What is waterfall enrichment?

Waterfall enrichment runs each contact through multiple data providers in sequence. If the first doesn’t have a verified email or phone, it tries the next, and the next, until it finds a match. One source covers maybe half your list; a waterfall covers far more.

From the people who use it every day

Real teams, real results. Here’s what founders, sellers, and recruiters say about LeadDelta.

  • ★★★★★
    As an early adopter, my primary goal was to organize my LinkedIn contacts in a personal CRM – to separate customers, prospects, partners, and personal contacts. Tags are perfect for this. Today, the tool can do much more and has great potential, especially for sales professionals.

    One of LeadDelta's most useful features is the ability to easily export profiles from LinkedIn, making it simpler to manage your contact list. Another useful aspect is the option to add custom notes to each contact. The only real criticism I've found of LeadDelta is the lack of automatic cloud synchronization. This means I can't access all my data from different devices. A major advantage of LeadDelta, in my opinion, is its simple and user-friendly interface. You can easily download the software as a Google Chrome extension and use it immediately. Thanks to LeadDelta's ease of use, I can also capture more high-quality leads from LinkedIn more easily.

    I appreciate how LeadDelta helps simplify the complexities of managing LinkedIn contacts. The ability to organize and structure my own LinkedIn network and efficiently send personalized messages provides a practical solution to my challenges. The integrated LinkedIn interface is particularly impressive!

    For me, the best browser CRM for LinkedIn The best feature is the ability to filter contacts according to numerous relevant criteria, along with the tagging and task functions. This allows you to maintain an optimal overview and communicate effectively with your network. Another highlight is the ability to unfollow or remove multiple contacts simultaneously using the filtering and batch function if they are no longer relevant. A huge plus is the message inbox, mirrored from LinkedIn, which is much larger and more user-friendly. Here, too, you can tag and filter messages. Future plans include the integration of CRMs with LeadDelta, which will further enhance efficiency. I'm still missing some filter functions to more quickly find active LinkedIn users or to identify users with many or few followers. A folder function in the Messenger inbox would also be great. I've been with LinkedIn since day one, and the feature development is fantastic. I can keep track of my network. I can identify and tag leads and make notes on relevant contacts. The new task function lets me set up tasks and reminders. The biggest advantage is that I have all my contact information at a glance and can use it to reach out to them. Network maintenance and hygiene are also possible thanks to the numerous filter functions. And the messenger is much clearer than LinkedIn's small windows.

    With LeadDelta, I keep LinkedIn under control. LeadDelta stands out for its exceptionally clear structure, particularly its features for selecting and tagging multiple contacts. The seamless integration of these features into the LinkedIn interface enables a highly intuitive and efficient workflow. For example, contacts can be tagged and notes added directly within LinkedIn. An additional benefit is the ability to add individual, custom notes for each contact. These functionalities contribute to making working with LeadDelta not only efficient but also extremely user-friendly. The only real improvement suggestion I have for LeadDelta concerns the lack of automatic cloud synchronization. This means that accessing all data from different devices is not possible. It would be really great if you could consider adding this feature! The tool is available as a simple Google Chrome extension for immediate download. Thanks to the intelligent tagging function, I can find my direct contacts in no time. The structured organization of my contacts allows me to contact them directly via LeadDelta on LinkedIn. Message management is significantly more efficient compared to the LinkedIn platform itself.

    Die Funktionserweiterung für LinkedIn und LinkedIn Sales Navigator, die ich schon seit Jahren vermisst habe! Nachrichten und Kontakten lassen sich Tags zuweisen und so einfach filtern, nachverfolgen etc. Super praktisch ist auch die Funktion, Feeds und Updates von bestimmten Personen separat nachzuverfolgen (statt den kompletten LinkedIn-Feed inklusive Werbung etc. gemischt).

    I was using the Lead Delta 7-day trial and developed questions. Their representative was helpful. All my questions were answered in chat and email. Lead Delta also has extensive information about their service in their website’s help section. I chose the pro subscription because I am new to LinkedIn and networking. My school assigned career specialist was impressed with Lead Delta’s capabilities and intends to inform other students about this helpful service. During my 7-day trial, I found the interface intuitive. Managing my LinkedIn contacts has become as simple as managing bookmarks with Bookmark Ninja. Everything is laid out in an open space for a clear view. Specific contact information opens on the right vertically. Space is efficiently utilized. And the optional LinkedIn sidebar feature is impressive. As a recent graduate seeking employment, I can’t afford to take risks with financial decisions. With a supportive environment, clearly detailed help information on their website, and friendly customer service, I felt confident that Lead Delta would effectively support my LinkedIn networking needs. Thank you, Lead Delta!

    LeadDelta is the tool everyone should use if they take LinkedIn seriously. It makes networking so much easier and lets me see my network the way I want, with filters and tags, and I can easily view my network breakdown by location, title, and industry. It's a no-brainer, so download today and thank me later.

    I have used multiple productivity tools for Linkedin but none compare to LeadDelta´s unique CRM capabilities. A real treasure. Since implementing LeadDelta in my daily workflow, I´ve been able to reach out to my Linkedin contacts using just LeadDelta, no need to bring in any other communication or contact management tool, so I am saving tonnes of time, and I am achieving better results, faster.

    The way it's pulls the data from Linked in so quickly is amazing. You can create custom tags and use templates. The chrome plugin is another bonus! Bulk Messaging is available too. Looking forward to integrations. I've been able to segment my contacts from different industries, much easier than sifting through LinkedIn manually. Time to prune my linked in contact base!

    Thanks Leaddelta Team for finally creating a tool to manage my LinkedIn Network in a more efficient way!!! 🙏🏻
    Jens Polomski
  • ★★★★★
    Networking is hard. It's a lot of work to maintain relationships with people you don't often interact with, and it's easy to forget about them altogether. That means that your network can become fragmented over time and the people in it will have less incentive to stay connected with you. This leads to missed opportunities for collaboration or even lost business opportunities down the road. That’s where LeadDelta comes in. It imports all your 1st degree connections into the platform so you can focus on doing the work rather than getting distracted on LinkedIn. You can add tags to different prospects, filter to find specific groups of people and send bulk personalized messages to them. And the best part? They strive to become fully compliant with LinkedIn terms and conditions. That means you won’t have to worry about breaking LinkedIn rules or getting your account suspended.
