When it comes to email marketing, deliverability is key. You can create the best email campaigns, but if they don’t reach your recipients’ inboxes, it’s all for nothing.
At EmailTooltester, we’ve had our eye on HubSpot's email deliverability for a while, and today, we’re updating our insights to reflect the most current details on their email deliverability features. As you may have noticed that we no longer conduct bi-annual deliverability tests, but we have recently updated our approach to assessing email marketing platforms.
Rather than relying on our previous seedlist testing methodology, we are now shifting our attention to the features and tools platforms offer to improve deliverability. And if you’re considering HubSpot, you’ll be happy to know that they do indeed provide solid email deliverability features to help you improve your email performance.
Let's take a closer look…

1. Authentication Compliance
HubSpot supports SPF, DKIM, and DMARC for email authentication. While it’s not strictly enforced, you are required to connect your email sending domain to HubSpot and set up DKIM to use your own domain as the “From” address.
Authentication Wizard: HubSpot provides an easy-to-follow in-app authentication wizard to guide users through setting up SPF, DKIM, and DMARC. You can find helpful resources to ensure you’re compliant, making the setup process smooth and straightforward.
2. Spam Complaint Handling
HubSpot automatically suppresses bounces, unsubscribes, and spam complaints, which helps protect your reputation as a sender.
They also offer insights into overall spam complaints for individual emails, though they don’t provide detailed FBL data feedback on individual recipients marking an email as spam.
3. Dedicated Deliverability Support
HubSpot provides access to a deliverability support team through email and chat for paid plans. Enterprise customers get the added benefit of phone support, which can be especially helpful for addressing more complex deliverability concerns.
Deliverability Dashboard: HubSpot also provides an email health dashboard and a health score (out of 10) that allows you to monitor your sending performance and reputation.

4. List Hygiene
HubSpot doesn’t offer built-in list cleaning as part of its core features, but they do integrate with third-party services like Kickbox and NeverBounce for real-time and bulk email verification.
They also prohibit the use of purchased or rented lists, aligning with best practices to maintain high deliverability standards.
5. IP Reputation & Warmup Support
HubSpot offers guidance and support for IP warmup. For customers who purchase dedicated IP addresses, HubSpot initiates an automated 40-day warm-up process to help build a sender reputation with email providers.
They recommend gradually increasing email volume when sending from a new domain or ESP, ensuring mailbox providers recognize your new domain and email traffic as legitimate.
Why HubSpot is a Reliable Choice for Email Deliverability
HubSpot ticks nearly all the boxes when it comes to email deliverability. From helpful authentication support to clear guidelines for maintaining list hygiene and IP reputation, HubSpot offers essential tools to ensure that your emails have the best chance of landing in your recipients' inboxes.
Although HubSpot doesn't integrate directly with Google Postmaster Tools and lacks a built-in list cleaning tool, it provides access to helpful third-party integrations and offers proactive deliverability support.
For users with higher deliverability needs, HubSpot’s Enterprise plans come with phone support and additional features, including dedicated IP warmup guidance. Their deliverability health dashboard is a powerful tool for monitoring your performance and ensuring that your emails stay on track.
Final Thoughts: Hubspot Deliverability
In conclusion, HubSpot offers a comprehensive set of deliverability features that will help most businesses maintain high inbox placement rates. We believe that HubSpot’s approach to authentication, spam complaint handling, deliverability support, and last but certainly not least, the deliverability dashboard, makes it a solid option for marketers looking to ensure reliable email deliverability.
