Have you ever heard the term “seed list” used? Well… we’ve been using this term a lot over here at Campaign Nucleus & we are excited to introduce seed list usability as one of our newest in-platform features.

So, firstly, what is a seed list? This is a list of emails that you have internal access to in order to be on the receiving end of your email sends.

Our email team has found that generally seed lists are not a great representation of inbox placement – this is because, after a few sends, the inbox will start to replicate personalized behavior rather than that of other inboxes with the same server. With that in mind, our team has found a lot of value in using email lists comprised of internal team members to help kickstart our email engagement with new or struggling domains/IPs.

Team members can be instructed to positively engage with these emails. In doing so, we can begin building up a good domain reputation from the very first day of sending so that we are able to find more success with deliverability and inbox placement.

Building highly targeted audiences has traditionally required complicated filters, layered segmentation rules, and technical expertise that can slow down campaign execution and audience management.

The new Nucleus AI Segment Builder changes that completely.

Designed to simplify audience creation, the AI Segment Builder allows organizations to create powerful CRM and email segments using simple natural language prompts instead of manual rule building and advanced filter logic.

Instead of spending time navigating complex targeting systems, users can simply describe the audience they want to reach — and Nucleus automatically generates the segmentation logic behind the scenes.

Create Audiences Using Natural Language

The AI Segment Builder makes advanced audience targeting dramatically easier by allowing teams to build segments conversationally.

Users can create audiences using prompts such as:

• “Donors in Florida who opened our last 3 emails”
• “Volunteers who attended an event in the last 12 months”
• “Inactive subscribers in key swing counties”

Nucleus instantly converts these requests into advanced segmentation logic, eliminating the need for manual filter building or technical setup.

Built Directly Into CRM and Email Workflows

Built directly into both the CRM and Amplify Email tools, the AI Segment Builder helps organizations create more targeted audiences faster while improving workflow efficiency across teams.

By integrating segmentation directly into existing campaign and communication workflows, organizations can move from audience creation to outreach much more quickly.

Key Capabilities

The AI Segment Builder includes a wide range of intelligent audience targeting features, including:

• Natural language audience creation
• AI-powered segment logic generation
• CRM and email module integration
• Advanced AND/OR targeting logic
• Smarter audience filtering without manual rule building
• Faster campaign setup and workflow execution
• Improved targeting precision for outreach and engagement

These capabilities help organizations build smarter campaigns while reducing the learning curve associated with advanced segmentation tools.

Accessible for Every Team

One of the biggest advantages of the AI Segment Builder is accessibility.

This release was designed to make advanced segmentation significantly more approachable for organizations of all sizes — from experienced data teams to users who may not feel comfortable building highly technical audience filters manually.

Instead of requiring deep technical knowledge, the platform allows teams to focus more on campaign strategy, messaging, and supporter engagement while Nucleus handles the complexity behind the scenes.

Powered by AI

Powered by advanced large language model technology, the AI Segment Builder represents another major step toward more intelligent, AI-assisted campaign and organization management inside Nucleus.

By simplifying audience creation and automating advanced segmentation logic, organizations can work faster, target more effectively, and execute campaigns with greater precision and efficiency.

The future of audience targeting isn’t about building more complicated filters — it’s about simply describing the audience you want and letting AI do the heavy lifting.

The campaigns winning right now aren't guessing — they're targeting. 

Goonies Never Say Die when it comes to Spam Traps

By Julia, Deliverability Expert

You’ve heard us mention “spam trap emails” – but do you know what that is?

Spam trap emails can catch even the least spammy of emails. This is because these email addresses are utilized specifically to locate senders who are not closely monitoring their recipient lists.

The thought process behind is that, should one of these “fake” emails enter your recipient list, it would be less likely that you are maintaining your recipient list so well that every email on it is a valid & confirmed subscriber.

Sending emails too many of these “recipients” could lead to many blocks that can be detrimental to your domain reputation and overall deliverability.

So how do you know which emails are spam traps? You don’t. They can be previously active but now expired emails, random emails made by servers for this purpose, and really anything in between. The servers use this method to help protect their users from receiving spam content but it surely adds an extra obstacle to those sending mass emails.

At the very least, you are now aware of what we mean when we say “spam traps” & at the very most, you’ll do your best to keep your email list as healthy as humanly possible.

AND LUCKY FOR YOU… we have a few in-platform tools to help you do just that.

Here are a few pointers to keep in mind regarding your recipient list:

ALWAYS turn on validations when importing new lists, especially large lists that may contain emails you are not personally familiar with…

Be sure to review recipient engagement and behavior – this is made easy with our Automation feature. Creating an engagement series for recipients who have not recently engaged with emails allows us to unsubscribe expired or uninterested recipients and their emails.

Respect the wishes of those who would like to be unsubscribed from your list. This means including visible unsubscribe links in all of our emails & reviewing responses for those who may have intended to unsubscribe. This is not only a legal requirement but will benefit you in the long-run. Angry recipients generally yield more spam complaints…
