HubSpot Email Deliverability: Good or Bad? Our In-depth Analysis

HubSpot has earned its place as one of the most popular CRMs.

You can manage leads, run campaigns, automate follow-ups, and even write content with its AI tools, all from one dashboard.

But as your email volume grows, HubSpot email deliverability is something to look at, since the platform doesn’t focus on the technical side of sending.

Because while it’s excellent at organizing data and workflows, its email deliverability is a little different.

And that’s what we’ll cover in this guide: how HubSpot sends emails, what works, what doesn’t, and what that means for your HubSpot email deliverability.

‍

Key Takeaways

• HubSpot’s email deliverability is reliable for marketing emails and campaigns sent to existing or opted-in contacts, but not good for cold email deliverability
  
  
• It runs on shared sending infrastructure, so you don’t get control over IPs or backend settings.
  
  
• Domain authentication and a clean contact list can greatly improve inbox placement in HubSpot.
  
  
• HubSpot isn’t designed for cold email outreach or large-scale deliverability testing.
  
  
• If you need more control, pairing HubSpot with a dedicated infrastructure tool like Infraforge helps manage IPs, warmup, and reputation in the background.

How HubSpot Actually Sends Your Emails

Here’s what really happens when you send an email through HubSpot:

1. You create the email inside HubSpot’s Smart CRM or Marketing Hub.

All emails, whether they’re for marketing or sales, are written and managed directly inside HubSpot’s dashboard.

You can add templates, automate follow-ups, and track engagement, all in one place.

2. HubSpot processes and sends your email through its own system.

Once you hit send, HubSpot’s internal servers handle the delivery.

You don’t need to connect any external mail service or infrastructure; everything runs through HubSpot’s network automatically.

3. The email is tracked and synced with your CRM data.

HubSpot instantly logs the send, tracks opens and clicks, and connects all activity to your contact record.

That’s how it gives you a complete view of your communication history.

If you’re on a paid plan, you can also connect and authenticate your own domain, which gives your emails more credibility when they reach inbox providers.

HubSpot sends emails well to the contacts already saved in your CRM.

But if you want to email new people or do any kind of cold outreach, the system doesn’t give you much control over inbox placement, sender reputation, or domain health.

The Few Things HubSpot Gets Right About Email Deliverability

HubSpot might not be built for deep deliverability control, but it does a few things well that make everyday email sending easier and more reliable.

• Everything stays connected to your CRM.

Each email you send is instantly connected to the right contact and deal. You can see opens, clicks, and previous conversations in the same place.

• It gives you built-in tools to write and send smarter

HubSpot’s AI features, email templates, and tracking make your messages sound more natural and better timed, which helps them feel less like mass emails.

• It keeps your data clean and organized.

Because HubSpot keeps everything inside one system, your lists update in real time. That means fewer bounces, duplicates, or messy imports.

• Paid users can build more trust with authenticated domains

On paid plans, you can connect and verify your own domain. It removes HubSpot branding and gives your emails a more professional identity.

So even without technical control, HubSpot still offers a simple and organized setup for everyday email sending.

What Are the Most Common Issues With HubSpot Email Deliverability

HubSpot keeps email sending simple, but when it comes to inbox performance and control, there are a few clear limits to know about.

• There are no tools for technical deliverability.

HubSpot focuses on CRM and automation, not the infrastructure side of email delivery.

You can’t manage DNS records, warm up domains, or monitor sender reputation inside the platform.

• Free plans come with HubSpot branding

On the free version, every email carries HubSpot’s branding. It’s fine for basic outreach, but it can make your messages look generic or less personal.

• It’s not made for cold or high-volume outreach

HubSpot is designed for marketing to contacts who already know your brand.

Sending cold or bulk emails can affect your results and limit inbox placement.

• Even Higher plans doesn’t change the infrastructure

Upgrading gives you more features and automation, but your emails still use the same shared sending system.

So while usability improves, deliverability control stays the same.

It’s a great tool for managing engaged lists and marketing workflows, but not for users who want full control over inboxing and reputation for cold outreach.

5 Ways to Improve Email Deliverability in HubSpot

HubSpot might not give you full control over deliverability, but there are still a few smart things you can do within the platform to help your emails reach inboxes more consistently.

1. Authenticate your domain

• If you’re using a paid plan, connect and verify your domain.
  ‍
• This tells inbox providers that your emails are legitimate and removes HubSpot branding from your messages, which instantly looks more professional.

2. Keep your CRM contacts clean

• HubSpot makes it easy to manage and update contact records.
  ‍
• Regularly removing inactive or duplicate contacts and clean lists can lower the chances of email bounces and help build a stronger sender reputation.

3. Use HubSpot’s AI tools for better content

• Use the built-in AI writer and email templates to create natural, well-structured emails.
  ‍
• Personalized and relevant content performs better and is less likely to be flagged as promotional.

4. Track engagement closely

• Use HubSpot’s reporting dashboard to monitor open and click rates.
  ‍
•  If your numbers drop, adjust your messaging or timing before it affects your sender reputation.

5. Don’t overdo automation

• HubSpot makes automation easy, but sending too many emails too fast can reduce engagement.
  ‍
• Focus on consistency and timing instead of volume.

HubSpot may not offer technical control, but when you follow these steps, you give your emails a better chance to perform well within the system you already use.

Final Thoughts: Is HubSpot’s Deliverability Good or Bad?

HubSpot gets a lot right. It's easy to manage, good for running email campaigns, tracking contacts, and automating workflows.

And if you’re doing cold email or reaching people outside your CRM, there isn’t much flexibility to shape how those emails are delivered.

You don’t get control over IPs, DNS records, or domain reputation.

The good part is you don’t have to change how you use HubSpot.

You can keep your campaigns, automation, and CRM exactly the same.

You don’t have to move away from HubSpot; you just add the infrastructure layer it doesn’t have.

Infraforge handles the infrastructure: private IPs, authentication setup, warmup, and checking your domain health.
