Is Hubspot Email Deliverability Good? Our 90-Day Usage Review

This is my honest HubSpot email deliverability review after 90 days.

I’ve sent over 10,000 emails using HubSpot.

At first, it worked great. Then the problems started—low open rates, spam issues, and dropped replies.

I tracked everything: inbox placement, bounce rates, and sender score.

And when it got worse, I switched.

If you're thinking about using HubSpot for cold email or marketing, read this.

I’ll show you what to expect before you risk your list or your money.

What Is Email Deliverability (And Why You Should Care)?

Just because your email says “sent” doesn’t mean it was seen.

It might land in the inbox.
‍
Or spam.
‍
Or nowhere at all.

That’s email deliverability.

It’s not about sending. It’s about landing where it counts.

Here’s what we tracked to know if deliverability was good or bad:

• Open rate (Did anyone even see it?)
  
  
• Bounce rate (Did it get rejected?)
  
  
• Inbox placement (Did it go to spam or promotions?)
  
  

If your emails aren’t landing in the right place, everything else falls apart.

This wasn’t some lazy spray-and-pray test. We did everything by the book.

Here’s the setup:

What HubSpot Says About Deliverability (vs What We Experienced)

HubSpot makes some bold claims about email deliverability.

We tested them. Here’s how each one held up:

The features sound great in the pitch deck, but they didn’t protect us when deliverability went south.

When HubSpot Email Does Work Well

Let’s be fair—HubSpot’s not bad at everything.

It actually works fine if:

• You’re sending to warm, opt-in lists
  
  
• Running internal sequences (like onboarding or lifecycle emails)
  
  
• Doing small-volume newsletters
  
  
• And using it as your all-in-one CRM/marketing suite
  
  

In that world? It holds up.

When HubSpot Email Falls Apart

But the second you try to scale cold outreach? Game over.

• Cold emails get flagged fast
  
  
• No inbox rotation, no way to manage multiple domains
  
  
• No built-in warm-up tools — so you start cold, and stay cold
  
  
• Shared IPs = shared risk (you get punished for what others do)

Dedicated IP vs Shared IP: What's the difference?

• Zero control over backend infrastructure
  
  

So, if your team is sending high-volume cold emails?

You’re flying a jet with no engine.

So We Switched to a Hubspot Alternative... But Not to Another CRM

This wasn’t a “let’s try a new CRM” problem.

Our CRM was fine.

Our deliverability sucked.

5 Ways to Improve Cold Email Deliverability Rates

We didn’t need a new HubSpot.

We needed emails that landed.

So we switched our infrastructure to Mailforge.

Is Mailforge a HubSpot Alternative? Here's the Honest Answer

Let’s not sugarcoat this.

✅ YES — Mailforge is perfect if you care about:

• Cold outreach that lands
  
  
• Inbox placement
  
  
• Domain + mailbox setup
  
  
• Deliverability at scale
  
  

❌ NO — if you’re looking for:

• CRM tools
  
  
• Marketing automation
  
  
• Lead nurturing workflows
  
  
• Reports and dashboards
  
  

Mailforge doesn’t pretend to be HubSpot.

It’s not a CRM. It’s a cold email machine.

And for what it’s built to do?

It’s damn good at it.

HubSpot vs Mailforge (For Email Deliverability Only)

Final Verdict — Is HubSpot Good for Email Deliverability?

✅ Yes — if you’re sending internal emails, warm newsletters, or using it as part of your CRM drip flows.

❌ No — if you’re doing cold outreach, need inbox control, or want to scale without getting burned.

For us, deliverability wasn’t a nice-to-have. It was the whole game.

And after 90 days inside HubSpot?

We knew one thing for sure:

We’d never use it for cold email again.
