Selling to the US From Europe: Apollo and Lead Intelligence

The European founder's question

Your market is American, your team is in Europe. Two worries come up: does the database really cover the United States, and which sending rules apply there? This article does not redo the general Apollo versus Lead Intelligence comparison: it covers only what changes when the recipient is American. For the European mirror (GDPR), read Apollo in Europe: what does GDPR ask of a founder?. For phone outreach, see Is B2B cold calling legal in the United States?.

What Apollo states, and what it does not

On its home page and its contact search page, read on September 29, 2026, Apollo states "240M contacts & 30M companies", more than 65 filters and validation of each contact through its enrichment product. These pages do not give coverage by region: nothing says which share of contacts is American, or how quality differs by country.

In practice, do not pay for the promise of a "very American" database. Run a measurable test. Take 50 accounts from your US target segment, look for the buyer role you want in each one, and count how many named contacts and verified addresses you get. That number is worth more than the advertised volume.

US sending rules for email

The Federal Trade Commission publishes a CAN-SPAM compliance guide for business. Points that matter for a European founder:

• The law "makes no exception" for business-to-business email: a commercial B2B email is covered.
• The message must include your valid physical postal address and clearly say how to opt out of future emails.
• Subject lines must not be deceptive and header information must not be false or misleading.
• An opt-out request must be honored within 10 business days.
• Each email in violation can carry a penalty of up to $53,088, according to the guide.
• For most commercial email, no prior consent is required: a real difference from the European approach, but not an exemption from the rules above.

The guide is about email. LinkedIn messages fall under other rules that this article does not cover.

Time zones: a detail that hurts the first impression

Paris and the US west coast are about nine hours apart. A message scheduled for 9 a.m. in Paris lands in the middle of the night in San Francisco, and a badly timed automatic follow-up looks like a mass campaign. In Lead Intelligence, follow-up scheduling is computed with the time zone saved on the sender's account: if you are in Paris, follow-ups follow Paris time, not your prospect's. Plan to approve each action at a time suited to US hours rather than relying on the default calendar.

Where Lead Intelligence helps, and what it does not replace

Lead Intelligence does not sell a contact database. It finds people from a LinkedIn search, a CSV import or web research, explains why an account deserves a message now, prepares an action you review, then sends from your own mailbox or LinkedIn account. An exclusion list lets you remove contacts before sending. Neither the tool nor Apollo replaces your own check of the postal address, the opt-out link and the 10-business-day deadline.

Recommended order: measure coverage on 50 accounts, fix a compliant message template, choose sending windows by recipient time, and only then decide whether your bottleneck is coverage (Apollo) or priority (Lead Intelligence).
