Quality Contact List: Start with a clean and permission-based email list. Remove inactive and disengaged contacts regularly to maintain a healthy sender reputation.

2. Authenticate Your Domain: Implement SPF, DKIM, and DMARC authentication to prove to email service providers (ESPs) that your emails are legitimate and from a trusted source.

3. Personalize Your Emails: Create personalized and relevant content to engage your audience, leading to higher deliverability rates and improved engagement.

4. Monitor Engagement Metrics: Track open rates, click-through rates, and bounce rates to understand how your audience interacts with your emails and make necessary adjustments to improve deliverability.

5. Avoid Spam Trigger Words: Steer clear of spam trigger words that may raise red flags with ESPs and increase the likelihood of your emails being marked as spam.

6. Test and Optimize: Perform A/B testing on different elements of your emails, such as subject lines and call-to-action buttons, to identify what resonates best with your audience.

Avoiding Spam Filters with HubSpot

Spam filters are designed to protect users from unsolicited and potentially harmful emails. However, sometimes legitimate marketing emails may also get caught in these filters, leading to reduced deliverability rates. To avoid spam filters with HubSpot, follow these strategies:

1. Send Relevant Content: Ensure that your emails are relevant and tailored to your audience's interests and preferences.

2. Limit Use of Images: Avoid using too many images in your emails, as this may trigger spam filters.

3. Optimize HTML: Use clean and optimized HTML code in your emails to reduce the risk of being flagged as spam.

4. Provide Clear Unsubscribe Options: Make it easy for recipients to unsubscribe from your emails to comply with anti-spam regulations.

5. Regularly Monitor Deliverability: Keep a close eye on your email deliverability metrics and address any issues promptly.


As an expert in email marketing, optimizing your campaigns for excellent email deliverability is paramount. HubSpot provides robust tools and resources to help you achieve this goal. By implementing best practices, authenticating your domain, and avoiding spam filters, you can enhance your sender reputation, engage your audience, and drive meaningful results with HubSpot.
