What is a B2B SaaS leads database?

A B2B SaaS leads database is a searchable collection of verified software-as-a-service companies with contact information, firmographic data, and technology signals. port587's database contains over 100,000 verified B2B SaaS companies that can be filtered by industry, geography, company size, revenue, and funding stage.

How much does the port587 leads database cost?

port587 uses pay-per-lead pricing with no subscriptions. Credits start at $49 for 1,000 leads (~$0.049/lead) and go down to ~$0.02/lead at agency volume (50,000+). Credits never expire, and you only pay when you export contact data.

Where does the data come from?

Leads are sourced from publicly available business directories, LinkedIn, and verified B2B data providers. All data is regularly cleaned, deduplicated, and validated through automated email verification and website enrichment.

How is port587 different from Apollo or ZoomInfo?

port587 is a pure data layer, not an all-in-one platform. You pay only for the leads you export (no seat-based subscriptions), use your own outbound tools, and own your data in CSV or JSON format. Unlike Apollo and ZoomInfo, there are no forced bundles of sequencing, CRM, or calling features.

No. Credits never expire. You buy them once and use them whenever you need to export leads.

Yes. You can create an API key from your dashboard and integrate lead search directly into your tools and workflows via the REST API.

What formats can I export?

Leads can be exported as CSV or JSON, ready for import into any CRM, enrichment tool, or spreadsheet.

Can I cold email people from a purchased list?

In the US, yes — CAN-SPAM requires an accurate sender identity, a physical address, and a working unsubscribe mechanism. In the EU/UK, GDPR requires a legal basis (typically legitimate interest for B2B), transparency about data use, and easy opt-out. In Canada, CASL is stricter and generally requires prior consent.

Is Buying B2B Email Lists Legal?

US: CAN-SPAM

CAN-SPAM does not prohibit buying email lists. It regulates how you send:

Include your physical mailing address.
Provide a working unsubscribe link.
Use accurate sender information (no misleading "From" names).
Honor opt-out requests within 10 business days.
Don't use deceptive subject lines.

As long as your emails comply with these requirements, sending to a purchased B2B list is legal in the US.

EU & UK: GDPR

GDPR is stricter but does allow B2B cold email under "legitimate interest" (Article 6(1)(f)):

You must have a legitimate business reason to contact someone (e.g., your product is relevant to their role).
You must be transparent - explain how you got their data if asked.
You must provide an easy way to opt out.
The person must have a reasonable expectation of being contacted in a business context.

GDPR applies to the individual, not the company. Business email addresses (name@company.com) are treated differently from personal emails in many EU member states.

Canada: CASL

Canada's Anti-Spam Legislation (CASL) is the strictest major framework:

Generally requires prior express or implied consent before sending.
Implied consent exists if you have a pre-existing business relationship (e.g., they bought from you in the last 2 years).
Cold emailing without consent is riskier under CASL than under CAN-SPAM or GDPR.

Best practices for purchased lists

Use verified data - buy from sources that validate email addresses. Sending to invalid addresses damages your domain reputation regardless of legality.
Include unsubscribe links - required by all major frameworks.
Be transparent - if someone asks how you got their email, have a clear answer.
Honour opt-outs immediately - this is both a legal requirement and a reputation issue.
Focus on business relevance - your email should be relevant to the recipient's role. This is both a legal best practice and a conversion best practice.

The legality question is usually the wrong concern. The real question is data quality: are the emails valid, are the companies a fit, and will your outreach be relevant? Bad data creates legal risk (bounces, complaints) even when the purchase itself is legal.
