Apollo.io:

Apollo.io is a B2B sales intelligence and engagement platform that provides access to various tools for searching, filtering, engaging, and tracking everything in one place. It helps by offering high-quality, intent-driven contact data, outreach automation, and workflow integration to sales reps, marketers, founders, and SDRs.

It’s a comprehensive pipeline-building engine, not just a database.

What is it best for?

• It is best for cold outreach without a sales team, done by founders.
•  It is best for startups and scale-ups that need verified emails and phone numbers instantly.
• It is best for the marketing team as it targets the decision makers by role, industry, or company stage.

Key Features:

• Massive B2B contact database: it can access up to 275M+ contacts, and 70M+ companies. It is filtered by the role (e.g., CEO, Marketing head), Seniority (Manager, VP, director), location, revenue, funding, tech stack, and hiring trends.
• Intent prospecting: To find a solution to our problem, this tool uses the buyer intent filters to help companies that are actively searching for our solution.
•  Verified emails and phone numbers: The business emails and the direct dial, which may be US and global, are verified in real time to reduce their bounce-back rates. In this way, the business emails and the direct dials are validated.
• Chrome Extension: This tool is available on Windows as a Chrome extension. With the help of this extension, we can view the contact information directly on LinkedIn. It works with a LinkedIn sales navigator and ads leads to Apollo with one click as well.

Cons:

One of the main disadvantages of using Apollo.io is its data inaccuracy; it sometimes gives inaccurate contact information or outdated data, even phone numbers. Another disadvantage is the LinkedIn profile restriction; when someone is excessively active on LinkedIn, that activity looks suspicious to LinkedIn and activates LinkedIn restrictions, especially when someone is trying to reach out to clients through LinkedIn. Another disadvantage is its very strict refund policy; people might not get a refund even when they are not happy with its services.

Clay:

Clay is a powerful no-code data enrichment and automation tool with a strong emphasis on B2B lead data and AI-powered personalization. It helps us to build up complex workflows visually and involves personalization; it not only finds but also enriches and qualifies the leads.

Key Features:

50+ data sources of enrichment: Using a vast library of data providers, Clay helps us enrich the data. Clay helps you to enrich the data, like

• Firmographics (Industry, size, revenue)
•  Technographics (tools used, e.g., Shopify, HubSpot)
• Contact data (email, phone numbers, social links)
• Intent data (job changes, funding rounds, hiring intent)

Use case example:

For example, if we start with the list of company names, the tool will automatically pull up the LinkedIn pages, and it will enrich their contact-based data. It will automatically identify the decision makers with the email and verify their emails, and personalize outreach with the recent news.

• No-code workflow: Clay drag-and-drop the visual interface to build automation workflows and custom enrichment.
• Components:  One of the components is tables, which is similar to Google Sheets or Airtable. We can add the rows and columns manually or via integration, where each column can run an enrichment or logic. It performs actions like sending emails, triggering Webhooks, or populating the CRMs like HubSpot or Salesforce.
• Custom APIs + AI + Webhooks: We can call any external API, even if they’re on an internal database or webhook. We can add Open AIGPT columns to generate LinkedIn profile insights, job summaries, and icebreakers, which trigger outbound emails or CRM updates in real time.
• Integration: Clay connects with Outreach, CRM, Sheets, and Storage, automation, and AI.

Revenue-Based B2B:

Revenue-based B2B is a new technology that helps to find out who exactly is visiting our website, and it tells us about the specific person visiting the website, and not just the company.

This is a very unique and different tool compared to Google Analytics or IP tracker. Those can only tell us about the company name or location, but a revenue-based B2B tool is something that tells us about who exactly visited our website, it tells us about the visitor, what company they work at, their role or seniority level at the company, what pages they have visited and their contact information, like email or LinkedIn.

How does it work?

You might have noticed that when you visit a website, you get the option to choose whether to reject all cookies or select all cookies. Those cookies are there to track your online presence, but RB2B Tech works by combining cookieless tracking, device fingerprinting, and massive identity graphs.

The basic process is that the user visits your website, and RB2B Tech analyzes device or browser behavior without using cookies. RB2B cross-checks the data with the databases of known online identities. If the data in the database of known online identities matches, it gives a person’s name, role, company, verified emails, LinkedIn, and visit behavior.

Why is it so powerful?

It is very powerful because it helps us know which companies brought in top decision-makers. It personalized the follow-up emails based on what pages they had visited, and it reached out to the high-intent visitors even if they didn’t fill out a form.

Snov.io:

Snov.io is a powerful B2B data tool to find, connect, and sell to other businesses. It gives access to 28 million professional contacts, who are real people working at real companies across the world. It helps us build the targeted list of people based on their job title, industry, location, country size, or revenue, and the technologies the companies use.

What is in the 28 million record database?

This database includes the names of professionals, job titles, and seniority levels, company name, verified business email addresses, LinkedIn profile links, phone numbers, and company tech stack, whether they use Shopify or Salesforce, etc. We can find hundreds and thousands of leads in seconds, and instead of searching them manually on LinkedIn or Google.

What can you do with it?

This tool can help you make a sales team by finding decision-makers and reaching out to them directly. It can get a wide access to the qualified professionals, and create cold email campaigns or ad audiences. It validates your market or reaches out for a partnership.

Is the data even verified?

Absolutely. The data is valid, and contacts are up-to-date, because this tool uses multiple verification methods. It helps us to avoid the high bounce rate when we are sending emails.

Instantly AI:

Instantly AI is a tool that helps businesses in sending cold emails while making sure that those emails land in the inbox and not the spam folder. It is widely used in sales campaigns, lead generation, and B2B Outreach.

Email deliverability:

Email deliverability refers to the delivery of email to the main inbox rather than the spam or promotion folder. The cold emails can get flagged as spam if:

•         Send too many emails at once
•         If the email account is new or has a low reputation
•         If the email content looks spammy

How instantly improves the deliverability of emails?

Firstly, we have to warm up our email account and send or receive small, real-looking emails daily. Warming up our email account will build the sender’s reputation with Google or Outlook.

This tool checks our content and our subject lines to detect content that might trigger spam filters. It tells us how well our emails are performing by giving us the real-time reports, which give reports about open rates, reply rates, and bounce back rates of emails.

Inbox rotation:

Inbox rotation is a smart feature that uses multiple email accounts automatically to spread our outreach. It works by sending emails from various accounts rather than sending emails from one account.

This also helps us to avoid reaching Gmail or Outlook’s sending limits. It protects our account from getting blocked and keeps our sending volume high without hurting our domain.

How to pick the right lead Finder:

There are three things to find the best B2B lead Finder:

1. ICP (ideal customer profile)
2. Budget
3. Tech stack

ICP:

To find our ideal customer profiles, we can use the various tools. If we want high-volume contacts, we can use tools like Apollo, Snov, or Instantly, which are great tools for high-volume contacts. To find high-quality decision-makers, we can use tools such as Clay, ZoomInfo, or Cognism.

Budget:

Low budget: Use Snove.io, LeadRocks, or Skrapp if our budget is less than 100$/month.

Mid-tier: If our budget is between 100 to 500 dollars per month, then we can use the tools like Instantly, Apollo, and Clay.

High budget: If our budget is more than $1000 per month, then we can use tools like Zoom Info, Cognism, and Lusha Enterprise.

Match your tech stack:

Instead of using a tool that doesn’t integrate directly, use a tool pick which integrates directly. Instead of sending tons of emails on your own from only one account, use warm-up and inbox rotation tools for smooth emails.
