How I Targeted Nonprofits Using Domain Extensions

Sometimes the best marketing strategies are hiding in plain sight. This week, I tried something simple that I haven’t seen many people talking about: targeting subscribers based on their email domain extensions.

The idea came to me when I noticed something obvious (that I’d somehow overlooked for months) – people who work at nonprofits almost always have .org email addresses. So I decided to create a highly targeted campaign just for them.

Here’s how I did it, what I learned, and why you should probably try this too.

What Makes This Work

At Email Love, we track over 150 nonprofit brands and have collected 2,000+ emails from organizations like Girls Who Code, RSPCA, and Friends of the Earth. We also have detailed trend reports showing send frequency, subject line patterns, ESP usage, and design trends specific to nonprofits.

This gave me something genuinely valuable to offer people working in this space – data and inspiration from their peers. I had a few hundred people in this segment – not huge, but definitely worth targeting with relevant content.

The Technical Setup (Easier Than You Think)

I use MailerLite, but this would work in pretty much any ESP:

Step 1: Create the Segment

Condition: Email address contains “.org”
Result: A few hundred highly targeted subscribers

Step 2: Build the Automation

Trigger: When a subscriber joins the .org segment
Wait: 4 days (gives them time to explore the site first)
Action: Send the targeted email

Step 3: Create the Email
I used our existing newsletter template in Figma (nothing completely bespoke needed) and included:

Personal thanks for their important work
Links to our nonprofit brands page
Nonprofit trend report highlights
A few inspirational email examples from well-known nonprofits

Using our Figma plugin, I could preview the email, export it as HTML, and copy the code directly into MailerLite. Total time investment: about 90 minutes.

Why I Think This Will Work

This email hits several psychological triggers:

Relevance: Content specifically for their industry
Appreciation: Acknowledging the important work nonprofits do
Social proof: Examples from recognizable organizations in their space
Shareability: The kind of resource people forward to colleagues

I’m expecting higher-than-average open and click-through rates because the content is so targeted. Plus, nonprofit marketers tend to be collaborative – I wouldn’t be surprised if this gets shared around their networks.

What’s Next

This was so quick and easy that I’m planning similar campaigns for other domain extensions:

.edu domains → Higher education email marketing insights
.ai or .io domains → SaaS/tech company email trends
.gov domains → Government/public sector communication examples
.co.uk/.com.au/.co.nz domains → Regional email marketing trends and compliance
Healthcare domains (.health, hospital domains) → Medical/healthcare email best practices
.museum domains → Cultural institution email strategies

The Bigger Picture

This strategy works because it’s based on a simple truth: people want content that’s relevant to their specific situation. By using something as basic as email domain extensions, you can create surprisingly targeted segments without needing complex data or expensive tools.

But here’s what makes domain-based targeting especially powerful – people with different email extensions often share common challenges, resources, and goals that go way beyond just their domain.

Nonprofit marketers (.org domains):

They’re usually working for causes they genuinely care about (mission-driven work hits different)
They’re almost always operating with tighter budgets than their corporate counterparts
Many are wearing multiple hats – the “marketing team” might be one person doing email, social, events, and donor relations
Design resources? Often nonexistent. They’re making do with Canva templates and hoping for the best
They want to send personalized, relevant emails but don’t have the tools, training, or time to figure it out

SaaS companies (.io domains):

These are mostly B2B SaaS companies with significant marketing budgets and resources
They want examples that showcase heavy personalization – pulling data from user dashboards, product usage, behavioral triggers
They usually have dedicated lifecycle marketing teams (not someone wearing five different hats)
Their focus is on customer education, engagement, and retention through sophisticated email sequences
They’re looking for advanced tactics: complex automations, API integrations, dynamic content based on user actions

Higher education (.edu domains):

Working within strict institutional guidelines and compliance requirements
Often targeting multiple audiences: prospective students, current students, alumni, faculty, parents
Budget constraints similar to nonprofits, but with different approval processes and stakeholders
Need to balance promotional content with educational value
Seasonal marketing cycles tied to academic calendars

Realistically, I can use this data to create more personalized automations based on what I can determine from their domain extension. My main goal is to get them coming back to see the latest inspiration for their type of business and checking out our trend report dashboards.

The point is: segmenting based on domain extension automatically tells you a ton about a subscriber or customer, and this is often completely overlooked. Most marketers are focused on complex behavioral data or expensive third-party demographics when they’re sitting on incredibly revealing information that’s right there in the email address.

Most ESPs have this segmentation capability built in.

Try This Yourself

Obviously, this tactic won’t work for all companies. If you’re a consumer brand selling directly to individuals with Gmail and Yahoo addresses, domain extension targeting might be less relevant for you. But for B2B companies, newsletters, agencies, and service-based businesses, looking at domain extensions could open up some interesting new segmentation, personalization, and automation opportunities.

Here’s your homework:

Look at your subscriber list and identify domain patterns
Check if you have content that would be specifically valuable to those groups
Create a simple segment and automation
Build one targeted email and see what happens

The whole process took me less than two hours, and I expect it to generate some of our highest engagement rates. Sometimes the best marketing tactics are the simplest ones.

Have you tried targeting by domain extension before? Let me know, I’d love to hear what worked (or didn’t work) for you.

Much love,
Andy
