# ListDefender

> ListDefender is an email list protection platform that automatically cleans email lists, blocks bots and fake signups, and manages subscriber engagement. It integrates directly with CRMs including Keap, HighLevel, and ActiveCampaign to protect sender reputation and improve email deliverability for small businesses.

## Overview

ListDefender is the all-in-one email deliverability tool designed specifically for small businesses. The platform addresses the critical challenges that small business marketers face: maintaining clean email lists, preventing bot signups, and ensuring emails reach real engaged subscribers.

The platform combines three core protection layers:
1. Automated email list cleaning through regular SmartScans
2. Real-time form protection via FormDefender to block bots and invalid submissions
3. Engagement management to identify and suppress unengaged contacts

ListDefender integrates seamlessly with popular CRM platforms including Keap, HighLevel, and ActiveCampaign. Integration takes under 60 seconds with no manual uploads or downloads required. All connections use secure API integrations with industry-standard encryption.

## Pricing

ListDefender starts at just $20/month, with pricing based on the size of your marketable email list. The platform only charges for marketable contacts (contacts that are opted in), not your entire database.

Pricing tiers scale based on contact count with transparent, simple pricing and no hidden fees. An interactive pricing calculator is available at https://listdefender.com/#pricing to calculate exact costs based on your list size.

### Agency Program

The Agency Program starts at $60/month and allows agencies to add unlimited client sub-accounts with full list cleaning and form protection for each client. This program is ideal for agencies managing multiple client email lists.

### Affiliate Program

ListDefender offers an Affiliate Program with 30% lifetime commissions for referring customers. More details available at https://listdefender.com/partners.

## Core Features

ListDefender automatically verifies and cleans email lists, removing invalid, disposable, and low-quality addresses so you only send to real subscribers who can actually receive your emails.

**How it works:**
- Plugs directly into your email marketing system
- Performs regular SmartScans automatically
- Catches bad or non-existent addresses before they cause problems
- Protects sender reputation and inbox placement without manual effort
- Every contact is automatically tagged in your CRM based on their status

**Validation tests performed:**

Most validation options are configurable to provide flexibility in how various scenarios are handled.

**Contact Tagging:**
ListDefender provides three primary tags:
- Green: Safe to email

- Red: Do not email

Additional optional tags are available. Users can suppress certain contacts from campaigns or prune contacts from their system based on these tags, giving complete control over list management.

### FormDefender (Form Protection)

FormDefender blocks bots, fake signups, and junk submissions in real-time before they ever hit your CRM. It ensures your list grows only with genuine subscribers who can actually buy from you.

- Validates that new contacts have been appropriately vetted before receiving emails
- Can quickly delete contacts that shouldn't have been created
- Included at no extra cost

**Form Compatibility:**
FormDefender works with most web forms regardless of form builder:
- Keap forms
- HighLevel forms
- ActiveCampaign forms
- WordPress forms
- Custom HTML forms
- Integration through lightweight JavaScript snippet

### Engagement Management

ListDefender tracks how subscribers interact with emails and identifies both unengaged contacts and those starting to go cold, allowing you to suppress inactive contacts and re-engage the rest.

**Features:**
- Auto-tag every contact based on opens, clicks, and activity
- Spot and suppress unengaged contacts before they hurt deliverability
- Focus efforts on subscribers most likely to open, click, and buy

## Sender Reputation Protection

Your sender reputation is directly impacted by:

ListDefender protects sender reputation by:
- Removing invalid email addresses before sending
- Blocking fake signups that would never engage
- Tracking engagement to focus on active subscribers
- Keeping deliverability high and emails landing in the inbox

## Blocked Submission Handling

When FormDefender blocks a bot or invalid submission, it prevents the contact from entering the CRM entirely. All blocked submissions are visible in the ListDefender dashboard with details about why they were blocked, providing full visibility and allowing review if needed.

For sophisticated bots that bypass standard controls, Enhanced Protection mode handles these situations and is included at no extra cost.

## Data Security

ListDefender takes data security seriously:
- All connections to CRMs use secure API integrations
- Industry-standard encryption
- Data is never shared or sold
- SOC 2 compliant security practices

Unless explicitly configured in FormDefender settings, ListDefender will not delete contacts from your CRM. Instead, it tags contacts based on validation status, giving you complete control to decide what to do with your list.

## Customer Testimonials

**Scott Richins, Technology Marketing Toolkit**
"Welp...I happened to notice some weird stuff going on with contact id's. We've spanned hundreds already this morning, which makes no sense. So I look at how many spam submissions have already been filtered today. Already 2k just this morning. Nearly 100k in the past 30 days. Holy crap. Thanks so much for building this tool!"

**Kaileen Sherk, Biddy Tarrot**
"ListDefender Saved Our Business! Our email deliverability plummeted and our business was slowly being choked out and no one could identify what was going on. ListDefender identified the issue immediately and stopped the bots, removed the bad accounts, and got us back on track. What ListDefender accomplished in hours, Klean13 and multiple tech agencies couldn't do at all. We won't run our business without it again."

**Mark Harbert**
"I do want to say, it is STAGGERING the amount of bots ListDefender is catching....lol. Look at this image with the sheer number and you can see the list of bot submissions. We are in the middle of a big promo and generating a lot of leads and WOW, just WOW!"

**Robersa Ephtimios, Essentrics**
"ListDefender has given us a clear & accurate view of the contacts in our CRM. It's helped protect our reputation by identifying bots and reducing spam complaints, keeping our deliverability strong and our lists healthy. Maintaining this level of visibility and control used to be nearly impossible; now I couldn't imagine operating without it."
