"1) it is highly scalable and you can easily send out thousands of emails per day, 2) it’s a fairly “democratic” form of outreach where you can achieve great outcomes with good offers sent to the right people, and 3) there’s no platform risk."

From a European citizen point of view, this framing ignores a very real constraint: GDPR.

In the EU, sending marketing emails is not just a growth tactic, it is regulated personal data processing. In most cases, you need prior, explicit consent before sending promotional emails. “We found your email online” or “legitimate interest” is usually not enough for cold outreach aimed at sales.

The risks are not theoretical:

Administrative fines that can reach up to 20M EUR or 4 percent of global annual turnover.

Orders to stop processing, which can immediately kill an outbound pipeline.

Domain and IP blacklisting by European ISPs and email providers.

Blocking or delisting of websites and services in the EU market after regulator or court decisions.

Complaints to Data Protection Authorities by a single recipient are enough to trigger investigations.

So there is very much platform and regulatory risk, at least if you want access to the European market. Email is scalable, yes, but in Europe it scales legal exposure just as fast if consent, proof of consent, opt-out mechanisms, and transparency obligations are not handled correctly.

This is why many EU companies invest heavily in permission based lists, double opt-in, and strict compliance processes. Growth without compliance is not “no risk”, it is deferred risk.
