Instantly vs. LeadFuze

Last updated on

Reviewed by Paddy Stobbs

PS

Instantly and LeadFuze serve distinctly different needs in the lead generation market. Instantly excels as an all-in-one sales platform with strong native email capabilities, superior data verification, and comprehensive list management features, making it ideal for SMBs seeking an integrated solution for high-volume outbound campaigns.

LeadFuze, while offering a larger contact database and better browser integration, functions primarily as a basic contact database requiring third-party integrations for core features. Choose Instantly for a comprehensive sales engagement platform, or LeadFuze for pure contact sourcing with existing email/CRM tools.

Advantages of Instantly

Instantly is significantly more functional as an all-in-one platform
We found Instantly offers a much more comprehensive feature set compared to LeadFuze's basic contact database. While LeadFuze requires third-party integrations for core features like email sequencing, Instantly provides native email engagement, CRM functionality, and contact management tools all in one platform. This is particularly valuable for SMBs looking to streamline their tech stack.
Instantly provides better data verification and enrichment
Instantly offers real-time email verification with clear valid/risky/invalid status indicators, while LeadFuze lacks explicit verification indicators. Additionally, Instantly can enrich existing records with missing information, which LeadFuze cannot do. This makes Instantly more reliable for teams prioritizing data quality.
Instantly offers superior email campaign capabilities
While testing, we found Instantly's native email sequencing features to be particularly strong, with unlimited email accounts and sending capacity, plus built-in email warmup functionality. LeadFuze completely lacks native email capabilities and requires integration with third-party tools like Mailshake. This makes Instantly much better suited for teams running high-volume outbound campaigns.
Instantly has superior list management capabilities
Instantly's list management functionality is more sophisticated, allowing teams to create custom fields, share searches, and integrate lists directly with engagement tools. In contrast, LeadFuze's list management is basic, lacking features like custom fields or search sharing. This makes Instantly better for collaborative sales teams.

Advantages of LeadFuze

LeadFuze has significantly larger database coverage
LeadFuze's database of 500M contacts and 14M companies globally offers substantially more reach than Instantly's 160M contacts. This broader coverage is particularly valuable for teams targeting niche industries or expanding into new international markets.

Instantly is best for

  • Businesses with high prospecting volume (1000-5000 leads per month)
  • Who need comprehensive email engagement capabilities and native CRM features
  • And/or who want very high email sending limits

LeadFuze is best for

  • Businesses with moderate prospecting volume (200-1000 leads per month)
  • Who need a straightforward contact database with automated list building via AI bot
  • And/or who want core CRM integrations but plan to use separate tools for email outreach and engagement

Instantly is less good for

  • Businesses with low prospecting volume (50-200 leads per month) who don't need a full sales engagement platform
  • Who need advanced enterprise features like territory management, lead scoring, and org charts
  • And/or who want deep integrations with sales engagement platforms like Outreach and Salesloft

LeadFuze is less good for

  • Businesses with high prospecting volume (1000+ leads per month) who need comprehensive lead generation capabilities
  • Who need native email sequencing, lead scoring, and advanced workflow automation without third-party integrations
  • And/or who need advanced data quality controls like verification status tracking, data freshness monitoring, and partial record enrichment

Functionality

Functionality

8/10

<p>As a lead generation platform, Instantly is rounded and covers a lot of adjacent sectors beyond just lead generation. It covers the basics relatively well - including a large contact database and granular prospecting filters.</p><p>Additionally, its adjacent functionalities are also well executed such as its native email engagement/warm up features and its CRM toolkit. On occasion we noticed some missing features that are present in more focused competitors, for example, company profile pages are omitted entirely and features for larger enterprises are light (such as the ability to manage/assign territories to specific sales agents).</p>
3

Functionality

3/10

<p>At the core of it LeadFuze is simply a contacts database with standard filtering options based on location, company size and role. They have an AI powered sales assistant which allows you to add a certain amount of leads to your list on a daily basis but apart from this there's not much more which is exceptional about the tool overall.</p><p>You can't even natively send email sequences, you'd need to integrate with a third party and there aren't many buyer signal metrics.</p>
Ease of Use
7

