What This Update Actually Is
HubSpot added custom font support to the drag-and-drop Marketing Email editor. If you've already uploaded fonts to your Brand Kit, those fonts now appear in every font selector dropdown inside the email editor.
Before this update, custom fonts lived in your Brand Kit but didn't flow into emails without manual CSS work. That meant marketers had two bad options: use the easy drag-and-drop editor and lose brand consistency, or hire a developer to inject fonts into a coded template.
Now those options collapse into one. The font you uploaded is the font you pick from the dropdown. No code. No ticket to engineering. No waiting.
Why HubSpot Shipped This
Brand consistency has always been a quiet source of friction in HubSpot portals. We see it constantly during portal audits: a company has a perfectly defined brand identity with a custom typeface, and then their emails go out in Arial because nobody had time to open a CSS file.
The external problem is simple: the drag-and-drop editor didn't respect Brand Kit fonts. The internal frustration runs deeper. Marketers feel like the tool is forcing them to compromise, and that erodes confidence in the whole platform.
HubSpot is also clearly doubling down on Brand Kit as the single source of truth for visual identity across hubs. Pulling fonts into email is a logical extension of that push. It's the same philosophy behind centralizing colors, logos, and voice in one place so humans don't have to remember or hunt.
How to Use It Step by Step
Start in your Brand Kit before you touch the email editor. The fonts won't appear in emails until they're added there first.
- Go to Content > Brand > Brand Overview in your HubSpot portal.
- Under Brand Kit > Fonts, click Add to open the font management panel.
- Click Add a custom font and upload your font file.
- Select a fallback font (Arial, Helvetica, Times New Roman, etc.) for email clients that don't support custom fonts. This step is critical, not optional.
- Navigate to Marketing > Email and click Create email. Choose Regular or Automated.
- In the drag-and-drop editor, open any text block's font selector. Your custom font now appears alongside the standard options.
One honest heads-up: Google Font support is listed as coming soon, so if your brand uses a Google Font, you'll need to upload the actual font file for now rather than referencing it by name.
What It Touches in Your HubSpot Strategy
This update lives in Marketing Hub, but its implications extend to any process that touches brand governance or email production.
Here's where it ripples:
- Eliminates the coded-template bottleneck that slows down marketing teams who rely on developers for brand-consistent emails, so you can ship faster without sacrificing identity.
- Makes Brand Kit the actual source of truth for email design, so updates to your font in Brand Kit flow into new emails without a manual re-configuration.
- Affects every email type built in the drag-and-drop editor, including Regular and Automated sends, which means your nurture sequences and one-off campaigns can finally match.
- Requires fallback font planning as a new governance task. If your team doesn't standardize the fallback font choice, you risk inconsistent experiences across email clients for the majority of your list.
- Surfaces a gap in email client support that honest teams must document. Gmail, Outlook, and Yahoo (which account for the majority of business inboxes) will display your fallback, not your custom font. Build that expectation into any brand standards doc you share with stakeholders.
Key Takeaway
Your fallback font is not an afterthought. Because Gmail, Outlook, and Yahoo don't support custom fonts, most of your recipients will see the fallback. Choose it as carefully as you chose your brand font.

Key Takeaway
Brand Kit is becoming HubSpot's design operating system. Every update that connects Brand Kit to a content tool (email, landing pages, ads) reduces the surface area where off-brand content can slip through.

Who Should Care Most
Not every update is equally urgent for every team. Here's who needs to act on this one first.
- Marketing managers and email owners who've been building emails in the drag-and-drop editor and accepting system fonts as the price of convenience. This update removes that trade-off entirely.
- Brand and design leads who've been frustrated watching email go out in the wrong typeface. Now you can lock the font in Brand Kit and trust the editor to surface it.
- HubSpot admins and portal owners at companies where Brand Kit is either incomplete or ignored. This is a good moment to get it right, because Brand Kit is clearly becoming more central to how HubSpot manages design across hubs.
- Growing companies on any tier since this ships to all hubs and tiers. There's no paywall here. If you have a HubSpot portal and a custom font, you can use this today.
The one profile that should pump the brakes slightly: teams whose email list skews heavily toward Gmail and Outlook users. The custom font will rarely render for those recipients. That doesn't mean skip the feature, but it does mean setting realistic expectations with leadership about what the visual experience will actually look like for most humans on the list.
George's Take
I've sat in way too many portal reviews where a company has a gorgeous brand identity and then their emails look like they were typed in a Google Doc circa 2012. The font is wrong, the spacing is off, and nobody knows how it got that way. What I love about this update is that it closes a gap that genuinely cost marketers time and credibility. But I want to be direct with you: the fallback font question is not a footnote. Most of your subscribers are reading in Gmail or Outlook. Your fallback is your email font for them. Choose it deliberately, document it in your brand standards, and don't let it be an afterthought just because the headline feature is exciting.
“Your fallback font isn't a backup plan. For most of your list, it's the plan. Pick it like it matters, because for Gmail and Outlook users, it's the only font they'll ever see.”
If you're investing in making your HubSpot emails look and perform better, it's also worth pairing this with a broader look at your Marketing Hub setup. Our guide on why Marketing Hub onboarding stalls at day 45 covers the patterns we see most often when teams start strong and then lose momentum, which is exactly when visual brand consistency tends to slip.

Frequently Asked Questions
Do custom fonts in HubSpot email work in Gmail and Outlook?
No. Gmail, Outlook, and Yahoo Mail don't support custom fonts. Recipients using those clients will see your chosen fallback font instead, such as Arial or Helvetica. Only email clients like Apple Mail support custom fonts. Plan your fallback font as carefully as your brand font, since most business inboxes run on Gmail or Outlook.
Where do I add custom fonts for HubSpot marketing emails?
Go to Content > Brand > Brand Overview in your portal. Under Brand Kit > Fonts, click Add and then Add a custom font to upload your font file. Once added to Brand Kit, your custom fonts appear automatically in the font selector dropdowns inside the drag-and-drop Marketing Email editor.
Does this HubSpot custom fonts feature require a paid tier?
No. The custom fonts in Marketing Email feature is available to all hubs and all tiers as part of the public beta launched April 14, 2026. You need a HubSpot portal with access to the drag-and-drop email editor and Brand Kit. No paid upgrade is required.
Will HubSpot support Google Fonts in marketing emails?
Not yet. As of April 2026, HubSpot lists Google Font support as coming soon. For now, you need to upload your font file directly to Brand Kit rather than referencing a Google Font by name. If your brand uses a Google Font, download the font file and upload it manually.
What happens if I don't set a fallback font for my custom font in HubSpot?
HubSpot requires you to choose a fallback font when you add a custom font to Brand Kit. If you skip this step, email clients that don't support custom fonts may default to a generic system font, which can break your email's visual hierarchy. Always choose a fallback that's close to your brand font's weight and style.
Does this update affect coded email templates in HubSpot?
No. This update specifically applies to the drag-and-drop Marketing Email editor. Coded templates already supported custom fonts through manual CSS. The new feature closes the gap for teams using the drag-and-drop editor who previously had to choose between ease of use and brand consistency.
