Not everyone can afford Apollo or ZoomInfo. Here are the free and low-cost methods I use to find prospect email addresses for cold email outreach.
Free methods:
- Apollo free tier: 10,000 credits per month. Enough for most solo senders. Email accuracy is solid at around 85-90%.
- Hunter.io free tier: 25 searches per month. Great for verifying individual addresses. Their domain search feature shows all known addresses at a company.
- LinkedIn + email permutator: Find the prospect on LinkedIn, get their name, then use an email permutator tool to guess the format (firstname@company.com, first.last@company.com). Verify with Hunter or NeverBounce.
- Company website: Check the About or Team page. Many companies list email addresses or you can derive the pattern from one visible address.
- Google search operators: Search "@company.com" site:linkedin.com or "email" site:company.com to find publicly listed addresses.
Low-cost methods (under $50/month):
- Snov.io starter: Good Chrome extension for finding emails from LinkedIn profiles
- RocketReach: Reliable data, good for individual lookups
- Skrapp.io: Budget-friendly LinkedIn email finder
Important: Always verify any email address before adding it to a cold email campaign. Use NeverBounce or MillionVerifier. Sending to unverified addresses inflates your bounce rate and damages your sender reputation. A few dollars spent on verification saves you from burning inboxes.

the email permutator trick is underrated. most companies use one of like 5 email formats. figure out the pattern from one known address and you can derive the rest. combine with a $20/month verification tool and you have a free data pipeline

Apollo free tier at 10K credits/month is the best value in B2B data, period. most solo senders will never exhaust that. the paid data tools only make sense when you are prospecting at serious scale or need phone numbers

wait you can use Google search operators to find email addresses? like searching '@company.com' on LinkedIn? that actually works?

the verification step is the most important part of this whole guide. I found 500 emails using free methods last month and 23% of them bounced before I ran verification. always verify before sending, no matter where you got the data
