# Filtering leads and prospects in Mailerfind

In this article, we explain step by step, and without unnecessary technical jargon, how the **new lead/prospect filtering feature** in Mailerfind works.
The goal is very simple: **keep only the contacts you are truly interested in** and discard the rest.

## What is Mailerfind’s filtering system?

The filtering system allows you to **organize, clean, and refine** the leads you have already obtained from your Instagram analyses.

Thanks to these filters, you can for example:

* Keep only profiles that have an email address
* Search for accounts that mention specific words in their bio
* Filter by number of followers
* Detect business accounts
* Prepare lists ready to export, run email campaigns, or create audiences in Meta Ads

All of this without writing any code and in just a few clicks.

## 1. Select sources (analyses)

The first thing you need to do is **select where the data comes from**.

### What are sources?

Sources are the **Instagram, Twitter, or other platform analyses** that you have already run in Mailerfind.

You can:

* Select **a single analysis**
* Or select **multiple analyses at the same time**

### What happens if I select multiple analyses?

Very simple:

* Mailerfind **merges all leads** from the selected analyses
* If a person appears in more than one analysis, **they are not duplicated**
* The final result is always a **clean, unique list of contacts**
👉 In other words: you can combine data without worrying about duplicates.

## 2. Apply filters

Once the sources are selected, the important part begins: **filtering**.
Filters allow you to decide **which type of profile you want to include** and which ones you don’t.
You can combine as many filters as you like.

### Text filters
These filters search for specific words or text within the profile.

###### Biography

You can filter profiles whose bio **contains certain words or phrases**.

Examples:

* `coach`
* `influencer`
* `sales`
* `teacher`
* `I teach`
Ideal for finding profiles with clear intent or a specific niche.

###### Username

Allows you to filter by words within the **username**.

Example:
* usernames containing `coach`
* usernames containing `academy`

###### City

If the profile mentions a specific city, you can use it as a filter.

Example:
* Barcelona
* Madrid
* Valencia

Perfect for local businesses or geo-targeted campaigns.

### Numeric filters

###### Followers

Filter profiles based on the **number of followers**.

Examples:
* More than 1,000 followers
* Between 5,000 and 50,000 followers

###### Following

Filter by the number of accounts a profile follows.

This can help you identify:
* More active accounts
* Less saturated profiles

### Account type filters

###### Is it a business account?

Allows you to filter only:
* Business accounts
* Or exclude them and keep only personal accounts

###### Email type

You can filter by the detected email type:
* **B2B** → corporate emails (company, custom domain)
* **B2C** → personal emails (Gmail, Outlook, etc.)

### Filters by available data

These filters allow you to keep only profiles that contain certain information.

You can filter by:
* Has phone number
* Has email
* Has website

Very useful to ensure your list is **actionable**.

### Campaign filters

If you have launched email campaigns with Mailerfind, you can use these filters to track how your contacts have interacted with them. It's ideal for segmenting audiences based on their behavior and designing more precise follow-up strategies.

The available options are:

###### Rating
Filters leads based on the rating assigned to them within a campaign. Useful for prioritizing the most valuable contacts. 

###### Email sent in campaign 
Filters the contacts who have already been sent an email within a specific campaign. Perfect for avoiding duplicate sends or for specific follow-up.

###### Opened email in campaign 
Filters the contacts who opened the email from a campaign. Very useful for identifying leads with genuine interest and sending them a personalized follow-up message.

###### Clicked in campaign 
Filters the contacts who clicked on a link within the campaign email. These are the most engaged leads, ideal for a direct sales action or priority follow-up.

💡 Tip: combine the "Clicked in campaign" filter with the "Has email" filter to get a list of highly qualified leads ready for a second round of contact.

## 3. What can you do with a filtered list?

Once you have the list exactly the way you want it, you can use it in several ways.
