7 Contact Lists You Need for Your Email Marketing

Written by Laura Tussi | Mar 5, 2025 7:04:06 PM

You might argue, but email marketing remains as a powerful tool for businesses to connect with their audience.

However, the effectiveness of these campaigns depends on how well you manage your contact lists. By organizing your contacts into distinct categories, you can ensure that your messaging is both relevant and engaging.

This increases engagement and improves deliverability by reducing spam complaints. With smart segmentation, marketers can personalize content for each audience, increasing conversions.

 

7 Must-Have Contact Lists for Every HubSpot Portal

1. Email Health Contact List (bounces, DOI, subscriptions)

A healthy email subscriber list forms the backbone of any successful email marketing strategy. This list includes everyone who has opted to receive communications from your business, often through newsletters.

It's crucial to maintain a clean subscriber list by employing double opt-in processes, especially in regions governed by GDPR regulations. This practice ensures that subscribers have explicitly agreed to receive your emails, which can significantly reduce bounce rates and complaints. Regularly updating your list to remove inactive or invalid emails helps maintain high deliverability and engagement rates.

Example of filters you can use for this list.

 

Exclusion lists are also essential for maintaining the health of your email marketing efforts. These lists typically include contacts you no longer wish to engage with, such as unsubscribed users, bouncebacks, and internal emails like those of employees or partners.

By excluding these contacts from your campaigns, you can prevent negative impacts on your sender reputation and deliverability. Additionally, regularly auditing these lists can help identify opportunities to either re-engage or permanently remove contacts, ensuring that your communications reach the most receptive audience.

2. All Contacts Created Contact List(for smart content)

Having a complete all-contacts list allows for more dynamic smart content that adapts to each life cycle stage.

With this, your content automatically personalizes based on whether someone is already a contact, helping you build stronger connections and engagement.

Example of an all contacts list.

 

3. Segmenting Contacts Based on Life Cycle Stages

Segmenting your contact lists based on life cycle stages is a sophisticated method for delivering tailored content. These stages can include leads, marketing qualified leads (MQLs), sales qualified leads (SQLs), and opportunities.

Example of a contact list segmenting all the MQLs.

By categorizing contacts in this manner, you can craft specific messages that resonate with each stage in the customer journey. This approach not only improves engagement but also moves prospects through the sales funnel more efficiently. 

 

4. Lead Status Contact List

Creating a lead status list helps you track where each contact is in the sales journey. If you're using that property in HubSpot, it becomes quite simple to filter them.

This allows for more targeted follow-ups, personalized messaging, and better alignment between marketing and sales teams.

 

5. Utilizing Lead Scoring for Behavioral Segmentation

Behavioral segmentation through lead scoring offers another layer of precision in your email marketing strategy. By assigning scores to leads based on their interactions with your brand, you can categorize them into cold, warm, or hot leads.

Example of a list using Thalox Engagement Score for segmenting contacts based on their predictive behaviour.

For instance, leads scoring between 0-49 might be considered cold, whereas those scoring above 70 could be classified as hot.

This segmentation allows marketers to tailor their communication strategies to the engagement level of each lead, optimizing the chances of conversion while avoiding wasted resources on leads that are unlikely to convert.

 

6. Developing Persona-Based Lists for Targeted Campaigns

Persona-based lists are a cornerstone of personalized marketing. By creating personas based on demographic and psychographic data, you can categorize contacts into groups that share similar characteristics or behaviors.

Example of a Persona contact list.

This enables you to craft highly targeted campaigns that speak directly to the interests and needs of each persona. When your messaging resonates with the recipient on a personal level, it greatly increases the likelihood of engagement and conversion.

Persona-based lists ensure that your marketing efforts are both efficient and effective, maximizing ROI.

 

7. Implementing Product Interest Lists for Enhanced Engagement

Finally, product interest lists allow you to target contacts based on their expressed interest in specific products or services. By tracking which products a contact has shown interest in, you can tailor your email content to highlight relevant offers, updates, or promotions.

Example of a list using Area of Interest property.

 

This targeted approach not only increases engagement rates but also drives conversions by delivering content that aligns with the contact's preferences. Maintaining and updating these lists regularly ensures that your communications remain relevant, thus fostering a more personal connection with your audience.

By employing these seven types of lists—healthy email subscriber lists, master exclusion lists, lifecycle stages, lead scoring, persona-based lists, and product interest lists—you can enhance targeting, personalization, and communication efficiency.

This comprehensive approach not only boosts engagement and conversion rates but also strengthens the overall relationship with your audience, paving the way for sustained success in your email marketing endeavors.
