Hupspot email suspension guide

When you send marketing emails through Hubspot, your account is monitored to protect deliverability for all users. If performance drops or your settings conflict with email best practices, Hubspot can suspend marketing email sending to keep your reputation and recipients safe.

This guide explains the main suspension reasons, how to diagnose the issue, and the exact steps you can take to restore sending while improving long‑term results.

Why Hubspot suspends marketing email sending

Email providers and spam filters closely track how recipients react to your messages. To keep your emails landing in the inbox, Hubspot enforces quality standards. When these thresholds are exceeded, your portal can be restricted or fully suspended.

Typical triggers include:

High hard bounce rates
Excessive spam complaints
Low engagement and high unsubscribes
Configuration or compliance conflicts

Understanding which threshold you crossed is the first step to resolving a suspension.

Key metrics Hubspot monitors for suspensions

Several performance signals influence whether email sending remains enabled in Hubspot.

Hard bounce rates and invalid contacts

A hard bounce happens when an email cannot be delivered permanently, often because:

The address does not exist
The domain is invalid
The receiving server blocks delivery permanently

If a large share of your recent sends bounce, it suggests your list is not up to date or was collected without proper validation. To protect sender reputation, Hubspot can pause or stop sending until the issue is fixed.

Spam complaints and abuse reports

Spam complaints occur when recipients click “report spam” or mark your mail as junk. Many providers treat this as a strong negative signal. If complaint rates climb above industry norms, Hubspot may suspend email sending to prevent broader deliverability damage.

Common causes include:

Sending to contacts who never opted in
Unclear sender identity or misleading subject lines
Overly frequent, irrelevant, or aggressive campaigns

Low engagement and unsubscribes

Very low open or click rates, combined with elevated unsubscribe rates, can also flag risk. While a single weak campaign will not usually trigger suspension, repeated patterns make it likely that Hubspot will enforce stricter protection.

Types of Hubspot email suspensions

Not every restriction is permanent. Depending on the severity of the problem, Hubspot may apply different types of limits.

Temporary performance-based suspension

If a campaign exceeds thresholds for bounces or complaints, Hubspot may temporarily disable new marketing sends while allowing you to:

Audit and clean your lists
Update subscription types and consent records
Adjust content and frequency

Once the underlying problem is resolved and reviewed, sending can often be restored.

Permanent or account-level suspension

In severe or repeated cases, Hubspot may permanently restrict marketing email sending from your account. This usually occurs where there is clear risk to shared infrastructure, such as:

Consistent use of purchased or scraped lists
Ignoring prior warnings or remediation steps
Extremely high complaint or bounce rates over time

With this level of enforcement, you may need to work directly with support to understand options and next steps.

How to diagnose your Hubspot suspension

To start resolving any suspension, first gather data from within your portal.

Review email performance dashboards. Identify recent sends with unusually high bounce or complaint rates.
Check individual email details. Look at hard bounce categories, spam reports, and unsubscribes for affected sends.
Audit your contact sources. Confirm where contacts originated, how they opted in, and when they were last updated.
Verify domain and settings. Make sure DNS records, sending domains, and subscription settings follow Hubspot recommendations.

If your account displays a suspension or warning banner, follow any linked documentation, which typically points to the official help page at this Hubspot email suspension article.

How to fix a Hubspot email suspension

The quickest path to recovery is to address the exact trigger. Use the steps below as a structured checklist.

1. Clean and validate your contact lists

Start by improving list quality before asking for sending to be restored.

Remove all clearly invalid or role-based addresses (e.g., info@, sales@, support@ where not appropriate).
Segment by engagement and suppress contacts who have not opened emails in a long time.
Use a reputable email validation service to identify risky addresses before re‑sending.
Avoid uploading purchased, rented, or scraped lists; Hubspot policies prohibit these sources.

2. Confirm consent and subscription settings in Hubspot

Ensure that every contact you email has a clear and verifiable opt‑in.

Review forms and landing pages to confirm they explicitly request marketing consent.
Use double opt‑in where possible to create a strong audit trail.
Map contacts to the correct subscription type so you only send relevant content.
Make unsubscribe links visible and easy to use to avoid spam complaints.

3. Improve email content and sending practices

Content and frequency strongly affect whether recipients react positively or mark emails as spam.

Use accurate, non‑misleading subject lines and preview text.
Clearly identify your brand in the from name and email address.
Limit sending frequency, especially to new or low‑engagement segments.
Personalize content and segment audiences to improve relevance.
Test smaller segments first before rolling campaigns out to your full database.

4. Verify your technical setup

Strong technical configuration reinforces good list and content practices.

Authenticate your sending domain with SPF, DKIM, and, where recommended, DMARC.
Use a consistent from domain that matches your brand website.
Avoid using free, generic from addresses for business campaigns.

5. Work with Hubspot support when needed

If your portal is already suspended, you may need to contact support to request review. When you do, be prepared to provide:

A description of how contacts were acquired
Evidence of opt‑in or subscription management
Actions you have already taken: list cleaning, validation, and process changes
Plans to prevent future issues

A clear explanation and documented improvements increase the likelihood that Hubspot will consider restoring your sending ability.

Preventing future Hubspot suspensions

Once you have resolved the immediate issue, put ongoing processes in place to protect your sender reputation.

Regularly remove unengaged contacts after a defined period.
Monitor each send for bounces, complaints, and unsubscribes.
Standardize how you capture and store consent across forms and offline activities.
Train your team on acceptable list sources and email policies.

Consistently following these practices reduces the risk of crossing the thresholds that trigger Hubspot enforcement.
