Why segmentation matters

Getting more opens isn’t just about engagement - it’s key to staying out of spam. The more your emails get opened and clicked, the more they trust your sender reputation.

List Segmentation FAQs

MailBluster isn’t just about sending emails. It’s about giving you every tool to grow smarter, faster, and more efficiently.

What is a standard segment?

A Standard Segment is a dynamic list that automatically updates based on rules you set. For example, you can create a segment of contacts who "opened a specific campaign but did not click a link." The list changes in real-time as contacts meet (or no longer meet) the conditions.

What is an A/B testing segment?

An A/B Testing Segment is a special segment type used to split your audience for email experiments. You can create two or more randomized groups from a larger list to test different subject lines, content, or send times to see which performs best before sending to your entire list.

What is a static segment?

A Static Segment is a fixed list created at a specific point in time. Subscribers added remain in that group unless you manually update it. Perfect for sending one-time campaigns to a specific audience, like event attendees or past buyers.

Can I combine multiple conditions in a segment?

Yes! With MailBluster, you can mix conditions like campaign activity, ecommerce behavior, tags, and fields to build highly targeted lists that drive better results.

Is there a limit to how many segments I can create?

No, MailBluster supports unlimited segments so you can organize your audience as precisely as needed — whether you're running small-scale promotions or large enterprise campaigns.

Why should I use segmentation instead of sending emails to everyone?

Segmentation helps you send the right message to the right audience at the right time. This leads to higher open rates, more clicks, and fewer unsubscribes — ultimately improving your email deliverability and ROI.
