How to Set Up Double Opt-In in Hubspot

Setting up double opt-in in Hubspot helps you collect high-quality email subscribers, protect your sender reputation, and stay compliant with email marketing laws. This guide walks you through exactly how to enable and configure double opt-in step by step.

What Is Double Opt-In in Hubspot?

Double opt-in is a subscription process where contacts confirm their email address after filling out a form. Instead of being immediately added as fully subscribed, they receive a confirmation email and must click a link to verify that they want to hear from you.

In Hubspot, double opt-in adds an extra confirmation step that helps you:

Reduce fake or mistyped email addresses.
Protect email deliverability by lowering bounce rates.
Build a cleaner, more engaged mailing list.
Comply with regulations in strict regions.

Before You Configure Hubspot Double Opt-In

Before turning on double opt-in, make sure your account and settings meet these basic requirements.

Hubspot subscription types and settings

Double opt-in works with email subscription types. You must have at least one marketing email subscription type set up.

Open your marketing email subscription types.
Confirm that each email you plan to send is associated with the correct subscription type.
Ensure you have a clear description of what contacts are signing up for.

Verify your email settings in Hubspot

To send confirmation emails reliably, check these elements in your account:

Your from address and reply-to address are properly configured.
Your email sending domain is connected and authenticated.
You can send standard marketing emails without errors.

Once this basic email setup is in place, you are ready to configure double opt-in in Hubspot.

How to Enable Double Opt-In in Hubspot

Follow these steps to turn on double opt-in and customize the confirmation flow.

Step 1: Open the double opt-in settings in Hubspot

Sign in to your Hubspot account.
Navigate to your main settings area.
In the left sidebar, go to your email or marketing email configuration section.
Look for the option related to subscriptions and double opt-in.

The double opt-in panel contains all options for enabling and managing the confirmation process.

Step 2: Turn on double opt-in

Within the double opt-in section, you can enable the feature for your account.

Locate the toggle or checkbox to activate double opt-in.
Turn the setting on to require confirmation for new contacts from selected sources.
Save your changes so Hubspot can apply the new behavior to incoming form submissions.

Once enabled, new contacts who meet your criteria will receive a confirmation email instead of being fully opted in immediately.

Step 3: Select which contacts must confirm

Hubspot lets you choose where double opt-in applies so you can control which new contacts must confirm their email.

Common options include:

All new contacts created by forms.
Contacts who submit specific forms only.
Contacts created via non-import methods.

Review your forms and decide where confirmation is required. For example, you might only enforce double opt-in on public website forms while excluding internal or private forms.

Customize Your Hubspot Double Opt-In Email

The confirmation email is a crucial part of the double opt-in experience. In Hubspot you can adjust its content, branding, and target subscription type.

Choose the subscription type for confirmation

First, decide which email subscription type the confirmation applies to. This determines what kind of email content the subscriber is agreeing to receive.

Select the primary subscription type you want confirmed.
Ensure the description clearly explains what subscribers will get.
Align this with the promises you make on your forms and landing pages.

Edit the confirmation email content in Hubspot

Next, customize the message that contacts will see when they receive the double opt-in email.

Open the double opt-in configuration email editor.
Edit the subject line to clearly indicate that confirmation is required.
Update the body copy to explain why they are receiving this email.
Include a strong call-to-action that tells them to click the confirmation link.

Keep the email short, clear, and aligned with your brand. Make sure the confirmation link is prominent and easy to click.

Adjust design and branding

Inside Hubspot you can typically adjust core elements so the confirmation email matches the rest of your brand communications:

Logo and header image.
Colors and typography within the template.
Footer details, including address and legal information.

Confirm that your legal footer, company name, and contact details appear correctly to build trust with new subscribers.

Configure the Hubspot Confirmation Follow-Up Experience

After a contact clicks the link in the double opt-in email, they should reach a clear confirmation page.

Choose or customize the confirmation page

In Hubspot you can either use a default system page or a custom page for confirmed subscribers.

Select a default confirmation page provided by the platform, or
Set a custom thank-you or welcome page you created in your site or landing page tools.

On this page you can:

Thank the subscriber for confirming.
Remind them what they will receive and how often.
Offer a quick next step, such as downloading a resource or visiting a key page.

Understand contact status after confirmation

When the subscriber clicks the confirmation link:

Their subscription status is updated to reflect consent for the relevant subscription type.
They can now receive marketing emails associated with that subscription.
They appear as confirmed contacts in your Hubspot email tools.

If a contact never confirms, they may remain in a pending or non-subscribed state, depending on your configuration.

Testing Your Hubspot Double Opt-In Flow

Before rolling out double opt-in to all traffic, test the entire experience end-to-end.

Submit one of your live forms with a test email address.
Check your inbox to ensure the confirmation email arrives quickly.
Verify that the subject line and body text display as expected.
Click the confirmation link and confirm that you reach the correct confirmation page.
Review the test contact record in Hubspot to ensure the subscription status is updated.

Run tests for each key form or scenario where double opt-in is enabled so you can catch issues early.
