Keep ActiveCampaign clean. Merge duplicate contacts easily and stop new ones with LinkActive’s verified LinkedIn integration.
Published on October 21, 2025
Duplicate contacts are a silent drain on your sales productivity. They clutter your CRM, skew your data, and can lead to awkward interactions with prospects. While ActiveCampaign is great at preventing duplicates with the same email address, copies of contacts can still appear when people use different emails. We're here to guide you through not just cleaning up existing duplicates in ActiveCampaign, but also preventing them from ever being created.
Duplicate records aren't just a minor annoyance; they actively undermine your sales and marketing efforts. They lead to inaccurate reporting, wasted time for your sales reps who might engage the same lead twice, and a fragmented view of your customer's journey. Common causes include:
ActiveCampaign automatically prevents duplicate contacts that share an identical email address. The real challenge is identifying the same person who exists under two different email addresses. Since ActiveCampaign doesn't have an automated tool to flag these, identification is a manual process. We recommend periodically scanning your contact list for similar names or searching for variations of a prospect's name to spot potential duplicates.
Once you've identified a duplicate pair, merging them is straightforward. Remember, this action is permanent and cannot be undone, so be certain before you proceed. Here’s how to do it:



It's important to note that ActiveCampaign does not offer a bulk duplicate merging feature. You can only merge two contacts at a time. This manual process can be incredibly time-consuming for businesses with large-scale duplicate issues, which highlights the importance of preventing them in the first place.
LinkActive is a Chrome extension that finds verified contact information from LinkedIn and adds standardized data to ActiveCampaign. It's the most effective way to prevent duplicates because it ensures the data entering your CRM is clean, accurate, and consistent from the very start. By automating data entry, you eliminate the human errors that cause most duplicate records.
Spending hours manually merging contacts is a reactive, inefficient process. It's a constant chore that pulls your team away from selling. In contrast, using a tool like LinkActive is a proactive strategy. By ensuring every contact you add from LinkedIn is verified and properly formatted, you save countless hours of future cleanup and maintain the integrity of your sales data.
It only takes a few minutes to start building a cleaner CRM:
One of the most powerful features of our tool is its ability to prevent duplicates in real-time. When you're browsing LinkedIn, LinkActive automatically checks if a person is already in your ActiveCampaign account. This simple check stops you from accidentally creating a duplicate record of a lead or customer you're already engaged with.
If LinkActive finds that a prospect is already in your CRM, it doesn't just stop you from creating a duplicate. It allows you to enrich the existing contact record with new, updated information from their LinkedIn profile. This ensures your data stays fresh and accurate without cluttering your database.
This real-time check acts as a safety net for your entire team. While prospecting on LinkedIn, you get an immediate visual cue telling you who is already in your CRM. This allows your team to focus on net-new leads and avoid the wasted effort that comes with pursuing duplicate contacts.
Beyond using the right tools, we recommend these best practices to maintain a clean database:
While knowing how to merge duplicates in ActiveCampaign is a useful skill, the most effective strategy is to prevent them from ever being created. A clean CRM is the foundation of an efficient sales process. By focusing on prevention with a tool like LinkActive, you empower your team to spend less time on data cleanup and more time building relationships and closing deals. At Add to CRM, we believe in working smarter, not harder.
