How to Resend Emails to Bounced Contacts in HubSpot

When you send marketing emails in HubSpot, some messages may bounce and never reach the recipient. Understanding why contacts bounced and how to safely email them again is essential to protect your sender reputation and keep your account in good standing.

This guide walks through how bounced contacts work, when you can send to them again, and the exact steps to review, fix, and request unbounces inside your account.

How HubSpot Handles Bounced Contacts

Every marketing email you send generates delivery events. If a receiving mail server rejects an email, HubSpot records a bounce for that contact and email address. This protects your account and helps you avoid deliverability issues.

There are two key concepts to know:

• Contact-level bounces – Applied to the email address in the CRM when a bounce meets HubSpot’s criteria for permanent or repeated failure.
• Send-level bounces – Logged per email send for reporting, even if the contact is not fully blocked from future sends.

Only certain types of bounces completely prevent you from sending future marketing emails to that contact from HubSpot.

Types of Bounces in HubSpot

Before trying to resend to bounced contacts, confirm what type of bounce you are dealing with. In HubSpot, bounces are generally grouped into:

• Hard bounces – Permanent failures, such as an invalid or non-existent address.
• Soft bounces – Temporary issues, like a full inbox or a momentary server problem.
• Suspension-related bounces – Occur when sending is paused from your HubSpot account for safety or compliance reasons.

Contacts with permanent hard bounces are automatically excluded from future marketing sends to safeguard your domain reputation.

When You Can Email Bounced Contacts Again in HubSpot

You can only resend marketing emails to bounced contacts in HubSpot under specific circumstances. Generally, this is possible when the bounce was due to a temporary issue or a mistake, not a truly invalid address.

Typical scenarios where resending may be allowed include:

• The contact’s mail server was temporarily unavailable.
• The recipient’s inbox was full but is now cleared.
• The contact changed email providers and shared a new, valid address.
• There was a configuration issue on the recipient’s domain that has since been fixed.

If HubSpot has permanently bounced a contact’s email (for example, because the address does not exist), you should not attempt to send to that address again.

How to Review Bounced Contacts in HubSpot

To decide whether you can follow up with previously bounced contacts, you first need to review their bounce details in HubSpot.

Step 1: Open Your Email Performance Dashboard

1. Log in to your account and navigate to Marketing > Email.
2. Select the sent email you want to analyze.
3. Go to the Recipients tab and filter by Bounced.

This view shows which contacts bounced and the related status for that send.

Step 2: Check Individual Contact Records in HubSpot

1. Click a bounced contact from the recipients list.
2. On the contact record, locate the subscription and email health information.
3. Look for properties such as bounce reasons and whether the contact is permanently bounced for that email address.

These details help you determine whether a contact might be eligible for unbouncing.

Understanding Bounce Reasons in HubSpot

HubSpot stores an explanation for each bounce event. Reviewing this reason is critical before you resend anything.

Common bounce categories include:

• Mailbox full – The user’s inbox storage limit was exceeded.
• Server unavailable – The destination mail server was down or temporarily rejecting messages.
• Content or security filter – The recipient’s system flagged the message based on security or content rules.
• Unknown user – The email address does not exist on the recipient’s server (a true hard bounce).

If the reason indicates a temporary server or mailbox problem, you may be able to send again once the underlying issue is resolved. If it shows the address is invalid, you should not continue using that address in HubSpot.

How to Fix Issues Before Resending from HubSpot

Before you ask to unbounce or resend emails from HubSpot, make sure you have corrected any issues that caused the bounce.

Confirm the Email Address Is Correct

• Double-check spelling and formatting for typos.
• Verify the domain (for example, @example.com vs @example.co).
• Ask the contact to confirm their best email address and update the CRM record if needed.

Verify Recipient Server or Mailbox Problems

• If the bounce reason points to a full mailbox or server issue, confirm with the contact or their IT team that the problem is fixed.
• Request that they add your from-address and sending domain to their allowlist.

Improve Email Content and Sending Practices in HubSpot

• Use clear subject lines and reputable content.
• Avoid spam-triggering patterns and low-quality lists.
• Send only to opted-in, engaged contacts from your HubSpot database.

These steps help reduce future bounce risk when you send campaigns from your account.

How to Request an Unbounce in HubSpot

If you believe a bounced contact should be eligible to receive marketing emails again, you may be able to request an unbounce from HubSpot support.

Requirements Before Requesting an Unbounce

• You have verified the email address is valid and active.
• The contact wants to receive your communications.
• The root cause of the bounce (server, mailbox, configuration) has been fixed.
• You understand that HubSpot may deny the request if it risks your overall deliverability.

Submitting an Unbounce Request

The exact interface for unbouncing can change, so always follow the latest instructions in the official documentation. You can access the current guidance directly in the HubSpot knowledge base at this support article about resending to bounced contacts.

Typically, the process involves:

1. Collecting the email addresses and evidence that the issue is fixed.
2. Contacting support through your HubSpot portal.
3. Waiting for confirmation that the addresses have been reviewed and, if approved, unbounced.

Once an address is successfully unbounced, you can again include that contact in future marketing emails, while still following all compliance and permission guidelines.

Best Practices for Sending to Previously Bounced Contacts in HubSpot

Even after an unbounce is approved, you should be cautious when re-engaging these recipients from HubSpot to avoid another bounce or complaint.

Send a Targeted Re-Engagement Email

• Start with a single, clearly worded message.
• Explain why they are receiving the email and how they can manage preferences.
• Avoid heavy imagery or attachments that might trigger filters.

Monitor Performance in HubSpot Reports

• Track bounce rates, opens, and clicks specifically on this group.
• Immediately remove any addresses that bounce again for permanent reasons.
• Use HubSpot’s analytics dashboards to compare these contacts against your typical performance levels.

Maintaining Healthy Email Lists in HubSpot

Preventing bounces is more efficient than trying to fix them later. Use your HubSpot tools to keep lists clean and up to date.

• Regularly remove unengaged contacts who have not opened emails in a long time.
• Use clear opt-in forms and double opt-in where appropriate.
• Keep your contact properties and email addresses current.
• Leverage lifecycle stages and segmentation to send only relevant messages.

Healthy lists and careful sending behavior greatly reduce the number of bounces your HubSpot account will generate over time.
