Looking for Seamless.ai alternatives? Here are 10 great options

Seamless.AI not your bag?

While it offers strong automation and data enrichment features, it can be clunky, complex, and pricey.

Fortunately, there are many other sales outreach tools that offer similar functionality without the drawbacks. 

Why Consider Alternatives to Seamless.AI?

Seamless.AI Comparison Table

Seamless.AI (Seamless for short) is an AI-driven data enrichment and outreach tool that automates lead verification, lead scoring, and email outreach. 

The tool has good sides—we can’t argue with that. But there are negatives. Let’s quickly explore both sides of the coin. 

Seamless.AI Pros

Knowing what Seamless does well gives you a clear picture of the features to look for in other tools.

Here are the upsides of using Seamless:

  • Strong data enrichment 

  • Automated multi-channel outreach

  • Advanced pitch intelligence

  • “AI Autopilot” for generating lead lists 

In short, it’s a comprehensive platform that allows brands to run personalized, multi-channel campaigns.

Seamless.AI Cons

Despite the extensive automation and AI features, Seamless falls short in some areas. 

Here are the most common complaints about Seamless:

  • Inaccurate data

  • Poor customer support

  • Too much complexity

  • A wasteful credit-based payment system

Getting to grips with the platform can feel like a mammoth task—time-consuming and without visible results.

1. Artisan

The platform is AI-first, with a virtual BDR, Ava, who handles all the early and middle stages of the outbound sales cycle, including lead generation, personalized outreach, and follow-ups. This gives your team space to focus on the essential human moments, such as calls, meetings, and demos.

2. ZoomInfo

ZoomInfo Homepage

ZoomInfo is a sales intelligence platform with a vast lead database and advanced search and filtering capabilities. Its AI also scores lead intent and summarizes conversations, saving sales reps’ time.

This is a tool for verifying emails, gaining insights, and finding accurate contact details. It won’t handle outreach.

A key feature is “Scoops,” a data enrichment tool that trawls news sites to identify pain points and relevant news, such as layoffs or extensive hiring, for use in outreach and sales calls. 

ZoomInfo is a good fit for mid-market and enterprise brands, and the costs match this target market. 

Key Features

  • Database containing 70 million phone numbers and 174 million verified email addresses to accurately prospect B2B leads

  • Detailed lead search filters, including industry, seniority, and revenue

  • Integration with many tools, including Salesforce, HubSpot, and Outreach

  • AI Copilot for prospecting that offers lead summaries, email generation, and lead prioritization

  • Chrome extension for on-the-go lead discovery while browsing LinkedIn and company websites

Pricing

ZoomInfo doesn’t release pricing plans. Contact the sales team for more information. 

3. Apollo.io

Apollo

A popular B2B tool, Apollo, streamlines your whole sales process, with features for everything from multi-channel outreach to reporting. Apollo is somewhat unique in that it's popular with both small and large companies. 

Apollo automates the bulk of the outreach process, including lead scoring, cold emailing, and follow-ups. The large database has several advanced search features and allows you to create customized lead lists. Plus, you can easily adjust workflows to fit your needs. 

All of that said, issues around data quality have led many customers to seek alternatives to Apollo

Key Features

  • Contact database containing over 210 million entries

  • Regular data hygiene checks

  • Chrome extension for lead discovery via LinkedIn

  • Integration with HubSpot, Gmail, and Salesforce 

  • Feature called Intelligence Engine for analytics and reporting

  • API for CRM data enrichment 

Pricing

  • Basic: $49/user/month

  • Professional: $79/user/month

  • Organization: $119/user/month

A limited free tier allows sales professionals to use 1,200 credits per user per year. 

4. HubSpot Breeze (formerly Clearbit)

HubSpot (Breeze) Homepage

Breeze Intelligence is a prospecting tool that’s part of the extensive HubSpot mega-machine. It aims to make selling easier by enriching data from reliable sources and tracking web visitors. 

Offering quick access to technographic and firmographic data, this tool is particularly valuable for businesses struggling to personalize messages. 

However, it isn’t an all-in-one platform like Seamless. Breeze is a better fit for businesses already using HubSpot, especially growth-stage companies requiring clearer insights. 

