How to Find and Contact 100 Prospects with Apollo in One Day

Here's the exact workflow I use when setting up a new cold outreach campaign using Apollo for prospecting and Smartlead for sending.

1

Define your ideal customer profile

In Apollo's search, filter by industry, job title, company size, and location. For example: "Head of Marketing" at "SaaS companies" with "50–500 employees" in the "United States." Apollo shows you exactly how many contacts match.

2

Export your verified prospect list

Select your filtered contacts and export them with verified email addresses. Apollo validates emails before export — reducing bounce rates significantly compared to unverified lists from other tools.

3

Enrich with additional data

Use Apollo's enrichment to pull company news, recent funding, technology stack, and other signals that help you personalize your outreach. Knowing a company just raised $5M makes your opening line far more relevant.

4

Build your sequence in Apollo or export to Smartlead

For lower volume — use Apollo's built-in sequences. For high-volume campaigns at scale — export your list and run it through Smartlead with unlimited inbox rotation for better deliverability control.

5

Track replies and manage pipeline

All replies and engagement data sync back to Apollo's CRM. Mark interested prospects, schedule follow-up tasks, and move them through your pipeline without switching between tools.

Pro Tip — The Apollo + Smartlead Stack

Use Apollo for prospecting and lead sourcing — it's the best database available. Then export to Smartlead for sending — it gives you unlimited inbox rotation and superior deliverability control. Together they are the most powerful cold email stack available in 2026.

My Honest Verdict on Apollo.io

Apollo.io has become the default prospecting tool for serious cold email professionals — and for good reason. Having 275M+ verified contacts, email sequences, a CRM, and a Chrome extension all in one platform eliminates the need for multiple expensive subscriptions. I use Apollo for every new client campaign to source and verify prospects before sending. The free plan is genuinely useful — not a stripped-down teaser — and the paid plans offer exceptional value compared to buying a separate lead database and outreach tool. If you are doing any B2B cold outreach in 2026, Apollo is non-negotiable.

Important Note on Credits

Apollo's "email credits" are used to reveal verified email addresses from the database. If you already have a contact list and just need Apollo's sequencing features, you may need fewer credits than you think. The free plan's 60 credits per month is enough to test the platform and run small campaigns.

Apollo.io — Common Questions Answered

Is Apollo.io's contact database accurate?
Apollo's database is one of the most accurate available — but no database is perfect. Email accuracy is typically 85–92% depending on the industry and contact type. Apollo uses a combination of AI verification, crowdsourced data, and third-party validation. Always run exported lists through an additional email verifier like ZeroBounce before sending campaigns at scale.
Can I use Apollo for email sending or just prospecting?
Both. Apollo has built-in email sequences that work well for lower-volume outreach. For high-volume campaigns — 10,000+ emails per month — pair Apollo for prospecting with a dedicated sending tool like Smartlead or Instantly that offers unlimited inboxes and advanced inbox rotation for better deliverability.
Does Apollo replace tools like ZoomInfo or Lusha?
For most users, yes. Apollo offers a comparable database to ZoomInfo at a fraction of the price — ZoomInfo enterprise plans run $10,000+/year while Apollo's Professional plan is under $1,200/year. The data quality is very close and Apollo adds outreach and CRM features that ZoomInfo doesn't include.
How does the Chrome extension work?
The Apollo Chrome extension overlays contact information directly on LinkedIn profiles and company websites. When you visit someone's LinkedIn profile, Apollo shows their verified email address, phone number, and company details — saving you from manual research and allowing you to add them to sequences directly from LinkedIn.
Is there a free plan?
Yes — Apollo's free plan includes 60 email credits per month, basic sequence automation, the Chrome extension, and limited CRM features. No credit card required. It's enough to test the platform, source your first prospects, and run small campaigns before committing to a paid plan.
How does Apollo compare to Instantly's lead database?
Both offer built-in B2B databases, but Apollo's is significantly larger — 275M contacts vs Instantly's database. Apollo also offers more advanced filtering, enrichment signals, and CRM features. Instantly is better suited for pure cold email sending volume, while Apollo is the better choice if lead sourcing and data quality are your primary needs.
