Improve Email Metrics with HubSpot: Sunset Policy Guide

Managing inactive subscribers in HubSpot is essential if you want to protect deliverability, improve engagement metrics, and keep your CRM clean. A structured email sunset policy helps you decide when and how to stop mailing disengaged contacts, without losing valuable relationships.

This guide walks through how to design and implement a practical sunset framework based on the approach described in HubSpot’s own best-practices article, adapted into a clear, actionable how-to.

What Is an Email Sunset Policy in HubSpot?

An email sunset policy is a set of rules that define when a contact becomes unengaged and what steps you will take before finally stopping marketing emails to that person.

In a HubSpot context, a strong policy typically:

Uses clear behavioral criteria (opens, clicks, bounces, complaints).
Applies different rules to different types of email programs.
Includes re-engagement campaigns before suppression.
Relies on lifecycle stages and lists to automate decisions.

Why You Need a HubSpot Sunset Strategy

Sending repeated emails to people who never engage can hurt you in multiple ways.

A solid HubSpot sunset strategy helps you:

Protect sender reputation and inbox placement.
Improve open and click-through rates.
Prevent spam complaints and hard bounces.
Keep database size and costs under control.
Get cleaner reporting on what content really works.

Instead of relying on global, one-size-fits-all settings, the goal is to design policy by email type and by how contacts experience your brand.

Step 1: Map Your HubSpot Email Types

Start by mapping the core email categories you send from HubSpot. Different categories should have different sunset rules because expectations and engagement patterns vary.

Typical categories include:

Marketing newsletters and updates – scheduled, recurring mailings.
Product or feature announcements – occasional, higher-intent content.
Event and webinar promotions – time-bound, often with reminders.
Onboarding or educational series – nurture programs, often automated.
Promotional offers – discounts, trials, or sales driven content.

Document each category and note:

Audience (prospects, customers, partners).
Frequency (weekly, monthly, ad hoc).
Primary goal (clicks, sign-ups, purchases, usage).

Step 2: Define Engagement in HubSpot

Next, decide what counts as meaningful engagement for each email category in HubSpot.

Common engagement signals:

Opened at least one email in a timeframe.
Clicked at least one link.
Registered for an event or webinar.
Took a product action (e.g., logged in, upgraded).

You can use contact properties and email performance data to define engagement windows such as:

Highly engaged: Opened or clicked in last 30 days.
Warm: Any engagement in last 60–90 days.
Unengaged: No engagement in last 90–120 days.

Use these thresholds as the basis of your future HubSpot lists and workflows.

Step 3: Set HubSpot Sunset Thresholds by Email Type

Now translate engagement rules into specific sunset thresholds for each email category in HubSpot.

Examples:

Newsletters: If a subscriber has received 8–12 consecutive sends without an open or click, treat them as unengaged for newsletters.
Event invitations: If a contact never registers or clicks after 3–4 invitations in a season or quarter, move them into an event-unengaged segment.
Onboarding: If a user stops opening onboarding emails for 30–45 days, pause or stop the series.

Document these thresholds clearly so you can implement matching rules in HubSpot lists and automations.

Step 4: Build Key HubSpot Lists

Lists are the backbone of a strong sunset framework. In HubSpot, use a combination of active lists to track engagement status by category.

Core lists to create:

Engaged marketing contacts – meets open/click criteria within your chosen window.
At-risk contacts – are nearing your unengaged threshold (for example, 6 newsletters with no interaction).
Unengaged contacts – have passed your threshold (for example, 12 sends, no opens, no clicks).
Suppression lists – contacts who should no longer receive certain categories of email.

Combine rules such as:

Number of emails received in a series.
Lack of opens and clicks.
Lifecycle stage or customer status.
Opt-out or spam-complaint history.

Step 5: Design Your HubSpot Re-Engagement Journey

Before completely suppressing unengaged contacts, offer a final chance to stay subscribed. Build a short re-engagement flow directly in HubSpot.

Key elements of a HubSpot re-engagement campaign

Attention-grabbing subject lines – highlight value or ask if they still want to hear from you.
Clear preference options – link to a subscription center so they can change frequency or topics.
Strong call-to-action – click to confirm they wish to stay subscribed.
Deadline – inform them that you will reduce or stop emails if they do not respond.

Implement this with a workflow that:

Enrolls contacts when they enter your unengaged list.
Sends 1–3 re-engagement emails over a defined timeframe.
Removes contacts from unengaged lists if they open, click, or update preferences.
Adds non-responders to suppression lists for that email category.

Step 6: Automate HubSpot Suppression Rules

After the re-engagement window closes, suppression should happen automatically. In HubSpot, you can layer suppression in several places.

Apply HubSpot suppression at the campaign level

Exclude unengaged or suppression lists from sends.
Exclude contacts with high bounce or complaint rates.
Exclude irrelevant lifecycle stages (for example, closed-lost deals from customer-only mailings).

Use workflows to maintain suppression

Automatically add new unengaged contacts to suppression lists.
Remove contacts from suppression lists if they later re-engage via another channel.
Update custom properties that track engagement status by category.

This keeps your HubSpot environment clean without manual list edits.

Step 7: Monitor and Refine in HubSpot Reporting

A sunset policy is not static. Use HubSpot reports and dashboards to review performance regularly and adjust thresholds.

Important metrics to watch:

Open and click-through rates by email type.
Spam complaint and hard bounce rates.
Growth and shrinkage of engaged versus unengaged lists.
Re-engagement campaign response rates.

If you see deliverability problems or falling engagement, tighten your windows. If engagement is strong and complaints are low, you may be able to extend your thresholds slightly.

Best Practices for a Sustainable HubSpot Policy

To keep your sunset framework effective over time, follow these best practices inside HubSpot:

Align with lifecycle stages – treat leads, opportunities, and customers differently.
Respect local regulations – honor regional consent rules and do not rely solely on engagement behavior.
Centralize documentation – maintain a simple reference that describes your lists, workflows, and thresholds.
Involve stakeholders – sales, success, and marketing should all understand how and why contacts are suppressed.

Regularly audit forms, imports, and integrations to ensure they do not override your suppression logic or re-enroll suppressed contacts in marketing sequences.

Next Steps Beyond HubSpot

Once your sunset policy is active, look for optimization opportunities across your broader marketing stack. Your email data can inform segmentation, website personalization, and paid audiences.
