How to Send Marketing Emails to More Contacts in HubSpot
Growing your email audience in HubSpot requires more than just adding new contacts. To send marketing emails to more people safely and reliably, you must manage bounces, unsubscribes, and permission settings carefully while following HubSpot email tools and policies.
This guide explains how HubSpot calculates your usable email audience, what limits your send size, and how to fix common issues so you can reach more qualified contacts.
How HubSpot Calculates Your Eligible Email Audience
HubSpot does not let you email every contact by default. Instead, it calculates an eligible audience based on several factors to protect deliverability and compliance.
Your eligible recipients are contacts who meet all of the following:
- Have a valid email address
- Are not bounced or globally bounced
- Are not unsubscribed from marketing email
- Have the correct subscription status (where applicable)
- Are not blocked by your own exclusion lists or filters
When you choose recipients for a marketing email, HubSpot shows how many contacts are eligible and how many are excluded, with reasons such as bounces or unsubscribes.
Key Reasons Contacts Cannot Receive HubSpot Emails
Before you can send campaigns to more contacts, you must understand why HubSpot excludes some addresses. The main reasons are bounces, opt-outs, and missing permission.
HubSpot bounces and global bounces
HubSpot automatically suppresses contacts with serious delivery issues. These are usually labeled as hard bounces or global bounces. Common causes include:
- Invalid or misspelled email addresses
- Nonexistent domains or mail servers
- Blocked sending due to spam or security filters
Once an address is globally bounced, HubSpot prevents further sends to protect your sender reputation.
Unsubscribes and preference changes in HubSpot
Contacts who unsubscribe or update their email preferences are removed from your eligible audience. In HubSpot, this can happen when:
- A contact clicks the unsubscribe or manage preferences link
- You manually opt a contact out in their record
- A GDPR-compliant opt-out is processed
HubSpot respects these opt-outs across all future marketing emails to that contact for the relevant subscription types.
Missing or withdrawn email permission
If you use subscriptions, HubSpot will only send marketing emails to contacts who are opted in to at least one relevant subscription type. Contacts with unknown or withdrawn consent cannot be included in those campaigns.
How to View Excluded Contacts in a HubSpot Email Send
Whenever you configure a marketing email, HubSpot shows a breakdown of who will and will not receive the message. To see this data:
- Open your marketing email in the HubSpot email tool.
- Go to the Send or Schedule step.
- Select your recipient lists and exclusion lists.
- Review the on-screen counts of eligible and ineligible contacts.
- Click through the details (where available) to see exclusion reasons such as bounces or unsubscribes.
This view helps you understand how many more contacts you could reach by resolving bounces or cleaning up invalid data in HubSpot.
Fixing Bounced Contacts in HubSpot
Not every bounced contact can be recovered, but some issues result from temporary or fixable problems. Follow these steps to address bounces.
Step 1: Identify bounced contacts in HubSpot
- Navigate to Contacts in your HubSpot account.
- Create a filtered view or list using email status properties, such as:
- Emails bounced
- Hard bounce reason
- Globally bounced
- Segment contacts by bounce reason to decide what to fix.
Step 2: Correct obvious data issues
Some bounces are caused by simple data errors. In HubSpot, review:
- Typos in email addresses (for example, gmial.com instead of gmail.com)
- Extra spaces or invalid characters
- Old or deactivated corporate email addresses
Update the contact’s email field with the correct address when you have verified it.
Step 3: Request bounce review when appropriate
If you believe a valid contact was incorrectly globally bounced, check HubSpot documentation about handling bounces at the official help center article. Some bounces may be eligible for review, while others are permanent and cannot be reversed.
Managing Unsubscribes and Preferences in HubSpot
Respecting unsubscribes is both a legal and platform requirement. You cannot override a legitimate opt-out in HubSpot, but you can reduce accidental or unnecessary unsubscribes.
Use clear subscription types
Set up meaningful subscription types in your HubSpot settings so contacts can opt out of specific categories rather than all marketing. Examples include:
- Newsletters
- Product updates
- Event invitations
- Promotional offers
When you send email, choose the correct subscription type so HubSpot applies the right permission logic.
Optimize the unsubscribe and preference links
Every marketing email sent from HubSpot should include legally required links. To improve list health:
- Ensure your Manage preferences page is easy to understand.
- Offer options to reduce frequency instead of full opt-out.
- Explain what each subscription type in HubSpot represents.
This approach can prevent unnecessary global unsubscribes and keep more contacts reachable.
Best Practices to Grow a Healthy HubSpot Email Audience
Growing your sendable list in HubSpot is about permission, quality, and maintenance.
Collect permission the right way
- Use double opt-in where supported in HubSpot for new subscribers.
- Capture consent on forms with clear checkboxes and descriptions.
- Avoid purchased lists, as they hurt deliverability and violate HubSpot and email policies.
Maintain your lists over time
- Regularly remove invalid or unengaged contacts using HubSpot list filters.
- Monitor bounce rates and spam complaint metrics.
- Reconfirm permission from inactive contacts before sending high-volume campaigns.
Improve deliverability step by step
- Authenticate your sending domain in HubSpot (SPF, DKIM, DMARC as applicable).
- Warm up new sending domains by starting with engaged contacts.
- Send relevant, segmented campaigns instead of broad blasts.
Consistently following these practices helps HubSpot classify more of your contacts as safe to email, increasing your effective audience size.
When You Cannot Email More Contacts in HubSpot
Some limits cannot be bypassed, even with clean data. In certain cases, HubSpot will permanently prevent emails to specific contacts, including:
- Contacts with permanent hard bounces that indicate the mailbox does not exist
- Contacts who have globally unsubscribed from all marketing
- Contacts who have marked your emails as spam via their provider
For these contacts, your only options are alternative channels such as ads, sales outreach, or support interactions outside HubSpot marketing email tools.