Key Features

  • Real-time data enrichment for deeper insights, such as firmographics and technographics

  • Website visitor tracking to capture leads

  • Easy integration with HubSpot

  • APIs for custom enrichment and automation workflows

Pricing

  • Small: $45/month

  • Medium: $270/month

  • Large: $900/month

Breeze Intelligence is available as an add-on to existing HubSpot subscriptions or as part of the “Smarter Customer Platform” bundle for startups and small businesses. 

5. Clay

Clay homepage

Clay offers AI-powered data enrichment, digging into over 100 data providers to provide insights in real time. Its wide data coverage that incorporates other providers is one of Clay’s biggest selling points. 

Clay’s database filtering is one of its most popular features. It allows you to “get granular” to find the right leads. It also creates lead lists, stores intent data, and handles lead scoring. 

This tool has many automated inbound and outbound sales automation features, including personalized messaging.

6. LinkedIn Sales Navigator

LinkedIn Sales Navigator Homepage

If your leads prefer LinkedIn, Sales Navigator is a cheat code for accessing them. You can benefit from the reliability of the social platform’s first-party data for 500 million professionals and search using over 50 filters. 

It’s a breath of fresh air if Seamless’ unreliable data left you frustrated. However, this tool is limited when it comes to channels beyond the B2B social media platform. 

Key Features

  • Integrations with CRM tools, such as HubSpot and Salesforce

  • Reliable first-party data

  • Segmentation for personalized outreach

  • Increased InMail credits

  • 500 million contact database with an array of filters

7. Hunter.io

Hunter Homepage

Hunter is a sales tool for companies prioritizing email outreach. It provides templates with custom fields for automated data population. It also warms up leads and verifies data to help you maintain a high deliverability score. 

Hunter provides a Chrome Extension for capturing leads while browsing LinkedIn, and “Domain search,” which finds employee emails based on company domain searches. 

However, this isn’t a tool for multi-channel campaigns, and its database is on the smaller side, with only 100 million contacts.

Key Features

  • Database containing over 100 million profiles

  • Domain search and Chrome extension for quick lead insights

  • Email Finder and Verifier for reliable contact discovery

Pricing

  • Starter plan: $49/month

Plans come with a specified number of seats, which can be increased for an additional $10/month/user.

8. Cognism 

Cognism Homepage

Cognism is a B2B sales intelligence platform that provides high-quality data that’s compliant with European regulations. 

Its Diamond Data verification feature ensures high accuracy for email and phone numbers. Plus, data is regularly hygiene-checked.

Cognism also tracks intent signals, so you can prioritize leads who are most likely to buy. However, this tool doesn’t support automated outreach. You’ll need to integrate another platform, such as Outreach or HubSpot. 

Key Features

  • GDPR-compliant database with over 500 million B2B contacts

  • Extensive filters and intent analysis for prioritized, personalized outreach

  • Chrome extension for LinkedIn lead discovery

Pricing

Contact the sales team for a custom quote.

9. UpLead

UpLead Homepage

B2B data provider UpLead is tailored to the U.S. market. The database is smaller than average, with 108 million contacts, but each entry is supplemented with deep insights into tech stacks, revenue, and job functions. Interestingly, it promises 95% data accuracy thanks to its human experts.

UpLead uses a credit model like Seamless. However, pricing is transparent. There are integrations with CRMs and for exporting data, but it’s not an end-to-end tool.

Key Features

  • Email verification 

  • US-tailored database of over 100 million contacts

  • Over 50 search filters for accurate lead discovery

  • Extensive data enrichment

Pricing

  • Essentials: $99/month

Snov is a limited tool designed for smaller teams running multi-channel campaigns on a budget. It has email discovery, data verification, and outreach automation features. It also supports lead tracking and management throughout the funnel.

Snov’s Chrome Extension is good for lead discovery when visiting company websites and LinkedIn. Plus, email warm-up and deliverability features help keep your emails reaching leads. 

Key Features

Which Seamless.AI Alternatives Should You Explore?

Seamless is a powerful tool for automating the sales process. But unreliable data, poor customer support, and a web of complexity put off many teams. 

ZoomInfo, Cognism, or UpLead may be welcome alternatives for teams needing data enrichment. 

Want a fully automated, all-in-one tool? Artisan has everything you need. AI BDR Ava filters leads from a database of over 300 million entries to find leads who perfectly match your ICP. From there, she automates all of the early and middle stages of the outbound sales cycle, matching (and even surpassing) the quality of a human SDR.
