How to find a prospect's email in the US: 10 tools and the CAN-SPAM rules

By The AIGrowthRank team, published October 28, 2026, updated October 28, 2026

Ten tools to find or verify a prospect's business email for outreach in the US, with prices checked on October 28, 2026 on the official pages. Before the tools: what the CAN-SPAM Act requires in every email, how California's privacy law treats work contacts, and how this differs from the consent rules in France.

What CAN-SPAM requires before you hit send

The FTC compliance guide to the CAN-SPAM Act says the law covers all commercial email, not just bulk email, and makes no exception for business-to-business email. A cold email that promotes your product or service to a prospect is a commercial message.

The guide lists the main requirements:

• Header information (From, To, Reply-To and routing) must be accurate and identify the person or business that sent the message.
• The subject line must reflect the content of the message.
• You must disclose clearly that the message is an advertisement. The law gives you a lot of leeway in how you do it.
• The message must include your valid physical postal address. A street address, a P.O. box registered with the U.S. Postal Service or a registered private mailbox all work.
• The message must explain clearly how to opt out of future marketing email from you, with a return email address or another easy Internet-based way to do it.
• You must honor an opt-out within 10 business days, and your opt-out mechanism must keep working for at least 30 days after you send. You cannot charge a fee or ask for more than an email address to process it.
• Once someone has opted out, you cannot sell or transfer their address.

The list of requirements does not include asking for permission before the first email. The law gives recipients the right to have you stop emailing them. If you hire an agency or a tool to send for you, you stay legally responsible, and both the company promoted in the message and the company that sends it can be held liable.

Each separate email that violates the law can lead to penalties of up to $53,088. The guide also lists aggravated violations that can lead to criminal penalties. One of them is harvesting email addresses or generating them through a dictionary attack, which the FTC describes as sending email to addresses made up of random letters and numbers in the hope of reaching valid ones. The email finders below start from a real person and a real company, and most verify the address before you use it.

State privacy laws: California first

State privacy laws apply to the personal data in your prospect list, in addition to CAN-SPAM. The California Attorney General's CCPA page (updated August 28, 2026) says the CCPA applies to for-profit businesses that do business in California and meet one of three thresholds: gross annual revenue over $25 million, buying, selling or sharing the personal information of 100,000 or more California residents or households, or earning 50% or more of annual revenue from selling California residents' personal information.

The exemption for personal information reflecting business-to-business transactions expired on December 31, 2022. Since then, a California prospect whose work email sits in your CRM can, if your business is covered, ask to know what you hold about them, ask you to delete it, correct it, and opt out of its sale or sharing.

California also regulates data brokers. Under the Delete Act, since August 1, 2026, registered data brokers must check the state's Delete Request and Opt-out Platform (DROP) at least once every 45 days and process consumer deletion requests, according to the California Privacy Protection Agency. Apollo, in this list, describes itself as a registered business-to-business data broker. A contact you found last year may disappear from a database after such a request.

Not every state treats work contacts this way. Virginia's privacy law, for example, defines a consumer as a resident acting only in an individual or household context and excludes a person acting in a commercial or employment context (Va. Code § 59.1-575). Check the law of the state where your prospects live, and ask a lawyer if your volumes are large.

How this differs from GDPR and the CNIL in France

In the US, the default for B2B email is opt-out: you can send a first compliant email, and you must stop when asked. In France, the CNIL page on email marketing sets prior consent as the general rule for consumers. For professionals, prospecting can rely on the sender's legitimate interest when the message relates to the person's job, and the person must have been informed and be able to object. On October 16, 2026, the CNIL also published a guidance sheet on reconstructing work email addresses (guessing firstname.lastname@company) The CNIL asks the sender to check, case by case, whether the person could reasonably expect their work address to be reconstructed. If you prospect in France, our French guide covers those rules and the European tools.

How this list is made

We kept ten tools whose official website offers finding or verifying business email addresses and that suit prospecting in the US. Prices were checked on October 28, 2026 on the official pricing pages and are shown in US dollars, as the pages display them. We have not tested these tools. In each section, the order follows our provisional ranking for the Prospecting messages use case, then alphabetical order. None of these ten tools has an affiliate link with us.

Find an email from a name and a company

Hunter is fourth in our Prospecting messages use case, and our pick for a zero budget. Its Email Finder first looks for a match among email addresses found publicly on the web. If there is none, it considers the likely permutations of the person's name on the company domain, then runs an email verification on the result.

The free plan gives 50 credits per month, used for the Email Finder, the Email Verifier and Domain Search.

B2B contact databases

These six tools give you access to a database of business contacts with search filters, so you can find prospects by job title, industry or location before you have names. Several also offer a Chrome extension. Section 8.2 of the LinkedIn User Agreement forbids using software, browser plugins or add-ons to scrape or copy profiles and other data from LinkedIn. LinkedIn's help page on prohibited software and extensions adds that members who use such tools risk having their accounts restricted or shut down. We rate Apollo and Lusha as grey area for this reason. If you use them, search in their database or from your CRM, not on LinkedIn profiles.

Verify a list you already have

If you already have addresses, verify them before you send. Hunter's credits also cover its Email Verifier, Anymail Finder charges 0.2 credits per check, and Findymail has its own Email Verifier. Keep a suppression list of everyone who opted out, because CAN-SPAM gives you 10 business days to honor a request, and load it into every tool that sends for you. UpLead's Plus plan accepts suppression list uploads.

Which tool for which case

• A few addresses a month for free: Hunter (50 credits per month), Prospeo (100 credits per month) or Lusha (40 credits per month).
• Pay only for results: Anymail Finder (charged only for verified emails) or Voila Norbert (only successful finds count).
• A fixed monthly price without counting credits: Findymail, from $99 per month.
• Prospects to find by job title or industry, without names: a database such as Apollo, Lusha, RocketReach or UpLead, or Anymail Finder's decision maker search.
• A large sales team that wants a custom package: ZoomInfo.

Not in this list

Snov.io finds and verifies emails, but its pricing page lists "LinkedIn automation" among its outreach features. We left it out until we review it against LinkedIn's rules. lemlist is first in our Prospecting messages use case, but it is a multichannel campaign platform and its automated LinkedIn steps put it in the grey area. Seamless.AI is also in the grey area in our data and its prices are not verified. European tools such as Dropcontact, Icypeas and Kaspr are covered in our French guide.