Ease of Use

7/10

<p><span style="color: rgb(0, 0, 0);">Instantly's web app is intuitive and easy to navigate. Additionally, its onboarding was simple and not overwhelming. It's core prospecting interfaces are relatively familiar amongst competitors making it easy to pick up. It would take an average SMB employee less than 30 minutes to master its use.</span></p>

Ease of Use

6/10

<p>Since it's quite a simple tool, the interface is intuitive and all the features/filtering options are visible and easy to find. The onboarding is not overwhelming and would take a user around 30 minutes to get familiar with the setup.</p>
Look and feel
7

Look and feel

7/10

<p>Instantly's design aesthetic is modern and clean. Unlike many competitors, we found most pages to be well laid out and not overflowing with information. When tested, we find its page load times to be fast (often &lt;1s) and search times to be fast as well.</p>
4

Look and feel

4/10

<p>Has a minimalistic design and is pretty neatly laid out. <span style="color: rgb(0, 0, 0);">However, the setup itself is a bit too simplistic as compared to other tools and could do with a more enriching user experience. </span></p>
Customisability
7

Customisability

7/10

<p><span style="color: rgb(0, 0, 0);">Instantly offers a number of channels for customisation, including basic ways such as creating custom campaigns (lists), custom searches or adding custom fields to prospects. There are also some deeper levels which you can customise your experience such as by connecting to OpenAI via API and creating custom prompts to do small tasks such as cleaning company names or guessing company pain points. </span></p>
2

Customisability

2/10

<p>It allows filtering through advanced search criteria allowing you to input keywords but apart from that you can't customise anything else like adding custom fields to contacts or sharing lists.</p>
Ease of Setup
7

Ease of Setup

7/10

<p>Instantly offers a simple, self-serve free trial for their platform. When tested, we found the initial setup to be simple (taking &lt;10 mins). Additionally, connecting email addresses to their outbound platform was relatively trivial too - with a one click connect feature for popular providers like Google. However, when choosing a paid plan, their pricing model is very complex with varied plans depending on if you need standalone lead generation or need some outbound sequencing functionality too.</p>
5

Ease of Setup

5/10

<p>LeadFuze offers a self-serve free trial for their platform. When tested, we found the initial setup to be more complex than needed (taking &gt;10 mins). However, the lack of any native email sequencing functionality means it doesn't take long to get the most out of the platform despite the initial friction.</p>
Customer Support
5

Customer Support

5/10

<p>You can contact Instantly's support agents via a live chat widget within their web app. When tested, we find it relatively easy to contact a real agent (&lt;30 minutes). However, we find agents to be relatively unhelpful at times, often referring to unhelpful help centre documents instead of answering questions directly. Additionally, though Instantly does provide a help centre, its articles are often light on detail.</p>
6

Customer Support

6/10

<p>There is an option which allows you to chat to the customer support team which may reply between 1-3 hours and has a pretty extensive knowledge base which you can search through and a sparsely populated user guide.</p>
Integratability
4

Integratability

4/10

<p><span style="color: rgb(0, 0, 0);">Instantly provides a number of integrations with popular CRMs (Salesforce, Hubspot) and automation platforms like Zapier. Additionally, it offers an API through which users can interact with Instantly's database directly. However, we would like to see native integrations with sales engagement platforms such as Outreach and Salesloft as well as the provision of a Chrome extension to capture leads from sites such as LinkedIn.</span></p>
6

Integratability

6/10

<p>Integrates with a bunch of useful tools like Zapier, salesforce, HubSpot and mailshake but mostly relies on these integrations for providing additional functionality which is sometimes already included in a lead generation tool, like email sequencing and adding contacts from linkedin.</p>
Ease of Migration
6

Ease of Migration

6/10

<p>Instantly offers self-serve export functionality within its web app.</p><p>Additionally, Instantly offers an API through which businesses are able to interact with their database directly - however, documentation for this remains relatively light.</p>
5

Ease of Migration

5/10

<p>You can export lead data in multiple formats and integrates with popular CRM tools which enable direct data transfer without manual exports. However there's a size limitation on lists which can be exported based on the plan that you're on and has a credit based system where each lead export consumes credits and the system may hit the maximum volume of data exports for users on low-tier plans quite quickly.</p>
